Gtr Gearbox

[kurt2430]

Hi,

I'm looking at purchasing a GTR for track duties, hill climbs etc . I was wondering how do the gearboxes cope with being tracked.

Should a gearset be installed or are they fine the way they are?

Any information would be greatley appreciated.

Regards,

Kurt

At 300kw you should be fine, at 400kw you'll probably strip third gear (just guessing the power figures, but you get the idea)

yeah I agree. I have been running mine hard for 5 years on the same gearbox, under 300kw though. Includes standing starts and lots of flat shits.

However...I did buy a new gearbox at the start (not sure if they are available any more, if not they can be fully rebuilt). It was definately worth it, any 20yo gearbox will have stuffed synchros and bad bearings.

There is also something in technique (wish I could tell the difference lol), some people just kill these boxes more often in race use.

If you are running over 300kw forget it....just put a ppg or par straight cut dog gearset in it. do not bother with the os giken (or any other) helical stuff for track use with decent power
