Fastest Spooling VTG Hybrid for the 718 2.5L S & GTS

The RaggDoll Series oNe is our original powerhouse — a lightning-fast spooling, track-proven hybrid turbocharger based on the G30-660. 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.

Designed for both street and circuit performance, the Series oNe can deliver over 500 wheel horsepower with supporting mods and still offers the fastest spool in its class — hands down. From autocross to time attack, this is the turbo you want if throttle response and predictability matter more than just big dyno numbers.

Key Features:

• Direct bolt-on VTG hybrid turbo — no modifications required
• Based on Garrett G30-660 architecture for track-ready flow and fast response
• Custom-designed RaggDoll compressor wheel for superior midrange power and throttle control
• Matched to Borg Warner’s high-efficiency turbine for rapid spool and thermal stability
• Inconel turbine material rated to 1050°C / 1922°F for sustained abuse
• Outflows stock and aftermarket competition while spooling noticeably faster
• 20% more peak horsepower over the factory S turbo
• Cooler IATs at higher power levels thanks to more efficient wheel geometry
• Engineered for stable, predictable boost behavior — no unexpected lag or surging
• Built with track feedback — over 100 R&D hours dedicated to real-world testing

Why Choose the RaggDoll Series oNe?

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 model owners wanting a big performance jump without sacrificing spool or street manners. GTS owners looking to go even further than a 20% increase in power can step up to our Series Two — 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 VTG turbo upgrade. Simply transfer your OEM wastegate and VTG 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.

Our Proprietary Compressor and Turbine Pairing

• Advanced, High-Flow Compressor Wheel: Designed to maximize efficiency and mass airflow without the surge or lag of older designs.
• High-Flow Turbine Wheel: Perfectly matched to the compressor to deliver superior turbine-to-compressor flow balance.
• Race-Ported and Extrude Honed Housings: Complements the wheel designs to unleash every ounce of power potential.

We strongly recommend pairing the RaggDoll Series oNe with the RaggDoll High-Flow Turbo Inlet to allow the turbo to breathe to its full potential.

THE PROCESS
All 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 Turbocharger’s 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 Turbocharger’s come with a new exhaust housing gasket. 

*We also offer new Borg Warner turbochargers with our wheels as an option
