Volvo 16V Exhaust Manifold

2 Years in the Making

Over two years of development and testing, we are currently doing final quality control checks and packaging these manifolds. 

Limited quantity available.

Material Quality

• Constructed from high-quality 347 stainless steel, offering exceptional resistance to heat, corrosion, and thermal fatigue.
• Stabilized with niobium to reduce the risk of cracking ensuring long-term durability.
• Easily weldable for future modifications to wastegate or turbo flanges, adapting to evolving performance needs.

Designed for Optimal Flow and Firing Order

• Optimized for the Volvo redblock firing order, ensuring exhaust pulses merge into the turbo with minimal interuptions from the previous firing cylinder.
• Promotes even scavenging and balanced air-fuel ratios, resulting in smoother, more reliable engine operation.
• Internal runner sized for exhaust velocity while avoiding restrictions or tight-radius bends, preventing the manifold from being the limiting factor in the system.
• The A/R of your chosen turbine housing will be the significant restriction in this system.

Turbo and Wastegate V-Band Fitments

• V-band configuration aligns with modern turbo technology future proofing your investment.
• Compatible with V band Garrett G25, G30, G35 turbos and the GTX30 and GTX35 series or any other turbo using this size flange (Turbosmart, Pulsar)
• Designed to accommodate the largest turbine housing in the G30 range (1.21 A/R) we can provide clearance measurements if you need a larger housing, email us.
• Features a Turbosmart Hypergate WG45 45mm wastegate flange with excelent priority, no boost creep issues here

Spatial Constraints

• Designed for the Volvo B230 engine with B234 16-valve head, utilizing original slanted engine mounts.
• Tested fitment in compact RHD Volvo 240 engine bays, addressing challenges like the strut tower, frame rail, steering linkage, brake booster, oil filter, and alternator.
• Accommodates both 75A alternators (Volvo 240) and 100A alternators (later Redblocks).
• Wastegate placement ensures optimal boost control while maintaining clearance from critical components.
• Compatible with larger engine bays like Volvo 740 and 940 with internally wastegated turbos, we cannot guarantee external wastegate fitment at the moment. also providing decent hood clearance for upright engines
