Default FAST Intake
I have a deal on a fast 90 intake and I think I remember a forum saying there may be trimming involved to fit? I can't find that thread again but does anything need to be done to fit that intake? I have a stock throttle body if that plays a factor

What year motor/car are you putting it on?
I believe 90's were all for cathedral ports heads.

If you look at a new FAST the back is lower than the front. Early ones required cutting the cowl up. I did a forum search but I could not find it. Below is an article I find using google.

Here's the thread. You can cut the FAST and put in a patch instead of cutting the car if you like. But don't use plastic, it will melt and you will have a huge vacuum leak. My buddy fashioned a sheetmetal patch for me and glued it in with epoxy 5 years ago and it's been fine ever since.

Interesting Joe, I just installed a FAST yesterday on my 05 C6 and the back of the manifold is really tight on the back of the cowl/firewall.

FAST 92 or FAST 90? The 92 was modded when it came out to fit the C6.

Either FAST is a GREAT mod for the ls1, 6 or 2. Particularly the LS2, you did well installing one.
