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.
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.
Street-Driven, Track-Proven Design
With the proper supporting modifications, the RS2 has demonstrated:
Performance is delivered smoothly and repeatably, not at the expense of drivability.
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.
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.
Each RaggDoll RS2 turbocharger undergoes a comprehensive build and validation process:
This process ensures exceptional reliability, smooth operation, and long-term durability.
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.
Liza & most of the time Vince is amazing...lol. Nah, kidding, these guys are awesome folks to deal with. I purchased their Stage 2 turbo, turbo inlet, intercooler, engine tune, and high pressure fuel pump for my 2018 2.5L Boxster GTS and they're products and service have been top notch throughout the entire process.
Raggdoll Motorsports set up two dyno sessions for my Porsche Turbo S. The Porsche touts a 4.0-liter built engine and head work facilitated by Sam at ByDesign. Also has the XR ByDesign turbo kit with all the supporting mods. The first session the PDK kept transitioning out of manual mode. During the second session a boost leak at the throttle body boot ended the session early. We managed 812 hp on a Mustang dyno at only 20 psi of boost.
The people behind RaggDoll Motorsports have been in the game for a very long time and really know their stuff. They have a passion for modifying cars and are enthusiasts before anything else.
I purchased a RENNEN turbocharger for my 718 T. I had a special request, which was to get the turbine housing coated with Swain Tech white lightning thermal barrier coating and RaggDoll accommodated without hesitation even though it was something new for their team.
Hey All! Shout out to Liza and @Raggdolls718. Amazing customer service, product knowledge and a top quality product. Liza went out her way to accommodate my tight timeframe and the level communication and level of detail shared was amazing.
I purchased the Raggdoll Series One turbocharger upgrade and the turbo inlet upgrade from RMS for my Porsche 718 Cayman GTS and was very pleased with both the products and the customer service from RMS!
