The Dornier 328 Jet comes to mind...but I'm sure someone else will provide more details.

DHC 5 Buffalo, a turbo prop
To NASA demonstrator, COANDA
The QSRA was a DHC-5 Buffalo, modified by Boeing by the installation of a new wing. QSRA was used for researching upper surface blowing, which allowed the aircraft to fly at very high lift coefficients.
and
The C-8A Buffalo Augmentor Wing Jet-STOL research aircraft is a modified version of a high-wing, high-tail, turboprop Buffalo military transport manufactured by DeHavilland, Ltd., of Canada, and designated NASA 716. It is used to study the design and operational characteristics of jet-STOL aircraft using split-flow turbofan engines to provide both propulsive and augmentor wing jet flows for increased powered-lift.

Quoting Aviopic (Reply 2):
I am not aware of any conversion the other way around but technically I don't see a problem.
If you mean converting turboprops to recips, Orenda used to offer a conversion to install large, liquid-cooled V-8s in King Airs.
If you mean converting turboprops to straight jets, Beechcraft tried such a thing. In 1980, they fitted JT15D turbofans to a King Air 200, but later decided to purchase Mitsubishi's design to use as their entry into the corporate jet market:

Quoting JetMech (Reply 8): Was the Turbo Commander the basis for the Jet Commander (IAI Westwind)?
Absolutely. It then became the Westwind II, then was bought by IAI and became the Astra, and is now owned by Gulfstream, and called the G150 after some significant mods...

G'day EssentialPowr . Does this mean that the Gulfstream G150 is in essence a heavily modified Turbo Commander?. It is very interesting to see how certain aircraft morph from previous designs! Is the G550 based on the G100 / G150?

No, as mentioned. The G100 I think is already out of production, replaced by the G150 which has a wider fuselage. The G200 is the former IAI Galaxy, which is shown in the bottom pic you provided. The current lineage of true Gulfstreams starts with the G350.

Quoting N231YE (Reply 19): Were those turbines intended for a R/C model airplane? They look very similar to R/C airplane turbines
They are in fact used on RC aircraft amongst other uses. Click the link in reply 15. It goes to the engine manufacturer's site. There's a whopping 35Kg of thrust between the two engines. Plenty for a 170Kg airplane though.
