So my original 96 b18b1 lost compression but i got a good deal for a 95 b18b1. Im going to stay obd2a and use my old harness and ecu. The 95 is automatic and obd1, my 96 rs is manual and obd2a. Im going to swap over the intake mani, dizzy, and injectors but do i also have to swap over sensors from the block like crank sensor, tps, temp guage, etc…? I also read the 90-95 water pump is different from 96-01 but i doubt i have to swap my 96 water pump to the 95 block since its the block itself, not a harness. Anyways i was just wondering on what i have to swap from my 96 to the 95 b18b1. Any help would be greatly appreciated!

 

The 95 doesn't have the crank sensor on the oil pump that you need for the car to run in a 96.

 

should i just swap everything over from my 96 to the 95 motor?

 

You don't need the crank sensor, you can jump 2 pins at the ECU to bypass this.

 

I believe the 94-95 B18b1 blocks also have a different crankcase ventilation system that is similar to the GSR with the blackbox in the back of the block. You might need to decide whether to block the breather port the blackbox sits and run the 96-01 style with the PCV on the valve cover or run it like the 94-95 cars with the blackbox installed.
