Ok to clarify I have a defender, it's a 1990 hi cap with a 2.5 td in it. I find the engine completely gutless not to mention it breathes heavily and drinks a lot of oil. I do alot of heavy towing and carrying(in the back) on both short and long journeys.
Basically instead of throwing good money after bad with the current engine I'm pondering on the options of a transplant. Iff I'm going to do it I only want to do it once so i need to make sure I get it right.
