In the tech data, the T3's were capable of producing about 56% hp gain on your car....that would be about 310-320hp? And that's just the turbo, you know. You still gotta buy the wastegate, intercooler, ducting, blow off, pipe, etc, etc, plus all that other stuff we talked about...that's not a kit, just a turbo.
Just because it says for engines capable of 525 hp doen't mean it's gonna make that on yours...
If you have such an awesome supply of knowlege and expertise at your disposal, one wonders why you'd come here and ask a generic question about what you want to do....
Keep digging the hole, this is getting good...
