I had a junk six speed the input shaft bearing kept going out but typically it's the 4th gear. Same case as five speed with extra gear and parts which over heats it and cooks it from the inside. Most of the time but not always its around the 400whp mark people start seeing issues. I was at 360whp but some are more lucky lol. Five speed swap and smiling :)

Wouldn't a trans cooler help with keeping the trans alive longer? Also anyone have any info on the fq400 6 speed trained compared to the usdm 6 speed trans?

Theoretically, yes.
:confused:

I don't think Ralliart UK touched the transmissions.

What makes you want to keep the 6 speed? Just curious. I just hate knowing I have a "cap" for horsepower because my tranny is holding me back. I loved my 6 speed but I certainly wouldn't go back lol

I have driven plenty of 5 speed evos I know the trans can hold more power, but the trans shifting feels like crap, and can't compare to the 6 speeds shifting. Also I love to mod my car, plus I got the 05 MR knowing they only made about a 1000 of them, I just like to know I'm keeping it an MR still, and if I didnt really want a My MR I would of just got a regular 5 speed EVO. So think I'm going to show the doubtful what the 6 speed can really do.

I hope my 6 speed holds up in the long run

6spd 4 life here lol

I'll try to post pics of what I've done to mine tomorrow.
MFactory 4.00fd, spray bar with direct oiling on gears 3-6, Tilton electric pump and oil cooler. It isn't finished but will be soon.

400/400 on mine but I don't track my car

For the people asking about the FQ400...I'm pretty sure that's 400hp at the crank which translates to I'm guessing less than 350whp which isn't too high. So that's probably why the stock 6 speed would still be fine in that model

I have an 05 MR that I just got. Running about 340/350 whp and its at 80k miles with no problems. I also went to the drag strip once so far but did great. I Do not auto-x.

On one thought tho i do remember an occasional grind in 4th. But it rarely happens

Keep me updated on this, and maybe show me some pics of how you sent things up.

I have taken mine to the strip a good bit and it seems I get locked out in a gear I have a twin disk in mine I can't wait to get a 5 speed

470whp & 380Tq dynojet 6speed:beer:

I have an exedy twin in mine aswell, and never have had any lock out, with shifting at 8000 RPM's aswell.
