So I need to order my clutch this weekend. My transmission is from a 07 non turbo Impreza. It's a push style clutch, just like the same year wrx. Are all 5mt push type clutches interchangeable? A non turbo exedy stage one (#15801) is only rated for 202 ft/lbs torque versus a WRX push type stage one (#15804) rated at 301 ft/lbs. Are any modifications need to use a turbo clutch on a non turbo trans?
