I'm planning on going with a sp63 or sp67 turbo, i was wondering if the sp gen2 tranny would hold the power of both of these or do I need to go with the sp400? I would only run race gas maybe 2 times a year since I don't have access to it in my small ass town. But I do wanna get a menthanol (spelling) kit for when someone worth racing pulls up next to me and i wanna boost a little higher. This car will be a daily driver and might be taken on a few trips through out the year (3 hours driving). I've searched and read up alot on these but haven't seen any people posting my situation so if someone could please help me out. Thanks in advance for all your help.
