Subaru EJ20 Boxer engine!!!

It's fully functional as in all parts move as intended in the real thing. Do not confuse it with a real engine, as this is not.

This engine is slightly harder to print and assemble than my Toyota 22RE engine. So it is best to print or familiarize yourself with my previous models if you choose to print this one. The scale is once again 35% of the original which seems to be a good size for printing and finding fasteners that work and look right. The tolerances are a little tighter and depending on your printer the crankshaft might take some tweaking to get it right so that there is not interference while rotating.

This model has smaller engine block than the Toyota 22RE which will allow smaller printers to print it.

Please let me know if anyone finds problems with the models or instructions. If anything is unclear with the drawings, please let me know and I will update them or create new ones.

Next I would like to do the AWD transmission for this engine or a LS1. If anybody can help with providing an engine to model from, it would be greatly appreciated.

Print Settings

Printer Brand:

RepRap

Printer:

Prusa i3

Rafts:

Doesn't Matter

Supports:

Doesn't Matter

Resolution:

.2mm

Infill:

20-40%


Notes:

Everything was printed on a $200 Chinese Prusa i3 kit. So any printer should be able to print this if it has a big enough build envelope. You will need to make the decision if you want to use support or a raft. Some parts it's obvious that support will be needed. Others will need support depending on your machine. I did not need supports while printing the engine blocks but that may vary from machine to machine.

How I Designed This

Everything was done in SolidWorks using only hand measuring tools.
All parts turned intp STL files, scaled, and repaired using NetFab basic.

There are 3 different sized tensioner pulleys, do I need one of each?

Can this print on 200mm x 200 mm x 180mm

That part thing is great. Just wish it wasn't $87 :/

You don't have to buy the parts from there. You can buy them all separately from other places for probably less.

Can you ship the non printable parts to the UK?

Many thanks.

Yes, its an extra $20 USD for shipping

It would be amazing to see a exhaust manifold, turbo and intercooler , colab that with the remixed throttle body and a rotated intake manifold for an authentic look..

@ericthepoolboy Where do you source your magnets? I set them up in one of the halves and heads, and they cannot support the weight of the heads. any advice?

China is where I get them. You have to make sure that the magnets contact each other. I'm trying to source thicker magnets for the heads though.

Please help me decide which engine to do next..
I'm leaning towards the Porsche Four cam, but would like to get some input.
Keep in mind that the inline 6 cylinders will most likely
not be able to be printed in one piece on most printers.

How much will cost ship to Poland?

@ericthepoolboy <3 thanks for this! <3, still printing but looking forward for the transmission next <3 :)

Looks like the parts list may be missing the oil pump hardware?

I am not sure if anyone has posted a comment about this already, but what would be the best way to print the Engine blocks? From all orientations, I am seeing that support material will be placed in places that I won't be able to remove it very easily. I am using Cura and printing on a Robo 3D R1+. Thanks!

You should be able to print the engine blocks without support. Or print with support touching build plate and change the support angle to greater than 75 degrees.

Thank You. I'm in the process of upgrading to an E3D v6 and will attempt the blocks after I install it tomorrow. Thanks!

This is honestly one of the coolest 3d prints I've seen.
Nick work!

Comments deleted.

What is the phasing of the lobes on the camshafts supposed to be? Specifically, when assembling the camshafts where should the four lobes on the camshafts be in relation to one another.

Also, when placing the timing belt, where does each camshaft need to be in relation to the other three?

Is this an interference engine?

Non-interference engine.

@ericthepoolboy: Any update on V8 and other stuff you are working on?

ericthepoolboy - in reply to Deim

I'm working on the V8 tonight. Still waiting to see if Subaru will send me the shifter assembly for the 6 speed....

Don't know why it's taking me so long....

I am having the same issues printing the crank gear. De-selecting the "detect thin walls" option does not help either. Can't use makerware since I'm using a Taz 5 to print. Any other ideas why some of us are having this issue and some not?

Any chance I could have another member email email me a .GCD file someone used to print this successfully?

