Celica ST - C52 Tranny ... 4.311 or 3.722 Final Ratio?? Options

[h4rfang]

hi i have bought a '94 Celica ST with C52 Tranny last year and I am currently changing the input shaft bearings (rear and front) because they were worn and the no.2 shift fork because because it was very worn causing 3rd gear pop-out...

i know the C52 can be found in these cars:

Toyota Celica
Toyota Corolla (E90) GTS
Toyota Starlet GT Turbo
Toyota AW11 MR2
Toyota Corolla Levin AE101 / Toyota Sprinter Trueno AE101 - early years
Geo Prizm (1990-1992)
And maybe more...

apparently all AW11 MR2 have the 4.311 Final ratio and the FWD cars can be found with both ratio: 4.311 and 3.722...

i want to know if the '94 celica have the 4.311 Final Ratio or 3.722 Final Ratio?? and how to know if i really have the 4.311 or 3.722 final ratio???

THANK YOU!

if by ring gear you mean the splines in the engine (or the splines on the tip of the shaft), then that's wrong.

you'll need to find out which of the gears mesh for each gear (1,2,3,4,5,Reverse). in first gear, two gears are in mesh.. one from each gear shaft.(example)

just count the number of teeth from one gear and the number of teeth of the gear in mesh on the second gear shaft.
take the larger number and divide it by the smaller number. that's the gear ratio.
