The XS-POWER Stage 3 N55 PWG turbocharger is an upgraded turbo system for compatible BMW N55 applications using the factory-style pneumatic wastegate system. It combines an upgraded compressor and turbine assembly with a high-flow turbo manifold for performance-oriented N55 builds requiring substantially more airflow than the original turbocharger.

The turbo uses a 9-blade Mar-M 246 turbine wheel together with a 7+7 point-milled compressor wheel featuring an anti-surge design. The center section incorporates an upgraded thrust-bearing arrangement, revised oiling system and upgraded bearing housing.

This turbo is intended for properly configured N55 performance builds targeting up to approximately 600 wheel horsepower. Actual output depends on tuning, fuel, engine condition, boost level and the complete combination of supporting modifications.

• High-Flow Stainless Steel Turbo Manifold

Designed for compatible BMW N55 pneumatic-wastegate applications. BMW used different turbocharger and wastegate configurations across N55 production, so model name alone should not be used to determine compatibility.

IMPORTANT: The vehicle must use the compatible PWG / pneumatic wastegate configuration. Some BMW N55 models transitioned to an electronic wastegate system.

Verify the original turbocharger, wastegate configuration, production date and vehicle application before ordering.

The XS-POWER N55 PWG Stage 3 turbo is configured for compatible factory-style oil, coolant, downpipe and charge-pipe connections.

Installation should be performed by a technician experienced with BMW N55 turbocharger systems. All oil and coolant lines, sealing surfaces, intake plumbing and related components should be inspected during installation.

This is an upgraded performance turbocharger and is not intended to produce its full capability on factory engine calibration. Appropriate ECU tuning and supporting modifications are required for the desired boost and power level.

The approximately 600 WHP figure describes the intended capability of a properly configured performance build and is not a guaranteed vehicle output. Actual horsepower, spool characteristics and performance vary according to engine condition, ECU calibration, fuel, exhaust system, intake system, intercooling, boost pressure, environmental conditions and other supporting modifications.

This XS-POWER BMW N55 Stage 3 turbocharger is intended for enthusiasts searching for an N55 PWG turbo upgrade, BMW 335i upgraded turbo, BMW 135i N55 turbo, F30 N55 turbo upgrade, E90 N55 turbocharger, BMW 535i performance turbo, M235i N55 turbo upgrade, or high-flow BMW N55 turbocharger.

Always confirm pneumatic wastegate compatibility before purchasing because BMW N55 turbo systems vary by chassis, model year and production configuration.
