ACL Race Bearings

Purpose engineered, ACL race bearings, deliver superior performance drivers expect. Able to endure high RPM conditions, ACL bearings provide more than performance, a piece of mind as well.

available for most popular 4, 6 & 8 cylinder applications

to order please call 631-363-8659 or send inquires to sales AT nolimitmotorsport DOT com


  • High strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
  • Increased crush for improved bearing retention
    Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
  • Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
  • 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
  • Tight consistent wall tolerances to help you maintain consistent clearances.
  • Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.

Kelford Cams – Honda K-series 179-A “Drop-In-Cams”

Acura RSX

Designed specifically for the street enthusiast, the Kelford 179-A series cams provide a significant improvement in horsepower and torque when compared to stock TSX (K24A2) cams, and are designed to use the OEM valvetrain without any upgrades. The primary and intermediate lobes are fractionally larger than the TSX and the main lobe features more area for increased mid-range and top-end performance. Gains of 30+ WHP have been achieved with good quality bolt on parts.

The 179-A lobe geometry requires less valve spring pressure to control the intake and exhaust valves than the stock cams. This means you can rev the 179-A higher than the stock TSX cams without inducing performance-robbing valve float and the more forgiving geometry promotes valve train longevity so you can enjoy the added performance for many miles down the road.

Skunk2’s New Intake Manifold for the 06+ Honda Civic Si

Part #: 307-05-0325

Skunk2 is proud to introduce its Pro Series Intake Manifold for Honda’s ’06-’10 Civic Si in its signature Black Series finish. Similar to Skunk2’s already popular K-series Intake Manifolds, Skunk2’s engineers looked to the popular ’06-’10 Civic Si’s RBC intake manifold for inspiration and went back to the drawing board.

Each of Skunk2’s Pro Series Intake Manifolds for Honda’s K-series engines feature larger plenums and shorter, oversized runners when compared to the RBC, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, Pro Series manifolds were designed for the “street enthusiast” who wants more power but doesn’t want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.

Skunk2’s all-new, cast-aluminum Pro Series Intake Manifolds for Honda’s Civic Si is a direct-fit replacement thanks to their unique throttle body flanges, which are compatible with OEM throttle bodies as well as those as large as 76mm. Pro Series manifolds incorporate an angled-runner design, which allows for additional clearance and include a thermal-insulated gasket for reduced intake air temperatures.

Pro Series Intake Manifolds offer horsepower and torque gains greater than the popular RBC manifold but without compromising mid-range power output. The design incorporates runners that are similar in length to the RBC’s but with larger bores, a special tapered design, as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains. Pro Series Intake Manifold runner exits are also machined and hand-finished to best match the cylinder head’s ports. Skunk2’s Pro Series Intake Manifold’s shape and design also increases wave scavenging effects at the engine’s ideal operating range, which allow for a broad increase in usable power.

Skunk2 is a familiar name in the intake manifold business, with more than 10 years of experience designing, testing, and building them. Similar to OEM manifolds, Skunk2’s Pro Series Intake Manifolds are shell-molded from 356-aluminum, CNC-machined for superior strength, a precise fit, and a high-quality finish, and vacuum-tested for quality. Each manifold is molded with smooth transitions from the throttle body opening to the plenum to the runners with clean parting lines for an optimal finish, both inside and out and features a genuine Skunk2 nameplate.
