nope - he wont be talking about that... thats like a diamond compared to the thrust washer inside the R154.. when doing violent changes it apparently ends up slamming into other bits shattering it.

have a read here.... http://turbosupras.com/pages/en/pages/t ... l/R154.htm

heard the best thing is to get one from toyota and have a better one made from a more durable metal (cant rememebr which metal that was tho )


Used to be a thrust washer inside a R154

Anyone else have experience with this gearbox?

We used to run them in the Levin behind the 2JZGTE race car.

Never had problems with that particular part though.

However they were not the most reliable box either.

We now use a hollenger, ( bit expensive for the average person, but it's worth it.)

Hey Matt, What other problems did you have with r154s?

[atmosports]

Could you use a Torrington Style, Needle roller Thrust bearing instead of a washer??? Fitted heaps of them in other applications instead of thrust washers including gearboxs, rocket assemblies etc, not a always cheap option & don't know how effective it'd be either in your application.

Else you could try getting one remanufactured in a different material or with a different heat treatment. Perhaps 2767 high tensile/high toughness steel or similar & then getting it hardened & tempered.

Have a search around the new Toymods forum, http://www.toymods.net/forums/index.php
Was discussed there recently, if you can't find it there were details on the old forum which you can find the link for there.

We had shift lever and fork problems and sorts.

They ended up getting custom made solid brass shift forks made for inside the box's. (they had 3 box's in total, 1 in car, 1 spare, and one was always under repair as parts were so hard to get for them.)

The easiest fix for this weakness is to lighten up on the gearbox and treat it with respect. For gearbox owners with less self-control, the best option is to have the gearbox broken down and reassembled with a new thrust washer made of chromoly for added strength.

i should have read the whole thread first, oh well no matter its here for those who cant be bothered following the links
