Im busy with an supercharged v6 but wan´t some longer ratio´s on the mt75 as ithink the rpm on the freeway etc will become too high.
Another option Micheal is to change the 5th gear in the MT75 to the diesel version which is 0.76 compared to the petrol MT75 ratio of 0.83. that would leave the first four gears as standard for acceleration, leaving 5th for cruising the freeway.
IIRC I think I read that changing to the diesel 5th gear reduces the RPM at 100kph by roughly 500RPM.
