Having been involved with this innovative gear kit from its early inception, and then fitting and testing the very first kit to our own shop vehicle CPL Racing can confirm that this gear kit makes an outstanding addition to owners of any K20 powered vehicle who are looking for serious performance and reliability.ĬPL Racing has successfully interfaced the gear kit with the highly popular Hondata engine management systems as well as other engine management systems to allow near seamless full throttle shifts. There is also the choice of a helical gear set for road and track day applications, and the gear kit comes supplied with a floor mounted gear lever and gearshift cable.Īn LED digital gear position indicator is also available as an optional cost extra.ĬPL Racing are please to offer Quaife’s newly released sequential gear kit for Honda K20 powered vehicles. Wide straight cut (spur) close-ratio gears minimise transmission losses and offer a choice of rally, race or drag race gearing.

Additonally, CPL Racing can offer fitment to Ariel Atom 2 and 3, K20 powered Lotus Elise/Exige and other K20 swap vehicles (including paddle-shift upgrade if required). The main advantage of this layout is that it allows for an easy installation into the EP3, FN2, DC5, FD2 models without extensive additional modifications. The original EP3/FN2/DC5/FD2 bell-housing half is reused, enabling the retention of the Honda clutch, differential, driveshafts and mounting points.

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. The outer gearbox case incorporates an additional support bearing between 4th and 5th gear. The gear kit features a compact, drum style sequential gear change mechanism and an open face dog design to ensure an ultra rapid, positive sequential gearshift that transforms the car’s performance. The gear kit is a direct replacement for the standard six-speed H-pattern Honda transmission.ĭesigned to overcome the performance and road gearing compromises of the stock six-speed synchromesh gearbox, the gear kit 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 track day use. 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 has launched an innovative 5-speed sequential gear kit for the EP3, FN2, DC5 and FD2 versions of the car.
