Why the RS, GT2 and Cup are heavyweights

The sports models of the Porsche 993 represent the absolute high point of the last air-cooled generation. With the Carrera RS and the legendary GT2 Porsche created icons that today count among the most coveted collector's cars in the world.

These cars combine uncompromising lightweight construction with engineering straight from motorsport. Their small numbers and extreme performance make them rarities with enormous potential for growth in value. This buyer's guide sets out the differences, the technical subtleties and the risks of buying one of these heavyweights.

Focal points of the inspection: RS 3.8 M64/20 expertise, the rarity of the twin-turbo GT2, the Clubsport package analysis, the Cup history check.

The hierarchy of the sports models

From the naturally aspirated precision instrument to the twin-turbo monster

Carrera RS 3.8

1995-96 · 300 PS · 1,014 built

  • The concept: thoroughgoing lightweight construction (-100 kg)
  • A 3.8L naturally aspirated engine with VarioRam
  • A fixed rear wing, Speedline wheels
  • Variants: Basic or Clubsport (with a cage)
  • Pure driving dynamics

911 GT2

1995-98 · 430/450 PS · around 57 built

  • The concept: the most extreme road version
  • A 3.6L twin-turbo, but rear-wheel drive (no all-wheel drive)
  • Bolt-on wing extensions, a massive rear wing
  • Status: the Widowmaker
  • One of the most valuable Porsche models of all

Cup & GT2 Evo

Pure motorsport

  • Cup: a 3.8L naturally aspirated engine (around 310 PS) for the one-make series
  • Cup: not road-registered
  • GT2 Evo: the final stage, with as much as 600 PS, for GT1 racing
  • GT2 Evo: only around 11 built
Detailed analysis

Engineering, motorsport genes and weak points

Click the sections for the full assessment.

1. Engines: RS (naturally aspirated) vs GT2 (twin-turbo) +

RS engine (M64/20): 3.8 litres, VarioRam, larger inlet valves, forged pistons, lightened rocker arms. A single-mass flywheel for a sharp pick-up.

  • Risk: the valve guides wear at high revs. The oil pump is critical under track use

GT2 engine (M64/60): Based on the Turbo, but optimised: larger KKK K24 turbochargers, higher boost pressure (0.9 bar), strengthened internals. Enormous torque.

  • Servicing: extremely costly. The turbochargers are wear parts. The originality of the engine decides the value (matching numbers)
2. Suspension and brakes: motorsport engineering +

RS suspension: 30 mm lower, uniball joints instead of rubber (precise, but noisy), adjustable anti-roll bars.
GT2 suspension: A multi-link racing set-up, harder still.

Brake systems:

  • RS: 322 mm front, 299 mm rear. Racing ABS
  • GT2: Turbo brakes with additional cooling
  • Weak points: the uniball joints develop play. The aluminium callipers corrode. The special brake discs are expensive
3. Body and exterior: lightweight construction and aerodynamics +

RS: Thin glass, an aluminium front lid. Speedline wheels (three-piece).
GT2: Bolt-on wing extensions (fibreglass) and an enormous rear wing with ram-air scoops.

  • Risk: the lightweight parts are delicate. The GT2 extensions are prone to cracking. The spoiler is often damaged
  • Originality: Speedline wheels are extremely valuable (a set more than €10,000). Check for the "Speedline for Porsche" engraving
4. Transmission and drive: manual only +

Manual only. RS: G50/31 (short ratios). GT2: G50/30 (specific, rear-wheel drive).

  • Particularity: the GT2 has no all-wheel drive (weight saved for homologation). That is what makes it so vicious
  • Clutch: uprated, heavy. On the RS, the single-mass flywheel causes a rattle at idle (this is normal)

The strengths

  • The absolute high point of the last air-cooled generation
  • Uncompromising lightweight construction and engineering straight from motorsport
  • Small numbers: 1,014 RS, around 57 GT2, around 11 GT2 Evo
  • Enormous potential for growth in value, explosive development on the rarest cars
  • RS: the best compromise between usability and growth in value

The challenges

  • Extremely costly servicing, particularly on the GT2 (the turbochargers are wear parts)
  • Delicate lightweight parts, GT2 wing extensions prone to cracking
  • The uniball joints develop play, the aluminium callipers corrode
  • Originality decides the value: always check the matching numbers
  • RSR and RS replicas and badly modified cars are on the market

The 911Finder investment conclusion

The GT2 is the holy grail of the 993 range: prices beyond a million are a reality for the best cars. The RS offers the best compromise between usability and growth in value. A warning: Pay meticulous attention to originality (matching numbers, no irreversible modifications). A badly modified RS loses a great deal of value.
