Ok, money wise i think it would have been much better going a F5M33... here is some info anyway from a very knowledgeable person from the other mitsubishi forums. He is helping me build up a box for the car.
GEARBOX RATIOS EXPLAINED(finally found it after months it has been missing from the forum. For some reason the search couldnt find this earlier version from September 2004, so I've reposted all the good bits below )
AWD GALANT VR4 and GSR LANCER RATIOS: The VR4 and GSR gearbox share some of the same gear ratios believe it or not except for first and final gear. Look at the difference between the 'final' ratios (number of times the motor needs to turn [driveshaft turns] in order to make the axle/wheels do one full rotation).
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). The final drive for the VR4 is basically for cruising around at low revs at speed.
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); 4.9333 (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; 3.866 (Front Diff); 4.9333 (Final)
VR4 transfer case input spline count = 22 (You will need a 1.090 VR4 transfer case when using a VR4 gearbox as its the only transfer case to suit the gearbox output shaft's spline count)
GSR transfer case input spline count = 23 (You can mix and match a GSR gearbox with a GSR or EVO I-II 1.090 transfer case only)
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".
CD5A LANCER GSR RSIt is apparent that the CD5A 92-95 "LANCER GSR RS 1.8 AWD" was optioned from factory with a viscous and a mechanical 3.545 rear LSD. One of my friends in NZ just checked an import Lancer GSR which has one of the rare factory optioned NRWE front viscous LSD gearboxes in it and upon inspection of the rear diff he confirmed that it has a 3.545 mechancial rear LSD centre. He also did some more searching and apparently the part number for the LSD plates was actually used in some CD5As and CC4A Mirages, so it can be established that the CD5A LANCER GSR RS's did have both a viscous and mechancial rear LSD as an option from factory and are very rare. NOTE: not to be confused that it was an option on EVO 1-3's as discussed below.
_________________________________________________
EVO I-III RATIOS:Info I've gathered and discovered over time and summarised below.
TRANSFER CASES:
* VR4 gearbox + VR4 transfer case input spline count = 22 (You will need a 1.090 VR4 transfer case when using a VR4 gearbox as its the only transfer case to suit the gearbox output shaft's spline count) = 3.545 rear diff ratio result. NOTE: VR4 EVO have a 23 spline count therefore refer to below GSR stats.
* GSR gearbox + GSR transfer case input spline count = 23 (You can mix and match a GSR gearbox with a GSR or EVO I-II 1.090 transfer case only) = 3.545 rear diff ratio result
* EVO I-II gearbox + EVO I-II transfer case input spline count= 23 (You can mix and match EVO I-II gearbox with GSR or EVO I-II 1.090 transfer cases only) = 3.909 rear diff ratio result
* EVO III gearbox + EVO III transfer case input spline count = 23 (You MUST USE the EVO III 1.074 transfer case with the EVO III gearbox only as it corrects the ratio to accept a 3.909 rear diff) = 3.909 rear diff ratio result
REAR DIFFS:
* First thing's first. All EVO I-III rear diff ratios are 3.909. All EVO I-III RS/GSR had a rear mechancial LSD diff centre, except the EVO 1 GSR which had a viscious LSD rear centre with different length rear driveshaft cups and shafts.
* If you are using an EVO III gearbox, YOU MUST also use an EVO III transfer case to correct the rear ratio to 3.909 - this will suit any of the EVO I-III 3.909 rear diffs.
* To make an EVO rear mech LSD a ratio of 3.545 to suit a E39A Galant VR4 or GSR 3.545 gearbox - Simply keep your existing GSR or VR4 rear diff housing, remove the diff centre and remove the 3.545 crown wheel and pinion from it. Get an EVO rear mech LSD centre, and transfer your 3.545 crown wheel and pinion into it. The replaced parts will NEED to be done by a professional as they need to setup the backlash and tooth contact correctly. If its a tiny bit off you're screwed. This can then go back into your existing housing and your existing axles can plug straight in.
__________________________________________________
The gear ratios are on lancerregister.com under 'evo 1-3 buyers guide'
Here they are anyway:
EVO I:
2.571 (1st)
1.600
1.160
0.862
0.617 (5th)
Rear diff: 3.909
EVO II-III: (EVO III 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
EVO I-III gearbox ratios etc:
1st & 5th use the same single piece syncros
2nd gear uses the same double (3 piece) syncro
3rd & 4th on Evo 1 box use single syncros. (same P/N as 5th gear syncro)
3rd & 4th on Evo 2/3 box use double syncros & these will NOT fit a vr4, GSR, or Evo 1 gearbox without machine work to the gears.
Evo 1 has taller 1st & 2nd gear resulting in closer ratio gears especially 2nd-3rd gap
Evo 2/3 however have double syncros & a stronger hub on 3rd & 4th gear
Evo 3 box has exact same gear ratios & syncros as Evo 2 but with a slightly taller final drive & different transfer ratio which requires the Evo 3 transfer case to correct it for 3.909. EVO3 = 63 teeth crownwheel and 15 tooth output pinion, mated to a 1.074 transfer case which corrects the rear diff ratio to 3.909.
EVO 2/3 boxes are same internally. The only difference is EVO2 uses same front diff ratio as EVO1 being 64 tooth crownwheel with 15 tooth output pinion (4.264) for use with 1.090 transfer case ratio = 3.909 rear diff ratio.
A smaller number for gear ratio, (Like Evo 1 1st & 2nd) means they are taller: Less torque at the wheels but more speed for a given rpm.
A larger number (Evo final drive) means it is shorter: More torque to the wheels but less speed for a given rpm.
Power at the wheels does not change significantly with different gear ratios
I have also got some info on EVO/GSR/VR4 diff and transfer case ratios below which I got from NZ MMC:
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 = 3.866 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"

