Pure Turbos PURE650 Turbo Upgrade – BMW B58 G-Series (Gen 2)

OVERVIEW

Pure Turbos’ B58 Pure650 for the second-generation B58 BMW platform is the choice for owners who want a meaningful step up in power while keeping close to stock spool and response. It is built on your OEM housing and is available in both 2-port and 6-port configurations.

A Pure Turbos billet compressor wheel, larger and stronger turbine wheel and upgraded bearing housing sit behind a hi-flow 3D printed inlet, and every unit is VSR high-speed balanced. Pure engineered and proved the Pure650 to support 600whp+. On Pure’s own test car, a BMW M340i on an E30 blend with the stock fuel system made 542whp and 731Nm (539 lb-ft).

TECH RESOURCES

Additional Parts Required

• A custom ECU tune is mandatory. Pure Turbos states: “DO NOT WIDE OPEN THROTTLE WITHOUT A PROPER TUNE.” Tune options we stock: MHD Super License for F+G Series B58, bootmod3 B58 tune, JB4 Tuner for B58 Gen1 & Gen2
• New gaskets and O-rings. Pure Turbos: “Always, use new gaskets and O-rings (where applicable).” These are not supplied with the turbocharger.
• Core turbocharger(s) — either ship your factory units to Pure Turbos for the build, or select the refundable core-deposit option and return your cores afterwards. Remove all lines, fittings, actuators and accessories before shipping cores.
• Fueling headroom for the higher power targets: an E85 blend, an upgraded high-pressure fuel pump and/or port injection. The stock fuel system will not reach this turbo’s ceiling on pump gas alone.

Installation

• Pure Turbos installation, pre-lube and break-in procedure (manufacturer FAQ): pureturbos.com/faq — pre-lube the turbocharger through the oil inlet, spin the compressor wheel to coat the bearings, idle 5–10 minutes without revving, then drive on low boost/light throttle until the car is properly tuned
• Pure Turbos core return sheet (PDF): pure-turbos-core-return-sheet.pdf — print it, fill it in and include it with your core shipment
• Professional installation is strongly recommended; turbocharger removal and refitting requires the correct torque specs, clean oil and coolant feed lines and a full oil service.

Notes

• Pure Turbos does not publish an official part number for this upgrade and no SKU is recorded against this listing, so no PART NUMBER section is shown. Confirm the exact configuration with Speed Logic when ordering.
• Confirm whether your car is a 2-port or 6-port B58 before ordering.
