I just want to run my swap through you guys to make sure the wiring will go right and to listen to any of your suggestions before i get started. I am doing a swap in my 89 hf crx with a b18c with a y1 tranny. the injectors and distributors are from a b16. the ecu im using is a pr3. is this going to wire up easily with a hasport wiring harness? Thank i also have a dc 4-2-1 header should i wait until it is installed or is it easier to put the headers on before i put the engine in? tahnks for your help.

 

if your b18c is from an SiR or SiR-G Integra (equivalent to our b18c1 gs-r motor) then your PR3 ecu will not control the secondary runners of the intake manifold. if your b18c is an R motor then you'll be straight, but you'll need a pre-obd (obd0) distributor.

 

its a gsr motor and i have ob0 distributor and i replaced the intake with a skunk2. were can i get info out how to wire it up ex: wieing harness how to conveert the grey pulgs to wire up with my hfcrx?

 

the PR3 ecu will not control the secondary butterflies.

 

Here is what I did.

I am doing a SIR II swap OBD1.
My car is a 91 DX ƒ¼

I had a homeboi convert the ECU harness TO OBD1 and the Engine Harness TO OBD1 that way its easy plug and play. Well the route you going I don't know much about so I can¡¦t help you out any more. If you run the OBD1 it will be much better.. PR3 OBD0 does not have all the sensors you will have problems engine check lights the GSR has two butterflies.. If someone can do a conversion for you that would be great ask around!!!

I am new here so take it on easy I just got in the swap business and I am learning so please take it easy on me if I sound wrong
