About the BMW 335i Engine
Our BMW 335i engines for sale stand out due to their proven Inline-6 turbocharged architecture, offering exceptional power, responsiveness, and aftermarket support. Known for their tunability and high performance, both the N54 (twin-turbo, 2007-2010) and N55 (single twin-scroll turbo, 2011-2013) engines deliver an exhilarating driving experience that defined the BMW 335i reputation as the enthusiast choice in the late-2000s through mid-2010s 3-Series lineup. If you are seeking a top-notch 335i engine for sale that enhances your vehicle performance, both the N54 and the N55 are excellent choices depending on your priorities.
The N54 vs N55: Which Engine Is in Your 335i
Confirming whether your 335i uses the N54 or the N55 is essential for proper engine sourcing:
| Option | Description |
|---|---|
| N54 (2006 to 2013 production) | Twin parallel turbochargers. Direct Injection. No Valvetronic. Used in BMW 335i 2007-2010 (E90/E91/E92/E93 pre-LCI), 135i (E82/E88), X6 xDrive35i (E71), Z4 sDrive35i (E89), 335is (2011-2013), 1M Coupe (2011). The tuner favorite, capable of 500+ HP on stock internals with aftermarket support. |
| N55 (2009 to 2017 production) | Single twin-scroll turbocharger. Direct Injection. Valvetronic variable valve lift. Used in 335i LCI 2011-2013 (E90/E92/E93), plus numerous other BMW models including 535i (F10), X3 xDrive35i (F25), X5 xDrive35i (F15), 640i (F12/F13), 740i (F01), 1-Series M variants. More reliable HPFP than N54, smoother daily driving, less aftermarket tuning headroom on stock internals. |
Both engines share the same fundamental architecture: 3.0L Inline-6, 84.0mm x 89.6mm bore and stroke, 10.2:1 compression, Direct Injection, DOHC 24-valve, Double-VANOS. The differences are turbocharger configuration and the addition of Valvetronic on the N55.
The BMW Inline-6 Family Position
The N54 and N55 occupy a critical transition position in the BMW Inline-6 lineage. The full family that buyers should understand:
- M54 (2000-2006, our vaz86 listing): Naturally aspirated, Double VANOS, aluminum block with cast iron liners. The last great BMW NA inline-6.
- N52 (2006-2011): Naturally aspirated successor with magnesium/aluminum composite block, Valvetronic.
- N54 (2006-2013, THIS LISTING): First turbocharged modern BMW Inline-6, twin parallel turbochargers, no Valvetronic.
- N55 (2009-2016, THIS LISTING): Single twin-scroll turbocharger, adds Valvetronic, simpler turbo architecture.
- B58 (2015-present, our vaz78 listing): Closed-deck block, forged crank, “the modern 2JZ”, current production turbocharged Inline-6.
The N54 and N55 are the bridge between naturally aspirated BMW Inline-6 character (M54) and the modern closed-deck B58 era. The N54 is the enthusiast favorite for tunability (500-plus HP on stock internals documented with aftermarket support); the N55 is the daily driver favorite for refined operation, better HPFP reliability, and Valvetronic efficiency.

Two different turbocharger configurations and the Valvetronic addition. The N54 (2006-2013 production) uses twin parallel turbochargers, Direct Injection, Double VANOS, and does NOT have Valvetronic. The N55 (2009-2017 production) uses a single twin-scroll turbocharger, Direct Injection, Double VANOS, AND adds Valvetronic (variable valve lift on the intake camshaft). Both share the same fundamental architecture: 3.0L Inline-6, 84.0mm x 89.6mm bore and stroke, 10.2:1 compression, DOHC 24-valve. The N54 is the enthusiast favorite for tunability (500-plus HP on stock internals documented); the N55 is the daily driver favorite for refined operation, better HPFP reliability, and Valvetronic fuel economy.
Year-dependent for the E90/E91/E92/E93 platform. The 335i sedan/wagon/coupe/convertible (E90/E91/E92/E93) used the N54 from 2007-2010 (pre-LCI) and the N55 from 2011-2013 (LCI). The 135i (E82/E88) used both N54 (early) and N55 (later). The 335is (2011-2013) used the N54 in a high-output calibration. The 1M Coupe (2011 only) used the N54 in its highest-output factory calibration. The X6 xDrive35i (E71) used both N54 and N55 across its production run. The Z4 sDrive35i (E89) used the N54. We confirm the engine family on every order; tell us your VIN or year/trim and we will match the correct N54 or N55.
