After nearly three years of suffering a tortuous linkage, slow changes, oil seepage, and a crunchy reverse I've decided to upgrade the gearbox in my 6a when the engine comes out for a rebuild this spring.
RX8 boxes seem to be en vogue at the moment although I can't find a project thread from anyone who's mated one to an Essex (but Corky's Cologne thread has provided inspiration).
After a bit of research I've decided to take the plunge and hope to keep up a project thread, which is more likely to be a plea for help and advice rather than anything instructional! Here's a breakdown of where I'm at and what's known:The gearbox:
I've purchased a 5 speed box complete with slave and stick. The ratios seem better suited, although I then phoned p9cyoplates who think the 5 speed is weaker and may struggle with my ~200 bhp Essex Adaptor plate:
Purchased from p9cyoplates.co.uk. Master cylinder:
I'll have a braided hose made up and will try to use the existing master cylinder Clutch:
standard (uprated) Essex itemProp:
custom made utilising the RX8 yokeGearbox mount:
Will need to sit slightly further back from existing mount. Custom bracket using existing bolt holesSpigot bearing:
not sure about this. I think it needs one from a type 9? p9cyoplates no longer include a spigot extender as part of their Essex kit and seem to think if the input shaft isn't long enough to fully home in the bearing just leave it out. Surely not?! it must be known if the input shaft is long enough.Reverse switch:
Straightforward replacement of existing switchSpeedometer:
not sure which way to go here. GPS or prop sensor?Gearstick position:
If the RX8 box is the same length as the type 9 where will the stick emerge and how best to cover the existing hole in the interior fairing? I doubt a massive gaiter will do.
Have I missed anything out?
