This listing is for a RaggDoll series turbo build using a brand new and complete Borg Warner turbocharger as a core. ****
The RaggDoll Velocity turbocharger upgrade is purpose-built for the Porsche 718 Cayman and Boxster T 2.0L engines. As the name suggests, this turbocharger is all about airspeed and instant response. Featuring the latest in turbocharger aerodynamics, the Velocity—like all RaggDoll Turbochargers—delivers legendary performance and reliability for your 718.
When choosing a RaggDoll performance turbo—or any of my components—it all starts with three things:
Each RaggDoll turbo upgrade is designed around a specific power band and performance envelope. One big advantage of the Velocity is that it does not require our high-flow turbo inlet (unlike other models), potentially saving you $780 plus labor. While the high-flow inlet still provides added benefit, this turbo upgrade gives you massive gains right out of the box.
Whether you’re maxing out your stock ECU tune or pushing higher with a custom calibration, the Velocity delivers the performance your 718 Cayman Boxster T 2.0L should’ve had from the factory. It’s built to hit hard, spool fast, and hold power to redline. And yes, paired with our high-flow filter and full exhaust system, this turbo has even more headroom.
The Velocity isn’t just an entry-level turbo—it’s a powerhouse. It’ll even hold its own against its big brother, the RENNEN. This turbo is made for the enthusiast who wants their Cayman or Boxster to stand out and dominate, not blend in with the crowd.

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!
