Generally if a battery works in a 1000cc Uno, it will work in the Turbo. There's no difference in the battery tray or clamp, but the Turbo does have more equipment mounted around the battery.
The best new battery you can buy for the Turbo is - in NZ - a DIN55 battery. On these the terminals are below the top surface of the battery, so there's no risk of shorting on the bonnet, and the base flange is a generous size so it clamps into the tray properly. With the terminals away from you, the positive is on the left and the negative on the right. Best place to buy such a battery is The Warehouse - believe it or not - Exide Premium sealed no-maintenance costs $149.99. Although it's about 50% more expensive, you'll find it lasts far longer than the universal types from SuperCheap that have the removable cell covers. 'Sealed' batteries are not just ordinary batteries sealed-up - they also have longer-life plates and alloys designed to reduce gassing-off and therefore the need to top-up.
