Best Engine Conversion

[FloWolF]

I have basic knowledge of cars and im currently studing Computer Game Programming, but i have always loved the skylines and have recently bought one of my own.

Seeming im still only on my P2 Licence it was a non turbo, but the skyline has now become a hobby of mine and i would like to modify it.

I'm asking the community if any of you would know what they best engine conversion for the skyline (keeping within Nissan Engines) would be?
