Project Vehicle Porsche 911 RSC

Base vehicle - Facts & starting point

• Model: Porsche 911 Carrera 3,2l (G-Model)
• Year of manufacture / first registration: 1987
• Engine: 3.2 l six-cylinder boxer engine
• Performance: 170 kW / 231 hp
• Gear mechanism: 5-speed G50 manual
• Colour: Grand Prix White (Uni)

All components were either replaced with new original Porsche parts or extensively refurbished and restored to mint condition.
At the time of reconstruction, the bodywork was technically and visually equivalent to new.

The Porsche 911 RSC's original 3.2 l six-cylinder boxer engine was thoroughly redeveloped during a complete engine overhaul and expanded to a displacement of 3.4 l.
On this basis, the engine was fitted with the CARGRAPHIC Performance Kit 7, which was developed in collaboration with RS-Tuning Schmirler and precisely tuned on the performance test bench – with the clear aim of harmonising maximum performance, torque and drivability

Components of the Performance Kit 7

The Performance Kit 7 consists of a precisely coordinated package of high-quality components for increasing power and torque, including:

• Second-generation BOSCH air mass sensor with digital measurement technology
• Cup sports air filter including adapted wiring harness
• Optimised engine control unit (DME/CHIP)
• Complete exhaust system based on GT manifold
• RSC set consisting of 3.4 l displacement pistons and cylinders with 10.8:1 compression ratio
• RSC camshafts including valve springs and valve spring retainers
• RSC throttle valve with AT adapter
• Modified spark plugs and injectors

Driving experience & character

The result is an engine that is significantly superior to the standard 3.2 l engine in all areas. The increased displacement, noticeably higher torque and pronounced revving ensure direct, powerful response across the entire rev range – combined with an authentic, classic mechanical boxer character that can only be found in air-cooled 911s of this generation.

To the performance kit...

In combination with CARGRAPHIC Sport HJS / Emitec trimetallic catalytic converters, an optimum balance between exhaust gas purification, performance and sound is achieved. The catalytic converters used feature a high-performance trimetal coating and ensure low exhaust back pressure while providing reliable exhaust aftertreatment.

The exhaust system ensures direct throttle response, supports the engine's power delivery across the entire rev range and produces a distinctive, motorsport-inspired sound – present under load, controlled in the partial load range and suitable for long distances in everyday use. The sound remains authentic at all times and underlines the classic character of the air-cooled six-cylinder boxer engine.

Exhaust components in detail

• CARGRAPHIC ID42 GT exhaust manifold with 42 mm primary pipe inner diameter and enlarged collector boxes with 2.5" / 63.50 mm cone connection
• CARGRAPHIC high-performance catalytic converter set with 2x100 cpsi Ø90 mm motorsport catalytic converter with heating jacket Ø110 mm and integrated exhaust flaps 2.5" / 63.50 mm, closed without pressure (PLC)
• CARGRAPHIC heating pipe transvers for use with original 3.2 litre blower pipe/heating system
• CARGRAPHIC Sport rear silencer - ‘Banana’ pot with Aeroquip flange with 61 mm internal diameter. Tailpipe outlet on left and right.
• CARGRAPHIC tailpipes Ø76mm welded at a distance of 740 mm CTC

All components were newly installed as part of the project and are precisely tailored to the engine, performance enhancement and vehicle concept.
This creates a self-contained exhaust system that meets the highest standards in terms of both driving dynamics and acoustics.

To the exhaust system...

In combination with MICHELIN Pilot Sport PS2 N4 tyres, a balanced ratio of grip, feedback and driving stability is achieved
precisely tailored to the performance, weight and character of the vehicle.

Complete Wheel Set:

• Front: CARGRAPHIC Racing Rims 8,5×18 – with 235/40ZR18 MICHELIN Pilot Sport 4S N4 tyres
• Rear: CARGRAPHIC Racing Rims 11,5×18 – with 315/30ZR18 MICHELIN Pilot Sport 4S N4 tyres

The CARGRAPHIC Racing rim is a three-piece quality wheel with TÜV certification, 100% made in Germany in our own in-house production facility
and individually configurable in terms of width, offset and finish.

To the Racing Rims for Porsche 911 Carrera...

The standard brake system has been replaced by a CARGRAPHIC sports brake system on the front and rear axles and is consistently designed for high thermal resilience and constant deceleration performance:

• Front axle: 4-piston aluminium monoblock brake calipers with 304 × 32 mm perforated, internally ventilated brake discs
• Rear axle: 4-piston aluminium monoblock brake calipers with 309 × 28 mm perforated, internally ventilated brake discs
• Active brake cooling via air ducts in the front apron
• Steel braided brake lines for a defined pressure point and consistent pedal feel

This combination ensures a clearly defined pedal feel, high stability and superior braking performance –both in sporty road use and when
driving ambitiously.

To the Brake Systems...

The turbo look is complemented by RS 3.0-specific front and rear aprons, which sharpen the motorsport appearance and offer functional advantages.
This combination combines the presence of the turbo model with the purist lightweight aesthetics of the RS 3.0.

A key feature of the RS 3.0 front is the integrated oil cooler box, which not only has a striking appearance but also enables efficient
engine cooling. In addition, integrated brake cooling openings ensure targeted airflow to the front brakes.

The original Porsche RS 3.0 rear spoiler completes the look, consistently continuing the lines of the vehicle and emphasising the balance
between classic motorsport aesthetics and functional aerodynamics. The appearance is rounded off by the twin tailpipes
in the typical RS 3.0 arrangement.

The result is a harmonious, technically sound combination of turbo width and RS character that fits seamlessly into the holistic
concept of the CARGRAPHIC project vehicle.

The vehicle is fitted with RECARO Pole Position bucket seats in black Perlon velour, combined with a specially manufactured
lightweight carpet. The rear seat system was completely removed, and lightweight door panels with characteristic
RS loops as door openers were also used. New red seat belts were fitted to match.

The dashboard and key strips have been renewed and finished in silk matt black. The instrument and switch strips underneath
are made of carbon fibre, sealed with clear lacquer and reduced in functionality. The cockpit is complemented by an original
Porsche 3-spoke steering wheel, completely covered in black Alcantara.

A weight-optimised wiring harness developed specifically for this vehicle reduces unnecessary cables to the technical
minimumand also contributes to weight savings. The result is an interior that is purist, high-quality and consistently focused on the driver.
