I have an 04 WRX, what does it take to get to the 12 second range (1/4 mile). Is it possible on the stock turbo or is a bigger turbo and intercooler needed?

i got a 1.72 60' foot and only managed a 13.2 @101.8 . but i have got a 13.07 before. trying so hard to get into the 12's w stock turbo. do you guys have a header? what engine management and what psi? im only using accessport now. and the top run boost only maxed at 15.5... and of course i run at atco so these times were with wet tires. (you cant avoid wetbox).



and for those worried about there trannys. i have 48 launches at the track on the stock 02 gears
