Hello, ht I got a 99-00 civic si w/ The b16a motor and a few weeks ago my b16 motor blew on
Me But I'm currently looking at a obd1 b18c1 gsr motor I need to know what I need to do tis swap (turn it to a obd2) I know I will b using the injector, alternator, distrubutor, motor mounts and wiring harness from the b16 is there anything else I need and any stuff to rewire please help me if anyone can. Thanks

 

umm, get an obd2 engine and make everything less of a pain. or just work with what you've got, build a long block and use your stock harness/ecu/etc & get it tuned.

 

doing research with obd1 ls into obd2 this is how it goes:

1. injectors from obd2 can be reused
2. obd2 dizzy wont bolt, plug needs to be repinned, or buy conversion harness
3. crank pressure sensor: you can trick ecu to read it correctly
4. iavc needs to be rewired 2<->3

think that's it...

 

just transfer the engine harness, injectors, dizzy, alt over to the gsr and everything should be plug n play..u will have to add a wire or 2 for the IAB if you are still using the gsr IM..as for the CFK sensor thats on the oil pump u can trick the ecu by splicing some wires together...u should run a obd2a gsr ecu since they dont have the immob.
