I hope you know what you're getting into. You're going to need a new radiator, custom driveshaft, intercooler, possibly a new intake plenum, custom downpipe and exhaust, custom IC piping, etc.

I'm looking to do either an RB20 or RB25 swap myself. I have the resources (time, money, and experienced help). The 20 has semispherical firing chambers like old Hemi's and a torque curve that hits max torque around 2000 rpm and flatlines it to redline. The 25, though, has an extra .5 liters of displacement and a stronger transmission.
