3.8L Throtle Body
 

I have a 99 Firebird and i was trying to get a bigger throttle body and some spacers but i'm having a hard time finding anything due to the fact its electronic and not cable driven. Any ideas or suggestions?

why are you looking for a bigger one? Stock one suffices for a while. What mods do you have?

He currently has.....none

will a lt1 throttle body work

not in a million years lol

They deal with the GTP's 3.8's ( same motor just forged pistons and rods). I got all of my valve train through them and also My Pistons and Rods for my 98 Firebird.

Also people have modified LS1 Tb's and Mass air metors to there 3.8's.

And Caddy Northstar throttle bodies.

Man what a shame. I just threw one out. :lol:

I think most will agree TB spacers are useless, just makes a sound

I hate this electronic one, i can stomp the gas and see the lag between me hitting it and it registering, its kinda fustrating

Thanks jeff, didnt find exactly what i was looking for, but they did have some other parts i needed to get rdy for atco next month.

You have a pretty fair amount of control over the TB in the tune. If you are into drag racing you can actually do some pretty neat stuff with it, like use it as a 2 step :) If you have a laptop, get yourself a copy of HP Tuners and start reading up on it. You won't be disappointed.

Actually we dyno tested a TB spacer on my 98 Firebird. For 40.00
It gained 2 hp over the entire curve and 3 ftlbs of Tq. Not to shabby for 40.00. Thats like a K&N airfilter gain.

To be honest I wouldnt mess with the TB until you get a ported intake and Heads and cam. I was making great power with the heads and cam with stock TB on my 98. The TB was going to be my next mod but I never got around to it.

I think a nice set of Roller Rockers, Headers, lid, and a full exhaust will be a good start to what you want to achieve. That should get you around 240hp and 250tq @ the motor. I would do that along with a stall converter until you decide if you want to do Heads cam intake, Turbo, Supercharger, or nitrous.

We'll have to talk about this next time we meet up
