Quaife Engineering launches new six speed heavy duty rear wheel drive universal sequential gearbox rated to 750bhp
Specialist British automotive performance transmission manufacturer RT Quaife Engineering Ltd today announces a significant addition to its product range, with the launch of a new heavy duty six speed sequential gearbox designed for endurance racing applications.
In 2008 Quaife’s technicians identified a market opportunity for an upscaled version of the firm’s successful QBE60G inline six speed sequential gearbox, which would be designed to suit higher torque and power output motorsport requirements.
The result of this careful design work is a competitively priced new unit – designated QBE69G – which is rated to power outputs of over 750bhp and features an integral oil pump to ensure adequate lubrication during long distance racing events.
Incorporating the lessons learnt on the popular 60G unit, the new 69G utilises 90mm shaft centres and larger gears to maximise strength, with a well proven modular six speed gear cluster layout.
Quaife’s new QBE69G gearbox offers three choices of gear ratios:

1st 2nd 3rd 4th 5th 6th
2.435 1.858 1.494 1.268 1.116 1.000
2.759 2.050 1.494 1.268 1.116 0.870
2.653 1.745 1.306 1.000 0.850 0.762

Use of the very latest dog engagement tooth profiles in the 69G has resulted in a six speed sequential unit which allows ultra rapid gear changes and not only offers users a choice of gear lever locations, but also the option to upgrade to a state of the art closed loop, pneumatically operated semi automatic paddle shift system.

Quaife’s popular digital gear position indicator is also directly compatible with the new 69G and is available as an optional extra ex-stock.

Initially the 69G gearbox will be offered with a bespoke Dodge Viper pattern bellhousing only, with ‘hybrid’ bellhousings being modified to other applications by Quaife to order. Various input shaft options are also available from Quaife on request to suit customer requirements.

Forward orders are now being taken for the Quaife QBE69G unit, which is competitively priced at £6595.00 excluding VAT.

I've been watching this tranny for sometime now and thought I'd share with the Z34 owners what I received today from Quaife;

Try Holinger Engineering ... a cheaper solution and already well proven in Porsche SuperCup and V8SuperCar racing. Also fitted to some BMW's (M3GTR for instance). The Pom's are just a little bit late and also expensive ...

Sick, I want one! Wonder if it will work for our cars? Someone please find out!

Use of the very latest dog engagement tooth profiles in the 69G has resulted in a six speed sequential unit which allows ultra rapid gear changes and not only offers users a choice of gear lever locations, but also the option to upgrade to a state of the art closed loop, pneumatically operated semi automatic paddle shift system.

The QBE69G gearbox is supplied with a choice of straight cut (spur) or helical gear ratio sets:
Gears: 1st 2nd 3rd 4th 5th 6th

Spur (1:1) 2.435 1.858 1.494 1.268 1.116 1.000

Spur (1:1) 2.759 2.050 1.565

Spur (o/d) 2.435 1.858 1.494 1.217 1.000 0.870

Spur (o/d) 2.759 2.050 1.565

Spur (o/d) 2.211 0.868

Spur (o/d) 0.790

Spur (2o/d) 2.653 1.745 1.306 1.000 0.850 0.762

Helical 2.719 1.994 1.524 1.208 1.000 0.858

Bellhousing options including Dodge Viper and Sierra Cosworth YBT pattern are already available and, in addition, use of an specially designed adaptor plate ensures that the QBE69G is compatible with fitments already offered for Quaife’s smaller QBE60G unit, including the Ford Duratec and Nissan 350Z.

Various input shaft options are also available from Quaife on request to suit customer requirements.

Quaife’s popular digital gear position indicator is also directly compatible with the new 69G and is available as an optional extra, ex-stock.

Forward orders are now being taken for the Quaife QBE69G unit, which is competitively priced at £6595.00 excluding VAT where applicable.

:drool: Let's just say that the possibility is there. :driving:

Yeah but did you see the price? $9,000USD PASS :tiphat: I'll just settle for their LSD's thanks. GL with the purchases.

9K. Rigggght. The stock is defiantly good enough to handle what we throw at it from what I've seen. But whatever floats your boat. I guess this would be for the serious track guy day in day out.

Well for those who do not know, Robert has a TT 350z and recently he lost third gear. Basically buy a new transmission on his own dime, rebuild his current or buy a better one.

Do guys understand what a sequential trans is though!? This isn't a standard six-speed H-patteren transmission. LOL! A sequential can be found on many race cars and all WRC cars. Yes even those with paddle shifts are sequential. And if you have ANY knowledge on Quaife you know they are one of, if not the best in the industry for gearboxes and differentials.

Watch this video to understand a sequential trans;

YouTube - Quaife Fiesta ST150 sequential gearbox roadtest

And as Dreamer said, I recently lost third gear in my Z33 and have been wanting this tranny for a couple years now. Only problem was the original model was rated for 350-400BHP. I have surpassed that a long time ago. LOL Now with this model available being rated for 750+bhp I plan on dropping it in. Doing research on gear sets and talking with Quaife directly about what will be best for my overall build.

Don't get my comments wrong. I'd love to have this but the price is killer for me. If I had a dedicated Race car, I'd want this, but for my DD it's not realistic. If you can do it, WOW that would be awesome.........and I'd want a ride in her. :yum::yum: I had a project car awhile back that I would have loved to use LG Motorsports tranny but that was too pricy for me. I'm sure you searched out gear sets, does anyone offer any for this tranny? If you get this please be sure to post. I'd love to follow your progress. GL with this, I hope you can get it worked out. :tup:

subscribed to see who will pop this into their Z first :D
