Please bear with me and im sorry if i posted this in the wrong area, but i wasnt sure where to post it...

So i currently have a B18b long block and a complete swapable B18a...the B18a is obd1 and the B18b is obd2...

here's my question:

Can i transfer all of the accessory parts (intake manifold, headers, starter, alternator, etc.) from the B18a and put them all on the B18b and just use an obd1 harness? What i mean is will it run with no issues? Everything is stamped p75 so i figured it should...but im still not sure. And i was wondering which ecu i should use...i have an obd1 p75 LS ecu and an obd2a p75 LS ecu...but its going into my obd2a EK...

Any help and comments are greatly appreciated! Thanks!

 

You will need to use an obd2a EK harness & modify it for your Bseries engine.

If you can interchange the alternator bracket, alternator, injectors, header etc.

 

since you have a obd2a harness everything on the b18b should work, no needing to swap parts unless any parts are missing. if thats the case, whats missing?
