Hi

some years ago, i found a website with some gearing configurations mixed with 5/6 speed ratios,jdm and hks gears with ratios and teeth.
Tips to get the best way for accleration and top speed for you

i only knew that recommendation from site was for a 500awhp powered evo 8.

maybe somebody can help to find this website again.

 

Do you drive the car on the street at all? How much torque does it make?

 

It have 550nm bottom to mid range. Max output is 450hp at 7000rpm.
Its for german autobahn.

 

Do you want the gear acceleration biased, or, do want lower rpm for high speed cruising?

 

the only way for me 6speed is to change the final drive to 4.0.
But is there a possibility to swap the 4th from 5speed into the 4th of 6speed?

 

Nothing from the 5spd fits in the 6spd

 

I have a 6 speed with the taller final drive and the stronger gear-set that came out in 2014. (shep built).

 

The 4.0 final drive will shift your RPMs lower for a given speed. In the OEM 6 speed trans, gear 6 at 75mph is about 3200rpm for a nice cruise. If you are going to be cruising on the autobahn, the 4.0 final drive will give you even more top speed. You will lose torque, but your car will be moving fast in 6th.
