how come fd plays role in the rpm shift landing point?
assuming the use of jdm k20 gearbox 6 speed
red is using 4.7fd
blue is using 5.4fd
which one would be accelerate faster?
edit: thanks for sharing your info.
Hey Sorry for the late reply - I am soo slack..LOL..
1) going with a taller final drive gives you more torque by mechanical multiplication. The higher the ratio is, the easier it is for the drive axle to turn the wheels = faster acceleration. Your rpm shift points don't really change, but you'll find yourself shifting at a lower speed.
2) With a shorter final drive, you achieve a higher RPM @ a lower speed, the acceleration on the 5.4 would be faster
Its no different from installing a stock shifter. Nothing special and easy for DIY.
Just make sure when bolting the shifter to the rod, that the movements don't bind.
