The difference between Mr And RA tranny

The difference between Mr And RA tranny
What are the specific major differences in the tranny if there are any at all? they are both the sst tranny, so does that mean that for a MR you cannot fit a larger turbo at all while the RA can only go as large as the MR already has? I only ask this because i thought they had the same transmission and if thats true then the same limitations. Im prepared to be flamed by this question!

pretty sure the difference is in the clutch packs. they are beefed up in the MR cuz it has that larger turbo from factory. guys have put bigger turbos on MR cars already but i think they limit the torque to 350 ft lbs electronically. guys have put the stock evo turbos on the ralliarts without too much problems. The guys at AMS tried putting an FP red on a ralliart, but fried the tranny.

ya i wanted to just keep building slowly and i dont want to put a smaller turbo if i could just save up a lil more and get a bigger one for my RA, but it looks like im kind of limited with the tranny and i dont want to harm it, its kind of expensive! lol

i'd say if you really want to make enough power that bolt on's can't provide, do the swap to the EVO turbo. i'm picking one up used with 30xxx kms on it for like $450 CDN. once you've swapped over all the OEM parts to support the evo turbo, down the road, if you want to go up to FP red, then it'll be super easy. This way you can get more power for now, until they make bigger clutch packs for our tranny. i dont know if the clutchpack kits for the evo MR fit our cars or not.
But this is the approach that i'm taking. maybe you wanna just go for the gusto now and not have to do two turbo swaps. but if you put a FP red on your car, i don't think it'll last long. hahah

Works sells the SSP clutch packs which significantly upgrade the SST tranny. The only problem is they are like $3000 just for parts.
From what I have read on this forum, 300-350 ft-lbs of torque is the limit of the SST, any more torque and the discs start slipping.

It's all in your tuning. I believe you can run 400whp as long as you keep it around 320ftlbs of torque and lower. When the bright tuners we have on the forums breaks the ecu logic on all the safeguards, then we can go higher and look into upgraded clutch packs.

i have in the past , done some ( limited ) research on the getrag transmissions.
i could not find proof anywhere .........
.....that they produce two different transmissions for mitsubishi.
from what i had found the getrag transmission fro the MR an RA.......
.....have the same model number.

I've read somewhere before that the 5th and 6th gears on the RA trans is slightly larger, which is made for better highway economy. Other than that, I believe the only other difference is that the MR has S-Sport mode.

Have you guys checked out the Cobb AP maps for EvoX? In its documentation the 1.04v revision of the maps feature a torque monitor defeat. Does it mean that Cobb has a solution for the torque limit on SST, on the MR at least?
