First a factory appearing “Sleeper” STI making 900AWHP on a 2.5L, Super 99 72mm turbo and sequential trans. The second is one of the most wild street Subarus they have ever filmed, fitted with a 6 cylinder 3.0L Subaru engine, 72mm Borg warner turbo, and sequential trans. They take both cars out for some pulls, strap in and enjoy the ride! Leave a comment
