Yes,A turbo on a diesel is smallcompared to what is needed for a gas engine of the same size. For example most 4cyl Honda/Mitsubishi guys runturboes of the 5.9L cummins I6 on their 1.8-2.0L engines. Need to get some compressor maps and use a turbo calculator(found on multiple websites see sites below) to see what fits what you want to do. For example a stock engine daily drive needs a turbo completely different than a stroked alcohol pro import car. Usually replacement turbine housings are avail. to control when the boost starts to build.
Is it within the realm of possibility? Absolutely. Is it going to be in any way practical? Absolutely not.
No
No.
Only gas engines use blow off valves.
it depends on the size of the motor gas will burn hotter and faster then diesel could blow up

No
No. Do not put unleaded gas in a diesel tank.
Never put gas in a diesel car. And never put diesel in a gas car. An engine is built to handle one and not the other.
If a Holden Rodeo Turbo Diesel is using oil and new rings and a new turbo have been put in, it could be that the valves are leaking at the seals. Place a clean piece of cardboard under the vehicle overnight to see if it is leaking from the motor.
The 6.9 engine in the Ford trucks was an International/Navistar diesel, and was never built with a turbo. The 7.3 Was introduced with a turbo in the early 90's.
You should drain all the oil out and put the correct oil in.
