Default Should I Buy A FAST Throttle Body or ASP Pulley First?

So I will be adding heads, cam, full bolt ons, & a FAST intake manifold on my Camaro in the near future. But I want to buy a little something right now. I'm thinking either an ASP underdrive pulley or a FAST 92mm or 102mm throttle body. Either way both of them will be on my car in the future but what would make more sense to put on my car right now for the time being? Thanks!

unless you have a FAST manifold you cannot bolt a FAST TB to a stock manifold

Thats 2 complete opposite things that you are comparing to buy, if everything is stock on your ride buy the U/D pulley, the throttle body will just sit in your garage until you get a new intake, like stated above: wont bolt up.

Why waste your money on smaller things at the moment?....save up and get yourself a nice H/C package and a new intake......that will make some power!....

Still deciding on which cam I wanna run. Thunder Racing T-Rex, Magic Stick 4, or Vengeance Vindicator...

Well Heads, cam & intake is well into the thousands...... Hell a FAST intake is pretty much 1k alone. Just wanted to get something before I start saving up

Since you already have a exhaust your better off buying a lid.

Yea those will be going in a bit.... But a rear end is around 1k? & for the cam I'm getting I would need a lot of gear. Something like 4.30 or 454 gears

What gears do you have now in the stock rear? gears that high (low) would make the shifts a lot closer, a lot of people run 4.10's in basically drag cars. Im upgrading the stock 2.73 to the 3.42 a lot of m6 cars came with.

And yeah a 12 bolt or 9" is going to run 1-2k Gears over 4.10 would probably really need to be in something better than a stock rear end.


Good luck with your car though

Um right now I just have stock gears & stock rear end. Thunder Racing recommends for the T-Rex going with 4.30s or greater.

Get the pulley and I think 4:10 gears will work fine. I'm sure plenty of people are running them with one of the cams you're going to get. Go ask around in the manual section.

Before you just start throwing parts at your car, sit down, make a realistic plan. Realistic meaning wanted hp/tq within your budget. Just saying, it'll save you A LOT of $ in the long run. Is the car a M6 or A4? I personally LOVE my 3.42's. With my #'s I still get 28-29 mpg on the highway.
