rb20 to 25

[devil_child]

So I have heard of r32 guys switching to the rb25 by using the 20 transmission, accessories, mounts, and driveshaft with the 25 head, block, and wiring harness. So, shouldnt it be possible in the s chassis? What kind of problems would you be running into?

not much its a straight swap over, but the gearbox wont be happy if the motor makes loads of hp.

RB20 gearboxes are known to be unhappy and KA like anyway. :-/ It is pretty great that you can though gives you more time to save up for an RB20 transmission and custom driveshaft, at leas it would for me.
