Not sure what your experience is with an actual gtir , if you've owned one, ran it with the stock 28 turbo, or what engine manement you've had eg jwt, cal, aem , piggy etc. when I had my gtir in the 99 sel on a jwt 750 cc injectors walbro 255 with a a maf the car made 265 whp 240 lbs torque on 91 octane at 14 psi. However, the true limitation is that the t28 on a jwt (for me) didn't like more than 17 psi on 110 octane. Regardless , I ran 7.68 7.7 7.75 s all day on the four door at 17 psi with 22 inch slicks on a 25 rim. A slightly bigger turbo finer tuning aem ems c16 makes a big difference. Rev limiter is now 8500 and the car pulls hard thru 4th gear without any cutting off. By the way, just because you can make 400whp or 350 lbs doesn't mean the car will run fast. It takes knowing how to drive and understanding psi slicks launch rpm and having the right combination of other factors. My goal this summer is to run an 11.2 1/4 mile with my set up. If I can't, will look for a bigger Turbo. Nonetheless, these sr20s don't stop impressing me.
