Hey there, recently I bought my first Skyline, a 1996 R33 with a RB20E in it. It's alright for what I want for now as I am attracted to the idea of an N/A because I am a student. Keeping that in mind, I would like to put something a little more powerful in it aka the RB25DE engine. Just wanting to know how hard it would be to do this swap, what extras would I need other than the engine itself and just some general advice. Cheers
