Before i got Stage 2

04_Sti_Blue · 06-17-2008, 01:44 AM

Sup guys, ive owned my 04 STi since it has 0.3 miles on it. And Recently i have been getting bored of the power. I have installed over time a Cat back exhaust, and Cold air intake and Blow Off Valve for asthetic purposes. Well i just recieved my megan downpipe from a online user. So i have recently decided to go with a Pro tune from a local tuner in the SoCal area that i hear is really good. So with the downpipe i have what i need to go stage 2. But i want to throw something else in the mix since im goin to spend the money on a pro tune.

Here is what i have came up with.

1.Exhaust Manifold Crossover Pipe
2.Uppipe
3.Walbro Fuel Pump
4. Injectors

That is alll i have came up with. So with the addition of a new DP what else should i get that will gain my car the most power? Preferebly top end! All help is greatly appreciated! Also since in installing the downpipe is it worth it to get the waste gate port and polished?

Get a fuel pump for sure. As far as porting and polishing the turbo, its a pretty good mod IMO. You will spool about 200-300 rpm sooner and hold boost better to redline. When we port and polish turbo's we do the compressor inlet and outlet, the hotside inlet and outlet as well as the wastegate. I also suggest porting the stock exhaust manifold, you will pick up about 75% of the power that a true header will give you for about 1/2 to 1/3 the price. PM me if you want some pricing on porting or check out my thread in the vendor section about it.
