Pure Turbos PURE900 (NEW) Turbo Upgrade – BMW B58 G-Series (Gen 2)

OVERVIEW

The Pure900 (NEW) is Pure Turbos' largest turbo upgrade for the second-generation (Gen 2) B58 3.0L engine, built on a new aftermarket housing to the OEM design for a direct-fit installation. It uses a billet compressor wheel, a larger high-flow turbine wheel with increased A/R housing ratios and an upgraded center housing rotating assembly (CHRA). Pure Turbos rates it as 800+ whp capable, with results depending on fuel and supporting modifications.

Because it uses a new housing, there is no core exchange and no core deposit. It is offered in 6-Port and 2-Port manifold versions, with an optional T51R inlet modification.

TECH RESOURCES

Additional Parts Required

• Custom ECU tune: required by Pure Turbos for engine safety and to reach the rated power. Tune options we stock: MHD Super License for B58 (F + G Series), Bootmod3 B58 tune, JB4 Tuner for B58 Gen 1 & Gen 2. Pure Turbos considers Bend Calibration's tuning unsuitable for this product and publishes a list of recommended calibrators; ask Speed Logic for a recommendation.
• Vent-to-atmosphere (VTA) catch can: required by Pure Turbos, as the PCV/CCV routing must be changed. The factory EVAP line is no longer used and may be removed or left disconnected. We stock the Black Market Race Gen 2 B58 Catch Can Kit.
• Upgraded intake: recommended by Pure Turbos for best performance; the included silicone inlet adapter is meant to work with the factory airbox.
• Turbo gaskets, O-rings, and oil and coolant line seals: single-use items that should be replaced during installation; not supplied with the turbocharger.
• Supporting fuel system: needed at higher power levels, e.g. an E85 blend with an upgraded high-pressure fuel pump such as the Dorch Stage 2.5 HPFP Upgrade – B58 Gen 2, or a flex-fuel kit such as the MHD FlexFuel Kit (Automatic) – G-Series. Confirm your fueling before ordering; we can advise.

Installation

• 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.
• Pure Turbos does not publish installation instructions or videos for this upgrade; professional installation is recommended.

Notes

• Choose the Turbo Manifold Type that matches your car: 6-Port (2020+ Z4 / M240i / M340i / M440i / X3 / X4) or 2-Port (2020+ Z4 / 540i / 640i / 740i / 840i / X5 / X6 / X7). The two are not interchangeable. Pure's 2-Port label also names the 640i, 740i and 840i, which are not in Pure's fitment guide; contact Speed Logic to confirm fitment for those models.
• The Install Kit option is a Speed Logic add-on; Pure Turbos does not sell an install kit with this turbo. The kit option is labelled "(6-Port)"; confirm with Speed Logic before ordering it with a 2-Port turbo.
• B58 Gen 2 (2020+) only. Gen 1 cars (F-Series 340i / 440i / M240i / M140i and pre-2020 G-Series) take the B58 Gen 1 range.
• Pure also lists the Toyota GR Supra (A90 / A91, 2020–2026) for this turbo; Supra owners should order from our GR Supra listing.
• Pure Turbos includes a limited 1-year / unlimited-mile warranty.
• Legal notice: these parts are for off-road use only and are legal solely for competition racing vehicles as defined under California law. They are not legal for use on public roads.
• Price is for the turbocharger only; labor is not included.
