Its the same as the
200Di - except with the turbo left on.
Why remove the turbo?
It makes installing the engine in a Series Land Rover much easier. You don't need the full-width radiator with oil cooler and intercooler, you can use the standard Series radiator instead. You don't need a custom-made exhaust system, just a simple fabricated front pipe to bolt onto the Series centre and rear sections.
With the turbo removed, the engine will be very understressed. It is designed to cope with the high temperatures and pressures of a turbo installation, and even in turbo form these engines are good for 250k miles or more. In non-turbo form they should last just about forever.
Downrating the engine will also give the transmission an easier time. A Disco 200TDi knocks out 111 bhp and huge amounts of low end torque - far more than a Series gearbox and rear axle were designed to cope with.
You can't use the extra power in normal conditions anyway. The brakes, suspension and steering on a Series vehicle are just not up to high speed driving. If you want to be able to cruise at 80mph, a Series vehicle is not the right vehicle for the job. If you are towing heavy trailers up steep hills, then the turbo will definitely make a difference, but then you will spend a lot of time replacing transmissions, half-shafts and diffs.
