Now that is 600 i have towards the fast i just bought. I also got a group purchase deal on the fast 90/ ptm 90 t/b for $1000 from texas-speed. So i spent 400 for a fast 90/90
but then theres people like me with having an issue with getting rid of stock parts...
its a habbit i really need to break!
This is such a great informative thread. I think that table that Tony made should be a sticky somewhere.
Right on man.

From what I am reading, it seems the throttle body opening in the LS6 intake is the main problem with its design for higher hp applications. I would really be interested in the results of how a Professional Products 90mm intake holds up against a FAST 90 intake. I am seriously considering purchasing one. Hell, I would even be willing to ship it to Tony if he could do a true comparison side by side. From the way his company does buisines, I feel he is someone who could be trusted to show the entire truth and cut all the bs out.

BUT saved the motor and dropped it into a 2000 C5 M6 
....my heart pounds everytime he redlines it I don't think this was already mentioned or anything but the Fast LX intake manifold has a bolt-on direct port nitrous system available for it.
The LS6 isn't direct port plug and play.
Of course the upside for the LS6 is that it doesn't have that ridiculous coloring along with the tacky FAST and whatnot not only colored on the intake but raised up so that even if you paint the damn thing you can still see it.
For the price I don't want to have to pay to drive a billboard around....
Stupid looking fast intake with red engine covers on a Z06 vs. no direct port bolt-on available plus it already comes on the car.
I'd say it's a give give on a stock cubed mild set-up as far as expandability.

Just get out your sand paper and you can remove the FAST logo and the WILSON lettering and then paint it what ever color you like...that is what I did..I am not much on decals and advertising either on my vehicle..

Ugh even more work!
First you have to go out and work for 40 hours to pay for it (also have to spend cash on the TB) then spend another 3 hours sanding and painting it.
Oh yeah, then you have to do the nitrous install

!I used a power sander to clean it up..it only took about a half an hour to get it looking good..

Wow, glad I did.I almost asked this same question!!! Am I a good boy?
Looks like a Fast 90/90 is in my future (well, not exactly NEAR).
Who can I send it to, to do the porting for me?
PS, this is sticky worthy.

Okay so for the consensus is anyone agreeing that if you have a LS1 intake you get the LSX FAST and if you have the stock LS6 intake you switch that out WAY late in the game?
Late as in if you are going NA and after a camswap just before you go bigger cubes (or maybe just before you do a headswap/porting) or H/C.
I really don't think anyone with a vortech, ati procharger, or a maggie is going (well especially with a freakin' maggie what the hell am I saying -er typing) to get any gains. Same goes with a turbocharger.
I heard that the LSX doesn't seal/fit as well as the LS6 intake (or LS1) as far a boost is concerned. This was just hearsay on the forums though I could easily believe it. Besides with anything involving FI anything you spend on the FI kit will give you better cheaper gains than cashing out for a intake or port work or even a bigger TB.
I think we should redo this thread with a new one including a poll with lots of options to choose from.

Good man This thread is a century old but still the LS1 info will not die. My 01 WS6 ran 13.18 stock and now with only LTs, catless Y-pipe, built T56,LS7 clutch im at 12.49@112mph with fuzion ZRi street tires, leaving @2k rpm. I like when us technical guys that RESEARCH hrs+hrs to know how to squeeze the most hp per $ out end up embarassing guys that buy what they read online or see in magazines. The bigger the company, the more advertising. Most people (me) put GM parts down cause the high $. In some cases like the LS6 intake when its online everywhere as a top bolt-on because its cheaper than the FAST shouldnt that be a dead giveaway?!?!..My buddys 00 SS runs 13.8 and he's getting full exh,medium cam,241 stock heads and he wants FAST even though he just bought a LS6 intake. He wont research or listen to me, but he can keep the LS6 int and put $800 to get head work and the LS6 alum int. he bought port matched/polished and make maybe 25-40rwhp, instead of spending it on a FAST and leaving heads stock, and get just 15rwhp from the LS1 to FAST swap only! How can I make him get it? He is a member on here! He could get his exhaust, cam,FAST and still only be .8 tenths faster and put him with me and I just have exhaust, that would be bad for him...I want to help him

i meant intake manifold...have the ls6 intake manifold right now...wanting to go with the FAST 90...the bbk TB is just a supporting mod i guess, that is already a 90mm TB and im not sure what the size of the ls6 intake manifold opening is...cause i had to get a plate that would allow my 90mm tb to mount to it.
I'll throw my results; I gained 14rwhp from LS6/ported TB to ported FAST 92mm/92mm TB BUT only from 4300rpm to redline 6500rpm. I have stage 3 ported 243s with bigger valve and a small cam.
Its worth it it, but it should be the last mod IMO.

already have a hefty cam with the ls6 intake manifold...going with some afr's or trick flows...just asking because im yanking my motor and rebuilding it...not stroking or anything just time for a nice clean rebuild and trying to get the most out of internals and boltons and id rather put all the goodies on it before i stick the motor back in and change my mind.
