Thread: 2004 Grand Prix GT2 How Can I make it faster

You'd be hard pressed to beat any of the new high feature dual cam cars...hell even the new Camaro sixxer is rated at more power than the old out going 3V Bullitt mod motor V8 Mustang.

I suggest reading and research, OP. Your N/A GT might break into the mid 15's...which is about on par with a stock four banger Cobalt.

Hell, I was pedaling TravisGT2 in my intake/exhaust 2.2 Cobalt...and it didn't even break 140 horse to the wheels.

I'd tell you to just turbo it.

But then you'll need a transmission to hold the power.

So, you're probably looking at around 6~ grand or so to do it right from scratch.

Staying NA means you'll be going nowhere fast, with the added bonus of being poor as you do so.

i was mid 15's with just hv3,downpipe,intake,tune.
with my current mods and 3:29 gears im sure i can get into the 14's, just need to do my gear swap and try.
current mods in sig. got retuned in-car when er rockers and l67 HVTB got installed

z34 did it with less mods then i have, so i just got to learn to launch.
