Have fitted a GM 6.5 litre diesel to one, it only produced 160 brake so supercharged it to produce more power, it ran on 44" tyres importes from America and was a real beast, an added bonus was it wasted all the Land Rovers on and off road.

Unless you have vast pots of money, or my infinate engineering capabilities, and the access to equipment needed to engineer a project of this type; forget it.

Read the posts in the site, they will give you much valuable and practical information about what works and what does not; it is based upon owners practical experiences.
