Phantom S1 I6 Twin Turbo (M) Turbocharger
Price pending LP confirmation for this engine variant — B48 reference shown as placeholder.
Real OEM+ power. Stock fit. Serious upgrade.
Phantom takes your engine’s factory turbo and rebuilds it bigger — a true drop-in. No relocated hardware, no exhaust or manifold surgery, no change to how the car looks under the hood. S1 is the quicker-spooling hybrid — faster to its curve, with sharper response and better driveability than the factory unit. S2 is built to make the most power the OEM frame will hold.
How we speak to power
Figures are peak wheel horsepower on pump 93 with the matched tune, drop-in/stock-location, no exhaust/header/install changes. We publish what the frame makes; we don’t inflate it.
Drop-in framing
Everything else on the car stays exactly where BMW put it. No CNC bracket work, no relocated wastegate routing, no “adapter” you have to live with.
S58 — service, not a shelf product
S58 cores aren’t on the salvage market, so Phantom S58 is a build service on your turbos: ship us your two units, we inspect them (and tell you straight if a core isn’t buildable before we charge for it), build, and return your hardware. Turnaround is six weeks barring parts delays.
Select your engine in the variant dropdown — per-engine fitment + price + power range follow. Talk to us for S58 / spec questions.
