Well right know i am runnin a 3 speed automatic but a four speed manual is in the near future. Im not takin this to the drag strip but i expect to be real quick off the line. mostly i do city driving not much highway driving
I'm runnning a 3.50 gear and would not recommend going much higher (numerically) unless you are considering an overdrive or don't drive on the highway too often. BTW, if you are changing transmissions, why go to a 4 sp? Look into a T-5 or Tremec.
