ive got an 89 notchback and i just purchased a d1 supercharger...knowing that i would grenade my world class t5, what should i go for a t-56 6 speed or a tko500 or tko600.....are there any guys on here with 6 speed fox body's and if so do you like it....i really wanted a 6 speed but since the overdrive gears are so similar between the t-56 and the tko's that im not really sure what i want anymore
