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

*This listing is for a RaggDoll series turbo build using a brand new and complete Borg Warner turbocharger as a core. 

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.
