what is the easiest way to put the sohc vtec motor in a 90 crx hf and have vtec and ac...should i convert to odb1 or can i rig up something with the odb0. and does anyone know if the hf tranny will fit on a 95 ex sohc vtec swap?

 

you can stay obd0 since its already an hf all you will have to do is find a way to hook up vtec (ex.vafc,msd switch)and yes you can use the hf tranny but I would look around for a dx or si

 

I'd run obd1. You will need to buy an ecu jumper harness to run the ecu and rewire the distributor plug for an obd1 distributor.

 

the easiest way would be to use the stock pre obd wiring
just need a Si map senser,then find a PM7 88-89 INTEGRA ECU
Or you can use the si ecu ....all the ac parts bolt right up ....
the Hf tranny blows! I would find a DX trans......or si

 

HELP me out then because we have been workin on my friends hatch for like 4 weeks we put a running 93 ex motor,with the crx si dizzy,and intakemanafold,and wire harness in it and i wouldent start all we could get it to do was turn over,so then we put a obd1 harness and used the ex ecu,intakemany,dizzy,and harness
still dont start gets gas and spark and timeing is right.....Help
what is it...

 

dude hf trannys gears are long as shit..

 

i was just going to put the hf tranny on untill i get an si or something

 

Yo,

I just did this same swap like a month ago complete obd1 conversation as well.

Let me know if you need any help.

shit do it the right way buy the Vtec pwo ecu,and distibutor And run the Vtec wires and everything DO it right dont do no shit job and try and use the Si ecu then you need a vtec controller or vtec will never kick in and you will get Ecu codes out the assJust change everything over you DO HAVE PRE-odb injectors in there right?

 

elabrate on that a lil more rangcrx...and which ecu is the pw0
