Walton Motorsport N54 Single Turbo Manifold for N54-engined right-hand drive E8X 135i and E9X 335i, as well as 1M Coupe.

The BMW N54 came fitted with a pair of small turbos and though great for response and upgradeable to a point with hybrid turbos, eventually the standard cast manifold design becomes a flow restriction – this restricts power and increases harmful backpressure. This is where Walton Motorsport step in – with years of motorsport turbo manifold design behind them, they have been able to create a super-efficient single turbo manifold with a Garrett V-band for GTX35 and G-Series compatibility. The result is a huge increase in efficiency, power and outright performance up to and over 1000bhp.

• Carefully selected 304 stainless steel tube. Working to eliminate the risk of material failure
• Fully purge-welded. Subsequently improving gas flow leading to increases in power and lowered response times
• Ported merge collector, welded internally and externally. This results in high strength, durability and turbo lifespan
• Fully-smoothed head ports designed to optimize gas flow, resulting in an increase of power and lowered response times
• Optimized for use with  Turbosmart Gen-V Power Gate 50 Wastegates
• Lifetime Warranty against manufacturing faults and defects

This manifold no longer has placement for pre-turbo lambda sensors and so aftermarket management such as Syvecs is strongly advised.

This listing is for the manifold only. Turbo kits available by request. Made to order with a lead time of 2-3 weeks.
