Is the Skunk2 Stage 2 Camshaft Kit Your Next Performance Upgrade?

If you own a Honda with a K-series engine and have been looking for a meaningful bump in power, the Skunk2 Stage 2 Camshaft Kit has almost certainly come up in your research. It sits in that sweet spot between a mild daily-driver cam and an all-out race profile, making it one of the most debated upgrades in the Honda tuning community. This article breaks down everything you need to know—real-world power gains, total cost of ownership, installation difficulty, and whether the investment makes sense for your build.

We’ll go beyond the marketing claims and look at dyno charts, supporting modifications you will need, and how this cam kit compares to other options on the market. By the end, you’ll know if the Skunk2 Stage 2 is the right choice for your goals and budget.

What Exactly Is the Skunk2 Stage 2 Camshaft Kit?

The Skunk2 Stage 2 Camshaft Kit is a matched set of intake and exhaust camshafts designed specifically for Honda K-series engines (K20, K24, and K20/K24 hybrid builds). Skunk2 has been a go-to aftermarket brand for Honda performance since the early 2000s, and their Stage 2 cam profile is engineered for engines that have basic bolt-ons but are not yet fully built for forced induction or extreme naturally aspirated setups.

The kit includes two billet steel camshafts, valve springs, and retainers—everything needed to handle the increased lift and duration. The cam profile offers more aggressive timing than Stage 1 cams but remains manageable on the street without requiring an immediate standalone engine management system (though a quality tune is strongly recommended).

Real Power Gains: What the Dyno Tells Us

The headline numbers you see on forums often range from 15 to 25 horsepower at the wheels. But those gains are not automatic; they depend heavily on your engine’s current state. On a stock K24 with only an intake and exhaust, you might see a 15–18 hp gain. On a well-prepped K20 with header, intake, and a quality tune, the gains can exceed 25 hp and be accompanied by a noticeable shift of the power band higher in the RPM range.

Typical Peak Gains

  • Horsepower: +15 to +25 whp (wheel horsepower) depending on supporting mods.
  • Torque: +10 to +15 lb-ft, with a flatter curve that holds torque longer into the rev range.
  • Broadened powerband: The Stage 2 cam shifts peak power about 500–800 RPM higher than stock, but it also improves mid-range pull (3,500–5,500 RPM) compared to more aggressive race cams.

It’s important to note that these gains are realized only after a proper ECU calibration. Without tuning, you will likely lose power and risk engine damage. If you plan to install this cam kit, budget for a dyno tune or at least a well-calibrated base tune from a trusted Honda tuner.

Effect on Daily Drivability

One common concern is whether a Stage 2 cam makes the car annoying to drive in traffic. In our opinion, the Skunk2 Stage 2 strikes a good balance. You will have a lumpy idle that announces the cam, but it is not rough enough to cause stalling or surging. Low-RPM torque below 2,500 RPM does soften slightly, but it remains acceptable for daily driving. If you spend a lot of time in stop-and-go traffic, consider that trade-off. For most enthusiasts, the slight idle personality is a feature rather than a bug.

Total Cost: Beyond the Kit Price

The Skunk2 Stage 2 Camshaft Kit itself typically retails between $500 and $700, depending on your supplier and whether you catch a sale. But the true cost of the upgrade includes several additional items that are easy to overlook.

Cost Breakdown for a Typical Install

ItemEstimated Cost
Cam kit (cams, springs, retainers)$500 – $700
Installation labor (shop rate 4–6 hours)$300 – $600
ECU tune (dyno or remote)$400 – $800
Supporting parts (gaskets, timing chain tensioner, fluids)$100 – $250
Optional: upgraded valve retainers for high RPM$100 – $200
Total estimated project cost$1,400 – $2,550

DIY installation can save you $300–600 in labor, but this is not a beginner-friendly job. Timing errors can destroy your engine. If you are experienced with K-series timing and have the specialty tools (cam gear holder, torque wrench for cam caps, etc.), you can cut costs. Otherwise, paying a professional is worth the peace of mind.

Are There Cheaper Alternatives?

Yes, you can find budget camshafts from other brands like K-Tuned or even used OEM cams from a higher-performance Honda. However, Skunk2’s reputation for consistent metallurgy and precise lobe profiles justifies the price premium for many enthusiasts. Skimping on cam quality can lead to valvetrain noise, premature wear, or even catastrophic failure at high RPM. If you are building for reliability and performance, Skunk2 Stage 2 is a solid investment.

