Hello everyone, This is my first time writing in this forum. I just had a question about swapping a JDM H22 Obd1 into my Obd 1 H23 prelude. I know that it is a simple swap but I was wondering if I could use my h23 wiring harness and what i would need to do to it to make it work. The motor didnt come with a p13 ecu so I was wondering if I could use my p14 and just add a rpm activated switch. I also hear that I would need to change the jdm fuel rail, is this true? If anybody can help with this I would really appreciate it. Thanks.
