I personally think thats a little high. See what he would do without the tb. You can get a brand new intake for 800. Also the port job on that looks like someone sneezed on it with a dremel. The factory finish is still viewable in the runners and the bellmouths were barely touched.
I can tell you from experience on the 102 that the bellmouths have very sharp angles that can be rolled over and smoothed, then the runnerand port need to be opened up to have a smooth flow from the main runner part

If you really want the FAST in that CL ad and the guy says he mimicked Mamo, you should have the guy send pics of the FAST and ask Tony what he thinks. He'll give you an honest opinion. Hope this helps.
ya my port job was approved by tony lol. That one really doesnt look like he did much. Ported runners would look really gray and have sanding marks in them. That still looks like the factory black finish on the plastic
I'd buy a FAST 92 intake used in excellent condition or new, then sell the LS6 intake. The only other thing you need to buy is either a FAST TB adapter #146029-KIT ($44) or CBM tapered adapter #CBM-10708 ($80) which is good for at least a several hp over the FAST adapter, then mount you stock TB to it. IMO, this is still a better option than a FAST 78 or 90 intake manifold. Later when you have the extra cash flow buy a NW 92 TB, and sell the tb adapter and stock TB.

The CBM is tapered(small to larger) so there less air flow turbulence, which means better flow into (and through)the intake manifold.

Yep apparently I did forget that lol. Unless I can find a smoking deal on a 90 mm TB I love the CBM idea! From what Tony was saying the TB is the least restrictive part anyways