I have found a work-around it seems. In Cura, I had to change the "default" setting for shell thickness from 1.0mm to 0.26mm. This is the first time I've had to change this setting since I got my printer about a year ago.

hi:

awesome engine.... thanks for making it! question on an issue i am having with the cam gears. i am using a flash forge finder and cannot print the cam gears they fail big time. Any help or direction to get them to print right? THANKS!

[img]http://i.imgur.com/uUQjqIJ.jpg[/img]

UPDATE: bought simplify3d prints AWESOME!

Hey Eric,

I'm printing your magnificent design, but found that the Crank_Gear_scaled.stl and the Crankshaft_rear_flange_scaled.stl both have wrong angles on the mating surface with the Crankshaft_x_scaled.stl parts. The angle should be 40 degrees, but it is around 32 degrees. Could you fix it or shall I upload the repaired parts?

Thanks, Hans

did you get a resolution to this issue? I am seeing the same thing

Just saw this comment. Fixed the files and re uploaded them

where can I get the springs for the valves part named 9657K33

http://www.ebay.com/itm/272208119423?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

you will need to buy 2 of these cases as the one case contains only 12 3/8" by 3/4" springs

Where can I get the part number the springs that you labelled 9657k43

Could you do a subaru ez36D flat six next? Also some I would like to see are a porsche boxter 6 from the 1975 930.

Now, these will be harder to find, but these are some that I would explode in joy over:

A v10 from the legendary v10 era of f1. Examples are the ferrari Tipo 053, and renault rs25. Another fun one is the porsche 910 flat six engine from 1967, which beat the ford gt40 on the nurburgring, the 1978 ferrari 512 bb lm's flat 12 which sounded amazing, the nissan rb26 I6, the toyota 2jz I6, two jdm beasts, the 1976 alfa romeo 33 sc 12 (the normally aspirated version) which got pole on every race it was in thanks to its flat 12, the 1970 ferrari 312b boxer 12 engine, and the 2016 Dodge Viper ACR v10 engine.

Just some ideas ;)

I'm only a little car obsessed

Next up after the ls7 and STi transmission will probably be a Type 547 Porsche. Gonna try and work only from pictures and documentation to develops the car files. We'll see how that goes.

I just got into 3d printing. I'm a noob, but our school has a floor of MakerBot replicator 5's and I'm really getting into it. I've always been into cars, but now I'm getting into computers and 3d printing.

So I finally done all unfinished modifications and catch most of bugs on my printer and now I'm doing this awesome thing... :)
Only problem I have is finding cheap springs for this. I find some heat bed leveling springs for Ultimaker 2 whitch should be 15mm long and have about 9,2mm outside diameter... but hey are in china so it will take very long time until they came to me... And I'm worying about theyr force, I think it would be best to use some I can fully press with my fingers to make it work easy and smooth (these should have 1,2mm diameter of the spring wire itself and that is almost twice than what is in the parts list). So did someone use or try to use them?

hi there iam having a problem finding one of the parts the cam bearing caps as i cant find them on the files how do you hold down the cams

Should be with files now, it was one part that I forgot to upload originally.

@ericthepoolboy : Eric what is ETA on V8? My printers are ready & waiting. :)

I got caught up in doing the STi transmission. The V8 is done and printed, I just need to do the instructions and parts list. I'll try and work on it in the next couple days.

This is great!
If you ever feel the need to do a Honda B16 engine, that would be awesome too.

Please help
Where to I go to purchase the bearings required (623zz, 61700& 61701) for the engine.
Also the timing belt, Could i also have the specs, and where to purchase

Thank you

Unbelievable!!! Does it really work??

How many motors do I need?

Aug 8, 2016 - Modified Aug 8, 2016

didnt see if this was posted at all. but i can not for the life of me get the teeth on the cam gears and crank gear to print for shit.

any hints on what you did?

im on a wanhao di3

EDIT! it appears as tho i have figured this out. I had to disable "detech Thin walls" in the slicer printer settings.

