hey whats up people, my name is Jason and I have a 1999 grand prix gtp. I bought the car about 6 months ago. Recently the tranny has failed on me and I am no other choose but to replace it. I dont want to sell it because the car has potential to be a fast running car. So thats where I stand right now. I am pulling the tranny and motor to build it. That is why I am on this site so I can hear from people that have done it already and get good leads on what i have to do. Really I am looking to get about 300 hp out of it but I know it can acheive way more. Thanks
