There are lots of threads on here wth all the details you need do a search and I'm sure you'll turn something up. Try this link http://www.90county.co.uk/
 
Exhaust down pipe and routing of the intercooler pipes seem to be the most time consuming. Engine mounts from the turbo engine should bolt staight on to the disco engine.
My bother just converted his 85 110 2.5NA to a disco 200tdi and worked out fine, made his own downpipe.
There are lots of sites with step by step instructions/photos around but cant seem to remember the link adresses, someone will though.

It's a bit of a bitch compared to doing a nice Defender 200TDi to Defender 2.5TD but its still a pretty good conversion.
 
Somebody at work has done this. Didn't buy a modified downpipe, he used the old td manifold and turbo on the disco engine. He had to swap some studs for bolts but it was ok.
 
I swapped the 2.5 Petrol lump in my Ninety for a 200Tdi, much the same as Les Hensons' link [albeit my exhaust ain't so curvy :( ]

Also took a little longer, but I was doing much of the work single handed.

I found that the alternator & Starter connected straight onto the existing Petrol engine loom. The only major "additional" cost above the Disco engine & ancilliaries was a Kenlowe fan, and a new water temp gauge. The Disco temp sender was mismatched to the Ninety gauge which started reading "into the red" after 2 minutes ticking over :eek: ].

I tried a 200tdi spec gauge with the same result :( .
I then tried a Defender spec sender unit to tie in with the gauge - but the threads on the sender unit were different :scratchCh .

I then got a "universal" gauge which came with a handful of adaptors " To fit all makes of cars" - Well they don't 'kin fit on a 200Disco engine :depressed .

Eventually sorted it out by drilling and tapping a boss on the front face of the Thermostat housing and fitting the 1/8th NPTF sender in there :) .
