VR-4 and N/A Motors

I was just wondering what the differences are between a 3000GT VR-4 and and N/A motors. (Besides twin turbo)

Are there any?

RE: VR-4 and N/A Motors

The TT blocks do have some extra oil squirters I think. Exactly where they are and what they do is a bit of a mystery to me. At some point, the TT's got forged internals (crank, rods, pistons) the NA's didn't. The cams on the NA are actually a little more aggressive than that of the TT's. I'm too lazy tonight to look up the lift and duration numbers.
They are the same, dimensionally speaking, parts are interchangeable.
