Last year my friend built a 1989 244GL into a turbo "sleeper". I don't have pictures but I have been for a ride in it- it's quick!
The mechanical donor car was a wrecked 91 940 Turbo. The complete 940 drivetrain was used, the complete B230FT, AW71 transmission, and engine computers from the 940. The engine and ECU wiring harness from the 940 was mated to the 240 chassis wiring harness- this was probably the most time consuming part. An intercooler from a 740T was used along with a new stock Nissens 240 radiator. The trans oil cooler and lines from the 940 were used and fit perfectly. The intercooler lines from the 940 were used. A small radiator overflow tank from a 740T was used. The 940 distributor was removed, a cam cap installed, and the 89 240 distributor used. Since both cars were LH 2.4 injection, there is no issue with matching up distributor hall sensors or relocating anything- the engine just uses the speed sensor in the stock location on the bell housign, and a stock set of 240 ignition cables works fine. There is a plug in the block that has to be removed to use the 240 distributor. The airbox required some fabrication but a stock box from a 240T would probably work here. Other than deciphering the functions of relays and such under the hood, the wiring was straightforward. The 940 alternator was kept in the stock location, top left side of the engine to make the wiring harness work. Obviously that's different from the way a 240 is wired, but it works well and everything fits fine. The engine did receive an electric fan, and clearance for that is tight at the waterpump pulley.
I would NOT recommend this unless you're quite familiar with these cars, or have a mechanic friend who is knowledgeable. Also, you would want to have a complete donor car side by side with the project car.
Outwardly the only clues are the 16" Hydra wheels, and the badge "240GL Intercooler". :)
