Quaife Sequential Race Gearset
Quaife Engineering has introduced a sequential 5-speed transmission for the K-Series ideal suited to road racing, circuit and drag racing applications, the Quaife QKE8J features wider gears along with an additional housing support bearing between the 4th and 5th gears to increase torque and horsepower capacity.

Responding to requests from numerous customers for a stronger, high performance affordable gearbox solution for the popular Honda Civic Type R, transmission specialist Quaife Engineering is delighted to launch an innovative 5-speed sequential gearkit for the EP3 and FN2 versions of the car (which also fits the grey import Integra DC5 and the US only Acura RS-X and TS-X models.) Carrying part number QKE8J, the gearkit debuted at the Autosport International Show 2013 and is designed as a direct replacement for the standard six-speed H-pattern Honda transmission.
Designed by Quaife to overcome the performance and road gearing compromises of the stock six-speed synchromesh gearbox, the QKE8J gearkit converts the factory Honda transmission into a faster shifting five-speed, dog engagement sequential unit featuring wider, stronger, close-ratio gears, ideally suited to the rigours of circuit racing, drag, rally and trackday use.
QKE8J features a compact, drum style sequential gearchange mechanism and an open face dog design to ensure an ultra rapid, positive sequential gearshift that transforms the car's performance, indeed Quaife has designed QKE8J to be fully compatible with electronic engine management systems to allow for near seamless full throttle 'flatshifting.'
The Quaife QKE8J Honda gearkit features a replacement Quaife outer gearbox case incorporating an additional support bearing between 4th and 5th gear. By comparison, the original Honda design relies on bearing supports located at either end of the gearbox shafts; a potential weak point, particularly for cars running highly tuned K20A engines.
QKE8J re-uses the original EP3/FN2/DC5 bellhousing half of the transmission casing, enabling the retention of the Honda clutch, differential, driveshafts and mounting points. The main advantage of this layout is that it allows for an easy installation into the EP3, FN2, DC-5, Acura RS-X and TS-X models without extensive additional modifications.
Wide straight cut (spur) close-ratio gears minimise transmission losses and offer a choice of rally, race or drag race gearing. There is also the choice of a helical gearset for road and track day applications and the QKE8J Honda sequential gearkit comes supplied with a floor mounted gear lever and gearshift cable.
