Just 50 ‘C16’ cars were manufactured for the UK-market, initially equipped with an uprated engine of 330bhp (from 300) mated to a 4-speed transmission. However, at the end of 1988, the uprated 5-Speed G50 gearbox was introduced, dramatically easing the peaks in power delivery by reducing the effects of ‘turbo-lag’. The factory SE also benefited from a dual-exit exhaust system, limited-slip differential, heated front seats and a sunroof.
Porsche made its first and most significant changes to the 930 for 1978 model year, enlarging the engine bore by 2 mm (0.08 in) to a total displacement of 3,299 cc (3.3 L; 201.3 cu in) and adding an air-to-air intercooler. The suspension benefitted from new anti-roll bars, firmer shocks and larger diameter rear torsion bars. While the increase in displacement increased power output and torque, it also increased the weight of the vehicle, which contributed to a substantial change in the handling and character of the car compared to the Earlier 3.0-Litre Models.
The 911 Turbo was put into production in 1975. While the original purpose of the 911 Turbo was to gain homologation for the 1976 racing season, it quickly became popular among car enthusiasts. Ernst Fuhrmann adapted the turbo-technology originally developed for the 917/30 CAN-AM car and applied it to the 3.0 litre flat-six used in the Carrera RS 3.0, thus creating what Porsche internally dubbed as the 930. Total power output from the engine was 260 bhp and 254 ft lbs of torque.
Only 50 units made. The 911 Turbo Limited Edition comes equipped with the 330 bhp power unit normally only available in the 911 Turbo with Sport Equipment. In addition, the fitment of a limited slip differential as standard ensures the the increased engine performance can be used to it’s fullest extent. This Limited Edition also adopts the rear wheel air intakes of the Sport Equipment version. Essentially an SE without a slantnose front.
Slantnosed and based on that of the 935 racecars, with pop-up headlamps. The front spoiler was made deeper in order to accommodate the extra oil cooler, while intakes in the rear wings fed air to the brakes. The larger turbocharger and four-outlet exhaust gave 30bhp of extra power. Porsche began their “special order program” offering a Flachbau option (Slantnose) for the 930 in very limited production. All of this at a cost of nearly 2 times the standard 930S.
Introducing this new top-of-the-range model, Porsche is once again placing a 911 Turbo Cabriolet right at the top of the family after a break of 14 years: From 1987 - 1989 the Porsche 930, as the first Turbo was code-named within the Company, set the first milestone in the history of these outstanding open-air sports cars. With cylinders still featuring two valves each at the time, the 3.3-litre power unit driving the first Turbo Cabriolet offered maximum output quite unique at the time of 300 bhp or 221 kW. Acceleration from 0 to 100 km/h was in 5.2 seconds and the car had a top speed of 260 km/h or 161 mph.
The Porsche factory had 93 Turbo chassis left. These were all transferred to Porsche Exclusiv and hand built as the very special 964 Turbo 3.6 S. They were offered with normal, or ‘Flachbau’ slant nose front ends. While the vast majority of Turbo S’ were fitted with the ‘Flachbau’ nose as a no-cost option, the Turbo S could also be had with the traditional 964 nose as well. In all, 76 Flatnose cars were made while 17 non-Flatnose (known as Package option) cars were made. These cars were also fitted with the X88 option, which increased power to 380 hp. 75 flatnose units were produced.
The top model in the Porsche Macan lineup is the Macan Turbo. It launched in 2016 as the most powerful vehicle in the competitive compact SUV segment and its 3.6 liter twin-turbo V6 engine is a real gem. Good for 395 bhp @ 6000 rpm and torque of 406 ft lbs @ 1350 rpm, it helps the Macan Turbo accelerate from 0 to 60 mph in just 4.50 seconds (with the Sport Chrono package fitted) on its way to a top speed of 165 mph.
19 non 'slant nose' or Package cars were made for the USA only. Very rare. The Porsche factory had 93 Turbo chassis left.

Engine based on modified 3.6 litre 964 unit. Speedline wheels with big red brake calipers. Lessons learned in the Carrera Cup series proved the reliability of the new 3.6-litre engine. An additional three millimetres on the bore and two millimetres on the stroke, resulted in an increase in capacity of 300 cc. Combined with the turbo optimised cylinders, pistons and crank train, and an increase in the compression ratio from 7.0 to 7.5:1, this helped to boost power to 360 bhp. Torque was increased significantly to 520 Nm at 4200 rpm, up from 450 Nm at 4500 rpm in the earlier car.
All Porsche 911s are turbocharged these days but the Turbo model is something special. It gets the twin-turbo 3.7-liter flat six with tons of power and a huge $33,000 savings over the Turbo S. Thanks to an output of 573 hp, marking an increase of 32 hp over the predecessor, the new 911 Turbo Cabriolet accelerates from 0 to 60 mph in 2.8 seconds (0.2 seconds faster than before). The Turbo Cabriolet basically handles like a coupe.
It would be a disservice to call this new Turbo a "lesser" car than the Turbo S, but it does have less in most departments. Less power at 573 HP. Less features compared to the jam-packed Turbo S. Most importantly, less money required to put one in your garage. This also is not to say that the new Turbo isn't anything short of a monster. It will still go 0 to 60 in 2.8 seconds, will corner like it was on rails with Porsche Torque Management (PTM) all-wheel-drive.
The 2022 Porsche 911 Turbo S Cabriolet is a formidable beast. The new Turbo S comes with an all-new, 3.8 liter boxer six with two variable turbine geometry (VTG) turbochargers. The power output is a staggering 640 hp and 590 lbs-ft of torque. In keeping with previous Turbo models, the engine powers all four wheels. A new 8 speed automatic transmission with a manual mode manages the power, and can power the car to 60 mph in a hair under a claimed 2.7 seconds.
