Okay if I may let me make some corrections to some of the statements made here. First you DO NOT need to do anything to your fuel system unless you are upgrading the turbo. It comes rich from the factory already, the worst you could do is add more fuel to it. Next the COBB AP is a great add at an inexpensive price. With that for tuning all you need is to fill out a form with COBB and they send you new maps/tuning. For a first time start on a WRX I would highly suggest the following with prices and where to get them:
Start with the Invidia Cat-Back and Invidia Down pipe---$1019.31 at rallysportdirect.com
Next get the COBB AP with Stage 2 MAP--$595.00 at rallysportdirect
Those options will get you about 340bhp at the dyno, and about 290whp.
Next go with the Full Race 1.5 scroll header/up-pipe and turbo upgrade--$4427.00 at full-race.com
Tial Q Blow off valve--$260.00 at full-race.com
DeatschWerks 650cc Top-Feed Fuel Injectors--$379.00 from hptmotorsports.com
AVO 245LPH High Flow Fuel Pump--$305.00 from hptmotorsports.com
Cobb Tuning SS Turbo Heat Sheild--$60 from rallysportdirect.com
Process West TMIC--$898.44 from rallysportdirect.com
Mishimoto Radiator and hoses--$342 from ebay.com
For suspension yes it sucks balls stock so I went with a megan coilover damper system. Also improved bushings throughout is a HUGE improvement. pretty much I went to hptmotorsports.com and if they sold it I bought it. Anyways hope that helps.
Now on top of that I would get any turbo timer you would like. I personally like the Greddy Turbo Timer II. Also the stock clutch and pressure plate is completely worthless so at the same time you do the turbo add this as well:
ACT Stage 3+ Carbon Clutch kit--$809 from hptmotorsports.com
ACT StreetLite Chromoly Steel Flywheel--$296 from hptmotorsports.com
Now the stock tranny will break easily so if you plan on revving up and red line shifts I would look at having your tranny rebuilt, your car will be out of commission for about a month but well worth it. Go to importperformancetrans.com, its about $2800 to have it done but it will be basically bulletproof after.
Or just go EWG and it's only catless (at least partially) when you want it to be
I agree with syno, I'm seeing 90% idc's at 19psi on the stock turbo. My next step is to go with ID 1000cc injectors and a pump, but that's only when I go E85 or 20g (probably both at the same time in a few years).
so your at 90% with stock pump too? goes to show you a pump doesnt do much either (at this point). wonder if anyone has taken the time to calculate the 160lph vs 255vs 245 avo and have a set point for power and boost so people know when they need to buy one.
