UK 5 speed gearbox - with STI RA gear ratios
For sale is a hybrid gearbox.
This gearbox will drop into any UK/EU 5 speed car, no need to change rear diff, hubs, shafts etc.
Front diff, case and gearset from a MY95 STI RA gearbox Code TY752VB3EA
Centre diff, transfer case and 1.1:1 dropgears from a MY95 UK gearbox.
It has a 3.9 front diff, gear ratios 3.454 2.333 1.750 1.354 0.972 viscous centre diff, 1.1:1 drop gears.
The STI RA box has done 80k miles, but 10k miles ago was rebuilt by David at API. Yesterday the STI RA box had its DCCD replaced by a UK centre diff at Zen Performance. The UK centre diff came from a broken UK box that had stripped 3rd gear - so Zen stripped / cleaned / rebuilt the centre diff before mating it with the STI RA gearset.
The box has a very slight crunch on occaision when downshifting from 4th to 3rd, I have been told the synchros do not like certain oils and Castrol Driveline should cure this (it was previously using a fully synthetic gear oil).
Offers by PM
Cheers

i have just stripped 3rd gear, i'm after another box and i have a uk spec 95, not knowing about my ratios I'm not sure the final drive is the same, what sort of speed is at 3000k, travel alot of miles and do definitely need a long final drive, plus what sort of price are you after, thanks

I have 2 uk boxes, one with 2nd gone and the other needing the synchros replaced. Could i take 5th gear out off one of my uk boxes and put it in this box you have for sale?

Yes, I believe you can as long as they're 752 boxes, I think you change over the 5th-reverse cluster.
I'll double check

Yep, 5th gears from any 752 gearbox are interchangeable.
