Auid 2.0L I-5 Turbodiesel
 

Will the Audi 2.0L I-5 Turbodiesel bolt up to the 5 speed from a diesel 200 series? And will it mount in the engine bay of the same car? Thanks

The back of the motor is the same and will bolt right up but the engine mounting locations, oil pan profile, hose connections, cooling fan arrangement, etc may all present challenges. Should not be difficult by and large to work through those, but....

The 2.4L 6-cylinder bolts right in, runs smoother, makes more power, and is easier to get parts for. :)

What would be your reason for wanting to put the five in instead?

Interesting aside: for a few short years, from 1979 to 1981, Volvo in fact did produce and sell a small number of 200 series Diesels that were equipped from the factory with what they called the "D20" engine, which was the Volvo name for, that's right, the 2.0L Audi diesel inline five. Supposedly the cars were only sold in a few Nordic markets and were intended for urban taxi duty. There were evidently so few of them produced that my official Volvo parts catalog does not even include correct diagrams for the D20 engine -- all the D20 diagrams are just pictures of D24 parts, with the labels and part numbers and quantities altered as necessary. Many of the parts are shared of course, as far as consumables, moving parts, etc, but if you search a part number for a part that IS specific to the D20 engine (for instance P/N 1257644, the D20 oil pan), you'll find that the modern parts systems don't even lead to a reference for that part. Not "discontinued" -- just nothing there, no part found. Seems Volvo has forgotten these cars were ever produced! And maybe not on accident..... they must have been truly painful to drive.... :D

I wonder if there is a single one of them left intact anywhere in the world.

There is a turbo diesel audi for sale for fairly cheap. I have been looking for a diesel volvo for a awhile and they all seem to either be $700-$100 and need a LOT of work or $3000+ and still need work. I just thought about buying a good looking wagon that needs engine work and the Audi and combining the 2. Wouldn't the addition of the turbo on the 5 cyl have more power than the 6 cyl N/A in the 240's?

Is the Audi in perfect condition? If it's selling for 700 bucks it probably needs work too... I don't know how the turbo 5 would compare to the naturally-aspirated six in terms of power and driveability, but, certainly both would have less power than the six with the turbo, and the D24T turbo six should be easier to put into a 240 than the turbo five anyway.

Not trying to discourage the idea of the project, but the Audi engine is architecturally identical to the Volvo motor except for the difference in the number of cylinders so just keep in mind that if all the Volvos you are finding need help, the Audi will probably not be any better! And if you decide you're going to invest some work and money into something, my guess is that you'd get better results for your dollar by starting with the larger-displacement six...
