I'm guessing that something happened whit the LSD.
When I have the wheels up and turn the wheel and no gear its occasionally hit something and the other wheel turns at the opposite direction for a while and when I passed the spot it turns normal again🤔

Maybe your engine mods were just a step to far for the standard box?

Touch wood, I've not had a k20 gearbox failure though I've driven two atoms hard on track over 15 years, and given weight of the car, I suspect it just a bad box.

Worth checking the box on why it failed. You can go for straight cut etc for strength but I doubt it failed due to the box having too much power/torque.

If you've got to have the gearbox changed, why not go for paddle shift gearbox?

You will be best advised by calling the Ariel factory. Hope it works out.

My 3.5R whit K24Z7 engine just broked down, there was a bang on second or third gear out of a roundabout and there's something lose/broken in the gearbox.
It only have 6000km so it was a big and unexpected surprise...
Is it common whit gearbox failures?
Next problem is that the engine and il guess also the gearbox are US only civic Si 2012, so no spares in EU.
Are this gearbox identical to an EU civic K20?
Anything I can do to increase the strength in the box when I'm in it?
