no longer available from what I can gather!
Well thanks for that info.was just starting a search for a Celica box with the intention of building a spare box with Jubu gears for when the inevitable happens.
I believe they will be back in production soon …maybe a month or so …
From Hangar 111…
Mine is now back on the road with a full Kaaz set and a 3.9 final which is working well for me.
First is now a worthwhile gear (I felt previously it was just too short to be useful), now running to just over 50mph at the limiter with nice even gaps all the way through to 5th which runs to just under 130mph, with sixth a slightly bigger step into a good motorway cruising gear, which sees 3800revs at 80mph. I also took the opportunity to drop a quaife LSD in there while it was open, which makes the car more entertaining in the recent wet.
A new oil cooler appears to be keeping it all at a better temperature, hoping it’ll hang together for a while now!
That sounds good. What were the costs for that?
Are all the gears helical (is it quiet)
What are the thoughts on strength of the Kaaz kit to the Jubu kit??

I looked at the Kaaz gearset when I broke my gearbox, with quite a lot of investigation I found at the time they were sadly made with similar cheese to the standard gears, this might now have changed. There were not at the time made for high power just better ratios
They are still helical cut, but straighter than standard, so it is noisier than previously, but not intrusively. It’s tough to know for sure whether that’s due to the cut of the gear set, or the new slippy diff - either way I quite like the whine.
For comparison, there are some good photos of standard vs Jubu vs Kaaz here linky
From what I read as I rushed into getting it sorted, the ratios of the Jubu gears pushed a bigger gap between 2nd and 3rd, which I felt was already slightly uncomfortably wide.
The cost was a smidge over 4500, including having the diff and oil cooler installed.
In hindsight, I might have looked closer at going for an E153, especially as I’m looking to get some more power sorted before too long, I’ll be kicking myself if this set goes and I’m left looking at another replacement.
Did you read my post earlier post? Anyway I think you said your car was 240 so maybe upping to 260 is not that much of a risk is it? Fact is going any further will be but surly having the closer ratios will compensate? I wouldn’t of thought there’s that much difference on the straight between a 260 Kaaz set up and a car pushing 300. The reason why I say is if I ever starting wearing skirts and calling myself Tina a 260 set up like yours seems just about perfect, for track days.
Doesn’t 5th really whine lol?
I did read your earlier post - not sure which part of it you mean?
My car is currently a 240 but it replaces a 996 Turbo, so there are times I miss the power.
Right now I don’t believe the car is any faster accelerating, as the ratios aren’t any shorter, but taller and closer, which in practice means it’s more likely to have the right ratio available to fumble for.
On failures, it’s not clear to me what the facts are. There is most certainly a heat component, so I’m hopeful that the cooler will stabilise things significantly.
My logic, however contrived or over-optimistic, goes along the lines of
a. the 260 cars have a standard box, and they’re not disintegrating all over the show.
b.the Kaaz gearset being able to handle (some) more power than standard, and
c. the oil cooler keeping it in check,
so a reasonable dose of extra power shouldn’t be too unsafe, I’d like to go well beyond 260.
Only time will tell.
I don’t see how you can compare a 996 Turbo with and an Exige… Adding more power going well beyond 260 will kill an OEM gearbox and maybe that little bit further a Kaaz gearbox. The cooling seems bang on it would seem but all you are doing is playing Russian Roulette like everybody else. And like everyone else in pursuit of more power knowing there is a weakness just seems crazy bare in mind what you are driving and what the car is capable of but even then it’s only capable to a point. So while you have a Kaaz box enjoy it and change something else to make it quicker…I assume it’s a track car btw? I defiantly be buying another box with Jubu gears as a spare just in case the worst should happen or if not selling on for good money when time to sell.
It’s just the same old story that’s all… Anyway I genuinely hope it works out.
Have you been on the vino Jonny ??
Ha ha yea I’ll never understand you guys… I’ll mind my own NA business
NA boxes break also you just have to drive them like a man… :whistle:

We’re running Kaaz now in all of the race 2-elevens - granted the decision was a forced one due to lack of Juba but we wont be going back. Very straightforward to fit, similar cost (�2k) but you get a full gear set and you don’t have to press on \ off any bits from old stuff.
The gearing is pretty good (you have circa 600-800 rpm left at the bottom of Hangar Straight (2-Eleven with 270 kit), it’s quiet and the quality is very good and the quality of gear change is transformed but I’ll reserve judgement on how long they last for a a few more races yet. So far we’ve done one race weekend and 8 track days.
Stephen ,just curious but how long are you seeing standard boxes last for on the 270 cars?
NA boxes break also you just have to drive them like a man… :whistle:
Lol is that like using a gear other than third . Out of interest what power were you running when you bust your Kaaz gears Frank?
I skipped doing R$D for Kaaz gears after hearing about their failures and went right to the E153…
Remember my third gear pulls from 5-130mph…
Watching this topic with interest - caurrently @ ~290bbhp so waiting for the gearbox to fall apart…

Get a cooler on it if you use it on track it will probably help its longevity, speak to JSR or EA depending on which end of the country you live in
went to Komo-tec yesterday
asked him about the Jubu gearset
he told me he’s waiting for more than a year now from Jubu to supply some sets
so he puts OEM parts on a failed gearbox