I've had the same problem when I ran it through Cura but when I use Makerware it's printing the gears. Not sure what's that about.

i have the same Problem, Very bad prints on my Da Vinci 1.0a with original Firmware and Da Vinci slicer. oozing over the teeth .
the solution is Simplify3d, top prints. all the teet were fine.

sorry for my terrible english

regards

André

Eric, great model! I have one piece left to print and I have already started on assembly. For The Electronics what motor controller are you using? Do you have it just running off of a separate battery or did you set it up for AC? I see the motor you used is out of stock and am going to be using a different motor per another user had stated and am hoping it will fit. On the instructions only a few things are unclear. For the printed parts list its missing the bearing caps 1 and 2 for the cams. On the connecting rod diagram ITEM NO 14,15,16 are not in the picture and shouldn't be on this page. On the diagram that shows the front of the motor and all the gears ITEM NO 36 cam nut is not on the picture. I understand from the photos they go on 2 of the cam gears but this diagram should be redone to show exactly where they go. Great work and I really enjoyed the printing and building!

Also for the valve springs I was able to buy just the ones needed for this model in sets of 5 for a few dollars off of ebay instead of ending up with the hole assortment and might never use the rest.

what scale do I use for the complete down load am using 5th Generation Replicator
please help (8/7/2016)
[email protected]

scaling already done. I just downloaded and printed.

How's that LS engine coming along? Can't wait to see it!

Done, just need to do the instructions and parts list.

Awesome work!

i am having some trouble slicing the valve puck. matter control is not generating it completely and cura is even worse at it. can someone send me a working gcode for it?
how can i fix the valve puck so it will actually generate the tool path properly?

If you're still having trouble you can change your nozzle diameter in your slicing software to 0.35mm and Shell thickness to 0.7mm or walls to 2, you may also need to change your first layer thickness down to 0.2 if it is higher just to make the software not throw an error (I'm on CURA 14.12). The difference should be small enough that you can get away with lying to the printer and the slicing software should generate a good tool path. Reason being that actual section of the piece is very near to the nozzle diameter and can generate bad Gcode because the machine may think it is to small to print and will miss pieces of it. Hope this helps!

i was able to print all the part of the engine. now just to find a place to get all the rest of the none printable parts in south africa

xbeerd - in reply to pieterPret

i had this problem and the thing that solved it for me was getting a new quality microSD card. you an view the file and paths in repetier host to check too

i am also using a wanhao di3

i now have probably all of the mechanical pieces printed. i still need to print the intake manifold then I'm done printing. i'll probably miss a few tensioners. i'll print those when i get there

You may need to change your nozzle size since the walls are so thin. My nozzle was .4mm

my printer came with a .4mm nozzle so its default for all my prints.

wanhao duplicator i3

I would play with the nozzle size setting and then try and slice it. I use cure and it has no problems.

im having the same issue. It wont print the walls just the base. .4mm as well.

i had to use slicer to properly generate the gcode for the valve pucks with a layer height of 80 microns.
came out real smooth

This is great! Files downloaded and all scaled up x2. Any tips on the hardware list for a double scale model?

Dude Your Amazing! That 22R Was amazing im still printing up parts for it when i have time. You Should Really Do a Honda B18 Engine Next, The Fan Boys Would Go Crazy!!! Hahaha

@ericthepoolboy: Cam_Spacer_6.STL is not scaled and needs to be rotated

Aug 28, 2016 - Modified Aug 28, 2016
DuneEnginesDotCom - in reply to Deim

Agreed- Any chance of getting a new Cam_Spacer_6.STL uploaded? I scaled the file to 35% and did 90 degree x-rotation.

So cool. Since you're looking for next projects... how about a VW Type II engine? :-)

Hey, I was thinking the same thing. I wanted a VW Type I since it's what I have going into an airplane I am working on!

That is beautifull!!!

Super!
J'ai commencé. J'ai fait quelques modifications pour compenser le jeu de certaines pièces. Mais tout est parfait.
J'ai fait le moteur TOYOTA. Je me suis beaucoup amusé.
Serait-il possible d'avoir les fichiers sous SolidWorks?
Merci !
Très bon travail

All I can say is DITTO on the accolades!!!

