Ported LS6 Intake/TB or Fast 90??
Ported LS6 Intake/TB or Fast 90?? Which would yall recommend? I know I'd end up spending a little more with the Fast 90/90 setup but wondering if it's worth it. So my options are buy a Fast 90 and a 90mm TB, or purchase a used LS6 intake, have it ported along with my TB. Which would produce more power and be better suited for my planned combo? I've got a T-rex coming and still shopping for a set of LS6 S2 heads, probably PP or PRC.
Get a Ported FAST 90. If you are doing both the cam and heads, then the FAST is a must. LS6 will be a bottleneck on H/C. I can't say I'm up to speed on the "Ported LS6 intake", but I'd have to imagine the FAST will still flow better, even an unported FAST.
LS6 intake is a one piece design,,unlike the LS2 intake, or FAST, (3 piece) There really isnt much of any material you could remove on the any of the 9 openings without screwing up a seal is there???
I voted LS6 and ported TB because they made nice power for me. Its the cheap route. If you have money and dont care, get the FAST 90 ported. I wouldnt get a non-ported unit since it'll give you only 7-10rwhp for 1250$...ported will get you 25-35rwhp on full boltons h/c..

I believe New Era Performance ports them but the gain is marginal at best from what I've read. You are better off saving your pennies towards a Mamo Ported FAST 90/90 setup...
There is a big difference between H/C and Forced Induction in the application of a FAST. FI would blow the FAST apart as it's a 3 piece design. Pretty much anyone who is FI has a LS6 or Weiand Metal Intake. A NA engine will benefit from a FAST everytime over a LS6 intake.
I went for NOS instead...
if the hp gains doubles, I think its worth every $$$
