i bet most of you are sick of engine conversion advice. please bear with me as i'm new to landrovers and love them already apart from being overtaken by lorries and milkfloats. i have a 110 2.5 n/a, i've been offered a well mantained 300tdi disco lump with auto gearbox. what are my options hear, will the two go together in the defender with a bit of chopping and glueing or do i need to get a r380 if the auto box won't work, what mods would couple the gearbox to the engine and make it work OR should i forget the whole 300 idea and get a 200tdi and put onto my existing gearbox? the chap's holding the engine till tomorrow, so if there is anyone still awake please run me through the best options so i can enjoy my landy even more.
