For those of you who are into keeping the classic RR alive, I have transplanted successfully a TD5 defender engine married to a 4.6HSE autobox into a 1990 Range rover. The fit is as near to perfect as one might expect the only serious alterations are to the engine mounts, and the electrics, the Aircon is a challenge but mamageable with some perseverance!
should anyone want further details am happy to provide!
