Pure Turbos Stage 2+ Upgrade Turbos – BMW M2 / M3 / M4 / X3 M / X4 M (S58)

OVERVIEW

The Pure Stage 2+ is Pure Turbos' OEM-based turbo upgrade for the S58 engine in the G-Series BMW M2, M3 and M4 and the F97 X3 M / F98 X4 M. Pure rebuilds factory S58 turbochargers with a billet compressor wheel, a high-flow turbine wheel and an upgraded center housing rotating assembly (CHRA), while keeping the OEM housings for a factory-like installation. Pure Turbos rates the upgrade as 900+ whp capable, with results depending on fuel and supporting modifications.

This is a core-exchange upgrade. 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.
