F.A.S.T. 90/90 Combo
current mods and numbers in sig. what would the gains be if i go to a FAST 90/90 setup. i'm mainly looking for more TQ. yes a swap to a bigger cam (Torquer v2) is in the near future as well. thanks.

10-15 for both HP and TQ would be my guess.
The LS6 intake does really well for most H/C cars. It is when you go beyond that it can start to be a little restriction.
Also...if you do it, get the FAST 90mm intake and a NW 90mm TB.

perhaps i should go with the cam first and see where i sit power wise. that route is cheaper than the 90/90 setup...
set 90/90 includes a NW t/b...

Okay good.
I got the FAST 90mm TB and read after the fact that people had issues with them. So far so good with 3500-4000 miles on it.

Pretty much like any intake install for the most part.
I made a mistake installing my valley cover though. I knew I had to use the new bolts FAST sends but I didn't anyways....must have been one of the beer drinking working on car afternoons.
Got lucky I didn't crack the intake.
You will need to make sure you get the port gaskets though. Mine didn't come with them. TB gasket as well.

If you have done an intake install before...pretty much the same thing.
Vasoline for the injector o-rings.
Make sure to use the valley cover bolts supplied.
Otherwise...straight forward.
Enjoy!!!
