ok i kind of need help here..
i've been having many and many people tell me different anwsers..
what ecu will i have to get to get the ex motor going?
what engine wiring harness should i use?

if you can help me with this i would appreciate it..thank you

-mpf

 

depending on what u do... but regardless... you'll need a p28 ECU or any other single cam vtec ecu (if there are any others). Ur going to either have to change your existing wire harness to OBD1 wiring, get new OBD1 wire harness, or use a jumper harness to the ecu.

 

thanks man..
someone was telling me i can use the OBD0 ecu..is it true?

 

hmm, i think if the obd0 computer supports vtec you could. Actually there might be a way that you could rig the vtec on a computer that doesn't support vtec, i forget....maybe someone else knows?

But in the end, it'd probably be easier just to find a OBD1 p28 and use that?

 

thanks JDMB16ACRX..

my setup is d16 vtec motor, t25 turbo,hf manifold, custom downpipe, magnaflow exhaust system from a integra (90-93)..

 

get yourself the p28...you can splice in the vtec harness into the obd-0 harness and convert to mpfi...you'll need the jumper obd-1 conversion harness....blown90hatch can help you

 

he's doing a mini-me swap..the only concern that we have is what ecu we need.. been hearing lots of different answers from people and getting confused.

 

yeah i guess i'll just get the p28 ecu than..

to make it easy for you go get a 88-91 crx si wiring harness and a 92-95 civic ex ecu it should plug right on

i second that..

 

I went with a ZDYNE one wire conversion when I had a D16Z6 in my 91 CRX Si. They take your 2g Civic / 4g Civic's ECU and convert it for VTEC control, costs around $320. Later on I sent my ECU back in for the GOLD SECU conversion when I added on a JRSC.

NO NO NO NO NO NO NO NO NO.....Please stop giving out incorrect information. First off, not all 88-91 civic/crx engine harnesses are the same. Secondly, the 88-91 Si wiring harness and 92-95 ecu will not plug into each other! They will not work without SERIOUS modifications. DON'T DO IT.

It is fairly easy what you are wanting to do. Here are the parts list:

Your stock engine harness....rewire for MPFI if needed.
OBD1 D15 Vtec motor, OBD1 D15 vtec distributor and ecu....or P28 ecu.
OBD0-1 Conversion Harness - THIS ONE
4 wire O2 sensor if it didn't come with the motor.

All my harnesses come with detailed instructions for an easy installation. I have done the EF to OBD1 conversion so many times I almost have all the ecu pin outs memorized. I am here to help out if needed. I also have stock P28 ecus in stock.
