So put it in perspective, if you have an alloy cased 4 speed and the rest of the car is as light as it can be then it's a heavy box, if you have any other box then it's comparable.Īs for Dave E's box it sounds ideal, all the advantages of the Quaife for half the weight. But it's not that much heavier than the Caterham 6 speed box, it's probably lighter than the standard 5 speed box.

Weight is one problem, alloy cased it's still well over 30kg, thats significantly heavier than the alloy cased 4 speed quaife dog box it replaced on my car. Shift quality is clunky in the paddock but what the hell, drive it slowly and it's OK, drive it competitively and it seems to snick silently into each gear as soon as you even brush the stick. Mines in the original location but shortened to fit under the dash, movement is less than 20mm from neutral to gear selected (and forward and back not an unnatural up and down movement), is that agricultural and long? Don't think so, certainly doesn't feel like it when you're driving. Shift movement is down to stick design, Arnies car has a bit of old stick broken, bent and welded on wherever it'll fit, don't confuse this with a properly designed shift lever. Yes it'll clunk into first gear but thats dog boxes not the sequential. Very clever lateral thinking and in my opinion someone deserves a medal for thinking of this.Īs for shifting, I've not driven a bike engine in a car (but have on a bike of course), but I can't recognise my gearbox in these descriptions. What no one has mentioned is that quaife have put the cylindrical selector barrel in the extension housing with the output shaft running thro the middle - an inspired bit of packaging that makes the box physically only marginally larger than the h pattern box and allows it to fit in the tunnel at all.

In this application there is no room above the selectors so they have moved the barrel back and use it to drive the selectors via rods, exactly the same method used to move the selectors on an H pattern box. On a bike gearbox the barrel is above the selectors and moves the selectors directly. All sequential boxes I have seen use a barrel to move the selectors. But there were no alternatives at the time I bought it so I don't think I've got an axe to grind, if there's something better available now I'll look at it.Īs for Peter's commets about it not being a proper sequential I don't understand this. I think it's a good well made box with some very clever design work. See the Quaife QKE38Z IB5 sequential gearbox in action in this video below.Yes I've got a Quaife sequential box and have had it in the car for 2 years. Heavy duty input shaft available for higher power applications Retains stock Ford IB5 clutch, diff, driveshafts and mounts, Key features of the QKE38Z Ford IB5 five-speed sequential gearkit include:,įive straight-cut, close-ratio gears with motorsport suited final drive ratios, QKE38Z offers a choice of gear ratios sets and seven final drive options suited to motorsport top speed requirementsĪ five-speed H-pattern dog engagement gearkit is also available, which features the same ratios as QKE38Z but fits directly into the original Ford IB5 gearbox casing This enables easy installation of the QKE38Z sequential gearkit into numerous Ford models

This combines with an open face dog design to ensure an ultra-rapid, positive sequential gear shift on QKE38ZĬareful design by Quaife allows the QKE38Z to retain the original IB5 bellhousing half of the transmission casing, plus the stock Ford clutch, differential, driveshafts and mounting points

QKE38Z features a replacement Quaife outer gearbox tailcase which houses five power loss minimising straight-cut, close-ratio gears and a compact, drumstyle sequential gearchange mechanism QKE38Z is a five-speed sequential gearkit for the IB5 gearbox fitted to the Ford Fiesta, Focus, Puma and Ka Mk1 We can build this into a customer supplied gearbox for an additional labour charge

Please note this is a gearkit not a full gearbox
