Pure Turbos N55 Stage 2 Hybrid Turbocharger Upgrade for BMW E-Series 135i & 335i (E82 E88 E90 E91 E92 E93) Direct-Fit OEM Housing, 500+whp Capable

Pure Turbos Hybrid Upgrade for BMW N55 E‑Chassis 135i and 335i

Unlock serious performance from your 1 Series or 3 Series N55 with this stock-location hybrid from Pure Turbos. Retaining the factory housings for a clean, OEM-style install, this bolt-on unit delivers rapid spool, big power potential and excellent drivability on E82 E88 135i and E90 E91 E92 E93 335i models. If you want a stealthy, factory-fit performance charger that can support well over 500 wheel horsepower with the right setup, this is the proven choice.

We have supplied and fitted these for many MJ Modifications customers and the feedback is consistently outstanding. Strong, repeatable gains on pump fuel, great mid-range punch and reliable operation when paired with sensible hardware and a proper custom calibration.

Why it works

• Genuine stock-location upgrade that supports 500+ whp with suitable ancillaries and mapping
• Factory housings keep it discreet and make installation straightforward for street and track cars
• Fast response for road use with the headroom to turn up the boost on track or strip
• Purpose-built hybrid core rather than a generic CHRA conversion

Core hardware highlights

• Point-milled billet compressor wheel for efficient airflow
• HiFlow turbine wheel to reduce backpressure and improve top-end
• Dual oil seals on both compressor and turbine sides
• Large-diameter 360-degree thrust bearing for durability
• Extensive turbofold machining and port work for optimised flow
• VSR balanced for smooth running and longevity

Real-world results

On typical E-series N55 cars running 93 octane or 99 RON with a quality intercooler, freer-flowing downpipe, upgraded chargepipe, suitable low pressure fuel pump and a custom tune, you can expect around 430 to 480 whp. Well-executed builds have recorded approximately 520 to 523 whp on 135i and 335i setups with the right configuration.

Recommended supporting hardware

• Front mount intercooler
• High-flow or decat downpipe
• Aluminium chargepipe with a reliable valve solution
• LPFP upgrade where required
• Custom ECU mapping by an experienced N55 calibrator
• Highly recommended: Pure Turbos E-Series N55 High Flow Inlet Pipe
