![]() ![]() I recall seeing the barrel/drum selector in a old ( 60's) ZF racing trans axle apart on the bench at the shop one time - looked like a PITA to work on. John, FWIW, you can clutch-less a shift a h pattern Hewland MK box ( Hewland also offer sequential on the old FT200 design ), the Quaife gear set for the 2000E box was a little more agricultural so I never really tried to clutch-less shift it ( not being critical here, its a good thing because you can't change the gears in situ like you would a trans axle) its light a 40 Lbs ( under 20 kilos) I think they have it worked up for the ford bell housing as well but not 100% sure here. ![]() you end up with a compact 4, or five speed box using Hewland MK gears so you have lots of choices, shifter can be configured for h-pattern or sequential. The one I like is collaboration between TRE ( taylor not toyota) & elite, it uses Staffs, Hewland case/guts and Elite ( not lotus) parts to convert to inline. Lots of food for thought arising from a question about who makes the thingiesīy the way this is a neutral emoticon which raises the question about finding that so special gear with a sequential box where my H shaped gear change has neutrals everywhere ![]() I can imagine that back in the day the drivers swooned over that facility. road or competition isn't the possibility to change, let's say from 4th down to 2nd without having to go through 3rd a big plus? I don't think so with such basic designs like the Quaiffe I think that the attraction for me in the Quaiffe sequential box was that it had 5 or 6 gears!īut I ask this question what are the advantages of a sequential change?ĭoes sequential automatically mean "clutch-less" gear changes i.e. The old Ford/Lotus 4 speed gearbox really set the standard way back when & even today is still pretty damned good as fat as smoothness & positivity in gear change. Strangely I was only thinking this afternoon, why bother? In any case I don't think that it would fit in the Elan's backbone without modifications. It being some time ago I don't remember properly but I think that the barrel selector was in the gearbox casing & the back & forth motion gear lever slotted into it the other box of bits (whatever it did) was fastened to the side of the casing. Yes it definitely utilized a barrel selector or what I would describe as a cylindrical cam, not being so up to speed on the technology. The "box" you saw might house the barrel and its end of the selector forks. It could be that Quaife is using a barrel selector system as was common in F1 a few years ago (maybe still is). Optional Quaife ATB (QDF21E) and final drive ratio (QRE9E) availableGrUmPyBoDgEr wrote:There appeared to be a relatively large "box" on the side of the gearbox which supplied the clutch gear change "signal" or whatever but in any case the clever bit of gubbins that does all of the gear change, clutch thinking and or mechanical actuation etc.Retains stock Toyota 2ZZ-GE clutch, diff, driveshafts and mounts.Ultra fast sequential gearshift with straight cut, close-ratio gears.Strengthened gear casing and stock mounting points.Key technical features of QKE9E include:. 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 QKE9E offers optimised gearing with a choice of five shorter overall final drives and two sets of close-ratio intermediate gears with a straight cut tooth form. QKE9E utilises the original bellhousing half of the casing, allowing the retention of the Toyota clutch, differential, driveshafts and mounting points. A direct replacement for the standard six-speed H-pattern Toyota transmission, the QKE9E six-speed sequential gearkit 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. The QKE9E six-speed sequential gearkit is purpose designed for the 2ZZ-GE engined Lotus Elise, Toyota MR2 Spyder, Celica and Corolla models, transforming these sportscars’ performance. Please contact our customer services team to place an order. We will only build this kit into a donor gearbox that must be supplied when ordering. Please note that due to the complexity of installation, we do not supply this in kit form. SKU: QKE9E Categories: Gear Kits, Sequential, Sequential kits ![]()
