![]() ![]() So the engine is out and has been sent to a K20 specialized builder. Unfortunately at his last track day the engine ingested something it didn't like and played Missile Command with its pistons. There is some similar logic applied to how a sequential is driven.I have a customer here with a K20 swapped Lotus Exige Cup. I know many folks with a lot of power that have tracked for quite a long time on stock or near stock trannies. If you drive these trannies like they owe you something, you'll certainly have a poor experience, IMO. ![]() I've seen folks blow through a stock tranny in no time on very little power and others know how to make a tranny last a reasonable amount of time. In addition, the driver is certainly the biggest factor. The relationship of failed trannies to solid hub clutches is very direct. There are things that we know *help* (yes, just *help*) to enable the tranny last longer- like a sprung hub for instance. There are other gear ratios available than what has been posted that are a bit taller for those of use with better power that will enable 160mph at 8500RPM or so giving us with 9,000+rpm redlines a bit more room yet. Afterall, the stock tranny has a much lower torque rating than this box! Lotus recently switched to an X-trak for the GT4 and finished 1st in class in a competitive 6 hour race in Italy.ĭespite the lower than optimal torque rating, I may give this a try for 2011 season. Paddle shifting the Evora GT4 and left foot braking would be a big step up over right foot braking the Exige. I much prefer left foot braking, so don't want to use the clutch for upshifts or downshifts. I might be in the market for a dogbox or sequential for another application. Our motor has such a wide power band that we don't really need the tight gear ratios. When we broke our 6 speed Kaaz gear set in qualifying at Long Beach, went to a back-up stock 6 speed with stock gears for the race and Tyler thought it was almost better gearing. Thinking to just switch to the 5 speed as seems relatively proven and World Challenge will be equalizing us (with change in boost) to the Mustang anyway. We (LPL Motorsports) haven't been able to get the 6 speed to handle the power no matter what we try. We're grandfathered in for 2011, but will have to cost reduce our Exige program for 2012 WC GTS. They are cost reducing the class, as the Mustangs coming in is the reference car for speed and cost $76K retail, so all cars in the class for 2012 have to be less than <$100K. A six speed H-pattern dog engagement version of this transmission - featuring the same ratios - will also be launched shortly, please contact Quaife Engineering to register your interest using dogbox or sequential will be allowed for the Exige in World Challenge GTS for 2011. A Quaife ATB helical gear limited slip differential, part number QDF21K is also available for Toyota engined Lotus applications, costing £585.00. Carrying part number QKE9E, it’s priced at £3975.00. Quaife’s Toyota engined Elise / Exige sequential gearbox package includes the new transmission housing, gear lever and cable. These design elements enable Quaife to minimise transmission power losses and allow drivers to easily keep the 2ZZ-GE engine working in its power band, while delivering a top speed more suited to the needs of competition. The new optimised gearing features a choice of five shorter overall final drive and two sets of close ratio intermediate gears with a straight cut tooth form. The standard Toyota gearbox uses road orientated gearing so Quaife has heavily revised the gear ratios on the Toyota engined Lotus Elise / Exige sequential gearbox, making them ideal for circuit use. Careful design by Quaife also allows the retention of the original Toyota clutch. ![]() To see the gearbox in race action at Brands Hatch, please click on:-ĭesigned as a direct replacement for the standard six speed H-pattern Toyota transmission, the Quaife six speed sequential gearbox package includes a specially strengthened outer gearbox casing and sequential gearchange mechanism, which features a compact, drum style design for an ultra rapid gear shift. Quaife is delighted to announce that it has developed a six speed sequential gearbox for the 2ZZ-GE Toyota engined Lotus Elise 111R, Elise SC, Exige S2 and 211 models, which transforms these sportscars’ performance.Įxtensively tested on a variety of circuits by Lir Racing of France in a GT4 Lotus 211, Quaife’s six speed sequential package – part number QKE9E- has performed faultlessly throughout 1250 miles of track testing and racing mileage. NEW Toyota 2ZZ-GE engined Lotus Elise / Exige sequential gearbox package I receieved an email from Quaife the other day. ![]()
