Porsche 718 Cayman & Boxster Turbocharger Upgrade – RaggDoll RS2 Turbo (2.5L S & GTS, 2017–2024)

Built to Dominate on Track and Street

The RaggDoll Motorsports RS2 Turbocharger is a no-compromise performance turbo upgrade for the Porsche 718 Cayman & Boxster 2.5L S and GTS models (2017–2024). Engineered through extensive real-world testing, the RS2 delivers exceptional spool response, massive midrange torque, and sustained top-end power — all while retaining OEM-like drivability and reliability.

This is not a mild enhancement or incremental upgrade.
The RS2 represents the pinnacle of RaggDoll Motorsports turbo development for the 2.5L platform, delivering performance comparable to far higher-tier models while preserving the refined driving character Porsche owners expect.

Meet the RaggDoll RS2 Turbocharger

The RS2 is a plug-and-play performance turbo built using genuine BorgWarner VGT housings and upgraded with RaggDoll’s proprietary compressor and turbine pairing. The result is a turbocharger that delivers quick throttle response, strong torque across the rev range, and relentless pull at high RPM.

Equally capable on the street or at the track, the RS2 is designed to feel composed and predictable under all driving conditions—brutal when pushed, refined when cruising.

Key Features & Highlights

• Direct Plug-and-Play Fitment - Retains OEM BorgWarner VGT housing for factory-style installation
• Custom High-Flow Compressor Design - Modern aerodynamic profile for increased mass airflow and efficiency
• Proprietary High-Efficiency Turbine System - Optimized for fast spool and strong top-end breathing
• Inconel Turbine Wheel - Rated for sustained exhaust temperatures up to 1050°C / 1922°F
• Predictable, Linear Boost Delivery - Strong response without surge or erratic boost behavior
• Improved Thermal Efficiency - Lower intake air temperatures under boost
• Extensive Validation - Over 100 hours of dyno, Dragy, and real-world testing

Street-Driven, Track-Proven Design

Proven Performance Capability

With the proper supporting modifications, the RS2 has demonstrated:

• 500+ wheel horsepower on pump gas (93 octane)
• Approaching 600 wheel horsepower on race fuel, water-methanol injection, or full E85 setups
• Spool characteristics that rival—or exceed—factory response
• Consistent performance trusted by experienced builders, tuners, and competitive drivers
  

Performance is delivered smoothly and repeatably, not at the expense of drivability.

Why the RS2 Was Built

The factory turbocharger has clear limits. Early upgrades pushed the platform forward—but the RS2 was designed to go further.

Every aspect of the RS2 was developed with a single objective: maximum usable power. From canyon driving to track days to high-speed pulls, the RS2 provides relentless acceleration while maintaining the refined behavior expected from a Porsche 718.

This turbocharger is built for drivers chasing lap times, real-world speed, or outright performance records—without turning the car into a compromise.

Proprietary Compressor & Turbine Pairing

The RS2 features a carefully engineered compressor and turbine combination designed to operate as a balanced system. After multiple housing revisions and internal flow refinements, the RS2 is capable of over 70 lb/min of airflow, while maintaining precise boost control and efficiency.

Every modification serves a single purpose:

Delivering the highest level of usable performance possible.

To fully unlock the RS2’s potential, pairing with a high-flow turbo inlet and upgraded high-pressure fuel system is strongly recommended.

The RaggDoll Build Process

Each RaggDoll RS2 turbocharger undergoes a comprehensive build and validation process:

• Complete disassembly and inspection
• Precision machining of factory VGT housings
• Independent dynamic balancing of compressor and turbine wheels
• Full cartridge assembly with upgraded internals
• Final high-speed VSR balancing at over 250,000 RPM
  

This process ensures exceptional reliability, smooth operation, and long-term durability.

What Makes the RS2 Different

• Laser-etched RaggDoll identification on every compressor cover
• Built from genuine BorgWarner cores—not offshore castings
• Race-tested, tuner-approved configuration
• Supplied with a new exhaust housing gasket
• Optional new BorgWarner unit with RaggDoll internals available

Why Choose RaggDoll Motorsports

The RaggDoll Motorsports RS2 Turbocharger is more than a power upgrade—it’s a performance statement. Designed for drivers who refuse to settle, the RS2 delivers record-level capability, exceptional response, and uncompromising execution.

Track-built. Street-refined. Proven where it matters.

This is the edge.
