JB1 lsd

[twingofuncup]

I am building a racing twingo for circuit and would like to install LSD to a JB1 gearbox. Any Ideas where to get it?
we must run 1.2 l engine

any idea about pricing? do I need to ship gearbox or can we install it here

I have no idea pal. I've tagged the resident gearbox guru for you so sit tight until he arrives👍.

Well assuming the jb1 gearbox runs the same size diff as a jb3/jc5, you’ve got a few options. I can supply and fit a Quaife or a gripper. Unfortunately I don’t know if they share the same sized diff.

Whereabouts in the world are you mate?

fwir they are the same.

Nice one mate. 👍🏻👍🏻

What's the difference between those two? Sorry but lsd is new to me. 💔💔💔

So the Quaife is what’s known as a automatic torque biasing differential, so it sends drive to the wheel that’s spinning, but it never fully locks giving 100% drive. A gripper is a plate diff. This means the amount of lock up the diff gives can be setup according to the desired usage. However, the gripper will need servicing to maintain the preload.

The Quaife is fit and forget.

You can build both of them over in Slovenia, but you’ll need to get someone to fit the original crownwheel to both diffs.

thanks. can you check if I can really fit it into JB1 gearbox (diff diameter, ...)

how much is such lsd

 

[JamesBryan]

Quaife LSD is around £1000 and a Gripper is around £1300.

Yeah plus postage to Slovenia, which tbh, I’m not keen on doing. Best option is to deal direct with Quaife/gripper.
