i already had a 3.5" tomei exhaust on the car, 3" dump no cat, cooler, pipe work all came with the turbo. sweet im just chasing info at the mo as ive read this thread a few times over since i put this turbo on. yeah shes still a 2.6 if she goes ill be looking at going 2.7 or 2.8. i know she'll get leaned on abit on a stock motor to make those numbers but she is my daily driven car and the occasional track/drag day. for the time been 600 would be the most but once built 700 will be my goal
