Shep only rebuilds them to stock spec. He sold all of the custom gear sets.

The only reason I built mine was to see how far I can push the trans at the Texas Mile again. I was in 6th for over a half mile. With the FD change 5th will top out at 191 and 6th will be 236. My goal is 190+

 

man i wanna see videos of your EVO going, man bet that car is a beast.
Also do you have all upgraded gears/syncros with the custom FD, or are you just better oiling system to the factory gears/syncros that are in the trans?

+1. How does it shift feel compare to stock?

 

I'm still running my 6-sp, but I've also upgraded to the Shep 3-5 gearset. 350/325 on 91; 421/425 on E85. I do not drag race the car, but I do hit the track for lapping whenever I'm around and daily the car when I feel like it.

 

I'm using all factory pieces. I was just going to replace the 4th syncro but after I read the FSM I had to replace the 3/4 hub and slider. Then once I went to order the parts they informed me I have to replace them as a set(3rd syncros, hub/slider and 4th syncro).
I'm not sure if that applies to the 9MR.

Chef-j I'll give you a ride when it is done. It will be a little brutal with the QM but other than that it will feel the same.

 

Thanks everyone for the good info. Gonna be putting a oil cooler on my trans, and trying to do a few other things to keep my trans living long with the good HP I want to put down.

I think if you put an oil cooler and the best trans oil recommended for the 6speed (ask an expert, not randoms on this forum) you stand a good chance of having your trans live through some light duty track use at moderate power. Especially if your tuner is aware of your trans issue and makes a nice smooth torque curve instead of a massive sledgehammer hit of torque.

And even if you do break it, 6spds are rather cheap to come by. A low mileage mint one can be had for something like $600 to $800. And mitsu has all the parts needed to rebuild one as well. Unlike the tcase which only comes as a unit.

 

My 6 speed had ZERO issues in the 3 years/30k that I put on it. Launched under 40x Id say. Never a grind or a peep. That was with 100+autox events and many street pulls. I am in the middle of looking to buy another evo and it will probably be a ix se. The 6 speed is so damn smooth!!!!!!!!!!!!!!

 

I also do think tranny oil cooler will helps alot with 6 spds.

 

Thanks.

Shep said build starts at 780 and should hold 350~400tq with fresh fluid. Humm that im guessing it will be better than normal 6spds?

 

I had 86k miles, been through 2 stock clutches and was on a ACT hdss, 30+ drag launches (not including previous owners), 15 full road course days, etc. It was great, never had a problem. Until one fateful day.....

 

My trans has held 40+psi from my black. Don't ask how much HP/TQ as I don't know or care. I've never tried to see if 6th would take the abuse either but 1-5 has.

 

Thats sounds pretty good to me.

 

I love the devotion. And I agree the 6 speed feels great compared to the notchy 5 speed. Take the road less traveled!

 

I have an 05 ww evo MR 6speed still and it's making 401 whp 368 wtq Corrected on a mustang dyno uncorrected numbers are on my sig and I'm hoping to hit the drag strip this year..any body know the speeds of the gear revving to abt 8k
