I have decided to replace the engine, resulting in a 1.6 diesel engine found; want to buy;
So, I have a few questions:

1 - What is the fuel consumption rate (per hundred kilometers).
2 - Water-cooled gasoline engine power of less is more?
3 - To replace the engine, there is no need to replace the transmission? (Transmission is fabric, 4 ribs)
4 - In general, what steps should be taken to replace the engine?
5 - 1.6 diesel engine spare parts are available?
Thank you;
