@Greg rrr has just posted about a company that provides stronger 3rd and 4th gears.
Not sure how they compare to Jubu but worth a look see?

Yeah these guys have been around a while claim to a have run 500hp through them. (no mention of torque, must be pretty high!)
Those are the SSC gears, MWR sell them over in the states so good to know you can get them in the UK, as far as I know they have the same rating as the JUBU gears - think JUBU are from Germany, SSC are from Australia.
Torque rating on them are at around 295ft/lbs but a lot run fine at 320ft/lbs - have heard some being run at 370 ft/lbs on track.
What are the prices like compared to Jubu?
Not that I'm going to get them haha.

Hanger 111 (lotus parts) sell them, £832 ex VAT so around a grand - coupled with the extra cost to fit them.

Surely the EB60 in the posts below is a cheaper option? I would have thought anything used in a 2.2 diesel turbo should be plenty strong enough? I'm sure Patrick Chambers has done an EB60 conversion for a ZZW30.

It would be close, but you'd have to fit an lsd to the EB/EA6x.
I'm on the fence for both options.
Also if you're planning to track the car consider some gearbox cooling because large and wider cogs will produce considerably more heat as a coefficient of increased friction.

Thats the EA box your thinking of.
Superstrong, but not suited for a sportscar, my Auris does 60mph on 2000rpm...
And over 60kg without LSD
