F.A.S.T. on a bolt on LS2 Im going to be dropping in a LS2 engine in my 30th Trans Am. The car will have every single bolt on available with out opening the motor. Will I benift from a fast 90 or even a 102 intake since im not running a cam or heads? I have a LS6 intake available with ported tb and an LS2 with NW tb.....Whats you guys think?????
My LS2 GTO with full bolt-ons (minus UDP and RR's), 1 3/4" Kooks LT headers, dual 3" full exhaust, non-ported FAST 92, and a P&P 92mm stock TB made 395/415 to the rear wheels.
The stock LS2 intake would make a better boat anchor, and we all know that plastic floats.

Not worth the cost IMHO unless you are cammed. Hell I only gained another 15 rwh after I installed one on my cammed LS2. I thought I would get more than that. I doubt you would even get that out of stock cubes.
A fast would give u gains, but the ls6 intake flow better than the ls2 intake so you could install the ls6 u have and look into another mod if cost is an issue.

FAST is the only way to go IMO. LS2s are the worst intake ever..... Ive never seen the
FAST make less that 20hp on any LS2 intake vehicle. Ive seen ranges from 20-44hp with just and intake swap.

A Ported FAST might pick up 25 peak, but under the curve mine picked up over 30rwhp/rwtq on my bolton LS2 and I dropped .3 and gained almost 3mph in the 1/4.
