if u had 75-80K wut would u buy R32 or R33? would one would u suguest

It really depends on your preferences, and how practical your thinking is.

I'd personally get an R32 GT-R. If I didn't already have a second car as a backup when the R32 has to be worked on, I'd spend the rest on that.

honestly, i'd buy a z06 vette.
or a mallet vette, or lingenfelter vette.

in regards to the skyline, if you've got the cash, get the r33.. i'm a 32 fan, but they're older (honesty here, and older cars need more maintenance)
but if you're going to redo the car completely, the r32 is lightest, one of the quickest, and i wouldn't feel as bad stripping it down and rebuilding it.
and you'd have more money to do so...

Can't dispute that, take a look at my aliases @ cardomain :-)

But for the skylines, I'd get an R34GTR for that price. just live in japan with the extra money :-)
But state side, I'd get an R32 GTR and keep the extra money for parts because you're going to need em. and I'd also keep a spare engine ready to drop in.
