Question -i don't understand how gear ratios work, but which boxes hit 100 or more kph in 2nd gear? i hate my s53 where first gear is to 50 and 2nd gear is to 90kph. A - You are lucky, the JDM boxes are even shorter Easiest solution is to fit way bigger rims/tyres or contact TRD and replace your final drive (diff) ratio I'm looking for a list of all "S" ratios - anybody seen one? Here's some ratios for the "E" series boxes - "S" is similar but expect differences Ratios: (Japan spec) 1st 2nd 3rd 4th 5th Reverse Final Drive ST165 3.583 2.045 1.333 0.972 0.731 3.583 4.285 ST185 3.384 1.913 1.333 0.972 0.731 3.545 4.285 ST185 RC 3.583 2.045 1.333 0.972 0.731 3.545 3.933 ST185 Rally 3.230 2.142 1.518 1.258 0.731 3.545 4.285 ST205 3.384 1.913 1.258 0.918 0.731 3.545 4.285 MR2 Turbo 3.230 1.913 1.258 0.918 0.731 3.545 4.285 The best way to find the ratios is to count the teeth on each gear and divide the two to get the ratio On my JDM S53 box it is as follows: 1st - 14/46 = 3,286 2nd - 24/49 = 2,041 3rd - 31/41 = 1,323 4th - 35/36 = 1,028 5th - 39/32 = 0.820 Diff - 17/71 = 4,176 At this stage I know the S54 5th ratio is the same and suspect it has a 3.9??? diff, it may be possible the other gears are the same as well - judging by the similarities in the GT4 boxes. So to summarize - the GE has a longer 1st, 2nd, 3rd than the GTE's but the GTE has a longer 4th and 5th gear ST185 RC is the fastest in reverse and has the highest top speed of all boxes.
thanks stig, i don't know much about ratios so for your jdm s53, how does that translate into kph@redline per gear?
I know that the current S54 does 100ks in 2nd (just tried it), so the JDM S53 does around 90k's (check with Fernando) My old box (S53) did 100ks in 5th at 3200rpm, new one is 2800rpm at 100ks
yes kevin you are correct mine also does around 90k's at 6500 rpm in second and 5th at 3000 rpm get 100km and 180km +- 5500rpm I noticed the higher in kmp the better it become's I am happy with this gearbox ratio not sure what it is yet will soon find-out when I remove the motor and gearbox.
It's the normal JDM, I've opened 3 and all were 1st - 14/46 = 3,286 2nd - 24/49 = 2,041 3rd - 31/41 = 1,323 4th - 35/36 = 1,028 5th - 39/32 = 0.820 Diff - 17/71 = 4,176 I think the O/S cars got a 3.9 diff with the same gearing. JDM S54 uses a 3.9 diff too with what could be the same gearing. (5th is identical) I'd like to open a late Camry box and see Here's my S54
just looked at this again, my FE/5sp did 100km at 2800rpm as well... did FE's come with s54 and GE's s53? seems like it for usdm cars...
As far as I can tell the only difference between the S53 - S54 is the bellhousing and starter. Different regions get different gearing as well as FE/GE gearing differences. It seems that in 94/5 the S54 was updated to dual syncros but I'm at a loss to find anything on the LSD versions. Looks like all auto's had the same final drive (3.7)
