90mm, Are there choices for intake manifold I have a forged LS6 motor with a TSP 233/239, high compression, and the stock (78?) throttle body on a LS6 intake. If I buy a 90 mm TB (Katech or LG) what are the choices for a manifold. Will a LS7 intake work on my LS6 heads.
What is the best combination of intake and 90mmTB???
Thanks for your ideas and experiences.

Is the LS2 TB 90mm? Has anyone tried LG's 90?
If I buy a FAST 90 intake, do I have to port it? Are the stock ports small??
I ran three races last year and won 2. This year there are a couple of LS7 Vettes out there. I need to step up.

You don't have to get it ported, the stock ports aren't small. Tony Mamo had a post a while back about porting the Fast 90 and its results.

Forget about the ls2 intake. It makes less power than the ls6 intake.
FAST is your best option. If you get the FAST, spend the extra to have it ported, it's worth it, might as well gain as much as you can if you're going through the trouble and money of putting it on.

OK, The FAST is the best intake, or the only intake, stock good, ported better.
Nick Williams TB is good, is the LG throttle brand new, anyone tried it yet.

Going on a C5, Corrrect. The new LG looks good, Katech makes a 90 also. I'm going to buy one of these soon.
My engine never has had really good throttle response, maybe the program is not perfect, but it just seems lazy when you push on the gas until it hits about 4000 at WOT, then it screams. I'm thinking that a 90mm on a FAST will wake it up. That engine has enough compression and cam, and a light flywheel, it should rev fast.
