I've just done the 63 swap in my 4WD cyborg. Goes really hard. No mods yet apart from k&N. pushing about 160-170hp at the wheels.
I got the EVO 0 engine which has yellow 510cc injectors and a 16g turbo.
Gearbox seems to be holding up well.
Can get some good drift if you want to put the power down around the corners.
Spins all fours in the rain with a quick snap of the right foot.
