what intake is best for ls1 i was considering the new fast 102 intake but after hearing not so good feedback about it and all the work needed to install. i desided not to plus the price too much work for that price and not that much hp gain. i was thinking of just keeping my ls6 intake that came with the car. what do you guy rec. is there any worth wile mods to do to the ls6 intake. and how big of a tb can i put on it. my car is gona have heads and cam on it so i like to impove the intake. what other intakes are worth it. thanks for the help. i will also be changine inj for my setup too.
I think the best thing to do is get a Shaner S3 TB and throw that on. I'm in the same boat as you. My car is a STREET car, not a track car, and as being such, I simply can't justify the price.
If I was racing on the weekends though, you're damned right the 102 would be my first coice though.

im going to throw an oddball vote out there for....
a weiand street warrior!!!!
no but seriously. try and find a used fast 78, 90, or 92. i would think theyre the best due to cost comparted to a 102...

I had a weiand street warrior on my car and it was AWESOME. But it got ruined when I was driving home one night and hit big foot. It totaled my 2005 Trans Am WS6.
If you believe anything I just wrote then I've got some ocean front property to sell you here in Iowa.
I say save your money for your H/C set up, the extra money could be the difference between a set of ported 243's and being able to buy some AFR Mongoose heads. I've seen a few threads where people have ported there LS6 intakes to fit an 85mm TB.

Grind the water pump and buy the necessary parts for it and its not that much trouble. I would however relocate the MAP sensor becuase it is very close to the firewall. I"m just waiting for mine to get a little extra movement and break off. A used FAST is probably gonna be pretty hard to find plus you may end up with someone elses headache. I'd just keep the LS6 intake until you got heads and cam. Make the intake your last mod. X2 on the Shaner S3 those are works of art. It'll give you great throttle response.
Op you have been misinformed about the 102. Your ls6 is fine for now. Honest on a head and cam car the fast intakes beyond shine.there is no cheap upgrade from the ls6 unless you sell it and find a older used fast intake.but its not really worth it untill at least a cam gets in there.as far as the TB goes just stay with your ported stock one.there is no need to spend money on a TB untill the h/c have been done. I swear the more threads i read i just hear about people wasting money.there is so much you can get out of these cars and do it on a budget.
I agree, they are not any harder to install than any other intake. If you read the directions there will be no issues at all with the install.
Here is where I dissagree with you, I have done a TON of FAST intakes on non H/C cars and they still make ~20hp
My stock LQ9 shortblock, stock cam, with LS2 intake, swapped to FAST and gained 21rwhp. No tuning
2007 Silverado 5.3L with TBSS/NBSS intake, 100% stock, swapped to FAST and gained 20rwhp, no tuning.
1998 Corvette, Ls2 swap, Heads and cam, gained 20rwhp over stock LS2 intake
The point is, they work just as well on H/C cars as they do on stock cammed cars.

Sweets when i get to my comp ill clear some things up on my post.hard as hell to type on this phone.i will say i was meaning a fast on a stock internal car is pointless. And gains will depend on setup,if the intake is ported,and how high your going to spin it. I will explain more tomm. Im putting a ported fast on my cam only car i wish i had the synopsis sheet but i haven't made it that far yet lol but that would help show what im talking about

i'm thinking of the Lingefelter, i think that's the company, do a modified ls6 manifold with a 90mm intake opening and throttle body, they had dyno results on the same motor with only a couple of rwhp difference, maybe 5hp at the most.
Here's the link, sorry i was wrong, it was 4hp difference between the ls6 modified and the fast 90, there on the two graphs at the bottom, both compared to a ls2 manifold.
also has a option if you send yours in for a modified one which makes it a very cheap manifold for the price.

auslls1 there is a company you can send your ls6 to and they will put a 90 mm snout on there, i have talked to people that have had it done and they were no to happy with the cost and the quality of work done, i honest would just stick with your ls6, all your going to do is over pay . i have seen dyno graphs on the fast and ls6 on stock internal ls1s, and honest i didnt see it beeing worth the extra money when the motor still has stock internals, a ls6 will flow beyond its fair shair for a 300 dollar intake, and the cost of even a used fast with tb could pretty much pay for a cam swap. i guess is what im saying is i would take a cammed ls1 with a ls6 over a stock ls1 with a fast lol.now if you really wanna talk what is the best intake imo its a mamo ported fast, some will say its a over priced port job and it is expensive but there is a pretty big gain over a untouched fast. worth the money?some think so , i just will port my own lol

oh ok, all good then, yeh mines getting a 383 stroker kit as we speak and will run a decent cam 235/243 113 lsa from comp, if its worth it i'll swap to a fast 102 manifold with a 92 mm throttle body, other wise will stick with ls6, but the fast might be worth it then in my case?
Yeh when i first read about the ls6 mod i was a bit suss on the craftsmanship with it being a one piece intake.
