Can a mk1 uno turbo gearbox be changed for a mk2?

If you mean bottom to top change then yes, but you need the gear linkage and bigger clutch.

Thank you, I have a mk1 uno turbo and the gearbox has blown up, I was just seeing what options I had, as Mk1 gearboxes are rare as rocking horse . . . .

Have a look which gearbox your MK1 has.. if there is an under car gear linkage you have the older type known as the bottom shift, which requires a fair few parts to convert to MK2 (i've done the conversion but not driven yet)

If the selector mechanism travels through the car and through the bulkhead and enters the top of the box it's the topshift (oddly enough). If you have this type, then it's much easier to convert to MK2. the MK2 box usually uses hydraulic clutch but can be converted to cable if you swap the clutch arm over as the casting retains the cable bits.

I think it was e reg and before which have the older box, and I guess you have this box as they are prone to failure by all accounts.

The top shifted gear version used the so called TIPO gearbox.
No hydraulics on a European UNO I know of.
The old gearbox is known for not being a reliable gearbox.
Also a good reason to swap to the newer TIPO gearbox.

RHD Unos with the later C510 "Turbo" box also used on diesels did have hydraulic clutches. Like mine does.

I'd bet the hydraulic clutch on the MK2 would only be for Right hand drive... just like the 1.0 n 1.1ie Uno and Novo Panda .

Don’t buy a box off a Tippo. as it’s ratios are not right and has different drive shaft matings IIR.
