Porsche 718 Cayman & Boxster Forged Rods & Pistons Upgrade – Engine Build Kit for 2.0T Base & 2.5T S / GTS Models (2017–2024) | RaggDoll Motorsports

Porsche 718 Cayman & Boxster IRP Forged Rods & Pistons

High-Strength Forged Internals for High-Power Porsche 718 Engines

Built for High-Boost Power and Long-Term Reliability

The IRP Forged Rods & Pistons are a complete bottom-end strengthening solution for the Porsche 718 Cayman & Boxster, engineered for high-boost, high-power, and motorsport-level builds. Designed to replace the factory powdered-metal internals, this forged rotating assembly dramatically increases strength, durability, and reliability under extreme cylinder pressures.

This is a foundational engine upgrade for serious Porsche 718 performance builds—built to handle power levels well beyond stock limitations.

Why These Forged Rods & Pistons Exist

The factory Porsche 718 engine internals are optimized for emissions, efficiency, and stock power output. Once boost pressure, ignition timing, or sustained load is increased, the OEM rods and pistons become a critical weak point—especially on tuned or track-driven vehicles.

IRP forged rods and pistons were developed to eliminate these limitations by providing significantly higher tensile strength, improved fatigue resistance, and superior thermal stability. This allows the engine to safely support aggressive tuning strategies, larger turbochargers, and prolonged high-load operation without compromising reliability.

Key Features & Benefits

• Forged Connecting Rods — Substantially stronger than OEM components
• Forged Pistons — Designed for high cylinder pressure and thermal stability
• Increased Power Handling Capacity — Supports high-boost and big-turbo builds
• Improved Reliability Under Load — Ideal for track use and sustained high-RPM operation
• Precision Machining & Balancing — Built for smooth operation and long service life
  

Performance-Focused Engine Internals

Strength Where It Matters Most

Forged rods and pistons are engineered to withstand extreme forces generated by high boost, increased torque, and elevated RPM. Compared to factory internals, forged components offer dramatically improved resistance to bending, cracking, and thermal deformation.

Built for High-Power Porsche 718 Builds

Whether the goal is increased boost on the stock turbo or a fully built big-turbo setup, these forged internals provide the structural integrity required to safely push the Porsche 718 engine beyond factory limits.

Who This Is For

Ideal for Porsche 718 Cayman & Boxster owners building:

• High-boost turbo setups
• Big-turbo or hybrid turbo builds
• Track-focused or endurance-driven cars
• Engines requiring a reinforced bottom end
• Long-term, high-power street builds

This upgrade is intended for serious performance applications—not mild bolt-on setups.

Installation & Build Notes

Professional engine assembly is required.
Installation involves full engine disassembly and machining as needed.

Custom ECU tuning is mandatory after installation. Supporting modifications such as upgraded fueling, turbocharging, intercooling, and engine management should be planned as part of a complete build strategy.

Always consult with RaggDoll Motorsports prior to purchase to confirm compatibility, power goals, and supporting requirements.
