Im swapping a rb25 into my 89 s13. I've read the 8 steps to wiring you rb25 into an s13, but that was for a 92 or so 240, is there going to be any color change in wires since mine was a SOHC instead of DOHC? Thanks for any input.

Ouch.

Check out racebread.com. In the files section, there is Skillzilla's write up on how to install an RB20 in a 89-90 S13. Just reference the stuff on the S13 side of the writeup for Zenki S13 colors and you'll be fine.

rb25 wiring is diffrent from the 20's.the wire colours for the most part will be the same, least the major ones are.

Where did you see the write up on the "8 steps to swapping an RB25 into an S13"? I am debating on possibly doing that setup (RB25 into a 1993 DOHC S13 Hatch) and I would like to read that write up. Could you please give me any links that you have on that swap? I am still deciding on if I want to do it, so I am not yet well-read on the swap. Any help you can give would be amazing. Thank you very much.

My sincerest apologies, I wasn't paying much attention, because I was distractred while on the forum, and this is my first time in the RB section. Sorry.