Just re-posting some info that was lost in the great crash of '04/'05 below.
Evo 1 RS: WQYE, 3.909 ratio, no front lsd.
Evo 2: WPGE, 3.909 ratio, no front lsd.
Evo 2: WPWE, 3.909 ratio, viscous front lsd.
Evo 3: UPYE, 3.909 ratio, no front lsd.
Gsr: NRBE, 3.545 ratio, no front lsd.
Gsr: NRWE, 3.545 ratio, viscous front lsd.
Libero/Gsr: NQBE, 3.545 ratio, no front lsd.
I've had in pieces three different types of CD5A/CD5W Gsr/Libero gearbox and thought the differences may be of interest.
GSR NRBE, 3.545 ratio, no front lsd.
These gearboxes have what are know as 'paper' syncros on 2nd and 3rd gear, rather than the regular brass. These are very sensitive to oil type and will crunch badly with the wrong oil.
I've found Redline MTL works well but only once its fully warmed up.
GSR NRWE, 3.545 ratio, viscous front lsd.
These gearboxes have a 4 spider, viscous front lsd diff. The crownwheel is different too, so just having the lsd diff by itself is useless. They also require the use of the longer drivers side inner cv joint.
2nd gear is a double syncro unit identical to those found in Evo 2-3's
3rd gear syncro is a regular brass unit.
3rd and 4th gear use a larger hub and syncros than other 'boxes, its the same size as the 1st-2nd hub!
Because of this, Evo 3rd-4th shift forks WILL NOT FIT THESE GEARBOXES. The Evo 1st-2nd fork will still fit however.
Ive had a NRWE apart before. They don't have steel shift forks, and the ratios of all the gears is the same as regular GSR. As stated before, they do have a front viscous LSD.
Another difference is that they don't use 'paper' syncros on 2nd and 3rd like the more common NRBE variation, but rather all brass syncros with a double syncro setup on 2nd gear. 2nd gear is actually the exact same ratio and syncro as evo 2-3s.
Since NRWE use all regular brass syncros, and the viscous LSDs have their own sealed silicone oils, you can use just about any good gear oil.
Its the NRBE gsr 'boxes you have to be careful with oil selection. Most of these NRBE gearboxes are using the wrong type of oil for their 'paper' syncros on 2nd and 3rd gear causing crunching and people curse their supposedly f**ked syncros.
LIBERO NQBE, 3.545 ratio, no front lsd.
Found in GT Liberos, (and probably others) these are EXACTLY the same as the NRWE described in detail above, EXCEPT that they don't have a front lsd.

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.

The GS-T Eclipse's ratios are totally different to any of the other Mitsu AWD or FWD specs above and interesting to see the first gear 3.09 slightly higher than the M21/GTi/Satria 1600/MIVEC boxes 3.08.. the rest of the gears 2nd through to 5th are lower than the rest of the FWD boxes. This would make it the strongest and 'best of both worlds' FWD (not AWD) box I have seen so far (determined by ratios) except for first the gear... but the difference in 1st gear is so small a difference its virtually negligible. The GS-T's final drive ratio is about in the medium of all the others as well giving this box a nice spread over all the FWD boxes thus far. Will have to see what rpm/speed per gear stats it generates versus a converted AWD VR4 box and stock FWD GLXi box

FWD GEARBOX COMPARISON IN PRACTICE
OK, for those who like to see numbers I have ran 7 calcs on the FWD boxes at max RPM @ 7000rpm with 215/40/17 wheels. The speed/rpm is not perfectly accurate, but all the info from each gearbox was entered using the same calculation method so the comparison against eachother is accurate to see roughly how different they perform to one another. Pics here:
http://orion2001.gallery.netspace.net.au/FWD-RATIOSI have put 5 out of the 7 boxes below for comparison. Stock 1.8, VR4 AWD/FWD, Eclipse GS-T, and CA4A Mivec Cybog, and TN Magna! .
Found out the Hyundai Sonata gearbox is a KM210 - Yep, the same FWD gearbox used on the TN-TP Magnas!
TN Magna 2600cc KM210 gearbox: 3.166; 1.833 (2nd); 1.240 (3rd); 0.896 (4th); 0.666 (5th); 3.166 (Reverse); 1.192 (transfer gear); 3.411 (final)
