IM DOING A SWAP FOR ONE OF MY COUSIN. I DONE MANY SWAPS BEFORE WITH DX AND SI HATCHBACK BUT NEVER A 92 CX HATCHBACK TO 92 SI MOTOR. WHAT ARE THE DIFFERENCES? AND WHAT ARE THE COMPLICATIONS THAT MANY OF YOU GUYS HAS RUN INTO. MANY OF THE CONFIGURATIONS ARE SIMILAR. BUT ONE THING THAT IM WORRING ABOUT IS WIRING. SO IF ANYONE HAS ANY IDEA PLEASE HELP. THANKS.

 

First, don't post in all caps, its damn annoying. Secondly, the 92-5 Si will bolt up and all the wiring is the same except for the O2 sensor, and the VTEC accessories. The Si/EX ECU uses a 4 wire O2, where the CX comes with a single wire O2.

 

Just bolt that bieotch in...
