I have a 01 grand prix gt with 190,XXX on it.The tranny has been rebuilt before. I have considered buying a L36 with around 89,XXX miles but I was wondering if i buy the ZZP Z3 Turbo Kit and the HD transmission Upgrade kit will i need anything else for my car to run right. This is my daily driver so im not looking to do any other mods like a cam,lifters, or catback exhaust. I dont do burnouts but i do occasionally get on it. Also what would be my recommended top boost to run safely. All help appreciated. Thanks
