I read the guide here "http://www.angelfire.com/d20/hcivic88/dx-siwiring.html"

What year model Si parts should I be looking for. I would assume 1990, same year as my car, but I just wanted to double check.

Same goes for the Si fuel rail, the intake manifold, and the ECU. (I should just search to buy any ECU that says PM6?)

Appreciate it.

 

you will need harness and yes you will need a pm6 but you can also use any of the single cam d16 ecu if you want tunability then you will want to go to obd1 now with that said i would recommend using a skunk 2 manifold they build good bottom end witch our cars severly lack. With those you can use a stock rail and injectors but you can upgrade those later and you will also need an injector box that a bou covers it have fun

 

the year range doesnt really matter. but if you can get everything from the same car cuz 88 is different then 89-91. figured that out when i did mine lol. you need the complete intake manifol, dizzy, injector box, ecu(pm6), and a harness convertion. good luck with your swap you will feel a huge difference.

 

Ok. I found the MPFI. I can get the harness online no biggy. I can get the distributor from local oriellyauto

the ECU, is this the correct one? (from 1990 si)
