Brian Crower Honda Acura B18C/B16A/B17A Camshafts - Stage 2 Boost
Here’s a clear, practical breakdown of the advantages you’d typically see when upgrading to Brian Crower (BC) camshafts on Honda/Acura B-series engines (B16A, B17A, B18C) — especially when paired with Stage 2+ boost (turbocharged or high-manifold pressure builds).
🚗 What “Stage 2 Boost” Means
In Honda performance terms:
- Stage 1 = basic bolt-ons
- Stage 2 = added supporting mods (headwork, intake/exhaust, fueling)
- Boost = forced induction (turbo/supercharger)
In boosted builds, cams that control valve timing and lift become even more critical than in naturally aspirated setups.
🛠️ Key Advantages of Brian Crower Camshafts
🔹 1. Optimized Valve Timing for Forced Induction
BC cams are designed to:
- Reduce valve overlap (less reversion at high boost)
- Improve scavenging and cylinder fill under boost
- Help at mid-to-high RPM, where turbos make power
➡️ Result: Better boost response and usable torque without harmful overlap.
🔹 2. Stronger, More Consistent Lift
- Cam lobes are profiled for precise lift
- Higher/later lift improves airflow
➡️ Especially useful in turbo engines where airflow efficiency is limited by boost pressure — better lift → better combustion
🔹 3. Match to Supporting Mods
Brian Crower offers cams tailored to builds with:
- Ported heads
- Big intake/exhaust
- Upgraded injectors / fuel system
- Turbo manifolds / wastegates
➡️ They work well with supporting parts instead of just being “hotter” than stock.
🔹 4. Improved Midrange & Top-End Power
Compared to stock cams, BC profiles usually help in two major areas:
Midrange (boost builds love this):
- Stronger torque
- Better spool
Top end:
- More airflow
- Higher redline stability
This avoids a common boosted Honda issue where power spikes but is narrow and unusable.
🔹 5. Better Durability & Build Quality
BC is known for solid manufacturing:
- Precision grinding
- Quality heat treatment
- Good surface finish
➡️ That means:
- Longer life under boost
- Reduced wear vs. cheap camshafts
🔹 6. Tunable for Your Power Goals
Brian Crower offers multiple profiles for:
- Street builds
- Street + track
- Full race
This lets you choose a cam that:
- Supports your boost target
- Matches your powerband needs
- Works with your ECU tuning goals

📌 Important to Pair With
To get the most out of BC cams on a boosted B-series:
✔ Boost controller / wastegate
✔ ECU tuning (Hondata/K-Pro/VTEC setup)
✔ Proper fueling (injectors + pump)
✔ Strong head gasket & studs
✔ Exhaust with low restriction
Without tuning and supporting mods, cams alone won’t unlock full gains.
🏁 Summary
Brian Crower B18C/B16A/B17A camshafts in a Stage 2 boost build:
✔ Improve airflow under pressure
✔ Reduce harmful valve overlap
✔ Strengthen midrange torque and top-end power
✔ Are durable and tunable for specific goals
They’re not a magic bullet — but in a well-built boosted Honda/Acura, they’re a meaningful upgrade that improves how the engine breathes and responds.