Wow, great job on this. Any chance you could upload a .stp file of the assembly? Will you be doing a transmission?

Jul 19, 2016 - Modified Jul 19, 2016

Couple of queries :

  • The intake is on back to front - Any plans to add the rest of the air box etc. ?

  • No exhaust ?

  • Spark Plugs & Ignition Coil Pack are missing, what do you use for leads ?

Example : [img]http://subaruidiots.com/wp-content/uploads/2015/09/coil1.jpg[/img]

  • Missing covers for timing belts ?

  • Belt pulleys & alternator ? ( It needs brackets & accessories )

Would love to see a Gearbox to match, great work so far keep at it ... :)

Cheers, Bantum ...

Somebody get this man an LS1! I would love to have a working LS1 model.

LS3 Coming in about a week

Awesome! Can't wait for that one!

I'll be all over that LS3! Awesome work man! Asking too much for a T-56 to go with it one day?! Haha you are the sh*t!

Awesome, looks like I need to buy more filament in preparation!!!

I'm just test printing the piston... Now I know how small it is! You should make a photo of a piston and sd card and put it there because it seems like people think it is gonna be pretty big...

were do you get the nuts and bolts

Depends on your location. I personally buy them from TME.eu. They got all screws, nuts, jam nuts, threded rods, magnets etc very well categorised and you can even choose from black / zink color etc. Buying bolts in common hardware store is allways very expensive.

Amazing. I will print this as soon as the printer comes back from repair. I plan to scale it down though, if possible.

Hi Eric, I had great fun printing the 22RE engine and gearbox. It is one of my best models I made.
Now I am up for the Subaru engine but can you tell me where I can buy the motor gearbox and some more details how to fit it.
Great work and I admire you. I know a but of design work (60 years in the job)

Estimated filament cost pls?

Good cad work.... Insulting engine design. Those things were aweful in anything that weighed more than 1000kg. :P

HAHAH, new this was a Subby engine (that flat 4 you see in Subby's and older Porsches)

LS1 for sure , great work ! Already have the Toyota one working on this one now.

Jul 14, 2016 - Modified Jul 14, 2016

any chance for a 2JZ_GTE and the getrag 6 spd :) ??

nah, we need the rb26dett first.

This is so awesome, ridiculously good job!

you are the man! keep up the good work

I don't see Cam_bearing_cap_2 included. Is it perhaps labeled something else or am I just blind?

I uploaded it. I guess I missed it when I uploaded everything.

Thank you!! I'll post pics of all the pieces once I finish printing them.

Did you ever take those pics?

I'll post some later this afternoon, still trying to round up all the hardware to complete assembly.

I'm always happy when your stuff gets featured, it deserves it.

what an amazing work!!!

Great work. Special request . Please make timing belt also so that i can print it please..

Belt is roughly 775mm long. GT2

good idea :)

Very nice!
Do you have a clean oil pan without the holes for electronics?
And what length is the timing belt?
Did you 3D scan the parts or you measure and draw everything?

Uploaded the oil pan without electronics. Everything was measured and modeled in solidworks

Thanks! :)
I never worked with solidworks but seems like ton of work in very short time (as i see in lower coment). I might look on that program one day.

Very impressive. How long did it take you to design this? did you design it from scratch?

Everything from scratch. Probaby about two weeks working on it part time. Maybe 40 hours of modeling. I don't really keep track though.

Great work! Congratulations!

I think an SR20DET, RB25DET or a 2JZ would be really cool. Also nice work!

I don't know if anyone has made a special request, but here goes mine:

I have built, for my plane, a bored out VW Type 1 Motor. I have a stock case and reworked crank to carry a prop hub, but otherwise it has been bored out for 94mm cylinders. Could you, would you do something like what you see at greatplainsas.com? Thanks.

There are two kinds of camshaft bearing caps. I found only one STL file, the big one that goes on the front of the cylinder heads and not the small ones. Thanks for the pictures of the gearmotor and speed controller.

