    Okay I recently mixed some gears on my fwd transmission build and it turned out very successful. I ended up using 1997 1rst and 2nd gear and 1990 3rd and 4th gears the transmission turned out absolutely amazing shift quality was awesome everything was cryo treated , shot peened and wpc treated I have going to start another fwd project later down the road. Now that I have an Awd project I want to do the same thing. I want to use the 1990 3rd and 4th gears in my current 2g Awd transmission. I have been doing a lot of reading and found that there are a few more items to try and match so as to keep all gear ratios matched between transfer case and transmission than the fwd gut swap. The current Awd tranny in the car is 23 spline with matching transfer case and the 1990 unit is 21 spline in which I don't have a transfer case. I will get the numbers off the awd tranny and post them just so that we all know what year 2g awd tranny I have. I know Tim has a lot of information on this for he is the one who let me know exactly what to lookout for on the fwd gut swap. Tim if your input is greatly appreciated. Also let me know what center diff I need to send in to you to have the 4 spider machining done. thank!

    I am wondering do I use the same rebuild kit for the two hole shift fork?

    Take it apart and you will know whats in it. Gear ratios for dsm tranies are the same. Evo isnt. Some important changes are involute of 3rd gear/cctr diff and final drive of front diff from 90-96 vs 97 up.

    " The Evo 1 transmission is different in several ways from either the Evo 2 or Evo 3 transmission internally though and only shares the same final drive (pinion output shaft and ring gear), 5th/Reverse gearset and hub/slider assembly, and a few other parts.

    The Evo 1 does have the tallest 1st gear ratio available from OEM mitsubishi parts for the W5M33 transmission. The Evo 1 1st gear is 2.571:1 ratio, the Evo 2/3 1st gear is 2.751:1 ratio, and the DSM 1st gear is 3.083:1 ratio, and the Galant VR4 1st gear is 2.846:1 ratio. Being that the Evo 1 had such a tall ratio 1st gear, the reverse idler gear lever arm was a different shape to clear the gear, so if you ever find an Evo 1 1st gear/2nd gear/input shaft, you will need to either clearance your DSM or GVR4 rail lever to fit the gear or find an Evo 1 rail lever (nearly impossible).

    The Evo 1 also had solid steel shift forks, and solid steel shift rails/rail ends that were extremely beefy. The downside to the transmission was that it did not come with a shot-peened input shaft or gearset while the Evo 2/3 did have shotpeening work on certain parts done from the manufacturer.

    All Evo 1/2/3 transmissions had options of either an open front differential or a clutch-type LSD front differential. All Evo 1/2/3 transmissions came with a standard 2-spider viscous center differential.

    Unfortunately, the Evo 1 solid steel shift forks and rails are no longer available from Mitsubishi.

    Hopefully this random information is helpful to you or anyone else.

    1. To give you an idea of what the Evo 1 first gear means for insanely tall, here is a breakdown of the DSM 3.545 final drive ratio being used on the following 1st gear options on a 25" diameter tire:

      DSM AWD (3.083)
      2000rpm =14 mph
      3000rpm =20 mph
      4000rpm =27 mph
      5000rpm =34 mph
      6000rpm =41 mph
      7000rpm =48 mph
      8000rpm =54 mph
      9000rpm =61 mph
      10000rpm =68 mph

      Galant VR-4 (2.846) (8.5% taller)
      2000rpm =15 mph
      3000rpm =22 mph
      4000rpm =29 mph
      5000rpm =37 mph
      6000rpm =44 mph
      7000rpm =51 mph
      8000rpm =59 mph
      9000rpm =66 mph
      10000rpm =74 mph

      Evo 2/3 (2.751) (12% taller)
      2000rpm =15 mph
      3000rpm =23 mph
      4000rpm =30 mph
      5000rpm =38 mph
      6000rpm =46 mph
      7000rpm =53 mph
      8000rpm =61 mph
      9000rpm =69 mph
      10000rpm =76 mph

      Evo 1 (2.571) (20% taller)
      2000rpm =16 mph
      3000rpm =24 mph
      4000rpm =33 mph
      5000rpm =41 mph
      6000rpm =49 mph
      7000rpm =57 mph
      8000rpm =65 mph
      9000rpm =73 mph
      10000rpm =82 mph


      The Evo 1 Input shaft, 1st gear and 2nd gear are a matched set. They must be used together as the 2nd gear is 5% taller than a DSM or Evo 2/3 2nd gear.

      The downfall to the stock Evo 1 transmission case is only the lack of shot-peening of parts from the factory, and the lack of double synchros. Other than that, it is a fun transmission because of the tall 1st/2nd, the close-ratio 4% shorter 3rd and 4% shorter 4th, and the 8% taller 5th.

    It sounds like Kel struck gold. You can shot peen those parts easily, and have them machined/modified for double synchros. Or you could get them faceplated.


