Difference in Rb20/25 wiring harness, motor/trans mounts

[240240]

Question is just as the title reads.What is the difference in the wiring between rb20 to 25 and the differences in the mount kits..

Im thinking about selling my 20 and gettin a 25

why?20 not make enough power?cant stand to rev a motor?wiring is drasicaly diffrent, i hear mounts depending on make can be used on diffrent motors.

Wrong. When I was looking at the schematics/diagrams, the 25 and 20 are pretty much the same. You might have to move a couple of wirea around on the F3 plug but not many. It is very close.

except there is no f3 plug, not like your thinkin anyways. if you wired your rb20 you can do the rb25. you cant take your rb20 harness and use it on the rb25 though.

RB20 and RB25 are totally different its closer to the RB26 then the 25. Wiring is completely different as are the mounts.....

Thanks for the input guys. I will really have to think about what I want to do.

well. the wires go to the same places more or less its just the rb25 runs them trhough the f3 where as the rb doesn't. I have never wired up a rb20 but when I did my rb25 I checked it against a rb20 wiring guide and it was almost the same.
