Yes it does, you just need to swap the clutch operating arm from your old PG1 to the new one

£50 for a torsen one, didn't realise they were so cheap these days! Mine has been sitting in my garage for 8 months as a back up in case my current gearbox has issues.

Could you not remove the Diff from the Lotus one pictured above and fit it to your current box? - I'd be tempted to do that and at the same time fit steel cage bearings and replace the seals... If the price was right?

I'm aware of a few diffs for the ZS, Quaife, Torsen and Gripper? Not sure if there are any others?

From what I've read Gripper are the best, followed by Quaife then Torsen? How does a Torsen compare to a Quaife? Apart from cost!

I could go that route, but that would be a specialist job because I'm not confident enough with gearbox internals. I did message a fella known as "Rally Matt" on XPF who built/builds the PG1 boxes with the Quaife diffs and steel caged bearings. I think people have had some problems getting hold of him, but I messaged him anyway. I think he is based somewhere near Silverstone?

What's the cost of installing diff and steel bearings into a box, anyone got a rough idea? There's two places local to me that do gearbox rebuilds, although one of them gets terrible reviews!

No Idea on costs I'm afraid!

As for Matt, used to know him quite well back in the day (back when he was a Rally driver for MG and Leda supplied him suspension!) IIRC he is based within silverstone itself, I would assume he has changed his phone number since the last time I spoke to him, but I still have his mobile number from 10 years ago... lol

As for quality of his work, I can't say I've heard of anything bad about him... I think he did some work on a few Diesels on here at some point and IIRC they were happy. Plus he's always given me sound advice on the phone :)

with carbon plate diffs being only small extra cost over a brand new quaife, you wonder why anyone bothers with helical diffs.

So am I right in saying a complete 620ti box will bolt straight to a kv6 and have the same ratios?

If so, fitting an lsd to the 180 is going to be easier than fitting the one to the diesel!

Cutting a long story short, I have found someone who is willing to part with a PG1 gearbox fitted with steel caged bearings and the Quaife differential.......

How much are they after?
