I have a good d15 out of an eg hatch that has low miles and no problems and ran good in the car it came out of. I want a problem free engine for my 1990 hatch. Would I be able to use the block and head from the d15 out of the EG and use the stock wiring harness from my car, along with the dpfi intake manifold and the distributor from my engine in my 1990 or would I need to do more to make it work?

 

Yes, the only difference between the b2/b7 is the MPFI everything bolts on right.
