DNA Motoring TM-B-S-RH Stainless Turbo Manifold
The DNA Motoring TM-B-S-RH is crafted from T-304 stainless steel to meet high-strength demands in boosted B-series applications. Its tubular, equal-length runners help balance exhaust flow across cylinders, which can support more consistent spool and responsiveness. The TIG-welded CNC-machined flange enhances durability against cracking and wear, making it a solid option for street or track setups where reliability matters. This manifold emphasizes robust construction and predictable flow characteristics for a full-race style build.
maXpeedingrods Turbo Exhaust Manifold
The maXpeedingrods manifold is built for B-series applications with a focus on heat resilience and durability. Constructed from sturdy cast iron, it tolerates heat cycling well and resists warping and corrosion over time. The inclusion of a T3 flange provides compatibility with a range of turbochargers, including T3 and hybrid T3/T4 configurations. This option is particularly appealing for builders prioritizing robust material performance and reliable operation in hotter boost environments.
Skunk2 Racing 307-05-0290 Pro Series Silver Intake Manifold (B-Series VTEC)
Skunk2’s 307-05-0290 is a high-end intake manifold designed for B-series engines with VTEC. It features a larger plenum and optimized runners to maximize power gains through improved airflow and venturi effects. While it is not a turbo manifold per se, a well-designed intake manifold is a key complement to a turbo setup, helping to reduce backpressure and improve throttle response at high boost levels.
Skunk2 Racing 307-05-0275 Pro Series Silver Intake Manifold (B-Series Engines)
Another Skunk2 Pro Series option, this intake manifold uses premium A356 cast-aluminum and benefits from a larger plenum and oversized runners. The design aims to improve airflow across a broad rpm range, contributing to enhanced power and throttle response. This manifold is well-suited for naturally aspirated or boosted builds that seek reliable power gains and efficient air delivery to each cylinder.
Skunk2 Racing 307-05-0270 Pro Series Silver Intake Manifold (B-Series Engines)
Skunk2’s 307-05-0270 offers another streamlined path to airflow optimization with a focus on venturi improvements and higher plenum efficiency. It’s positioned as a practical upgrade for B-series engines that aim for improved top-end power while maintaining good mid-range response, particularly when paired with appropriate turbo or boost-friendly calibrations.
Skunk2 Racing 907-05-0010 Ultra Series B Series Ultra Race Intake Manifold Adaptor Gasket
This gasket pack from Skunk2 complements high-performance intake and exhaust work by ensuring proper sealing under higher boost and heat. While not a manifold itself, a quality gasket is essential for preventing leaks that can undermine turbo efficiency and consistency in a full-race B-series build.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Confirm your B-series engine code (e.g., B16, B18) and whether you need a turbo-focused manifold or a compatible intake upgrade to support forced induction.
- Material and construction: Stainless steel offers durability and corrosion resistance, while cast iron can provide heat tolerance. Consider the climate you’ll drive in and the boost levels planned.
- Flange and fitment: Turbo manifolds typically use T3 or similar flanges. Ensure flange type, bolt pattern, and gasket compatibility align with your turbocharger and exhaust system.
- Equal-length vs. equal-flow design: Equal-length runners promote balanced exhaust scavenging, potentially improving spool and response, but installation complexity can vary.
- Performance goals: For turbo builds, prioritize manifolds with proven flow characteristics and durability; for intake components, focus on airflow gains and throttle response.
- Heat management: Consider wrapped manifolds or heat shields to protect surrounding components and improve reliability under boost.
- Installation and maintenance: Some manifolds require welding or additional fabrication. Check for compatibility with your engine bay layout and maintenance access.
- Budget and warranty: High-quality brands often carry better warranties and longer lifespans under boost, but budget constraints may prioritize alternatives with proven track records.
- Balance with other components: A complete setup benefits from matching exhaust, intake, intercooling, and ECU tuning to maximize performance and reliability.
When choosing a full-race B-series turbo manifold or related components, collectors should weigh durability, compatibility, and the intended use—street, strip, or track—alongside the rest of the powertrain. The presented options cover a spectrum from robust stainless designs to high-flow intake pathways, giving builders versatile choices to assemble a coherent turbocharged B-series package that aligns with performance targets and budget.
