I'm about ready to pull the motor out of the car for huge HP/torque upgrade..... I'm thinking I might as well get it over with and upgrade the transmission... it seemed to run smooth the few times I drove it last year but.. its basically the only thing left that isn't new on the whole car.. id like to do a 4 speed swap but I will probably just do a TH350... I'm looking at the TCI street fighter... thoughts?