Installation: What You Need to Know

Installing the Skunk2 Stage 2 camshaft kit requires removing the valve cover, timing chain, and cam gears. You do not need to pull the engine, but you must be comfortable working inside the engine bay of a front-wheel-drive Honda (tight clearance on the driver side).

  1. Disconnect the battery and drain coolant if needed for access.
  2. Remove the intake manifold and valve cover (some shops skip intake removal, but it makes cam removal easier).
  3. Set the engine to top dead center on cylinder #1 (TDC compression stroke).
  4. Remove the timing chain tensioner and cam chain guides.
  5. Remove the cam gears (mark or note positions for reinstallation).
  6. Replace old camshafts with new Skunk2 units, using supplied valve springs and retainers.
  7. Reinstall timing chain, tensioner, and guides. Verify timing marks.
  8. Reassemble intake manifold, valve cover, and accessories.
  9. Prime oil system before starting the engine.
  10. Load a base tune or drive immediately to a tuner.

Important: Even if you don’t plan to track the car, the included Skunk2 valve springs are mandatory. The Stage 2 cam’s higher lift can cause valve float on stock springs above 7,000 RPM. The springs also require shimming to the correct installed height—something a good shop will verify.

Common Installation Mistakes

  • Reusing the old timing chain tensioner (replace it; they are known to fail).
  • Not replacing the front main seal while everything is apart (cheap insurance).
  • Incorrect cam gear indexing (results in poor power or timing chain noise).
  • Overtorquing cam cap bolts (can crack the head).

Who Should Buy the Skunk2 Stage 2 Cam Kit?

This cam kit is not for everyone. It makes the most sense if your engine already has basic bolt-ons—intake, header, exhaust—and you are chasing that next tier of naturally aspirated performance. If you plan to add forced induction later, a Stage 2 cam may still work with a turbo or supercharger, but many builders prefer a milder cam to avoid excessive overlap that wastes boost.

Ideal Candidate

  • K20A2, K20Z3, K24A2, or K24A4 engine
  • Already has an intake, 4-1 header, and 2.5-inch exhaust
  • Willing to invest in a professional tune ($400+)
  • Comfortable with a slightly rougher idle and higher cruising RPM
  • Budget of at least $1,500 for the full project
  • Stock engines without any breathing modifications (gains limited, risk of pinging).
  • Drivers who want a fully stealth daily driver with no idle change.
  • Budget builders trying to cut corners on tuning or supporting parts.

How It Stacks Up Against Competitors

Skunk2 Stage 2 competes directly with Brian Crower Stage 2 and K-Tuned Stage 2 camshafts. On a K24 with similar supporting mods, all three deliver comparable peak power. Brian Crower cams tend to cost slightly less but may have less consistent spring pressures out of the box. K-Tuned cams are known for smoother idle character. Skunk2 holds the edge in high-RPM stability, as their valve spring packs are very reliable. For hard track use, Skunk2 is often the #1 choice among Honda specialist shops.

Frequently Asked Questions

Do I need to upgrade the fuel injectors?

No, not for a naturally aspirated Stage 2 cam setup. Stock injectors can handle the increased airflow until you exceed roughly 230 whp. If you later add a larger throttle body or intake manifold, injectors may become necessary.

Will it pass emissions?

This depends on your location and the tune. The cam itself does not change emissions drastically if tuned correctly, but a modified ECM calibration can fail visual inspection in some states. Cold air intake and header are more likely to cause emissions issues than the cam profile.

Can I install this cam without a tune?

Technically yes, but you will gain almost no power and risk damaging your engine. The stock ECU cannot compensate for the altered timing and airflow. Running without a tune often results in a lean condition that can burn valves or melt pistons. Do not skip the tune.

Final Verdict: Worth It for the Right Builder

The Skunk2 Stage 2 Camshaft Kit is not a budget upgrade, but for the enthusiast who can afford a complete package—cam kit, supporting parts, and professional tuning—the return on investment is strong. You get a proven power gain, excellent valvetrain components, and a driving experience that feels significantly more alive without sacrificing daily usability.

If your goal is a well-rounded, naturally aspirated K-series build that can hang with higher-displacement cars on the track or the street, the Skunk2 Stage 2 should be at the top of your list. Just remember to account for the full cost and to trust the install to someone who knows K-series timing inside and out. When done right, this kit transforms your Honda from a peppy economy car into a serious performance machine.
