Friend of mine with a 2TG powered Corolla KE20 and T50 trans is at the moment on a diff shop for a new gear ratio.

He uses now a 4.3 diff ratio and want to go to 3.9:1

for his calculations see: http://www.ke20.nl/Corolla/gearratio.jpg

Some further specs:
red line 7000 revs
Tire 205mm 60% 13 inch

He now drives on 165/65/13 to 165km/h on 7500 revs in 5th gear ??
Way too short

Any comments from you on this matter from transmission specialists? :P

He mounted a 3.3:1 diff and locked it, 100% LSD by welding, and it runs now 3700 revs in 5th gear on 120km/h (74mph)

For fast accelerating he has to go to the 4th gear but it is much nicer drivable now!