    Good information Kelvin!

    I was ask to take a picture of the differential where the axles slide in he said a True lsd will be hollow all the way through. tmp_24230-VZM.IMG_20151017_180457-1972998623.jpg

    OK, now just put this together for you for the DSM 1G wink.gif

    1G DSM AWD W5M33-2-NPXV Gearbox code.
    Fitted to 91-94 Eclipse AWD 5spd manufactured between 6/90 - 2/94.
    The 1G AWD manual transmission actually shares the same input and intermediate shafts as our CD5A GSR Lancer's do.
    It actually shares quite a lot the same as our GSR boxes and only difference is a different 1st and 3rd gear cog to the GSR!!
    1st gear = 12/37 = 3.083 (1G specific 37 tooth gear cog which lives on the intermediate shaft).
    2nd gear = 19/32 = 1.684 (same tooth count as GSR and EVO I-III) Note: EVO 1 uses a completely different gear. All are double synchro.
    3rd gear = 25/29 = 1.160 (same tooth count as EVO I-III) Note: But EVO II-III use double synchro 3rd gear sets.
    4th gear = 30/25 = 0.8333 (same as GSR) Single synchro.
    5th gear = 33/22 = 0.666 (same as GSR) Single synchro.
    Reverse = 3.166
    1G Front Diff Crownwheel = 58 teeth
    1G output shaft = 15 teeth
    Front Diff Ratio = 58/15 = 3.866
    Output shaft to transfer case = 23 teeth
    Transfer ratio = 1.09
    Rear diff ratio: 3.545 (39/11)

    Here are the DSM gearbox ratios to compare to: http://www.vfaq.com/mods/Trannies.html

    Just found out the transfer case on the car is definitely from a 1995-96 2g 58 tooth ring gear. Once I crack open the transmission I will see of the ring gear has been changed from the jdm tranny to match, from the looks of it I doubt it. This also will be corrected during the bullet proofing of the tranny.

    Some more information gathered from evo forum.

    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

    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"

    Kel I have an evo 1 trans in one of my cars. I thought it was stock until the center diff locked up on the interstate on my way to the shootout last year. It had the 4.26:1 front diff ratio. I was told by the seller it had a gvr4 first gear. The issue with these transmissions is you can no longer get the input shaft so when its toasted the whole transmission is done for.

    My evo 1 is WQNK non lsd. I really hope your center diff is in good shape. There are 3 different style center diffs. 1). 92-99 with a single tab for the lower oiling washer, 2) 90 which has a different oiling washer design and a different outer gear profile, 3) early 91 which has the updated oiling washer (92+) but shares the gear profile with the 90(and my evo 1). I built an extra center diff from a 92+ bc the evo CTD looked like the 92+. When I was assembling the transmission all excited I hit a road block with the CTD bc the gear profile was wrong. I should have welded my extra early 91 ctd (its not rebuild able) but I pulled a mint ctd out of a 90 trans and used it. Tim told me the evo 1 with the 90 ctd gear cut were the early models so your ctd should be 92+. Just trying to give a heads up.

    do you have the passenger side axle for the lsd?

    the lsd axle is about 1/2 inch longer.

    transfer cases are the same, just a 91-96 case for the evo 1-2 and 97-99 for the e3

    or just swap the 90 shaft and use the 90 t case if you have one

    your going to swap in dsm final drive im assuming?

    i did this exact swap 5 yrs ago
    evo 1 trans no lsd tho

    that tall first was incredible!
    but i was in a colt with 23 inch tires and 2550 lbs
    might be a bit tall for a 3000 lb car

    i have an evo3 lsd box in my colt and its the best mod ever. ive only gone down the strip ten times or so with it but i have yet to miss a shift
    trans is usually the last thing guys upgrade but to me its the most important mod.
    it was always so frustrating missing shifts at the track
    crunch!
    haha
    even the evo first gear makes a huuuge difference because it makes a smaller gap to second as well

    The 2.57 first gear rules in a 1g. I can actually cruise parking lots in first. Its really annoying in parking lots with a standard dsm trans... Run first at 4k rpm or chug around in second. The 8% taller 5 sucks at 55mph tho, its not enough rpm and lugs the motor and I find myself downshifting for hills (8.5:1 cr with 272/272 14b) once you get above 60mph it rocks and its awesome at 70.

    If your trans has the large synchro 3-4 you'll want to toss those parts in the trash, as the large synchro 3-4 uses the 2g style hub/slider that explodes over about 400ft/lbs.

    Thanks guys. this transmission has been in this car for 9 years and was driven from Arizona to Atlanta according to the previous owner he had no idea about it being a evo 1 unit until I texted him LOL. I only pulled it out of the car to change the clutch but decided to go ahead and tear it apart to replace the sychros and have the gears wpc treated in preparation for the 800hp engine. I will try and tear it down today. Thanks for all the heads up for sure!
