I got a 2005 manual GT, i'm just looking for a way to moderately increase (20-30)my horsepower/ lowend torque similar to the Audi superchip without installing a 3000$ Greddy turbokit..is this possible? if so will it void my warranty?

Thanks!

there have been plenty of threads on this subject
the usual intake/exhaust/header combo won't do much, and the little it does is usually in the upper rpm ranges..

Without FI, you won't be able to increase your lowend torque much at all. A tuned NA would probably be able to gain that 20-30hp you are looking for, but it will all be in your mid-high range rpm. Bite the bullet and go FI.

hehe you came over to the major hp upgrades to ask about a moderate hp improvement...

4.77 gear + lightened flywheel might do the trick, all other moderately priced options only effect upper RPM's. What about porting? I think that's upper RPM's too though.

^it is..the ports on the 13b-msp are pretty large already.....i think most porting jobs i hear of are only cleanign up the existing ports..not enlarging them

Air intake, hi-flow cat, and canzoomer piggy back ECU would give you the best chance at 20-30 whp, but tq will only be mildly improved (not 20-30 lb.-ft.). Otherwise go FI. Also piggyback ECU would void warranty, that is why a lot of the people take them out before they go in for service.

Pull out 13B and insert V8....

I dont see how horrible tasting tomato/carrot/celery juice will help.

Interestingly, you really cant get 30 ft-lbs for less than what it would cost to get a greddy kit. Go FI.
