The crew down at RevWorks (in sunny Florida) has put together a mind numbingly powerful 2015 Subaru WRX STi. At 3,386-pounds, the STi rolls away from the factory with 305hp and 290 lb.-ft. of torque. It has a 2.5-liter sequentially fuel injected H4 engine with an intercooled turbo. RevWorks adds an upgraded turbo kit (ETS 6266), a set of Stage 2 cylinder heads with a full compliment of GFC valve train components, a Radium dual-pumper intake setup, and a closed deck engine block stuffed full of Wiseco 10:1 pistons. It’s running 38 psi of boost and E85 fuel. This video will probably tell you more about STi modification than you ever wanted to know.
