Gaston Andrey Motorsports has extensive list of Porsche 911 Turbo's , ranging from 930, 964 & 993

For the 1975 model year, Porsche introduced the first production turbocharged 911’s. Only 284 examples built for the inaugural year in 1975 Although called the 930 Turbo (930 being its internal type number) in Europe, it was marketed as the 930 Turbo Carrera in North America. 1976 Turbo Carrera, Porsche only produced 530 U.S.-spec Type 930s built for that model year.  The body shape incorporated exaggerated fender flares and a large rear deck spoiler announced that the Turbo Carrera was no ordinary 911. The Turbo’s performance matched its looks; the turbocharged three-liter air-cooled engine delivered its power through a strengthened four-speed manual gearbox, and many were equipped with an optional limited-slip differential. 

 

 

Porsche 911 Turbo was revised in 1977 when the German manufacturer unveiled an upgraded version of the car. The new car had adjusted suspensions and new air deflectors installed in front of the rear wheels as well as a couple of new elements meant to improve the aerodynamics. The engine was upgraded too, the 3.3-liter being now able to produce a maximum power of 300 hp with a 0 to 100 km/h acceleration in 5.3 seconds. There would be only 727 North American-specification Turbos built and sold for model year 1977.

In 1978 Porsche revised the 930 with a 3.3-litre turbocharged engine with intercooler that produced 300 PS (220 kW; 300 hp). The increased engine size reduced the turbo lag. The intercooler required a "tea-tray" tail design for the whale tail. Porsche branded the car as the Porsche Turbo 

 

In 1980 Changing emissions regulations in Japan and the U.S. forced Porsche to withdraw the 930 from those markets.

  

In 1981, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end. Each Flachbau unit was handcrafted by remodeling the front fenders (option code 505). 948 units were built.

In 1986 the 930 Porsche was re-introduced to the U.S. market in with an emission-controlled engine. Porsche introduced targa and cabriolet variants, both of which proved popular.

 

In 1989, its last year of production, was the 930 equipped with a five-speed gearbox

Porsche produced the 964 Turbo from 90 to 94. The series 90- 92 used the 930's proven 3.3 L engine, improved to produce 320 PS (235 kW). Porsche produced 3,660 3.3 Liter Turbo’s from 90 to 92.In 93 Porsche increased the engine to a 3.6 Liter with 380 hp. The brakes were improved and a lower suspension with 18 inche wheels completed the product changes. Porsche produced 1,437 3.6 liter Turbo’s.

Porsche launched the new 993 Turbo 1995 . The 993 Turbo production was from 95 -97.  This was the first standard production Porsche with twin turbochargers and the first 911 Turbo to be equipped with permanent all-wheel-drive. The 3.6 L twin turbo M64/60 engine produced 408 PS (300 kW / 402 BHP). The performance was outstanding. The 993 was the last air-cooled 911 engine. The 993 was the first generation of 911 to have a standard six-speed. Other improvements include a new dual-flow exhaust, larger brakes with drilled discs, and revised power steering.
