Hey guys wanted to know if any one has put a fast 102 on a ls2 c6.I have a 05 z-51 6 speed,with lg headers,vararam,borla stingers,160 stat....was thinking of doing a fast 102 but was wondering if i should do a tb,anyone do a 102 to there ls2 without changing there stock tb or heads ?if so what kind of gains should i get with keeping those parts stock? and did you see a noticable difference?

 

we noticed a difference in my wifes 05 auto with the stock ported intake
so i would say the fast would also have the same results or more

 

don did you keep throttle body and heads oem ?guess im just trying to figure out if i need the tb to get most power from fast 102

 

The stock TB will be fine.

 

from what I've read the stock 90mm TB will work perfectly fine with a NA car. a Ported stock TB is the best option. a 100mm TB is considered the best if your doing a supercharger or turbo engine

 

I have a Tony Mamo ported 90mm TB on my FAST 102 intake manifold sitting on my LS2. Works great!

 

Picked up 20whp 27wtq with a ported fast(thats about with it gained through the curve too)... Made 405/407 with the 102, 1 7/8" headers and vararam (tuned)..

 

so i take it the fast 102 is a mod that should be done to ls2 .

 

The Fast 102 is a great mod for the LS2, my LS2 TB is ported as well.
I ran this setup with bolt-ons and made 400 rwhp and 403 rwtq.

 

Either that or a good port job on the stock intake.. I picked up mine NIB off of ls1tech for 700.00 and had C5kid port it..

 

So when I got headers I remember how I could feel the difference .. Is it the same kind of difference with the fast 102 or not as significant .just wondering what to expect

 

FAST 102 could be the best dollar for dollar mod an LS2 can have. Many have reported 25-30 rwhp gains over the stock intake.

Run a search for specifics...

 

My buddy picked up around 20rwhp on his cam only ls2 with one. Not a bad mod. Doesn't seem to do as well on the LS3 cars, though.

 

Correct, LS3 intakes appear to be a less restrictive design than the LS2. Same with the heads.

 

Most of my customers that have swapped an LS2 intake with one of my ported FAST intakes have seen 25 - 30 HP. And this was with the older 90/92 designs. I have some new "tricks" and different porting mods on these 102 intakes that would add measurably to these figures that I wasn't able to perform to the older design intake due to the different build design (the new 102 is a completely different design with removable multi piece runners, etc).

The key is the heads....with really good heads a swap to a properly modified 102 intake is worth in the vicinity of 35 RWHP! Thats a huge shot in the arm and the gains are very noticeable in the SOTP due to highly improved throttle response as well. Its just a great mod....the engine feels even stronger than the sizable legit gains indicate because response is so much sharper and there are fat gains in the power curve everywhere, not just peak.

BTW, the LS2 intake is the absolute worst performing cathedral style manifold....another reason swapping to the best performing intake is such a huge increase.

PM me for details if your interested....I normally keep ported units on my shelf ready to go.

If I were staying NA I would definately do a ported FAST. I plan on doing an ECS or A&A kit in the next couple of months. In the meantime I got my LS2 manifold to a stage 2 and my TB ported by Jeremy Formatto along with a quick update to my tune for $400. His previous dyno's show roughly a 20rwhp and 17rwtq with this. Probably about half of what you could get out of a $1300 ported, but it was fun and pretty cheap.

 

Thanks guys for all the info ,i ordered one yesturday from vendor on forum for $799.00 shipped, i think it will be well worth it,gonna keep factory heads,and tb for now and see what the gains are from tune and the difference in power of car

 

I put a Fast 102 on my LS2. No need to change the TB.

You will get about 20-25rwhp from it.

 

just went from a stage 2 ported ls2 intake to a ported fast 102...even without retuning it for optimum hp,i can feel a big differance in the midrange....!

 

Here is a FAST 102mm on a H/C LS2 car, still had 90mm throttle body. Power gains everywhere. 21rwhp!!




Here is another LS2 intake/throttle body to a FAST intake with LS2 90mm TB. This is an LQ9 engine, thats basically stock. Stock exhaust manifolds, stock cam (190s@ .050 .470" lift) They work well even on totally stock engines! Again Power everywhere and again 21rwhp gained, this was without changing the tune. I simply dropped it on.
