The RaggDoll Series One is our original powerhouse — a lightning-fast spooling, track-proven hybrid turbocharger. Engineered specifically for the Porsche 718/982 Cayman and Boxster S & GTS 2.5L engines, this unit is built to dominate your favorite canyon route or road course, all while maintaining factory-like drivability.
The RaggDoll Series One delivers over 500 wheel horsepower with the right supporting mods while still offering the fastest spool in its class, hands down. Although it was buily to flow over 60 lb/min, we built it to be optimized at 440 to high-400s at the wheels effortlessly, all while keeping intake temps in check. It’s not just about power, especially with our platform it’s about keeping those air intake temperatures down. And one way to do that and make your intercoder work a lot less harder is have the right turbo for the power that you desire.
You track guys asked — we delivered.
The RaggDoll Series oNe was born from motorsport experience and customer demand. It’s the perfect upgrade for S and GTS 2.5 model owners wanting a big performance jump without sacrificing spool or street manners. If you’re one of those Cayman Boxster 2.5L motor owners looking to go even further than a 30% increase in power can step up to our RS2 RaggDoll Motorsports Series Two turbo upgrade— but if you want maximum punch with the quickest response possible, this is your turbo.
No Guesswork — Just Performance
This is a true plug-and-play VGT turbo upgrade. Simply transfer your OEM wastegate and VGT module (three screws) to the new unit. We do this to avoid damage during shipping and ensure you keep your known-good components — no random electronics, no mystery parts.
Whether you’re setting lap records or chasing down supercars on the freeway, the RaggDoll Series oNe is the lightweight fighter with a heavyweight punch.
We strongly recommend pairing the RaggDoll Series oNe 718 turbo upgrade with the RaggDoll High-Flow Turbo Inlet to allow the turbo to breathe to its full potential.
Our core exchange RaggDoll Series turbochargers are remanufactured* to stock specifications and tolerances. With all hard parts to include the center cartridge and housings being retained.
When a turbocharger comes in for rebuild it is disassembled, cleaned and inspected for any damage or possible issues. We then do all machine work necessary to the housings depending on what turbocharger upgrade you requested. We dynamically balance the turbine wheel independently and the compressor wheel independently then after we replace all cartridge bearings, washers, seals and thrust we reassemble and balance a 3rd time at 250,000 rpm with our VSR machine as a complete cartridge assembly. The compressor housing is stripped bare and laser etched with the RaggDoll turbo series identification matching your internal parts.
The RaggDoll Series Turbochargers are immediately separated from the rest. You know you’re installing something next level and top shelf performance. From the moment of unboxing our turbos you’ll notice they look different than the rest because they are different from the rest.
All RaggDoll Series Turbochargers come with a new exhaust housing gasket.
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!
