Turbo Manifold – Nissan RB – High Mount – Big Turbo (1000HP Plus)

£1,392.00

This is the big dog of the Nisan RB high-mount game. Built for serious flow, serious boost, and serious power — the Walton Motorsport High Mount Big Turbo Manifold is designed for turbochargers like the G40, G42, Precision 7675+, Borg Warner S300 series, and beyond. Whether you're chasing 1000HP+ or just want every last PSI on the table, this is the manifold that delivers.

Previously known and still referred to as our “Nissan RB Type B” manifold, this configuration has now been renamed for clarity and customer confidence — same race-proven performance! The Type A Manifold is still available and suits lower HP goals of 'Up to 1000HP' with a tighter fitment envelope...

Built for Boost. Engineered for Precision.

This isn’t a universal flange collector tacked to some tubes — it’s a CFD-optimised, dyno-tested, track-proven system designed to:

Feed large-frame turbos with uninterrupted exhaust energy

Prioritise wastegate flow to avoid boost creep

Withstand heat cycles and abuse that would destroy lesser gear

Our proprietary cast collector is at the heart of the system — not just strong, but smart. It handles gas velocity and merges pulses in a way that actually supports power rather than disrupting it.
