The Porsche 911 Turbo has been in continuous production since 1975, making it the longest-running Turbo line in the modern sports car canon. From the original 930 Turbo with its single turbo, rear-wheel drive, and notorious 'widow maker' reputation, to the current 992 Turbo S with permanent four-wheel drive, twin-turbo, and more than 650 hp: each generation has redefined the Turbo without losing its wide rear haunches and visual identity. For collectors the Turbo line represents its own market class within the 911 culture. A 911 Turbo is not sold to just any buyer; it is passed on to someone who knows the 930 tradition and values the difference between a 993 Turbo and a 996 Turbo S.
The Porsche 930 Turbo was unveiled in 1975 as the road-legal version of the racing Turbo developed by Porsche under IMSA and FIA regulations. The 3.0-litre single turbo initially produced 256 hp and was replaced in 1978 by the 3.3-litre with 300 hp, later raised to 330 hp in the closing years. The 930 was notorious for its turbo lag: at lower revs the engine responded little to throttle, but at higher revs the turbo would suddenly spool, causing unexpected reactions from the car. For inexperienced drivers this was a dangerous combination, earning the 930 its 'widow maker' reputation. For collectors an original 930 in factory specification and original colour (particularly Slate Grey, Mexico Blue, or Speed Yellow) is among the most highly regarded classic 911 specifications.
The 964 Turbo (1990-1994) initially used the 3.3-litre engine from the 930, uprated to 320 hp and paired with the modern 964 chassis. From 1993 the 3.6-litre Turbo arrived with 360 hp. The 964 Turbo S (1992-1993, around 86 built) and Turbo S Leichtbau (around 80 built) are rare specifications that sit above the regular Turbo for collectors. The 993 Turbo (1995-1998) introduced twin-turbo chargers and permanent four-wheel drive for the first time in a 911 Turbo. With 408 hp and steadily reacting turbos, the 993 broke with the turbo-lag tradition. The 993 Turbo S (~345 built, 450 hp) is one of the rarest 993s and ranks among the most valuable regular 911 Turbos.
The 996 Turbo (2000-2005) and 997 Turbo (2006-2012) used the twin-turbo Mezger engine, technically related to the racing 911 engines designed by Hans Mezger. The 996 Turbo produced 420 hp from 3.6 litres, with the optional X50 package for 450 hp. The 997 Turbo (2006-2009) brought 480 hp and introduced variable geometry turbos (VTG) on a petrol engine for the first time. The 997 Turbo S (2010-2012) produced 530 hp and received PDK as standard. For modern 911 Turbo collectors the Mezger specifications (particularly the 997.2 Turbo S in manual) are among the most sought-after regular modern 911s. Their valuation curve has risen consistently since 2018.
With the 991 Turbo (2014-2019) Porsche left the Mezger engine in the Turbo line. The new MA1.75 twin-turbo engine produced 520 hp in the Turbo and 580 hp in the Turbo S, with PDK as standard. The 991.2 Turbo (from 2017) brought 540 hp and the Turbo S 580 hp. The current 992 Turbo (2020-present) produces 580 hp and the 992 Turbo S 650 hp; both with integrated electric assistance and advanced aerodynamics. For modern 911 Turbo buyers, factory PTS colours, factory aerokit, and Lightweight Package options are important differentiating characteristics. For sellers in the 991/992 class, full Porsche service history and original specification are crucial.
The 911 Turbo line represents one of the most differentiated segments in the Porsche market. Classic Turbos (930, 964) have appreciated for years, with the rare specifications (Turbo S Leichtbau, 1980s 3.0 Turbo Carrera) in their own high tier. Mezger Turbos (996, 997) are the most sought-after specifications for modern collectors. Modern 991 and 992 Turbos are the most practical 911 Turbos for driving-oriented buyers. For sellers this means a well-documented 911 Turbo with proven service history and original specification attracts strong international interest. The buyer you want is an enthusiast who recognises the difference between single turbo and twin-turbo and who values the Mezger culture.
930 (1975-1989, single turbo RWD), 964 Turbo (1990-1994, single turbo RWD), 993 Turbo (1995-1998, twin-turbo AWD), 996 Turbo (2000-2005, twin-turbo Mezger AWD), 997 Turbo (2006-2012, Mezger AWD), 991 Turbo (2014-2019, water-cooled AWD), or 992 Turbo (2020-present). Each generation has its own collector class.
The 996 and 997 Turbo use the twin-turbo Mezger engine, technically unrelated to the M96/M97. The Mezger has dry-sump lubrication and no IMS bearing. For collectors a Mezger Turbo (particularly the 997.2 Turbo S) is among the most sought-after modern 911 Turbo specifications.
For 930: original colours such as Mexico Blue, Speed Yellow, Grand Prix White, Guards Red. For modern Turbos: factory PTS (Paint to Sample), factory aerokit, carbon packs, Centre Lock wheels. Original order configuration or factory build sheet strongly drives price.
For air-cooled Turbos (930, 964): valve clearance, timing chains, turbo condition, and oil cooling. For water-cooled Turbos (993, 996, 997, 991, 992): turbo status, cooling system, head gaskets, whether Mezger or MA1.75. Service at Porsche or a recognised specialist is essential.
The Turbo's wider rear spoiler and rear haunches are structurally part of the body, not aftermarket. For the 930 and 964: rust investigation on floor pans, sills, fender seams, and frame. For modern Turbos: panel condition, carbon panel state, and any damage history.
Photos of the VIN plate and engine block number side by side. For the 930 Turbo and 964 Turbo, matching numbers are decisive for collector valuation. For modern Turbos, particularly Turbo S and Sport Classic specifications, a Porsche Classic Certificate of Authenticity confirms factory specification.
Note: These factors may influence buyer interest. Value depends on many factors.
Model year, generation (930, 964, 993, 996, 997, 991, 992), specification (Turbo, Turbo S, Turbo S Leichtbau, Turbo S Exclusive), engine code (air-cooled, Mezger, MA1.75, or 992 architecture), gearbox. Precise identification is essential for the right buyer pool.
Available via Porsche Classic in Stuttgart based on the VIN. For the 930, 964 Turbo S, 993 Turbo S, 996/997 Turbo S, and rare factory specifications this document is decisive for collectors.
For air-cooled Turbos: valve clearance, timing chains, turbo condition, oil cooling. For Mezger Turbos: timing chains, head gaskets, cooling system. For modern Turbos: turbo condition and factory software updates. Service at Porsche or a recognised specialist is essential.
For the 930 and 964: photos of floor pans, sills, fender seams, frame, and the wide-body rear haunches. For modern Turbos: panel condition, carbon panel state, factory aerokit confirmation if applicable. Original paint (no respraying) strongly drives price.
Photos of the VIN plate and engine block number side by side. For the 930 Turbo, 964 Turbo S, 993 Turbo S, and modern Turbo S specifications, matching numbers and/or a Porsche Classic confirmation are essentially mandatory for top valuation.
Paint colour with factory code, Paint-to-Sample confirmation if applicable, factory carbon packs, Centre Lock wheels, factory aerokit, sports seats, leather specification. Original order configuration or factory build sheet reinforces value.
Many Turbos have received aftermarket exhausts, different wheels, or engine tuning. For collectors factory specification is highly valued. Document all modifications; keep original parts for possible refitting.