They are both there now.

Jul 10, 2016 - Modified Jul 10, 2016

EricthePoolBoy, I think you forgot the STL files for camshaft bearing caps.

Uploaded it. also uploaded a picture of the speed controller that goes in the oil pan.

Jul 10, 2016 - Modified Jul 10, 2016

Thanks Eric. I did the other engine at half scale again and it looked great. I am doing this one at 0.6 of your scale and it looks great - I'm about half way. Pics soon. Thank you. Bathing in Nail polish remover also.

the size in which they have built it?

I want to Build Everything in 50% Scale because 100% is Too big for my Printer

Hi Eric,
What a new awesome printjob !!!
Many thanks for it.

Can you show details of the E-motor drive ?

Regards

Andre

Awesome work man. This is using 25% infill? Do you know how much it weighs? just trying to gauge how much filament I need..

you'll probably need 2kgs of filament total

Well done on the feature Eric, well deserved. Keep it up

Oh and do you have a list of hardware that I would need? If not that's cool just wondering.

Hey I was wondering if I could print this on a 150x150x150 build area thanks!

oh my god! You are genius!

Can i have a question what kind of slicer did you use? Will cura make it? :) (i would love to buy simplify3d, but its too expensive for me at this moment)

All slicing was done with Cure

THIS IS FREAKIN AWESOME

very great work !
so for the spring (all) do you have a reference or is even the toyota motor ?
thank you

The spring was home made again

hi, thank's for your partage, you do a very good works !!!
i will printed all your models the first engine and gear box is allready printed

thank you

Oh my god,

the next great printjob.....

my local Filament dealer is my best friend......

Thanks a lot for this

sorry for my bad english

wish there was a b18c type r motor whould make a good addition to my collection

Amazing work! I'd kill to have a 2JZ-GTE, any chances of that happening in the future? :D

If I can find the cad files for one or have a blown one provided then maybe

thanks so much for you design
but i can't find magnet sixe can tell for get magnet

Nice, just like the one in my wrx (sans the turbocharger)

great job!

Wow! Impressive.

Intake manifold is on backwards >.<

Looks awesome though, would totally print if I still had my STi..

Reversed Spec-C intake manifold Yo.

Huh, never seen a reversed manifold. For a FMIC I would assume..

tu sei davvero un pazzo scatenato!!! complimenti, bellissimo lavoro!

very impressive, im sure it will be a must of my list of projects to make and get working

Wow, its superb! how much time it took to print and assemble?

I just linked this to the Central NY Subies on Facebook. It's blowing minds right now. :)

In 10 years, when metal 3d printers are affordable, people will be printing REAL 35% scale engines, like this.

Try 2 years - the patents are up on SLS printing and there are already some open source plastic ones out there. The tolerances just need to be tighter for the higher temps that metal needs. Alcoa announced yesterday that it is going into production of SLS powdered nickel, aluminum, and titanium for 3d printing. The sky is the limit!

where can i find the SLS printing files so i can do a dodge hemi engine, this boggles my mind because im looking on how to make one with no success, im jealous honestly. can you please point me in the right direction to make one please? very much appreciated. MakeMeInventor7

Print in dissolvable media, use as a positive to create mold, cast in aluminum. Doable in the backyard over the weekend once print is made.

This is jaw-dropping amazing! :)

Amazing work! How long do you think it took you to reverse engineer it (measuring the original components and CADing it)?

About a week working on it here and there. The longest part is printing and getting the smaller parts to fit.

At 35%, would that make this an EJ14 engine? (Snicker)

Well deserved feature

Outstanding !!
Can't wait for the full 3d printed car. :-)

What kind of electric motor do I need to make the engine run?

Jul 8, 2016 - Modified Jul 10, 2016

This is the one I used. It's available in many different RPMs if you wanted to get a slower one.

https://www.amazon.com/gp/product/B008X10IAA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

There's no photo of the motor that you used and I thought that the motor shown in the link is the one that I need because it has 6mm shaft. What about motor controller? Which one fits inside the oil pan?

