I just traded my project MR2 for a 98 GSR motor. I plan to swap this into my 1990 CRX Si. I have searched the internet for days on a write up for doing this. It doesn't seem to be too popular. I am assuming because of the cost of the motor. The motor part will be easy as I have done plenty of swaps. I am not too sure on the wiring portion and running OBD1 on a OBD2 engine.

Here is what I have so far. I am currently running a D15b2/D16z6 mini me. The harness is already wired for GSR plugs thanks to the previous owner so I'm thinking I will just need to cut the plugs off the GSR harness and use them on my current set up.

Parts list:
B18C1 Engine Complete + Tranny + Harness uncut.

98 GSR ECU ( Assuming the motor is a 98 also. Have not looked at head stamp yet)

GSR Dizzy OBD2 from the looks

Integra axles. Came with motor.

Innovative EF to B series motor mounts

Innovative hydro tranny conversion kit + shift linkage

DX throttle cable. I think this will work it's pretty long.

Still need an intake. My single cam one will likely not work.

Chip kit and P28 ECU.

Since it would be stupid to convert from OBD1 to OBD2 I am hoping that my D16Z6 Dizzy will work in the GSR head. I have read that it does but have no confirmation on that. Also, I don't know if 98 Integra axles will fit 90 Si hubs. Other than wiring those dumb secondary butterfly valves for the intake manifold am I missing anything? I should be able to tune out the knock sensor and secondary o2 sensor.

I also wanted to get this bar'd but a friend of mine said that even if I converted to OBD2 I still would not be able to. Confirmation on this? If it's possible I'll convert to OBD2, get it bar'd, then go back to OBD1 and use my chipped P28 for my nitrous kit.

Any write ups, guides, or information from anyone that has does this swap would be greatly appreciated.

Thanks! (Prepared to be flamed)
