FAST 90 and 102 questions...
#3
I'm not selling, I'm looking to buy. Just wondering if I should bother with the FAST 90/92 since I can pick up a new FAST 102 for less than I've seen ported 90/92 go for. Even unported 90/92's are selling for close to what the 102 costs new...
I've got a FAST 90 throttle body, would it work with the 102?

There was a unported, unpainted 92 that sold on here for 1k!!.....crazy money. You will save a little for fuel rails on a 92, and you have to mess with the TB hitting the water pump if you get a 102 TB. I think a 90/102 will fit, but I have seen pics of the TB gasket hanging out on the bottom
I think Vengeance sells 102's ported for 1k.

its all in how you look at it switching from a ls6 with ported tb to a stock fast 92/92 i picked up almost 4 tenths on the motor with a half tenth worst 60ft time only change was the intake tb and re tuned the ve table for the new intake i bought my fast with a nick williams tb for under a grand so i think it was a worthwhile upgrade

Well I've got an intake restriction on the top end, I'm pulling a vacuum in the higher rpm's. That's with my stock MAF, ported stock throttle body and LS6 manifold.
I've gotten my hands on a FAST 90 throttle body and I'll either get an 85mm MAF or do a speed density tune. The issue is the manifold. Putting a 90mm throttle body on the stock 78mm LS6 intake won't help me at all.
I missed out on an unported FAST 90 intake, paid the guy even, but he'd sold it without telling me. He did refund my cash, but I'm still left looking for another one.
I just feel strange paying brand new FAST 102 money for a used FAST 90.
It's $350 to have a 90mm snout put on my current LS6 manifold. Or I buy an LS2 manifold, fuel rails and injectors, then need to clean up the manifold. Or I try to find a FAST 90/92 intake manifold for a decent price or just get a FAST 102 and use the smaller FAST 90 throttle body I already have with it.
Which option would you guys choose? I'm not thrilled with adding a 90mm snout to my current LS6 manifold because then I can't recoup any money by selling it...

No. Porting is virtually useless on a ls6, unless you mean the 90mm snout conversions, which is helpful but still does not meet the capabilities of a stock Fast intake. A properly ported Fast will be even better still.
But if you mean just someone taking their sanding rolls to the opening and the runners of the ls6 intake...total rip off from the results I've seen posted.

If you can't find a deal on a 92 just buy a new 102 and use your TB. I'd just do a little research on mating the 90mm TB to the 102mm intake. I know people have done it, just not sure how well it fits to the intake snout or if an adaptor is needed.
I just checked E-bay, and there is a guy selling a Mamo ported 92 for $1600!!!

^^ That's nothing. I posted a WTB ad knowing full well that I'd get some crazy ****.... but I had a guy offer to sell me a FAST 92 with a 92 TB for a whopping TWO THOUSAND ******* DOLLARS.
Guys, the only reason prices are what they are is because we pay them. If we quit, the price would go down.
I opted to pick up a FAST 78 for the time being. Runners are identical, and if I REALLY need to, I'll punch it out to an 85. But I doubt it.

just bought a 78 for 500. In the long run, i decided that the 78 was the best choice. You can use a stock ported throttle body and oem fuel rails so there is no need for adapters or fuel rail modifications. The biggest reasons i have seen against the 102 is fitment might require shorter motor mounts, you need expensive fuel rails, you need expensive throttle bodies to get the full 102 and adapters.

I'm not impressed with any of the FAST intakes. I have an LS6 and have raced many cars with similar mods, except they were running a FAST. I've beaten way more FAST equipped cars, than I've lost to. For what they cost I think they're a total waste of money unless you have money to **** away. Dyno numbers are cool to look at with a FAST. But I'd rather have an LS6 car that wins races.

I went with the 90. So many additional costs associated with the 102 to make it function able. Between intake,rails,decent throttle body and all the extra labor to just bolt it on your $1400+ deep.
If you already have an ls6 you can get 300 all day long for it. Check Craigslist but make sure to dismantle all used intakes before bolting them on. Could cost you an engine! I speak from experience unfortunately.

I can get a ported FAST 90 for $1000. Seems kind of expensive. Is that what they go for? A new 102 is quite a bit less than that. Granted I'd have to get the fuel rails...
Fitment on my car will be different as I've done an LS swap into my 944, I don't have an F body.

I have a cam already, a 226/230 EPS one. On the dyno logging with HP Tuners showed a vacuum in the upper rpm, pointing to an intake restriction with my current stock MAF, ported stock TB and ls6 manifold.
I've sourced an SLP MAF, FAST 90 TB and am looking into intake manifold options of either FAST 90, Fast 102 or an LS2...
