Turbo size / cubic inch? Been reading this site for quite a while, just haven't posted much. I've have my '02 LS1 (stock cubes) sitting on the crossmember of my '91 300ZX slicktop, and to keep with the twin-turbo history it's the course I decided to go. I've been reasearching and came to a few conclusions but here's my question:
If my goal is ~500 crank horsepower (with room for a little growth over time), what turbos will provide the quickest spool?
I've been told two things on various forums thus far:
Turbo from an 86-87 Intercooled GN
and
T04e 50-trim
Can anyone else provide me with any more options? I've got the fuel, routing, and management settled, just not sure on turbo model/sizes.

If you only want 500hp at the crank, a twin turbo setup would probably not be in your best interest as far as "bang for the buck" goes. However, I have also been told that a pair of the GN turbos are suitable for an LS1.

Okay, now my cheaper option is reputable!
Any other input is more than welcome.

That's what I've been hearing, that those turbos have a lot of potential on these blocks.

GN=???
GN=???That's the route I've decided on going. On the Buick V6 I've seen the turbo crank out ~350hp as a single unit with ~22psi, but I'm going to run that high until the motor requires a rebuild and I replace the bottom end.
Nice to see you from 3ZC.com
