Gear Ratios Options

[BonzaiCelica]

I was wondering what the purpose of the final drive gear ratio?

also what is this? http://auctions.nengun.com/item/k113042803

best idealistic trans i can think of for an NA 3s/5s would be a 96-99 s54 with the s51 5th gear for lower rpm crusing speed (higher top speed) and the LSD from an e52/56

E153 in a N/A car would be a dragg

for road use yeah that probably pretty good, it would help if fourth was actually a little longer too, i find theres already a big enough gap between 4th and 5th that means as soon as your in 5th all acceleration dies until you get a bit higher up the revs, at which point aero kills

for track though the e56 with 4.9 final drive puts the wheel torque up to about the same as a v6 conversion but in 3rd/4th/5th the torques hitting the ground at higher gear speeds so should make for a quicker car, fuel economy is gonna suffer though but its cool its a track car
