you guys are making me feel a little better about the problem. I was looking through my hyper rev mag, and in the drivetrain section, under gears. Two companies sell what looks to be after market stacks. The companies were Jspeed and TSS. I cant read the mag cause of translation but.....theres a shop in chicago where the owner can get anything out of japan. So im gunna call him up make sure these are what i think they are get some prices. Kind of a long shot, but im curious none the less.

 

People keep talking about upgraded gears but I have yet to see upgraded 6spd gears, only 5spd.

 

Maybe that's because you don't speak/read Japanese.


Interested to hear about these upgraded stacks.

 

He said he couldn't either so how does he know it's a 6spd upgrade?

 

I was just playing around. I have no
idea either. The Power Enterprise link is also in Japanese. Babelfish anyone?

 

The Power Enterprise is 5spd "1st 2nd 3rd 4th 5th"

 

do we have any 4th gear failure of 05 MR that did not use BG II ? was it gear oil + heat related?

 

The Power Enterprise Evo kit is for a 5MT. I suspect that someone will eventually come out with upgraded gears though. The kit will surely be big $$$.

 

i haven't seen one, thats the thing. i'd love to know if there was.

 

05 MR on OEM fluid (although I did use BG for about 300 miles before going back to OEM). Fried the 4th gear sleeve and fork on the track, driver error may have been factor.

 

Btw, I've been using a cocktail of approx 1.9qts MT-90 and approx .4 or so qts of Heavy Shockproof for the last 500miles and the trans feels better than ever. Very smooth (when warmed up) and the sound has decreased a bunch as well.

We'll see how my temps are at thunderhill this friday.

 

has anybody tried the redline recommended 1xMT90+2xMTL mix?

 

MTL sucks for our trans. It doesn't have the right ratings (70w80 I believe) and it felt like uber shiat in my car. I would run straight MT-90 over any MTL cocktail. As soon as I put the above cocktail in the car the trans felt 100x better and the whine got much less.
