how much it could cost having a sti .. wanting to have 500hp..?? with gt35rstock location with pump gas and meth?

This question makes no sense grammatically. You should use the money that it costs for the STi to be tuned for an education.

Drugs are bad for you. Stay in school.

Are u asking how much just the tuning will cost? Al uses ECUTek primarily so if it is ur first time, it would cost roughly $400 for the license & then whatever they charge hourly. l would guess $150 an hour & at least 2 hours of tuning time so $700 for the tune. That is just a rough estimate. If u already have another type of EM then u would just pay for the tuning time. If u r asking how much to get 500hp then l would have at least a budget of $6000 & then another $2000 set aside in case u need the engine rebuilt. 500 is at the very top of what the stock engine can handle & even then not for very long.

The two morons above obviously r not Subaru people ans just wanted the 2 points. Not everyone knows who Big Al is.
