ok ok my sourse is obviously wrong but i do know that when u do a rb20 to rb25 SWAP and u keep ur rb20 harness there is an adjustment that has to be made on the ignitor chip anyone has any clue what i am takin about

[Joe]

why not just use a 25 harness?

your also going to have to wire VTC in because the 20 doesnt have it.
