Alright I have an 88 civic hb base with a d15b1 and **** dpfi. I know someone who has a 90 crx si with a blown engine. Im gonna buy the intake manifold and bracket, injectors, resistor box, throttlebody, distributor, ecu, and wiring harness to do the swap. What ecu do you use in the swap because it does not say in any of the FAQs or searches? Id guess that you use the si ecu because why else would you get it but i just want to make sure.

 

PM6,Pr4,or PS9 ecu (if staying OBD0) And just modify the DX engine harness,(easily done,run a few extra wires),unless ya feel like swapping entire cabin harness out for the entire si wiring.You CANNOT JUST USE THE Si Engine Harness!!! Search mpfi swap...

 

AlrIght thanks

 

Big Z FTW!

 

np,you WILL need the dizzy + injector plugs from the si harness for the dpfi 2 mpfi swap. (or dizzy plugs from 89 ish integra same,and any OBD0 injector harness/plugs)

 

Alright cool I should be set then I'll let you know how it goes

 

would someone that has a dpfi to mpfi harness like to sell it i need one for my zc in a crx swap
