im not into crx's,i have a 95,my friend is doing a swap into his rex,so i dont have a clue as to which ecu he is suppose to use,what ecu should he use,and what cars can it be found in,can he use a older integra ecu or does it need to be a jdm one?

 

What is he swapping into this CRX?

 

We are really going to need to know what swap he is doing.

 

sorry,really dumb of me,been up all night at work,right now they are still searching for the engine or donner car from a auction,i know they are shooting for a 94 ls,he knows he will have to put in the hydro clutch,what ecu will he need to get,will it work with the injectors and the distrubitor from the 94 ls,thanx alot,sorry again.

 

theres many options
the ecus u can use are
88-89 integra PG7
88-91 civic/crx Si PM6
both of these above for OBDO electronics
if u convert OBD1 then u can use a P28 92-95 civic Si/EX
for a VTEC engine DOHC on a OBDO car u can use
PR3 and PWO off JDM SiR's
or u can use a Zdyne 1 wire conversion for virtually any vtec engien out there

but please when u post a question gives us details
damn

 

If he goes with a 94 LS you have a couple of options. You can convert to OBD1 and use either the 92-93 LS ecu or 94-95 LS ecu. Or you can convert the engine to OBD0 and use the 90-91 LS ecu. You will probably get better performance from converting to OBD1 and using the 94-95 ecu. Secondly I would use either a 90-93 ls tranny or 1st generation B16 tranny. There is no need in trying to convert cable to hydro.

 

As long as we are on this...

I have an '89 CRX with a DOHC ZC with the ZC ECU. I'm curious about using the Integra ECU. What year Integras did these come in and how much should I expect to pay for one?

Most people use the 88-89 teg ecu (PG7) with the zc. They usually run about 75-100. Probably better off with the PM7. I have had both and the only real difference was the PG7 running rich at idle.

 

do they sell a conversion harness to go from a crx harness to a 94 ls ecu?who makes them.i think he is going to use the 94 ls tranny because its going to come with the motor so he will have to convert it over.

 

Check with Blown90Hatch on the OBD0 to OBD1 conversion harness. He will give you all the info you need. As far as the tranny, converting to hydro will really be a pain. You would be a lot better off to sell the hydro tranny and pick up a cable. It that is what he wants to do however, good luck with it.
