HP Increase

[Whyte 2002 SCT]

I have a 2002 ga gt sct.....anyone know of any mods i can do to increase my HP. So far i have added Borla exhaust and a K&N air filter. I jus added a Air/Fuel Ratio gauge for future mods so for now i think im all set for what i want to do next but im not sure what i want to add. Please help

Well, I'd make a trip over to www.gaupgrades.net... it's in need of some updating, but most of the info is current.

I'd start with a JET chip or similar chip, followed with an injector upgrade, or possibly a NOS system.

If you want to go into it seriously,then you'd be looking at:
Port & Polished intake
Ported Exhaust, Exhaust headers, high-flow cat (or gutted cat)
Supercharger/Turbo Charger, with intercooler and possibly pre-charge-cooler,
Forged 10:1 pistons, forged connecting rods and blueprinted Crankshaft,
High pressure fuel pump/Fuel Pressure riser, upgraded injectors,
High performance Camshafts, and valves possibly
MSD4/6 ignition system, 8-10mm wires, iridium plugs...

That's just for engine power, you'll probably want to stiffen up the tranny and then start in on the handling & braking.. I'd personally go this route:

1. Level 10 torque converter and transmission valvetrain upgrade
2. Eibach lowering springs and Monroe Sensi-Traks
3. Front and rear swaybars & STBs,
4. If you have the spare change laying around: RSM's supercharger setup.

Youll probably want to upgrade the brakes while you're at it, because 60-0 is kinda important too :) I'd go with KVR performance's slotted discs, and EBC greenstuff pads. while you're at it, I'd go with goodridge's braided brake lines for te front & rear also.

Best of luck :)

Great info, thought I'd like to straighten some things out. First Jet isnt a chip, its a module (just a little pet peeve) Second, 10:1 compression will be way too high for forced induction. Get 8:1 or 8.5:1. Next I wouldnt get Monroe Sensatracs, I'd get KYB or Koni.
