How come nobody offers a turbo kit for a 240D anymore?

[Uriah]

I seem to remember ads in Car & Driver, Road & Track, ect... back in the 70s and early 80s for a aftermarket turbo kit for the 240Ds. If ANY engine needs one, this would be it.

It don't look like the hardest thing to stick a turbo on, and I'd think there would be a market (however) small for one, worldwide.

I mean, seriously, Edelbrock makes aluminum heads for 351C/351M/400s which they made for 10 years tops (4 years for the 351C), they make stuff for AMCs, OLD Buick and Pontiac engines they havn't had forever, even old Cadiliacs (intakes).

You'd think somebody could make a turbo kit for a 240D and make a profit without it costing 10K, wouldn't you?
