QBE91G is a heavy duty six-speed sequential gearbox for the popular Nissan Skyline R32-34 GTR models. Incorporating a Nissan RB26DETT compatible bellhousing and the same 90mm shaft centre design of the proven QBE69G heavy duty gearbox allows the unit to be rated to 750bhp.
Technical highlights include a drum type sequential gearchange system, allied to an open face dog design on both gear and drive disc, producing a positive, ultrafast gearshift. A bespoke rear casing allows the standard Nissan transfer to be fitted, making the QBE91G a direct replacement for the standard box.
Offering a choice of straight-cut (spur) or helical gear ratios (including overdrive options), Quaife allows customers a wide scope for optimising the QBE91G unit to suit their individual requirements.
