Is it an advantage?
What are the differences?

Hello,
Turbos for diesel and petrol cars have different flow characteristics and different demands. Each turbocharger is characterized according to pressure ratio, flow properties etc. there are lots of types, for various applications.
Diesel turbos have their work bands in the lower engine speed regions, where diesel gives most of their powers. They rely on the exhaust design which is totally different with diesels and petrols. Diesel have a very restictive exhaust to maintain low-RPM torque and diesel turbos above 3000-3500 RPM are bypassed by the wastegate. In contradiction, single-turbo petrol engines are starting to 'work' above 2000-2500 RPM, and have their peak at 6000-7000 RPM. They don't have such a massive wastegate valves, for they are working on higher RPMs.
So, unfortunately, the answer is no. There are no advantages.
Regards

The short answer is yes - but it depends. A turbocharger simply is a compressor driven by the expanding hot exhaust gases. However, turbos are sized for different applications. You wouldn't use a turbo from an over-the-road Caterpillar Diesel and bolt it onto a 2 liter 4-cylinder engine and expect good results.
Engine designers specify turbochargers based primarily on total airflow through the engine, which is a function of engine displacement and rpm range. Next, exhaust temperatures and pressures are taken into consideration, then finally the level of boost for the intake side is considered. If anything, I would expect a turbocharger from a Diesel application might be a bit more rugged than one from a comparably-sized gasoline engine. But in general, you need to know a lot more specific information in order to achieve a good match of turbo to engine.

If you mean, can a turbo diesel motor REPLACE a petrol motor... Yes... VW fanatics do it all the time... but only on cars designed for them... (like you can put a turbo diesel into a VW rabbit pickup that once had a petrol motor).

A turbo is a turbo is a turbo. The real question is why do you want to use it. Are you able to fabricate the adapter plate you will need to use it? Might actually be cheaper in the long run to just go buy the turbo unit for your vehicle.

probably not
