except for running the plumbing, The engine is a "bolt on" with a Kennedy engineering adapter plate. I've talked to them about putting the 2.5L NA motor in my 912. but the 912 started running better (a little tuning, and too much oil were the culprits of rough running)...I can give you prices and thoughts...
what are you putting it in??
If you want to talk about this more, write me at

Be careful. this motor has the air to water intercooler. the EJ20T you want is the one with the air to air intercooler. this one might not necessarily have the 220 advertised HP. Besides there is no EJ20DET...that's nissan infection...it SR20DET...in subarus it's only EJ20t or EJ20TT (the twin turbo mill came in 'special' legacys.)
