Pure Turbos Stage 2 Upgrade Turbos – BMW N63 / N63tu

OVERVIEW

The Pure Stage 2 is Pure Turbos' OEM-based turbo upgrade for the N63 and N63TU 4.4L twin-turbo V8 used in the F-Series 5, 6 and 7 Series, the E70 / E71 and F15 / F16 X5 and X6 xDrive50i, and the F01 / F02 ALPINA B7. Pure rebuilds the factory turbochargers with a billet compressor wheel, a larger high-flow turbine wheel and an upgraded bearing housing, and keeps the OEM housings for a factory-like installation.

This is a core-exchange upgrade. Choose your engine (Non-TU, TU or ALPINA B7), then choose whether to send your factory turbos to Pure first or pay a refundable core deposit and return your cores after your upgraded turbos arrive.

Installation

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