Pure Turbos Stage 2 Upgrade Turbo – BMW B46 / B48

OVERVIEW

The Pure Stage 2 is Pure Turbos' OEM-based turbo upgrade for the BMW B46 / B48 2.0L four-cylinder. Pure rebuilds your factory turbocharger with its own billet compressor wheel and a larger high-flow turbine wheel, with an upgraded thrust system, and keeps the factory housing so the turbo installs in the stock location.

This is a core-exchange upgrade. Choose whether to send your factory turbo to Pure first, or pay a refundable core deposit for a B46 or B48 core and return your core after your upgraded turbo arrives.

• Pure Turbos billet compressor wheel

Additional Parts Required

• Turbo gaskets, O-rings, oil and coolant line seals: single-use items that should be replaced during installation. They are not supplied with the turbocharger.
• Supporting fuel system: needed at higher power levels. Confirm your fueling before ordering; we can advise.

Installation

• Pure Turbos does not publish installation instructions or videos for this upgrade; professional installation is recommended.
• Pure Turbos installation, pre-lube, break-in and core-return guide (PDF): pure-turbos-install-and-break-in-guide.pdf. Pre-lube the turbocharger through the oil inlet, idle 5–10 minutes without revving, then drive on low boost / light throttle until the car is properly tuned.
