I just ordered a new downpipe and exhaust for my car, along with some gauges, and a turboxs utec and tuner. what else can i do to the car to squeeze out some more power, short of replaced the turbo with a larger unit? thanks

 

Try out the Evo sections. I know that a few Evo owners wander through here, but you're more likely to get a faster hit in the Evo sections. But, since I hardly know anything about Evo's, I'd say Body Kit....

 

Replace the intercooler. Get the AEM Intake. I would prefer to go with vishnu rather than turbo XS, but thts just a personal opinion. you can also order the Ti strut tower kits, which are lighter to save you some weight. The stock wheels are nice and strong but i'd suggest getting lighter wheels with the same specs(17X8.5), and keep the stock tyres. they are awesome track tyres.
If you really wana get some extra power outta ur engine, go for the Nitrous Express N-tercooler kit ( the site ses that it'll provide 50+ hp for ur car, but i'vnt got more than 35-40 boost) Still its a valueable mod. While ur at it, get a nice engine management unit that can **** with your AF ratios, and then change your AEM to HKS Typhoon intake. Installing a HKS typhoon intake without the Feul Management WILL stall your car.

All this shud push u to 320+whp. Enjoy the car.
