ls6 intake 90mm Aloha gang,
How does the ls6 90mm snout with tpis 90mm tbody compair to the other intake combos out there.
Right now I'm making 426whp, with the stock 85mm MAF, no screen, homeported stock 75mm tbody ls6 intake, 235/245. 630. 113 lsa cam and headers thru straight exhaust( true duals) stock ls1 heads

Or instead of paying for a 92 and then paying to get it ported, you can get the fast 102 and use the 90mm TB and spend less on the parts you need for it than porting the 92.

A (new black) FAST 92/90-92, or if your budget permits as FAST 102/102, I've got a TPIS 90/90 and beside the weight difference from my previous BBK ssi/85 I really didn't notice much difference except maybe a little better pull in the very top end (5800-6500); so get the FAST intake!
Or......you can buy my TPIS 90....?

Always seems to come back to the FAST. I don't want to grind down areas of the 102 to make it fit under the hood. Maybe I'll go with the fast 92/92. I forgot to mention my redline is 7000rpms. So i push my clutch and shift at 6700 when racing.

i am no air flow expert but there are more than a few very knowledgable people in the industry that are of the impression that the 102 runners are less than stellar. if you aren't on the "latest and greatest" band wagon and look at the amount of people with drivability issues or simply less than stellar results with the 102 it tends to make sense. there was a reason that the 90's and 92's were commanding such big money used. I'm sure FAST didn't bring the 92 back for the hell of it

Anyway, I would love to see a comparison if anyone has any info. Now that the 92 is back on the market, I'm torn between the two.

I'm no expert either, but I'm pretty sure they were commanding a high price because they were not being made anymore. Now they sell for just about the same as the 102s.

The 102 runners are more optimized with improved radius'ed entries, a more desirable shape and cross sectional area thru the entire port (it is taller creating problems for Vettes). The outlet of the manifold is also much less compromised than the 92 in terms of shape and airflow . Its a new design unlike the 78-92s with removable runners that sit in the new base with an O ring seal around each port. The 102 also features a much more rugged body which is about 3 pounds heavier. The inner seal problems with the older manifolds is no longer a problem. People that have extensive porting experience with both say ported the 102 has more potential. However if you have an electric water pump you may have to grind it to fit with a bigger than 92MM TB(or buy a new LS2 pump). Fat injectors like SVOs shouldn't be used. You need a new fuel rail kit amd adapter kits depending on injectors you want to use. If you use a 102 TB tuning can be a challenge in terms of driveability. If you want the best despite the challenge and cost the 102 is what you want.

They sold for such big money because they weren't being made anymore and people were under the impression that a 102 is "too big for a stock cube motor."
If it was so much better, why did they make a new intake (102) and discontinue the 92? herp derp I'm sure Wilson/FAST has flow benches and enough data from R&D to make a decision on which is better. They would have kept both intakes if they had a reason. They didn't because the 102 was an improvement.
They brought it back because of what I explained previously about the 102 being too much and people not understanding how the intake works on a direct port fuel injected vehicle.
The price has been dropping on used 92's since the new one came out.

Basically equvlient to a stock unported FAST 90, I have one and like it . I felt a big difference over a ported LS2. Made 420/400 on a Dynoite with 226 cam and PRC 2.5's.

No. Even an unported 90 will out shine a 90 mm ls6. People fail to realize, The tb opening has little to no effect on power. The runners and plenum of the ls6 is what holds it back compared to The fast intakes.
The ls6 intake was designed to work with the ls6 cam. Any cam that carries power above and beyond the ls6 cam will be choked on The top end. Regardless of how big the tb opening is on The ls6 intake.

Well I think Mike here summarized this best. The only thing the 92mm will do for you is let you use your stock fuel rails and stock water pump.
