After T-Back What's Next for HP?

JavaREX · 07-11-2005, 01:29 PM

I have installed a T-back exhaust, uppipe, COBB Stage II. Overall I am pleased but I like to look forward to the next project. What are your opinions on the next part/parts to change to get more performance and/or HP out of a WRX?

I am thinking less expensive than a new turbo or is this the only logical next step? Most of the next step options I can think of most are very controversal (ex: BOV, pulleys, intakes). Are replacements spark plug wires and/or plugs an idea?

Please help-I need more ideas on where to go next??? Once you start you just cant stop!

BOV is more of a sound mod its only worth it when your running over like 20 or soo pounds of boost. Pulleys are useless, intakes are useless inless you change the turbo. You could go bigger intercooler and youd see some gains there. Or headers but you might loose some low end. If i were you id upgrade the turbo to a vf34 or vf 30 cause those are the only maps up on cobbs website inless you can get a street tuner and get a vf22 or a big 16g or 18g.

Thx. What type of gains to expect from a larger TMIC with my setup.

Depends on how much boost you are running now. The TMIC wont add any horsepower in itself but it will allow you to safely turn the boost up.

not really do you see how tiny the stock IC is..............anything bigger is gonna be a huge difference.......and it does add horse power go to turboxs.com and look at there stage3 it put down 242whp as opposed to there stage 2 which put down 227whp. And no you cant turn up the boost any more cause the most you can go with stock turbo is 18lbs with out blowing the turbo.

I wouldn't go over 17psi with the stock turbo and I wouldn't buy an upgraded IC until I did a turbo upgrade. You could get a VF34, 255lph fuel pump and some STi injectors for probably around $1k. With that don't be supprised to see around 280-290whp.

The reason TXS's stage 3 makes 15 more HP is because they upped the boost from something like 16.1 psi to 17.1 psi.

15.1 to 15.4 there dyno reads real high too.