The #1 N54 known service item. The High-Pressure Fuel Pump (HPFP) on the N54 is mechanically driven by the engine camshaft and delivers fuel at high pressure (up to 2,900 psi) to the Direct Injection injectors. The original-spec HPFPs on early N54 production had a known failure mode where the pump would fail to maintain the required fuel pressure, causing limp mode, misfire codes, and rough running. BMW issued multiple HPFP service campaigns and extended warranty coverage on N54 HPFPs. By the later production years, the HPFP was redesigned with improved durability. The N55 HPFP is generally more reliable than the early N54 HPFP. We document HPFP condition on every N54 and N55 we ship and disclose any concerns.
335i pre-LCI, 135i, X6 35i, Z4 35i, 335is, 1M. The N54 was used in: BMW 335i E90 sedan, E91 wagon, E92 coupe, E93 convertible (2007-2010 pre-LCI); BMW 135i E82 coupe and E88 convertible (2008-2013); BMW X6 xDrive35i E71 (2008-2014); BMW Z4 sDrive35i E89 (2009-2016); BMW 335is high-output (2011-2013); BMW 1M Coupe (2011 limited edition); Alpina B3 (2007-2013, N54-based with Alpina turbocharger and tuning); and Wiesmann GT MF4 (niche application). All use the same fundamental N54B30 with calibration variations.
335i LCI, 135i late, X3 35i, X5 35i, 535i, 640i, 740i, and many more. The N55 was used in a much wider range of BMW models than the N54: BMW 335i E90/E91/E92/E93 LCI (2011-2013); BMW 135i late production (2012-2013); BMW X3 xDrive35i F25 (2011-2017); BMW X5 xDrive35i F15 (2014-2018); BMW 535i F10 (2011-2017); BMW 640i F12/F13 (2012-2018); BMW 740i F01 (2013-2015); BMW Z4 sDrive35is E89 high-output (2011-2016); various other 35i-badged BMWs. The N55 is the dominant pre-B58 turbocharged BMW Inline-6 and you encounter it across the full BMW lineup from the early 2010s.
Yes, the N54 is one of the most tunable modern BMW engines. The N54 is widely regarded as one of the most tunable modern BMW engines, with strong aftermarket support across tuning software (JB4, COBB, MHD, BM3), upgraded HPFP, larger injectors, upgraded turbos (single-turbo conversions, larger twin turbos), upgraded intercoolers, charge piping, and supporting fueling. Stock-internal N54 builds with conservative tuning routinely make 400-500 HP. Aggressive single-turbo conversions on stock internals have been documented at 700-plus HP. Built engines with upgraded internals reach 1,000-plus HP. The N55 has less tuning headroom on stock internals than the N54 due to the single twin-scroll turbo geometry and Valvetronic complexity. For maximum tuning headroom, the N54 is the choice.
Bridge generation between NA M54 character and modern B58 turbocharging. The M54 (our vaz86 listing) is the last great BMW naturally aspirated Inline-6 (2.2L, 2.5L, 3.0L variants, 170-231 hp, Double VANOS, no Valvetronic). The N52 (2006-2011) is the direct NA successor with Valvetronic. The N54 introduced turbocharging to the modern BMW Inline-6 with twin parallel turbos. The N55 simplified to single twin-scroll and added Valvetronic. The B58 (our vaz78 listing, 2015-present) is the closed-deck successor that earned the modern-2JZ comparison. The N54/N55 occupy the critical 2007-2017 turbocharged generation between the M54 NA era and the B58 modern era.
No. There is no core return required.

Got an N54 for a 2008 BMW 335i E92 Coupe replacement. Engine family correctly identified as N54 (NOT the later N55), all 6 cylinders compression tested, both turbochargers verified, HPFP condition documented up front (the #1 N54 service item). Honest pre-purchase information about the N54’s tunability advantage (500-plus HP on stock internals) and the BMW Inline-6 lineage (M54 per vaz86 → N54/N55 per this listing → B58 per vaz78).
Cordelia M. –
Sourced an N55 for a 2012 BMW 335i LCI replacement. Engine family correctly identified as N55 (the LCI generation, NOT the earlier N54), single twin-scroll turbo verified, Valvetronic function confirmed (N55-specific). Honest pre-purchase information about the N55 vs N54 distinction and the recommended cooling system service at install given BMW’s known plastic component fragility.
