The 5-sp cars have a 3.45:1 ratio while the 4sp cars have a 3.73:1 ratio, both look VERY similar.
Confusing matters is the early 4sp cars had different brakes (Girling/Lockheed) and a different sized input flange.
The 'extra' 5sp gear is really a lower first gear to give the impression of an overdrive at top is still 1:1. The Supra 1st gear is lower than the 4sp trans, but almost identical in 2nd, 3rd & 4th.
3.45:1 is a bit tall for a high revving 2.0 car. The hot ticket is a 3.73 RE in a car with either 5sp transmission.