Motor: https://www.amazon.com/gp/product/B01G9PWRNM/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A2CW54FAZDWUAQ

Motor Controller: https://www.amazon.com/gp/product/B00DVGGWC0/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=AFHAE9RJVUMB

Did that motor and controller worked?

The motor and controller worked but I had to put the controller outside of the oil pan because the motor was too large.

Great job! I can't wait for a transmission or 4WD transfer case for this model (my PrintrBot isn't big enough to print the Toyota, so all my hopes are on this one :) )

@ericthepoolboy: Eric, it would be absolutely perfect, if you could add a "Color" remark in the printed parts list, so people can print this whole engine color by color. When I was printing the Toyota 22RE I didn't really know which pieces goes together (by color) and had to change back filaments quite a few times (to same color).

Kind regards
P.M.

Mate, I love this design and I hope to print one myself shortly. Can you please tell me the length of the GT2 belt you used. I may be able to source one locally the correct length.

I found out that the crankshaft is too flimsy. I loaded the STL files for the crankshaft parts into 3D Studio Max and made the cranks (the parts with the counterweights) about one mm thicker and the counter-bored holes about 0.5 mm thicker. Also, I had to modify the ends of the rear flange and the crankshaft gear where they join the crankshaft parts so that they join better.

How many pla do you use?

May I suggest M3 35mm screws instead of threaded rods for valve stems? This engine and the Toyota engine are the best model engines that I have printed and built. They looked better than other model engines built from kits like the Visible V8 engine.

Using a SHCS for the valve stem was the first thought but since this engine has four valves per cylinder, the valves are too small to use a screw like the toyota engine did. The threaded rod is not ideal but it was the best and easiest solution that works. The ideal valve would be a piece of smooth 3mm rod threaded on one end for valve retainer and epoxied into the printed valve. Also, since the cams use threaded rod since i wanted to get rid of captive nuts/set screws, it was already on the materials list.

Nice job once again Eric. Keep it up!

OMG this is awesome. Please please please make a BMW S14 engine. If you research it you'll find out it has some awesome significant automotive racing history.

This is absolutely amazing!

you sir are amazing, once again, mind blown by your skills!

1jz/2jz model next?

All I can think of saying is "bowing down"! GREAT JOB!!!!!!!

You subaru drivers, just like my best friend who owns nothing but STIs. You guys wave at each other and love flying around corners at insane speeds.

Please do the AWD trans. Might as well do it since the Toyota came with one. Plus I know the Subaru community would absolutely love it.

Plus one for doing a full Transmission & rear diff ( especially the LSD ) - Great work so far ... :)

I really want to. I just need to find a blown transmission i ca take apart.

If you do a 5mt, which would be perfect for the ej20, you can find blown ones pretty often and fairly cheap. If you are looking for one within the US message me. I might be able to find you one relatively cheap, or at least put you in contact with somebody who can get you one. People practically give away the blown ones. I'd love to help in any way I can.

I haven't looked very hard but I haven't been able to find anything. I was just waiting for my friend, that has a WRX, to blow his transmission. Ha. I'm in the bay area, so if you have any connections or info that would help me acquire a blown one, it would be much appreciated.

Just as an FYI, the 5MT for the WRX/LGT/OBXT are pretty cheap, comparatively speaking. You could contact one of the JDM import companies and see if they would be willing to loan you one for engineering purposes.

Subaru sent me a new 6MT. Just gotta make instructions for it now.

i also have a prusa, my first 3d printer and trying to print this i am getting awful prints, Any chance you can list all your settings? id love to pring this

Layer height .2mm
Shell thickness 1.2mm
Bottom/Top thickness 0.8mm
Fill Density 25%
Print Speed 50 mm/s
Temp 190C
bed 60C
Nozzle .4mm

I've got fill at 8% making a nearly hollow engine block but still looks awesome. any chance to make a propeller gearbox for this? I've seen these engines used in gyroplanes quite interesting use though

Once again great work Eric. How about making the famous godzilla rb26dett engine? Let me know if you are interested. I am able to provide you with detailed pictures, specs, mesurements and everything you need.

