SpeedFactory Titanium VTEC Eliminator Pin Kit for Honda D Series
$44.99
-4 Pins for locking VTEC on all D Series VTEC engines
-Lightweight Titanium, 35% lighter than stock pins (5.8g per rocker assembly)
-VTEC solenoid can be left in place, or a block off plate can be utilized
-LMA’s can be left in place or be removed
Description
These pin kits are designed to be used in drag race applications where the engine is operated at high RPM with limited idle/low rpm use, not in a streetcar.
Gain these advantages:
- Reduced weight in the valve train which helps maintain proper valve motion and reduce the chances of valve float with extreme high RPM use.
- Eliminate the chances of having a wiring or VTEC solenoid related issue that can cause the engine to drop out of VTEC during a run.
- Eliminating the VTEC system function actually increases oil pressure to the engine’s bottom end and camshaft spray bars.
SpeedFactory VTEC Eliminator Pin Kit Installation Notes
Please take care to follow these installation notes – using these guidelines, we have successfully used these locking pin kits for years in our own race cars without issue.
Camshaft Lobe & Rocker Pad Condition:
Make sure these items are in good condition – smooth with no signs of scuffing, scoring, or pitting. If any of these conditions exist you will experience accelerated wear!
Engine Oil:
Running aftermarket camshafts and valve springs with high valve seat pressure and oil that does not have high levels of high-pressure additives such as ZDDP (we recommend an oil with 1200+ppm such as Torco SR-1r, SR-5r, or TR-1r) can wipe out the camshaft lobes and rocker pads. This is not specific to locking VTEC, it happens with normal VTEC system operation as well. We have had good results from 85-100lbs seat pressure on our race cars. Going much higher than that will cause accelerated wear.
Valve Lash:
B & H series – Lash measured at the VTEC lobe needs to be set to 0.006” Intake and 0.008” Exhaust minimum. You can also measure at the valve tip as below.
K,F,D series – Lash measured at the valve tip needs to be set to 0.010” Intake and 0.012” Exhaust minimum.
This is critical! Running tighter lash than this WILL result in premature camshaft lobe and rocker pad wear!
Lost Motion Assemblies (LMAs) & VTEC Solenoid:
LMAs can either be left in place or removed; we have run it both ways successfully. That being said, leaving them in place allows them to act as a “helper” spring, but keeps the rocker pads up against the camshaft’s base circle. Removing the LMAs ensures that the oil film does not get wiped from the base circle which helps alleviate any possible wear issues, so we recommend removing them.
If the VTEC solenoid is installed but not activated it does nothing; functioning the same as an aftermarket VTEC block off plate. You can use either.

The radiator core support must be trimmed, the wiring for the TPS sensor may need to be extended, and clearance between the TPS and radiator hose may require custom upper hose or modification for the radiator. The much anticipated Ultra "Street" Intake Manifold for the '02-'05 Civic Si and '02-'06 RSX/ RSX Type S, and/ or any swap using the K20A/ K20A2/ K20Z1/ K24A1 engines or cylinder heads has finally arrived! The Ultra Series is years of research and development, culminated in a multi-piece cast aluminum intake manifold that offers advantages that only a modular design could allow. Using the latest in CFD (Computational Fluid Dynamics) software; Skunk2 Racing has created a two-piece modular design that allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum lid and optional plenum spacers. In addition to CFD testing, the Ultra Series Intake Manifold has undergone extensive in-house dyno testing which has led to a design that is less restrictive, yielding both torque and power gains well over many of the competitors. Skunk2 Racing Ultra Street Intake Manifolds are cast-aluminum, manufactured from high-grade 356 aluminum alloy for strength and lightweight. Each manifold is CNC-machined for a precise fit, and individually inspected for quality assurance. The Ultra Series Street manifold features a generous 71mm throttle body opening and is constructed with thick walls at entry, minimizing concerns of breakthrough when port matching. Intense planning and design went into the plenum to distribute even airflow to all four cylinders under dynamic load conditions. Placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. Large velocity stack raised bell mouth entries lead to 6.85” long intake runners with smooth transitions allowing the Ultra Street Intake Manifold to really move some air! Skunk2 Racing Ultra Street Intake Manifolds are designed to be used in modified naturally aspirated applications as well as mild turbo/supercharged setups. | More than a decade ago, Skunk2’s engineers looked to the popular Integra Type R intake manifold for inspiration and went back to the drawing board. Skunk2’s Pro Series Intake Manifold for Honda's B-series VTEC engines (GS-R only) features a larger plenum and oversized runners when compared to the ITR manifold for maximum horsepower and torque gains. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, the Pro Series manifold was 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 cast-aluminum Pro Series Intake Manifolds for Honda’s B-series engines are a direct-fit replacement for all B-series engines thanks to three separate flange designs and are compatible with all factory sensors and throttle bodies as large as 75mm. Pro Series Intake Manifolds offer horsepower and torque gains greater than competitors’ manifolds but without compromising mid-range power output. The design incorporates specially tapered runners 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 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. | The much anticipated Ultra "Street" intake manifolds for the Honda B16A/ B17A and B18C engine or VTEC cylinder heads has finally arrived!
