There are only 3 or 4 known 6 speed failures, all of them from having much more power than stock and off course drag racing and participating in other racing events. It is logical to think that perhaps any transmision subject to abusive driving might fail.

The MR transmission is very good from the factory. There is a 9 sec Evo 8 MR car with stock tranny and cusco transfer case. They are no worst than any other transmision.

If you were to compite a Evo 5 speed and a Evo 6 speed in a 1/8 mile or half of mile you wouldn't think the MR 6 speed is bad.

The smack talk on the 6 speed tranny comes from having to cross the 1/4 mile drag racing often in fifth (only if you have mods), if you don't have mods on the car perhaps the MR edition is quicker.

I am still amaized about how people uses the 1/4 mile reference to imply that a 5 speed gives you an advantage in the 1/4 mile.

It happens that coincidently there is a window of speed/rpm/gear in which typically a Evo MR will follow when crossing the 1/4 mile line. A bone stock Evo 6 speed has no disavantage over the 5 speed compiting in a 1/4 mile event .

I am very hesitant to believe Mitsubishi Racing engineers would downgrade a transmision for no reason.

To fairly make a comparisson on transmision failure you would have to know how many MR (6 speeds) were made, then how many Evos with 5 speed were made.
Then see and judge case by case base on mods and type of driving.

So far all we heard is John Shepperd transmission and Team rip talking about the 5 speed being stronger but had anyone even put the real statistics together before we claim which one is better?

Carlos, the 6spd _IS_ weak, but only gears 4-6, which most people will never hurt. It has a fundamental flaw due to its tiny teeth on the small 4th-6th gears, but most people will never know the difference. You can drag race this thing and not really ever worry about gears 1-3, so most people will never break it. It's the road racers that overheat the fluid and cause enough friction to rip the teeth off 4th mainly.

 

Clayton,


Ironically you, me and Scott(TTP) had raced the MR at the drag strip more times than average and we had different failures(my 6th gear wouldn't engage due to partially bent forks).
I knew the 1 through 3 on the MR are stronger and that is perhaps why it hasn' failed on me yet.. I have been following the topics related to the 6 speed. I heard that the heating issues when road racing also.

I still think the failure porcentage is so minimal that is not even fair in my opinion to consider it a faulty/handicaped transmision .

At the end of the day look who had failures: You, me, and Scott(TTP) , we all have significant power upgrades and we all compited in many events specially you.

Another thing to mention, have you guys noticed how much bigger the 6 speed gearbox is in size?

Nobody is whining.. I just want to hear some ppl out.. and for those that dnt like my thread.. dnt post.. move on.. I hear you Tony.. I jst wanted an opinon out of the evo808 forums.. because apperantly that is the image of the MR..

Of course the evo was rally bred.. but the purpose you give it its up to you REGARDLESS of what it was engineered for.. the samething can be said about any vehicle.. is a 4dr Honda DX meant for drag.. "NO" but ppl dump money and go stupid fast.. nothing wrong in that..!

Thank you warrtalon and the others who gave a significant input..

I ask the mods to please close this thread.. I am in an island in which there isn't much experience in our forums.. so i jst wanted some views from others that is all..

 

Sorry I wasn't trying to start WW3 about the whole Gsr vs. MR subject. I was just wondering.

 

all evo's are slow.....how bout that one.

 

Yeah man its all good.. him and I are friends.. we dnt even have lil rivalry.. am in the army and so is he.. same company.. same platoon.. we got same job.. just different responsabilities.. and we went to Iraq together so its.. cool.. its just that I never thought it was true.. that MR's are slow but then again I understand the tranny weight issue and its all good..

But still.. I guess i can give him a run for his money.. There are like 4 evos alone in my company and he claimed to be the fastest in the company.. so I was wondering why he didn't even acknowledge me.. as a contender.. so i asked him and he said that MR's are slow.. and also mention why aren't none of them in the low 1/4.. so i was uhmm.. let me see what peeps have to say in the mainland.. Afterall we got the same engine and mine is a bit more modded than him..

As far as my tune goes.. yes tony were both agressive but for some odd reason my MR likes it.. 2 counts of knock on my logs.. as far as my A/F I dnt know.. hopefully just a bit under 12:1 just guessing from my knock count.. but i'll find out.. Mark has a flash on his MR.. from some GSR and he was rich.. but marks was even more richer.. maybe its a MR thing..

 

 

If you wanted the fastest stock EVO for the 1/4, the RS was the best bet. Tests show they're faster by 3 of 4/10th's... I was able to dip into the 12's with an RS, but not with the MR. Both 2006 IX! C&D tested all 3 (2005's anyway)...
The RS is a very raw car.

What the hell, avatar say I'm a newbie, been here a while, I just rarely post!

 

No, RSs are not faster by 3 or 4 tenths. Not sure where you got such crazy information. An RS only weighs 55lbs less than a base GSR. That's good for HALF a tenth. An MR only weighs 68lbs more than an RS, which is still less than a tenth. The heaviest of all is the GSR w/SSL, but that's still just 110lbs heavier than the RS. There is no reason to think an MR is slower - it simply is not slower until you overrun 4th gear, but then the same goes for the IX 5spd, because it's 4th gear is almost identical.

 

damn tony! you're only running 12.5 with nearly 360whp?

 

^ He's not talking about me... my numbers are in my sig man. He's talking about one of our boys out here.

 

I don't know which MRs you're riding in, but I rode in Cletus323's bone stocker and the thing pulled like a freighttrain right off the dig. Felt good to me.

As for ride quality, the MR has a wonderful ride quality to it; less brash than the STi/STI or the GSR/IX, and it handles better. Just because a ride is stiff doesn't mean that it handles well. There are plenty of cars that have stiff rides and are not set up nicely. They're either undersprung and overdamped or vice-versa. The MR is a nice happy medium. I really like the MR's setup.

 

I'm just going by the fact I dragged both cars. I couldn't get the MR into the 12's no matter what I tried. The RS I did. Also C&D tested the 2005s and rated teh RS @ 4.3 secs compared to 4.5 & 4.6 seconds.. 13.1 quarter compared to 13.4 & 13.5 Evo MR and Evo IX ... I just know what I drive with the cars, and the RS is the victor. Maybe it's the wing on the that slows it down

 

Whom ever was driving the car sucks *** and need more practice on the strip.
