I have an 86.5 N/A supra. Recently i had the 1jzgte engine installed with the supra turbo gearbox. Changing the gearbox has changed the gear ratio to slightly taller than it was originally. At 240km/h(150Mp/h) the car is almost at 6000rpm. It seams to still have plenty of go left in it at that speed. The engine redlines at 7000rpm which suggests to me that the gear ratio is a bit high for quarter mile drags. Only been once pulling high 13's. Was wonderin if anyone knew the standard diff ratio of an N/A 86.5 supra and if they can be changed without too much hassle.
