ok so i have a 2000 sh lude with a bad motor. i am in the process of rebuilding a 97 base h22 motor and planning on swaping it into the sh. the base motor originally came out of a eg civic of mine but i never had the time to get it running. as far as i know the base motor has an obd1 dizzy and i have a chipped p28 ecu i am planning to use. Im going to be using the engine harness off of the sh and using it on the base engine. i also noticed that there is a resistor box for the injectors in the civic. im planning on buying a obd2 to obd1 jumper harness to use with the p28 ecu. Ive read alot about this subject but i am alittle confussed still. can anyone help me with some steps i can follow for doing this swap like what kind of wiring changes i have to make? thank you!

 

The base motor will not bolt on to SH tranny. so unless u have a base tranny and base axles and intermediate shaft to swap on to your SH, then the swap wil not work.

 

yea soory i forgot to mention that i do have a base tranny and axles

 

you'll need the resistor box with obdI injectors

 

this thread may also be helpful. there is a lot of useful info in the prelude FAQ

^ ok will i have to change the injector clips on my engine harness?

 

haven't found any info on the clips... i was thinking that thread i offered was exactly what you were doing, but i missed the part about you using a p28.. + +honda tech = haha.. sorry.. but there is a lot of good info.. another that may help https://honda-tech.com/zerothread?id=2226177

 

Someone correct me if I'm wrong, but you may to do some modifying to the '00 engine harness as I believe the '97 and '00 wiring is a little different; I'd have to go check my Helm's ETM, but I believe there were some small changes. If you have the harness for the '97, you may have better luck with it. I don't know, I might be totally whack on this, but just something to consider.

 

you think i should run the motor obd1 or just get a different ecu and run it obd2?
