Pure Turbos PURE400 (NEW) Turbo Upgrade – BMW 1/2/3/4/5 Series, X1, X2, X3, X4 (B48 Gen 1)

OVERVIEW

The PURE400 (NEW) is a Pure Turbos turbo upgrade for the 2.0L B48 (Gen 1) four-cylinder, built on a new aftermarket housing to the OEM design for a direct-fit installation on the factory turbine manifold. It combines an upgraded billet compressor wheel, a high-flow turbine wheel and an upgraded center housing rotating assembly (CHRA). Pure Turbos rates it as 350+ whp capable, with results depending on fuel and supporting modifications.

Because the housing is new, there is no core exchange and no core deposit; your factory turbo stays with you.

• Turbo gaskets, O-rings, oil and coolant line seals: single-use items that should be replaced during installation. They are not supplied with the turbocharger.
• Supporting fuel system: needed at higher power levels. Confirm your fueling before ordering; we can advise.
