Kits include all non printed parts, 500 rpm dc motor, speed controller, power connectors, and DC power supply.

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.
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.
