sure you can take the engine out to 1293cc but you will need to take more out of the head or chose suitable pistons with a bigger dish than otherwise.

Is is in the engine the pistons and it runs and all ????

But what are you exactly looking for. For example the turbo head has bigger valves..

You can put a turbo on any engine, but the compression ratio and quality of the pistons will limit how much boost you can run.
Did you have it rebored yourself, do you know what pistons were used and about any other work done? What else do you know about the engine - engine number or model it was originally fitted to?
Fitting a turbo is more complicated than just bolting one on. If you're just looking for a bit more performance a modified cylinder head would be a better place to start.

I don't wish to discourage you, but fitting a turbo isn't as easy as I thought it would be.
Earlier this summer I agreed to help fit the turbo from an MG Metro, and by the end of a week I wished that I hadn't because of so many niggling things.
My sincere advice to you, if you are going to turbocharge your engine, is to take the car to an expert and to pay what ever it costs to have it done.

I gist want to know what it would take to change my car into a turbocharged car
OK. To do it properly:-................ You will need better tyres and brakes.
You will need the correct camshaft.
Because you are putting more charge into the cylinders, the compression needs to be lowered, either by having higher quality low compression pistons, by fitting a metal plate between the block and the head and/or removing metal from the combustion chamber.
Burning more charge in the same space puts more heat into the exhaust valve as the hot gas rushes out, so special valves and valve seats are needed.
The cooling system needs to be in tip-top condition to cope with the extra heat in the water.
As far as the actual turbo is concerned, if you aren't fitting a reconditioned turbo from a Mini/Metro, you have to make the inlet and exhaust manifolds, and the fuel system needs up grading.

If your compression ration is above 9:1 I'd be running low boost otherwise you'll run the risk off detonation and doing it all over again.

A 1275E is a South African model, which, unless it was imported into your country, suggests you're in SA (It doesn't say in your bio). If you are based in SA, and are looking for a recognised Mini engine builder, there are highly recommended folks in both Jo'burg and Cape Town who would be able to assist you with the job. They can take apart the engine to identify the cam, crank, rods, pistons and calculate the CR as advised by the experts in the comments above. They can then advise you on the costs to get the job done safely and correctly. Good luck, it sounds like a fun project :)
