How many are running this setup? What all will I need to finish the job? Any problems? And what's the HP gain going fast 92 over ls6 on an ls6 engine?

Keep in mind your gains won't be as large if you have stock heads/cam.

What else is done to the car? You won't see too much gain on a stock engine. There are better ways to spend your money if your car is mostly stock.

Just LT's and high flow cats right now. With the fast 92 and 90mm throttle body I plan to add a vararam ram air intake, and than get a tune. Just want to do bolt-ons. Not going to touch the inside of anything for a long time if ever. Want the car to be a fast bolt-on car.

I gained 18rwhp and 12ft/lbs with heads and a cam. It also improved the power curve, allowing the HP to carry through to the 6850rpm rev limiter with no drop off.

I'd just be happy to pick up a little over a mph in the 1/4 mile with it. Wich I think it will do

Setup runs great

I would certainly get it ported before slapping it on, but there's nothing wrong with them AFAIK.

skyavonee - awesome link!

I have also been considering doing an intake swap. what kind of gains can you expect with a came only LS6 engine with full exhaust?

Also one thing I might add, now (while swapping intakes) would be a PERFECT time to install an oil pressure sender relocation kit!

Toque deserves the thanks, not me!
