I want to know of there's a difference between the d15a2 and d15a3 blocks? Like can I grab the a3 head (complete w/ everything), wiring harnesses, ecu and fuel pump, swap them all put and call it good and try to start?

86 Civic DX HB, trying to convert to fuel injection.

they will bolt up but there is a diff. the pistions are diff and crank. so you will have to check your deck height.
also the a3 has the oil cooler on the back the a2 dos not.
