ZMANALEX Posted July 25, 2017 Posted July 25, 2017 Well it had to happen eventually. The car is producing 720bhp at the wheels and circa 700 lbs.ft. Used predominantly on track, but still loved and cherished. For those of a technical disposition this is the original box from a 2005 350Z Roadster (28,000 miles) and not the later CD009 transmission with the improved syncros. However the part that failed is shared by all VQ35DE gearboxes. Unfortunately not worth of fixing as the cost of replacing the damaged part (Main Drive Gear) and the marrying counter shaft gear set and upgrading the syncros to CD009 quality would exceed the cost of a new CD009 gearbox from over the pond at less than 2k delivered to my shop.

-G- Posted July 25, 2017 Posted July 25, 2017 Bloody hell Alex! That's a lot of power, little wonder it took out the main drive gear! Have you been unable to find a CD009 in the UK? That would surely be cheaper than getting one stateside? 1 Quote
Redsky Posted July 25, 2017 Posted July 25, 2017 720 at the wheels has got to be close to triple the stock O.O Thats amazing. Kind of annoying how a ton and a half of brilliant work is brought to its knees by a couple of shards of metal deciding to bugger off. 1 Quote
andy james Posted July 25, 2017 Posted July 25, 2017 You have had a good run with that box Alex and I'm hoping my one will soldier on! Thinking the internals of the Zed box was robbed from a truck when designed. Lol 1 Quote

Thinking the internals of the Zed box was robbed from a truck when designed. Lol Providing the syncros do not give up, the early boxes are usually fine. However the 3 teeth that sheered off were central to an oil gallery feed supply hole. And as it was a 1st motion shaft failure (main drive gear) then it has got to be down to the torque. Good luck with your box mate, however I would not envisage that you will have any issues as they are robust albeit a bit agricultural. Quote

That is the trade off in venturing into the realms of circa 700 lbs ft torque. I am fortunate that I can fix these issues and that I have the premises and tools and equipment to deal with such eventualities. I have never seen or heard of a (1st motion shaft) final drive gear failing. Quote

Willsy1980 Posted July 27, 2017 Posted July 27, 2017 Seeing how much it took to break this box, gives me more confidence to give mine a little stick from time to time Quote
evilscorp Posted July 27, 2017 Posted July 27, 2017 Did you get the new box from the Glasgow eBay guy? Seemed like a good price, fortunately my drunken state only let me fling in one bid for it lol. Glad it went to someone deserving :-) Quote

ZMANALEX Posted August 6, 2017 Author Posted August 6, 2017 Just an update, had a 2 hour open pit at Knockhill last night and gearbox and new ceramic twin plate clutch were all good. Quote
