Re:What ECU to use after Swap?
 

Use the teg ecu, but uses the pm6 if you plan on ghettodyning since the pg7 can't be used for that. It may be just a pm6 now but just think what can be done a 90hp civic. Ghettodyne will show you the light(with an eprom burner)and more cash in your wallet in the long run.

Re:What ECU to use after Swap?
 

some1 correct me if im wrong. But I dont think you can use the z6 intake mani. It has different sensors. you need to use the a6 manifold, a6 dizzy a6 ecu and z6 head.

alot of ppl prefer the y8 head because the a6 dizzy doesnt fit right on a z6 but bolts perfectly to a y8

Re:What ECU to use after Swap?
 

That was my original question and I was told I could, that everything would fit, sensors etc., I dont's really have the a6 intake, a friend of mine has it and I was planning on buying it from him, but since the z6 looks bigger I wanted to use that one, and of course i have that one in my garage, I was told I could. If not I want to know before my friend sells it to someone else.
This is what I need If I understand everything right.
Distributor 88-91 Civic Crx Si/EX
ECU 88-89 Integra PG7, 90-91 Integra PR4, or 88-91 Civic Crx Si/EX PM6
Resistor Box 88-91 Civic Crx Si/EX, 90-91 Integra. Any others?
Intake Manifold??? Either 88-91 Civic Crx Si/EX or if Possible stock Z6 manifold if all sensors/plugs fit.

Am I right??
Thanks again for all your help.

i dont think the 90 91 teg ecu would work, its a bseries ecu and i think its got different sensors it looks for. the 88-89 teg uses a d16a1, like a DOHC ZC and will plug right in.

You can also look for accord resistor boxes from the same years as the civics and integras. The integra ecus will work as long as it's not obd1. the pr4 are cool to use. I've even heard some people using the obd0 dohc vtec ecus on there zc's. And for the mani ?'s the z6 or even the y8 will work on any d series head. Just look out for the auto mani's cause some are a little different. The only thing you may have to do is extend some sensor wires but everything is a complete swapover. Also using the later mani's, if you use the throttle bodies, the map sensors are all located on them so no need for the one on the fire wall along with the other valves. One last thing is the newer mani's only less vacuum ports and may have to "t" some lines.

Re:What ECU to use after Swap?
 

Is the distributor on the hf the same as the Si? There's a guy on Ebay saying they are. Just want to make sure because I saw an hf at a Junkyard close to my job. Maybe I can pull the distributor and resistor box out of that one.
