Jizzy boy, you'll need an AWD engine for ease of transfer, but even then you'll have to change the ECU over, possibly some wiring, while you're at it you'll need to upgrade your brakes if you wanna have it engineered... oh and you'll need to get it engineered if you wanna stay legal. Not to mention it'll be an auto, and making it a manual is about the hardest swap you can do cos your choices are "R33 S2/R34 GTR gearbox", or "R32 GTR/GTS4 gearbox plus a lot of messing around".
If I were you just make mad cash moneh by selling it to some P-plater stooge that wants to jump the cool car bandwagon by buying a heavy ass non turbo. The moment you turbo it, it'll drop in value.
In short, DO NOT BUY AN AWD SKYLINE unless its a GTR. Trust me, I own one... and unless you're gonna be happy with it the way it is for as long as you have it, don't buy it.
