. i read it over and over for two days. Lol! Then decided to go ***** out i used a 90.integra ls pr4 ecu n distributor a 94 civic intake manifold along with obd1 injectors that allowed me to delete the resistor box. I started the swap ahout a month n a half ago. N today of all days i think i got it to wer im happy with the reslts. Except for my 4spd tranny. But. Should be. Changing that this weekend. Hey its actually easier than wat it seems. Just make sure you take your time. Good luck n pm me if you have q's . Ill try n help with wat i can. Also do wum research.

 

no my car is a hf saids in the back and title also..

 

thanks man really this info is very helpful due to the fact that i need my car running asap.. so by getting obd1 injectors and 94 civic intake mani will delete the resistor box? but did you put a whole different swap or just made the single cam mpfi?? does anything change on harnesses llike 88-89 or 90-91 harness like is it plug and play or what do i change?? i picked up a full 88 si harness but my car is 91 hf..??

 

Ok i have a 90 dx hatch when my friend gave it t me it had no mtor. Luckily i had an 88 dx hatch that i couldnt register so i pulled the d15b1 along with the fourspeed n engine harness n threw it in the 90. From what iive been told the harness is difrent between 88-89 and 90-91. So i dont kno how my car is running. Lol! damn ! Im that good ? Well u dont need the si harnesss its easier to modify the harness yu have now. Thas what i did

 

Well my dpfi harness is cut that's why we also swapped harness.. but engine harness is uncut..

 

What ecu can I use? I got a 37820-PR4-L60 AW , 37820-PM6-A09 MK , 37820-PM6-L080 9M ??
