I have a NA 1.3 petrol engine and wanna load a turbo. I am looking at second hand parts at online stores and wondering if it is a problem to use a turbo from diesel engine.
Does this make any difference on using diesel turbo or petrol turbo?

A turbo whether petrol or diesel is basically an exhaust driven rotor which forces air into the engine. It won't be a problem to install a diesel turbo in a petrol engine. But there are problems!
First of all before you start to turbo a 1.3 engine keep these things in mind.
Ok now that's taken care of so here are the list of things you would need to plan for in case you anyways decide to do the build.
Not at all. The turbo doesn't know whether it's a diesel or petrol turbo.
Just bear in mind that if you want to put a turbo on your car without doing lots of other modifications to your engine, you can't use much more boost than about 0.6 bar (I think that's about 8-10psi, but I could be wrong). The power gains would be minimal and you'd still need to have the car's software updated. At minimum I would suggest using a thicker head gasket to decrease the compression ratio ever so slightly to help avoid detonation. Then there's the matter of boost pipes, exhausts and intercoolers. It gets very expensive very quickly.
In my opinion, it would be better to acquire a secondhand Mini Cooper S supercharger (the older models were supercharged, not turbocharged) and have that installed. The installation is simpler and cheaper and will probably suit the car batter too. Superchargers don't require modifications to the exhaust, can run without an intercooler in low-boost scenarios and require less custom manifold work.
