I just sold a good strong running 200tdi engine for $2500. The disco 200tdi engine has a different front timing cover water pump,intake and exhaust manifolds than the defender engine. That said, its super easy to obtain a 300 tdi exhaust manifold and turbo on ebay UK for less than $200 and once bolted to the disco 200 tdi engine has the same configuration as a 300 tdi engine and will easily bolt into a left hand drive 90 or 110. 200 and 300 tdi cylinder heads are also intechangable-in fact most replacement heads now supplied for 200's in the UK are 300 castings. Additionally since the blocks are nearly identical the rear clutch covers can be swapped between 200 Tdi and 300tdi engines so either engine can be used with an lt77 or an r 380.
