oh say i do a lot of highway driving, and when im on it im right at 2k rpms. at 60mph.. would getting a longer 5th gear be a possibility? you know for gas and longer engine life? like i'd be doing 70 and be at 1700 rpm or so? good idea?? car, 97 gt 5spd

the only real way to do it is to buy a Viper spec T-56 with the longer 6th gear ratio. This is going to run you about 2500-3000 for the transmission and then another thousand or so for other parts and labor.. not going to be cost effective.

it would take you years of highway driving to lose enough money in "worse" gas mileage with the T5 to spend more than it would cost to swap in a T56.

not to mention a longer 5th t5 would be useless in the city. i shift into 5th at 40mph with 4.10s and im at 1300rpm...almost bogging. a longer 5th with stock gears would proboble be WORSE on the car..so u would be driving around town in 4th gear using more gas than u would in 5th with a stock t5. lol so your screwed either way on this i would think.

t56= non cost effective
t5 longer gear...same situation
