There is a better option. The Rover is powered by a Rover v8, I know big surprise there. The big deal is that so was 3/4 of anything and everything British a few years back. You can get a TVR or Jag engine with at least 100 extra ponies and it probably won't even blow up. Sure it will cost a few extra pennies, but you would need an engine rebuild every other day if you ran NOS in a stock Disco mill.
Or if you have ots of extra cash try a Mercedes Benz 5.5 liter supercharged V8, or a Porcshe engine, either one would work.
