Hi everyone, I’ve got a disco 1 with a 200tdi in it but it’s full of rust. Have the opportunity to buy a discovery 2 with a V8 in it. I’m really wanting to utilise the Tdi but I’m not sure how big of a job it would be to fit the tdi into the disco 2. Has anyone done this conversion or familiar with it? Im aware the engine mounts will need to be moved but not much else. Can I drop the who engine and box into the disco 2 without too much effort? Thanks everyone for your input
