I'm sure that's a common practice around here.
There's lots of info online for these swaps too
As for being easy I don't know how handy a job it is but I'm sure someone on here will help ya best of luck with it

engine and box will bolt stright in you will need a custom prop, loom and ecu and all rb25 sensors then a bit of wiring done i have both pin outs for spec1 and spec2 r33 gtst let me no if u need them

Yeah...Mostly all bolt in...then your loom has to be spliced and re wired...
Simple when you know how...

Just to butt in, what are the pros and cons of the 25 over the 20??

And a custom prop is needed?


Can a power fc for a 20 be modded for a 25?
