Hey im new to the forum and just wanted to shout out to all rex owners or drivers. I have a 91 Si with a gen 1 cable B16A and Y1 tranny. So far I've only done intake, 2.25" piping on a custom exhaust, a few minor bolt ons like NGK spark plug wires. The swap was done using Hasport mounts and shift linkage, 98 GSR axles. I'll post some pics when I can but I only have one so far. Let me know what you think. There are only a few hooked up 2nd gen CRXs in Gainesville.

My question is that my ECU was bad...I was running a PR3 on the setup. I originally had a ZC in the car but swapped it out for the B16A. So I'm using the Si harness. I recently ordered a P28 ECU and the Vtec to Non Vtec harness from hasport. I need to know how much wiring is required on the original Si harness because I have heard that it is not a direct plug and play. Thanks to anyone in advance.

Here is my 91 SiR

 

nice car

 

to use that p28 you'll have to convert to obd1. You can search on how to do it. you'll need obd0-obd1 conversion harness, 4 wire o2, obd1 distributor, distributor jumper harness, and obd1 injectors if your gonna take out your resistor box. Go to rywire.com
