4.6

  1. Engine & Drivetrain
    Hey all, I'm considering changing my 4.1 ratio to 4.3 or 4.6 for lower 4L and to raise the engine RPM for the hiway. Its a 93 GQ td42 with the 4 spd automatic with TC lockup. Currently 4L just isnt low enough, and on the hiway with the torque converter locked up it runs around 1800 rpm at 110kph...

    Wanting to know if any would know how many teeth should be on the crown wheel and pinion gears for the 4.6 ratios. Cheers
