I highly doubt that many of the plugs will fit. So id say the answer is no.

NVCS wont work (which is nice to have) Ign Chip plugs wont fit.
Dont be a cheap ass, Spend the extra bucks and get a harness

If you got an RB26, theyre more similar with RB20 wiring than RB25 wiring from what I've been told.

Yes the Rb26 is like repinning injector wiring at the ecu or something long that if i recall.
