Anyone know what turbo would fit on a Punto off a different car. For example Isuzu troopers use a form of IHI RHB52. Would this work?

A Diesel turbo on a Petrol engine may need the be stripped apart and rebuilt to cope with the higher temperatures. Even then you'd struggle to make the 1.2 to 1.5 bar of boost the Punto should be making.
Depending on what you're trying to achieve and what you have done to the engine so far you can get results from better intercooling, mapping and variable boost controlling before you mess around with bigger turbos.
Make sure you have an engine that can handle the extra boost before you get a bigger turbo. Make sure you can balance the air fuel ratio throughout so you don't detonate the pistons (the way I did putting a Volvo turbo on my Renault 5 GT).
Whatever you do make sure the engine is set up properly on a rolling road by someone who knows what they are doing. D.I.Y driveway stuff is all well and good but never be afraid to ask for advice.

Problem is I have two unfixable standard turbos. Not really after more power just something easier to get my hands on
If you buy anything but a Garrett you're likely to end up with another unfixable one.
Garrett do a sort of choose turbo by horsepower chart, so, a good start would be to find one that matches the bhp you want, then (several of the tubo sales companies do listings of what turbo was used for what car) see if you can find anything to suit.
Stay away from turbos without a wastegate (variable vane. etc.) and note that your ECU isn't exactly easy to tweak (which may have been part of the previous ones demise).

Unfixable?
Some companies offer turbos on an exchange basis. I used to talk to Keith at "Power Engineering" but that was ages ago. My neighbor used Ivor Searle Engineering last year when the turbo went on his VW Bora.
