I have a OBD-1 B16A SiRII and am running an OBD-1 PR3 ecu.

I was wondering if I switched to a p30, what is supposed to be with that engine if I would have any power gains?

 

the pr3 is meant for that motor as well. they should run the same

 

i know for sure my obd0 pr3 and obd1 p30 ran alot different the p30 was much stronger.
idk about an obd1 pr3 though. if you already have a p30 try it out but if not, it should be THAT much of a difference that you would want to buy one.
