Description
A single-turbo conversion manifold designed specifically around Right-Hand Drive BMW N54 packaging. Replaces the factory twin-turbo arrangement with one Garrett G-Series turbocharger up to G35-1050.
Key Features:
- Designed for RHD, not adapted to it: Most N54 single-turbo manifolds are developed around Left-Hand Drive cars; this one was engineered around RHD packaging from the start.
- Twin-turbo to single conversion: Removes the factory two-turbo arrangement in favour of one modern motorsport turbocharger.
- Sized for G-Series up to G35-1050: Aimed at builds wanting a strong balance of response and real power capability without moving to an unnecessarily large turbo.
- Garrett V-Band inlet: Compatible with GTX35 and G-Series turbochargers.
- 50mm external wastegate port: Designed around the Turbosmart ProGate50, positioned for effective access to exhaust flow through the collector.
- Uses OEM head studs and gaskets: No special fixings needed, though the turbocharger and connection components are sold separately.
Fitment:
- BMW N54 engines, Right-Hand Drive vehicles
- BMW E90, E91, E92, E93
- BMW E60, E61, E82, E88, E71, E89, F01
This is a significant mechanical conversion and Walton strongly recommend professional installation and tuning by a workshop experienced with modified N54 applications. Built to order, typical build time 2-4 weeks.
