engine conversion

thinking of just rippin my 4.6 out and going for the 2.8 turbo shougun engine any one had one done or got any ideas on the wiring setup

Last friday I bought a 1982 Range Rover with the intention of replacing the worn out V8 with a 3.636 litre Isuzu diesel, I have a 1982 3.9l Isuzu diesel series 3 stage 1 Land Rover (factory option in Australia), I suspect we would have to replace the ignition switch with a diesel compatible one, for the glow plugs, but other than that, I think the rest of the electrics are fairly straight forward.
I am not familiar with the shougun 2.8 diesel, what were they in originally?
I have been thinking about putting a turbo on it, but maybe I should keep it simple.

kind regards...Ron
