Seriously, I wouldn't bother. Land Rover re-engineered the whole thing (pretty much) rather then try and get even more out out of what is essentially an over-worked and worked-over 2.25 diesel. Be happy with it (they aren't that bad if you're nice to them with oil changes etc.) or get a better engine.
