I've got a 200Di fitted in my 2a. It feels like it put's out about the same power as my 2.25 petrol did but with more torque especially at low revs. Run it for over a year now and it's never missed a beat. On standard 4.7 diffs it feels a little under geared as it'll pull away in 2nd without trouble and the engine feels busy at higher speeds. Saying that it sat at around 70 with overdrive most of the way up the M74 yesterday with a load in the back only dropping a bit on the hills but still overtaking trucks with ease. Fuel ecomomy is much better, getting around 30 - 35mpg, which is about double what I got from the petrol. Going with a turbo but without intercooler is pretty common too as it cut's down on the plumbing making it a simpler install but you still get more power than a series transmission was designed for so you would need to drive with a degree of mechanical sympathy. There's plenty out there on the web about wrecked gearboxes in series motors after a few thousand miles behind a full fat 200Tdi. Others are happy with that install too. I guess some of it's down to how you drive it. It's a noisy beast though, probably louder without the turbo and vibrates a fair bit at tick over in a series motor although I kind of like the agricutural feel.
Give me a shout if you want any more info on how I did mine.
Danny.
