Porsche 951:
The Porsche 944 Turbo was introduced in the U.S. in 1986 and was discontinued in 1989 (although reportedly there are a very few 1990-91 944 Turbos out there). To distinguish it from the normally aspirated 944, the Porsche 944 Turbo is also known as the 951, similar to how Porsche distinguishes different model years of the 911, such as 993 and 996. The factory specs for the 951 include a 217-bhp 2.5-liter four-cylinder engine with a KKK turbo pumping out 11 psi of boost.
