If you have the time and money and your car is clean enough, the go for it.

Doubt it'll fit with lots of cutting n custom work. So like Hoover said. Money to blow.

If you can pull it off properly that'd be awesome. Make sure you start a thread for the build! What do you have in mind exactly? Big turbo or just better powerband?

woops, thought you where talking about TT'ing your z32. IMO, a nice set of BB turbo's with the 2.5" I/C pipe/inlet mods and the 3" expansion downpipes and you will have little to no turbo lag. (assuming you don't have huge *** turbos)

I'm still researching every aspect of the idea, and i'm not sure if i'll do it, but i was thinking of having a big turbo with a smaller supercharger.

Isn't that "sequential turbocharging" ?

So you have a Z32TT (VG30DETT) TWIN TURBO right now... and you want to do what with it? Bigger TWIN turbos, or SEQUENTIAL turbos?

I think he means sequential, so four turbos. There is no room now, so I don't no where he would put them. But it sounds AWESOME!!!!!!!

Ah... I misread the part about using a supercharger.

He wants turbocharger + supercharger (the actual meaning of "twincharging"... though the word is misleading since there is no "twin").

Compound turbo it. That's how you blow money properly.

Hmm Nismo's accidental idea of sequential turbocharging might actually be a better route. If properly done it should run just as well, be slightly less difficult (still borderline crazy though), and run a cooler than twincharging. I read that superchargers run less efficiently than turbos, and since inefficiencies get multiplied, it could mean the difference between melting stuff and not.

well, from what i understand when u twin charge, the turbocharger cancels the flaws of the supercharger and the supercharger cancels the flaws of the turbocharger.

Nope, because the blower is still pulling power from the motor whenever it's moving. Also if it doesn't move it creates and air restriction.

A single small blower is sucking about 50-70WHP.

A nice proportioned TT setup will be loads better then a compound blower/turbo setup.
