My "lightly modifired" (<$500) WRX makes 5.9R/Ts look silly. This guy tried to race me from a stop light in one. I heard him rev wildly as I launched normally. I upshifted into second at 5,000rpm, floored it and still whipped passed like he stopped.
Stock v. stock, the WRX is faster.
Stock WRX v. Modified 5.9R/T anybody's guess
