Client vision

Our client approached us with a deep appreciation for the raw character of the classic 930 Turbo — one of the most charismatic and visceral 911-era cars ever built. The goal was to preserve the iconic silhouette and engaging driving feel, while enhancing performance, reliability, and everyday usability without diluting the original character.

Challenges & Considerations

  • Balancing authenticity and performance: Maintaining the original Turbo DNA while introducing modern functionality and drivability.
  • Engineering for longevity: Enhancing engine, cooling, and drivetrain components to handle increased power and real-world usage.
  • Detail-oriented build: OEM-level finish quality, subtle integration of upgrades, and bespoke tailoring to owner specifications.

Project Scope & Services

Restoration & OEM-Plus Upgrades

  • Chassis & body: Restoration of structural items and corrosion protection; alignment of panel fitment to OEM standards.
  • Engine & turbo system: Tailored engine and boost concept tuned for both mid-range response and high-end power delivery, with a focus on reliability and durability.  
  • Forced induction: Modern charge-air management and optimized intercooling to reduce turbo lag and improve thermal stability.  
  • Exhaust & sound: Custom exhaust engineered for authentic character and usable sound without unnecessary volume peaks.  
  • Transmission & drivability: Strengthened gearbox path suited to increased torque; tailored gearing and clutch choice based on use case.  
  • Suspension & brakes: Modern suspension geometry with adjustable coilovers (e.g., KW Clubsport or equivalent) for improved handling and road compliance; braking upgrades for confidence.  
  • Comfort & features: Discreet integration of air conditioning, refined electrical systems, and bespoke interior materials to elevate day-to-day enjoyment.

Why this 911 Turbo matters

The Porsche 930 Turbo 3.3 is more than a classic 911 — it defined turbocharged performance for an era. Its combination of air-cooled character, iconic wide-body stance, and iconic “whaletail” spoiler cemented its place in automotive history.  

While raw and demanding in stock form, a thoughtful OEM-Plus restoration brings out the best of the platform: rapid acceleration, engaging dynamics, and a visceral sensory experience that connects driver and machine.
