Description
A high-mount manifold for big single-turbo BMW S58 builds, intended for G35-size turbochargers and larger. Listed for G87 and G21 chassis, and usable in S58 conversions.
Key Features:
- For G35-size and larger turbos: The choice once an S58 combination has moved past the smaller-frame options and outright airflow is the priority.
- Turbo above the manifold: The high-mount layout gives good access to the turbo and hardware and a practical starting point for the rest of the single-turbo system.
- Seven flange options: Turbosmart Large Frame C / HPT Frame 3, Precision Large Frame and Garrett G40/G42/G45, BorgWarner EFR, Garrett G25-G35, Precision T3 Frame THV, plus T3 and T4 single scroll.
- Turbosmart StraightGate50 wastegate flange: With compatible downpipe, wastegate and S58 turbo oil-line components selectable alongside.
- A fabrication foundation, not a bolt-on kit: Custom downpipe fabrication is required so the exhaust can be built around the turbo, chassis and final spec.
- Lifetime warranty: 304-grade stainless, CFD-optimised cast collector, British-made.
Fitment:
- BMW S58 engines
- BMW G87
- BMW G21
- S58-powered conversion projects where engine-bay packaging allows
Five of the seven flange options share the same price; T3 and T4 single scroll carry a premium. Built to order, typical build time 2-4 weeks.
