A high strength 80mm shaft centre design with all alloy casings enables QBE60G to handle up to 375bhp, yet it can be installed into a Mk1 / Mk2 Ford Escort or
Caterham 7 without transmission tunnel modifications.
QBE60G features a modular gear cluster, allowing easier interchangeability of gear ratios and fewer moving parts, while a drum type sequential gearchange system is allied to an open face dog design on both gear and drive disc. This produces a positive, ultra-fast gearshift – an optional Quaife approved ‘intelligent’ semi-automatic paddle shift is also available.
Free running gears are supported by needle roller bearings to ensure a robust geartrain, while a choice of ratios and numerous gear lever position options allows customers a wide scope for optimising QBE60G to suit their individual requirements.
This is a package for the Nissan Silvia with the SR20 DET engine, including bellhousing and input shaft. This kit allows you to retain the standard clutch release system (must be removed from old gearbox). The flange at the rear of the box is a universal flange so some modifications will be required.
Both helical and straight-cut (spur) gears are available on the QBE60G. The former enables the QBE60G to appeal to ‘fast road’ customers where gear noise is a critical issue.
Key features of the QBE60G heavy duty six-speed
sequential gearbox include:-
• Ultra-fast sequential gearchanges
• Numerous gear lever position options
• Direct drive, overdrive or double overdrive
• Over 1000 in use worldwide
