The VR4 and GSR gearbox share most of the same gear ratios believe it or not. However the drop in first gear ratio is why the VR4 gearbox isnt really suited for performance applications as its slower off the mark and purposely made to pull a heavier car up to speed (although some people prefer the lower ratio for less wheel spin on take off e.g. FWD's, or people having difficulty getting power to the ground on high RPM take off).
Here is a comparison...
VR4 - 2.846; 1.684 (2nd); 1.115 (3rd); 0.833 (4th); 0.666 (5th); 3.166 (Reverse); 3.866 (Front Diff); 4.933 (Final)
GSR (W5M33) - 2.916; 1.684 (2nd); 1.115 (3rd); 0.833 (4th); 0.666 (5th); 3.166 (Reverse); 4.933 (Final)
Also GSR (W5M33) - Transfer 1.090; Final Front 3.8666 (or 2.936); Final Rear 4.9333 (or 4.525) Brackets may denote Aus-spec.. gotta check it.
I think this explains it well...
Going to a lower (numerically higher) gear will increase your RPMs at a given speed but improve your off the line performance. A higher (numerically lower) gear will get you off the line slower but keep your RPMs lower at a given speed.
Changing your tires will also affect the "effective" gear ratio. A taller tyre/wheel combo than stock will have the effect of going to a higher gear i.e. 17" rims. A lower gear counteracts the taller tyre/wheel combo to a degree. Ever wondered why drag cars have such high profile tyres? Wink
Easy way to remember: High number, high RPMs, high "kick". Low number, low RPMs, low "kick".

EVO 1-3 gearbox ratios below:
The gear ratios are on lancerregister.com under 'evo 1-3 buyers guide'
Here they are anyway:
Evo1:
2.571 (1st)
1.600
1.160
0.862
0.617 (5th)
Rear diff: 3.909
Evo 2-3: (Evo 3 has slightly different transfer and front diff ratio)
2.750 (1st)
1.684
1.160
0.862
0.617 (5th)
Rear diff: 3.909
Gsr: (CD5A)
2.917 (1st)
1.684
1.115
0.833
0.666 (5th)
Rear diff: 3.545
I have also got some info on EVO/GSR/VR4 diff and transfer case ratios below which I got from NZMMC but not sure if they are correct:
VR4s and GSRs:
1.090 Transfer ratio (TR) (24/22)
3.867 (58/15) front diff ratio. (FDR)
3.545 (39/11) Rear diff ratio (RDR)
RDR x TR = 3.868 combined rear final drive
Total final Drive ratio TFD of 4.9333
EVO 1 and 2s:
1.090 (24/22) TR
4.266 (64/15) FDR
3.909 (43/11) RDR
RDR x TR 1.090 (24/22) = 4.264 combined rear final drive
TFD = 5.443
EVO 3
1.074 TR (29/27)
4.200 (63/15) FRD
3.909 (43/11) RDR
RDR x TR = 4.199 combined rear final drive.
TFD = 5.358
The total final drive TFD, is the diff ratio (front or rear+transfer) multiplied by the 37/29 (1.276) primary reduction inside the gearbox that occurs before the diffs.
Contrary to belief, converting one of these 4WD 'boxes to FWD will NOT change the final drive ratio, why the hell would it?
"and yes an evo 2 gearbox and evo 3 rear diff would work together using either the evo 2 or gsr transfer case"
BATTLE OF THE FWD GEARBOXES
Proton Satria 1300cc: 3.363; 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.777 (5th)
Proton Satria 1500cc: 3.363; 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.777 (5th)
Proton Satria 1600cc/ Cyborg MIVEC CA4A/ CJ4A: 3.083; 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.756 (5th); 4.592 (final)
Proton Satria GTi / M21 1800cc DOHC: 3.083; 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.777 (5th) - Code F5M222VRXE
Mitsu CC Lancer 1500cc Carburettor: 3.363 (1st); 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.777 (5th); 4.021 (Final); 3.083 (Reverse)
Mitsu CC Lancer 1800cc MPI: 3.363 (1st); 1.947 (2nd); 1.285 (3rd); 0.939 (4th); 0.777 (5th); 4.021 (Final); 3.083 (Reverse)
At 100kmh revs should be about 3100rpm. The difference could be tyre size.
Cyborg MIVEC CJ4A: 3.071 (1st); 1.947 (2nd); 1.379 (3rd); 1.030 (4th); 0.767 (5th); 4.625 (final); 3.363 (Reverse)
At 100kmh your revs should be about 3160rpm (slightly higher due to higher final drive ratio) - This gearbox has different ratios throughout compared to others (except all 2nd gears are the same) - This one is made for pure acceleration provided you can get power to the ground
A CYBORG RS CJ4A with an ATS Final Drive Ratio of 5.000 will rev at 3416rpm at 100kmh. This gives quicker acceleration but lower top speed.
The top speed for a CJ4A is theoretically 237.32kmh.
With the ATS 5.00 ratio theoretical top speed is 215.86kmh.
A good info i pick up from a local forum . good useful info to share with you all . happy reading
