Solution for Toyota Gearbox Problems

Post by petere » Fri Feb 12, 2010 11:36 pm

It�s a known problem on racetrack for exiges and 211. everybody who has taken apart the gearbox, can see the gearbox is not really build for more than 220 bhp. martin from www.jubu-racing.at constructed together with BMW motorsport supplier a set of stronger gearwheels to solve the problem .

Do these have syncros?
Or does straight cut not have them?

To be honest I don�t know.
Looks like nearly straightcut.
But Martin knows more - aks him, he constructed for month, because his teamcar broke gears several times and no one of the LCE guys had solution for the problem. only dogbox, but its expensive and brings 30kg penalty.

Looking at the photos they are still synchro parts. The cone is a spline fit on the gear.

One thing i didn�t mention:
The teeth of the gearwheels are designed to compensate the relatively high flex of the long and weak shafts. They really thought a lot before designing and producing the parts.
They are not really cheap, but these parts can save a much more expensive gearbox life. So i think its worth to think about it, as i saw lots of tuned exiges fail because of gearbox problems.

Peter

Mine went last year at Spa, lost a half day and had a very noisy time driving home, this is why I am buying them and designing an oil cooler solution as well ;) theirs is just too expensive :(
