R2P High-Performance Turbocharger (300–550 HP, 48mm) – Power for 1.4L-3.0L Engines

The R2P R25-550 is a high-performance turbocharger built for 1.4L to 3.0L engines targeting 300 to 550 HP. Its R-Series aerodynamic geometry and 48mm compressor wheel deliver immediate throttle response and 80% efficiency on the street, track, or in competition.

Features

• R-Series aerodynamic geometry: Maximizes compressor efficiency and improves power delivery from low RPM.
• MAR-M alloy and stainless steel construction: Withstands temperatures up to 1050°C without losing structural integrity or flow.
• Pre-calibrated 0.5 bar actuator: Simplifies installation and ensures precise boost control from first startup.
• Machined speed sensor port: Allows real-time shaft RPM monitoring to prevent overspeed (sensor not included).
• V-Band connections on compressor and turbine: Quick mounting and removal, reliable seal.

Technical specifications

• Power range: 300 – 550 HP
• Compressor wheel inducer: 48 mm
• Compressor wheel exducer: 60 mm
• Turbine wheel dimensions: 76 x 51 mm
• Turbine material: MAR-M alloy (1050°C rated)
• Turbine housing: Stainless steel (A/R 0.72)
• Connection: V-Band (compressor and turbine)
• Maximum speed: 185,000 RPM
• Oil inlet: 7/16-24 UNF
• Oil drain: M14x1.5

Compatibility

This turbo is universal and adapts to high-performance setups in the following displacement ranges:

• Gasoline engines 1.4L to 3.0L
• 1.4L: Street / Track (300-400 HP)
• 2.0L: Time Attack / Street (380-480 HP)
• 3.0L: Drag / Drift (470-550 HP)

Compatible with engine management systems that support variable boost mapping (Stage 2 and Stage 3).

Why choose R2P

Unlike OEM turbos or budget alternatives, the R2P R25-550 uses aerospace-grade components. While conventional turbos lose efficiency at high temperatures, the stainless steel housing and MAR-M wheel maintain structural integrity and consistent flow even above 1000°C, with no performance loss on track or in drag racing.

FAQ

Is professional installation required?
Yes, strongly recommended to ensure proper lubrication, cooling, and system tuning.

Does it include the speed sensor?
The housing is machined to accept it, but the sensor is sold separately.

What maintenance does it require?
Critical to keep oil lines clean and avoid exceeding 185,000 RPM to prevent premature damage.
