Hey everyone, im not to sure what to do, I have a 95 ls integra and want to swap a 98 b18c1 engine into it. Im not to sure what ecu i should get for it, i know the 98's are obd2 and my 95 integra is obd1. should i get a p72 obd2 ecu then just get a wiring convertion kit. any ideas and help you have would be greatly appreciated, Thanks

 

No. There are no wiring changes. You should rewire your home computer so that it can access google search, though.

Use your OBD1 injectors and distributor. Plug in your wiring harness. Plug in your ECU.

Enjoy.

 

just fine a obd1 p72 as for VTEC... rywire sells a "VTEC wiring kit" just swap over your obd1 injectors grab a obd2 to obd1 dizzy harness(rywire) and for the alt use your old one with the round plug. the rest is plug n play.

 

Ah. I must have missed the part about him having a LS.

VTEC, IAB, and knock can be wired in via a subharness. Pin the subharness into your ECU plugs. Plug in a OBD1 P72 ECU.

 

Alright thanks a lot

 

-wire in VTEC, knock and IAB
-reuse your alternator and injectors
-you'll need a conversion harness to use the distributor
-if your engine is not JDM you'll have some extra sensors you don't need, Evap purge on the intake manifold and the CKF by the crank pulley
