CTS Turbo Stage 2 Turbo Upgrade - BMW 335i/335xi/335is (E9X N54)

CTS Turbo's Stage 2 Turbo Upgrade is a standard-size N54 turbocharger kit built for daily-driven power and torque rather than an all-out top-end number. These are brand-new, complete turbocharger units, so there's no core exchange or wait time involved.

The larger compressor and turbine wheels are good for 550-600 hp with a good low-end torque and boost response, per CTS Turbo, without giving up the top end. Flow-optimized exhaust housings and high-efficiency compressor wheels mean less boost is needed to reach those power goals than a stock-frame turbo would require.

Important Compatibility Information

This is a bolt-on upgrade for the BMW 335i, 335xi, and 335is with the N54 engine (E90/E91/E92/E93). It will not fit right-hand-drive vehicles. The kit's 2" turbo inlets require aftermarket 2" inlet piping, which is not included — CTS Turbo's own N54 Intake Relocation Kit is built specifically to pair with this turbo upgrade. Owners looking for more top-end power can also step up to CTS Turbo's hybrid turbocharger upgrades — though on a different platform; see your rep for the correct N54 hybrid option.