Wow, just wow!

Impressive work ! :O

Well, I might be crazy a bit and trust your model a lot, but i will print it in polycarbonate or might try the lost pla aluminium casting as this model is worth it and put it on a real efi to make it run on alcool.
gonna be fun to make all the gaskets on my laser cutter and see how long it will run.
i will post it on my new youtube channel soon(still need to finish the channel teaser first)
if you are curious my new channel is called PoNato Sphere(for Project or News around the orbit) ^-^
Thanks a lot for your awesome models. Also i did not filmed your 22re in acction but it lasted 7 min 23 seconds ^-^ but it actually did not melted but the crankshaft craked ;p
Thanks again and keep up

Work of art! Well done

Yet another amazing design. I looked through the parts list and did not see the timing belt used?
FYI, I had the intent with both this engine and the Toyota to make a set of cams to run on compressed air.
You can do it one of 2 ways. Run the current cams, but 1:1 to the crankshaft rotation making it intake and exhaust every stroke of the piston (2 stroking) or, for better looks, boolean join a rotated cam 180 degrees to make double lobes per journal 180 out.
Intake is still intake, but forcing air in rams the piston down, exhaust valve must open on the upstroke normally compression in a 4 cycle, now the exhaust in an air driven motor. Note, intake pressure is limited by the spring choice for the poppet valves. Stronger springs are higher air pressure that they can resist, but wear and friction on the cam and more force on the timing belt system, pulleys, etc.

Timing belt is a GT2 Belt that i spliced together with super glue for a close loop belt. Plan was to find a closed loop belt that fit the length but they are only available from china so it will take a while to get them.

Your designs are mind blowing. I printed a tiny version of your toyota engine and it amazes everyone I show. Then I pull the valve cover and start taking it apart and they can't believe it.

DUDE! This is so amazing. I have to print this since I have a Subaru. I could probably get you pictures of the transmission.

You made a fucking great job, be proud of it

I want to buy this how much cost it would be?

I can print you one for $800 (US) assembled and running as you see it here. Or $450 for all the printed parts and hardware. You would have to finish the parts and assemble.

Hi
Thank you for your reply

you did a great job I just love it . but the quote is quite high.how much you reduce it?
.I am sure will have much more business in very near future similar to this.at this point I want to have this for automobile 3d print sample,

Thank you

You want it to be printed ? You can buy it from the original maker, or you can ask someone to print this and pay back the matter like me, nothing illegal even if the Attribution is changed ;)

Thank you,how much you paid,here in india very few printers and no body reply me for the quotation.Han help or suggest.

Personnaly i sell things as much as it cost to me so i don't really make benefit even one euro (im in euro zone) but i make people pay what it cost me in electricity and material supply. So this full model can be between 70 to 200 euro, i don't precisly know but it depend on different parameter like the quality detail (heigh of layer) the density (hollow or filled at 100%), and wich plastic is used etc etc ;)
But personnaly just by looking i think it can be around 120 euros of work (electricity+plastic low cost)

Hi

ok, I am ready.how can we proceed further?How much time will it take.please include the shipping cost also,

About the shipping i don't know where is the precise destination, but it can go from 4Euro to 30 euro of shipping depending on the location, plus.
Because i'm the kind of maker that go extremly safe on what i'm making and for who i prefer have further conversation about everything like the transaction and else.
ByTheWay i'm open for further conversation but keep remember that the price i gae is just approximative, it can be less, it can be more depending on the precision of everypart i have to print

Hi

destination is mumbai india,since you have done this before I am sure you can quote the correct price.if any thing is missing from my side let me know.so we can began further.

Thank you

Actually when i delivered this to India I had the luck that someone i knew was going to the nearly same location so i haven't had to pay any transpor and everythings got deliver at the same time BUT, making it cost me time, plastic and i can't afford to make this without a garanty of transaction. IF you want to go further more, please contact me on my personnal mail adresses

Can you share you personal email adresse and skyp ID
