Tb & Intake

**SSzoe** · 02-08-2006, 01:29 PM

I would like to upgrade to add on a new throttle body without taking to big of a hit to the wallet....I am in love with the FAST LSX 90mm tb and intake but WAY to much for me.....I was thinkin simple ls6 intake and maybe a BBK 80 MM throttle body??? Let me know what you guys think and if you know of a place where i could get something cheaper....Already checked ebay and they didnt have anything on there

Now wait a minute here pilgrim...what heads/cam you got there....no reason and put 50lbs of shit in a 30lb bag....you may want to get your stock TB ported and polished.....without proper flowing heads and a decent cam lift you may be "pissing in the wind".....but lets see what you got...and get you hauling ass....

I am with Sarge.

LS6 intake and ported stock TB. At least on a bolt-on car.

i heard that the FAST 'system' (TB and manifold along with the fuel rails and high fold injectors) really wakes up when you have a nice set of heads and cams. I have them sitting in my closet right now. Just haven’t found enough money to buy the heads/cam That true? Oldtimers?

depending on what heads and cam you have, it could be a waste.
if you have a hot h/c set up, then get the fast system.
if you have a street/mild h/c, dont bother.
the fast set up is best for bigger displacement motors

Well, my goals are to eventually bore, stroke, and supercharge her when I get out of collage.

OK...OldTimers huh

Rule of thumb for increasing top end air flow...ie...intakes...TB's....if you have not modified your head flow numbers by at least 20% your wasting your money...

hmmm so you won't even see any power gains from a ls6 mainfold and BBK 80 mm TB unless you have H/C's?

**Sarge** · 02-09-2006, 08:32 AM

Mebbe...but you probably would lose a shitload of low end grunt....

**TransAmMan** · 02-09-2006, 08:49 AM

wow really?

**Corona-Extra** · 02-09-2006, 12:21 PM

soooo.. with boring, stroking, and supercharging, would the FAST set up work... i believe it will... but im jsut wondering your opinion.... old man...

**nhraformula** · 02-09-2006, 12:53 PM

the fast will work with a stock cube block.
it just wont work better than a ls6 intake.

Sarge,
how will the LSX work on a LPE 383 475 HP package with the LG
long tube headers. I was told by LPE that the LS6 is about right
and that the 78mm is plenty. Is the LSX a waste of money.??
we are also going to install 1.8 roller rockers and new springs. The motor
has about 6000 miles on it. I like the torque that this long rod motor
makes!
thanks
lpe
