Pure Turbos PURE800 Upgrade Turbo – BMW B58 (F-Series Gen 1)

OVERVIEW

The Pure800 is Pure Turbos' OEM-based turbo upgrade for the first-generation (Gen 1) B58 3.0L engine. Pure rebuilds your factory B58 turbocharger with a billet compressor wheel, a high-flow turbine wheel and an upgraded center housing rotating assembly (CHRA), keeping the OEM housing for a factory-like installation. Pure Turbos rates it as 700+ whp capable, with results depending on fuel and supporting modifications.

This is a core-exchange upgrade. Choose whether to send your factory turbo to Pure first, or pay a refundable core deposit and return your core after your upgraded turbo arrives. For a version on a new housing with no core exchange, see the Pure800 (NEW) B58 Gen 1.

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.
• 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 1.5 HPFP Upgrade Kit – B58 Gen 1 or Dorch Stage 2.5 HPFP Upgrade – B58 Gen 1. Confirm your fueling before ordering; we can advise.
• Core turbocharger: this is a core-exchange upgrade. Send your factory turbo to Pure Turbos first, or pay the refundable core deposit and return your core after the upgrade arrives.

Installation

• Pure Turbos pre-lube and break-in procedure (manufacturer FAQ): pureturbos.com/faq. Pour clean engine oil into the turbo oil inlet and spin the compressor wheel by hand to coat the bearings, then idle 5–10 minutes without revving.
• Pure Turbos core return sheet (PDF): pure-turbos-core-return-sheet.pdf. Print it, fill it in and include it with your core shipment.
• Pure Turbos does not publish installation instructions or videos for this upgrade; professional installation is recommended.
• Before sending your core to Pure, remove all accessories and hardware from it (oil lines, coolant lines, actuators, inlets and similar). Pure discards anything that is not part of the core unit.

Notes

• Send-in option: lead time starts once Pure receives your turbo.
• Core deposit option: the $800 deposit is refunded once your factory turbo is returned to Pure within 60 days of receiving your upgrade.
• The Install Kit option is a Speed Logic add-on; Pure Turbos does not sell an install kit with this turbo.
