I currently have a 2006 STi with full bolt ons (Intake, TIP, UP-Pipe Headers, Down pipe, Exhaust, 255 Fuel Pump and Cobb) the car is fast but a modded 135i will take it out in a straight line. Have not had a chance to run one but being weight of the cars are very similiar - a stock turbo STi will only make maybe 315-325 AWHP and 330-360 AWTQ with out Meth
. The STi's piston rings are just to weak to continue modding. I am currently looking for a 135i and cant wait to have one of these for my own. 135i is just such a better car for Daily Driver.
