The two gear boxes I have are both early wide ratio Cortina boxes pre 1966. The photo above compares the two shafts out of my spare wreckers gearboxes with the old main shaft from my 1968 Elan gear box which currently has a Quaife gearset in it that was installed in the 1990's I've no experience with Qaife gear sets, but found this thread: It was often the practice to modify the newer style synchro rings to allow the early blocker bars to fit, and to work with the early gearset assemblies. There was a time when new replacement early type synchro rings were hard to find or very expensive. circlip main shaft, synchro rings, blocker bars, synchro hubs, and no doubt more that I've forgotten since it's been a few years since I've been inside one. The synchro rings are just one of several differences snap ring vs. I've rebuilt 6 'boxes - 4 early Cortina types and 2 later ribbed types, and have 2 more and lots of parts waiting for me to get to. i always wanted to get a better idea around the issues of parts interchangeability across the various ages of three rail "2000e" boxes and now is my chance Rohan Rgh0 wrote: The differences in synchro hubs versions is not clear and something I will need to research once I get my 2 old gear boxes fully to bits to understand what is compatible or not with the Quaife gear sets. I would guess "promotor" knows more about this stuff already and will contribute here as he does lots of diffs and gearboxes i always wanted to get a better idea around the issues of parts interchangeability across the various ages of three rail "2000e" boxes and now is my chance The differences in synchro hubs versions is not clear and something I will need to research once I get my 2 old gear boxes fully to bits to understand what is compatible or not with the Quaife gear sets. Yes I need to reuse synchro hubs / change rods and forks from my old boxes to use with the new Quaife gear sets which come with new shafts and all other gear bits needed. Thanks for confirming the Mk1 cortina versus Mk2 cortina bellhousing and thus gearbox as i had suspected it was that based on the pilot bearing spigot diameter difference I'm not 100% sure if they are interchangeable. Main shafts and synchro hubs for example are also different. The later box has quite a few internal improvements compared to the earlier box. The ribbed box is the Mk2 Cortina 2000E type box. The seven-speed Quaife QBE89G in-line gearbox is on sale now, priced at £5695.00 excluding taxes.2cams70 wrote:The non ribbed box is Mk1 Cortina. The QBE89G’s drop gear ratio is: 1.045:1. Quaife’s addition of a pair of interchangeable drop gears within the QBE89G allows users to easily and quickly tailor the overall gearing to suit their needs, for example for fine tuning between racing circuits to optimise top speed or overall acceleration.įrom the outset Quaife’s engineers have designed the QBE89G to run with an optional electronic semi-automatic paddle gearchange system to maximise the transmission’s potential. The QBE89G’s seven forward gears boast ultra-close gear ratios, a modular gear cluster and an open face dog design to ensure rapid gearshifts. For easy installation into a wide variety of front engined, rear wheel drive machinery, the QBE89G uses a quill type input shaft. Lightweight construction and user adaptability were key criteria during Quaife’s design of the QBE89G, the structure of the transmission is a lightweight alloy two-piece casing that reduces the unit’s overall weight to just 33 kilos. This format ideally suits the demands front engined, rear wheel drive cars running small capacity engines with a narrow power band. The innovative seven-speed layout fulfils market demands from specialist sportscar manufacturers and motorsport customers requiring an in-line sequential transmission with ultra close ratios. Called the QBE89G, the seven-speed unit debuted in prototype form at the Autosport show in 2012 and is now in full production, having passed its extensive bench and field testing programme. Quaife Engineering, the renowned automotive high performance transmission specialist, is delighted to announce the production launch of an in-line gearbox featuring seven forward gears – a first for the firm. QBE89G seven-speed sequential in-line gearbox now in production Hopefully Quaife will produce one for rear engine rear wheel drive Elise/Exige
