I have a 5sp manual gearbox for sale out off a naturally aspirated engine. I took it out of the car I crashed. It has done 138,000km. In the 2 1/2 years I owned the car I had no problems with it at all. No crunching or difficulty getting it in gear. It is in fine working condition. I need it sold! I am in Brisbane $325- Express interest via here, PM or mobile (0421758166) Cheers, Nathan.
