R32 Tech Questions

[iplen]

I have a few questions about R32 GTRs, these will all seem a bit odd but there is a reason...

What size is the inlet on the stock turbos?

What sort of weight does one come down too without the interior and all the comfort crap?

are there many weaknesses in the suspension? eg arms etc

would 15 inch wheels fit over the brakes?

roughly what sort of drop in revs is there between gears in a standard box?

thanks in advance, yes I may sound like an idiot, but it is well founded (that I am an idiot)
