91 head swap
 

okay, so first of all, i have searched and searched and searched, and still cant find any answers. i want to swap the d15b2 head off my 91 dx, for a d16z6 or y8 from an SI. the major problem i'm thinking about, is the intake manifold is completely different on my car then on the si. different injectors etc. Can anyone give me an help at all, or has any one seen a thread anywhere that would help me acheive this? thanks guys!

i mean would i just need to get a complete si wiring harness? with all a fuel rail and everything like that?

Well get the mathcing intake manifold for the head and you will need the heads ecu as well as either making your harness work or getting another harness matching the head. You can always look at rywire too they might be able to help you out with the harness.

rywire? what is that, i have never heard of it before?
