How much TQ is the stock 2015 6 speed go for?

QBE69G required for decent VQ torque ....... the 62G is a transaxle box (diff and box in same housing and is used for Ford GT40 replica's and such).

You would have been thinking of the QBE60G which is based on Ford Type 9 casing, and was previously offered for 350Z and now Quaife recommend the QBE69G.

Depending on your objective and budget, you have lots of options.

That said, the OEM Z34 box is fairly stout and will take a lot of abuse, but eventually you will see 5th/6th syncro's wear with a lot of use.

My 09 model gearbox will now often baulk going 5th to 6th at hi-rpm and will need looking at eventually, but I have a Holinger 6-speed available to go in with new Grand-Am spec engine next year.

Getting under 2800lb is fairly simple but involves a completely stripped out car and dropping the creature comforts (HVAC etc).

A few guys down-under are approaching 1200kg (~2650lbs) and that is MAJOR surgery with lots of tin removed and a chrome-moly lightweight cage as well.

If you are serious, talk to Brian at Valkyrie Autosports or one of the other race/fab shops on this forum.
