The Skunk2 Alpha Series Intake Manifold is a hallmark product for B-Series engines. Designed with large plenum volume and velocity stacks, it significantly improves high-rpm airflow. Many tuners report gains of 10-15 horsepower on naturally aspirated builds, especially when paired with a performance camshaft and exhaust. The Alpha Series also features a removable secondary plenum for easier maintenance and porting.

Camshafts

Skunk2’s Pro Series Camshafts are available in a range of profiles, from mild street grinds to aggressive race-spec lobes. The Stage 2 camshafts are a favorite among enthusiasts seeking a balance of idle quality and top-end power, while the Tuner Series (Stage 3 and above) require upgraded valvetrain components but deliver substantial peak horsepower. All Skunk2 cams are machined from billet steel and receive a proprietary surface treatment to reduce wear.

Exhaust Systems

The Skunk2 MegaPower Exhaust System is built from mandrel-bent 304 stainless steel and features a straight-through muffler design. It reduces backpressure while maintaining a tone that is aggressive but not obnoxious. MegaPower systems include a full cat-back setup, and many users note improved throttle response and a 5-8 horsepower increase over stock.

Why Choose Skunk2?

Skunk2 appeals to builders who want proven, dyno-tested gains without the premium price tag of some Japanese boutique brands. The company’s extensive catalogs, including intake manifolds, cam gears, valvetrain components, and suspension parts, make it a one-stop shop for many B-Series builds. However, fitment and quality control are occasionally cited concerns on older production batches; Skunk2 has addressed these through updated revision numbers. For the majority of street and weekend track applications, Skunk2 offers exceptional value.

Toda Racing: Precision from Japan

Established in Japan, Toda Racing has built a reputation that extends far beyond its home market. Known for obsessive attention to detail, advanced materials science, and a focus on race-proven performance, Toda parts are often found in professional-level builds where every psi or horsepower counts.

Engineering Philosophy

Toda’s engineering process begins with a deep understanding of mechanical limits. Rather than simply copying OEM designs, Toda develops components from the ground up, using finite element analysis, flow testing, and extensive track evaluation. The company employs proprietary materials—such as heat-treated chrome-moly for rocker arm stoppers and specialized spring alloys for valve springs—that withstand the higher lift and RPM demands of competition engines. Every Toda part is designed to work harmoniously with the engine’s timing and fuel curves, not just as an afterthought.

Camshafts and Valvetrain

Toda Racing camshafts, such as the Spec B and Spec C profiles for B-Series, are legendary among hardcore Honda enthusiasts. The Spec B cam is a popular choice for street/strip setups, offering a broad powerband and improved mid-range torque. The Spec C, with its aggressive duration and lift, is best suited for fully built engines with ported heads and high-compression pistons. Toda also produces race-spec valve springs and titanium retainers that are designed to handle 11,000+ rpm without float—an essential upgrade for high-horsepower builds.

Exhaust Systems

Toda exhausts, such as the Toda Racing Exhaust System, are constructed from high-grade stainless steel and feature a dual-muffler design that reduces noise while maintaining flow. The signature Toda exhaust note is distinct—clean and deep, with a scream at high rpm that many enthusiasts describe as addictive. These systems tend to be lighter than stock and offer measurable gains across the entire rev range.

Intake Components

Toda’s intake offerings include carbon fiber air intakes and velocity stacks that are hand-laid and cured. The Toda Racing Intake Manifold is designed with equal-length runners to optimize individual cylinder filling, and it includes a large-diameter throttle body adapter. While pricey, these manifolds are standard equipment on many time-attack and circuit race cars in Japan.

Why Choose Toda?

Toda is for the serious builder who demands absolute precision and is willing to pay a premium for it. The parts are often more expensive than competitors, but the fitment is consistently impeccable, and the performance gains are repeatable. If you are aiming for a fully built race engine that needs to survive repeated abuse on circuits or drag strips, Toda components are a top-tier choice. Downsides include longer lead times for certain parts and limited availability outside Japan—though many specialty performance shops stock them.

CTS Components: Affordable Performance and Support

CTS Components has grown rapidly in the B-Series community by offering a compelling proposition: performance parts at accessible prices without sacrificing durability. Founded by enthusiasts who identified a gap in the market for affordable turbo kits and intercoolers, CTS now produces a wide array of forced-induction and naturally aspirated upgrades.

Design and Manufacturing

CTS Components leverages modern CAD/CAM processes and outsources manufacturing to select suppliers that meet strict quality standards. Rather than chasing exotic materials for every part, CTS focuses on proven designs—such as cast-turbine housings and bar-and-plate intercoolers—that deliver consistent results. This approach keeps costs down while still providing real performance improvements.
