I am buying an obd1 GSR b18c1 and am planning on rebuilding it and swapping it into my '96 RS obd2a teg.

Any huge problems im going to run into here? I know all the mounts are the same, I most likely will use my RS tranny because the GSR one with it is on its way out. The GSR comes with the ECU so Ive got that.

Any issues with using my obd2a harness on the obd1 b18c? Ill have to buy a obd2a to obd1 conversion harness to plug in the ECU.

Any help anyone has would be greatly appreciated. Ive been looking around on here for quite awhile, as well as on other teg forums, and google. Thanks for any help.

 

If you run the obd2 harness you will need a obd2 alternator, distributor and fuel injectors.

 

Really? I didnt think id have to...

could i use my alt., dizzy, and injectors off my b18b?

 

You could just rewire the plugs I would assume. Put plugs from a OBD1 car onto your OBD2 harness.

 

Yes you have to since the plugs are different. The alternator and injectors are an easy rewire. But not the distributor. The obd1 harness has two plugs for the dizzy. Obd2's only have one.

People have used the ls dizzy on the gsr but I would recommend the correct one.

And yes you can use your injectors and alternator off your ls.

 

Are b18b and b18c injectors the same cc's? Im guessing they are?

 

All b series are the same. 240cc's

 

Thats what I figured, thanks.

I guess im probably not gonna buy this motor anymore. It sounds like it'd be a little harder of a swap than I originally expected. Im probably just gonna find a obd2a b18c.

 

If you can find an obd2 swap it would be an easier process.

 

Thanks a lot for the help anyways. Good to know for future reference, or for anybody else wondering.

 

I thought oil pump needed to be changed due to sensor. He has obd1, obd2 harness shud have plug for sensor right?

 

If he runs the obd2 harness then yes he will need an obd2 oil pump due to the CKF sensor located in the oil pump for obd2 motors. But if he runs an obd1 ecu then there is no need for it. If obd2 then yes you will need it or it will throw a CEL.
