Brian Crower Toyota 2JZGTE Camshafts - Stage 3+ - 276/276 Spec SKU: BRCBC0304

The Brian Crower Toyota 2JZGTE Camshafts - Stage 3+ (276/276), SKU: BRC BC0304 are a very high-performance cam option for the 2JZ-GTE. 

Here are the key advantages, plus important trade-offs to be aware of. 

Top Advantages of the BC0304 Camshafts

1. High Valve Lift (10.29 mm / 0.405”)
   
• These cams provide a very high lift, which means the valves open more. This allows more air (and fuel) to flow into and out of the combustion chamber, which is especially valuable in high-power or high-RPM applications.  
• More lift helps maximize volumetric efficiency when combined with good flow heads, larger turbo, and strong supporting mods.
2. Long Duration (276° Intake / 276° Exhaust)
   
• The “advanced duration” (276°) is quite aggressive. Longer duration keeps the valves open for more of the engine cycle, boosting high-RPM performance.  
• This significantly shifts the power band upward—ideal for race, strip, or drift use where you want strong top-end and sustained high rpm.
3. Race-Spec / Performance-Oriented Profile
   
• Marketed by Crower as a “race spec” cam specifically for “ultimate high performance street / strip / drift” applications.  
• Built for engines with supporting modifications (tuning, ECU, valve springs). It’s not just a mild bolt-on — they assume you will tune the ECU.  
• Because of this, when installed properly, you’ll likely see significantly more peak power or better high-RPM torque than stock or milder cams.
4. Precision Manufacturing
   
• The camshafts are CNC-ground to very tight tolerances (Crower states ±0.02 mm).  
• During finishing, they use small-diameter grinding wheels to create aggressive ramp rates. According to Crower, this “inverted radius” gives faster opening/closing and helps with cylinder filling — more air + more fuel = more power.  
• Each cam is checked on a sub-micron measuring system (Adcole camshaft measuring system) for accuracy.  
• Precision build quality reduces risk of manufacturing defects and ensures consistency, which is very important for high-RPM, high-stress applications.
5. Increased Power Potential
   
• Because of the duration and lift, these cams can support very high power levels — especially useful for turbocharged 2JZ-GTE builds.
• Better airflow at high RPM plus strong valve motion can help you utilize larger turbochargers, more aggressive boost targets, or higher RPM limits.
6. Designed for Forced Induction
   
• Specifically made with turbo (or supercharger) setups in mind. According to the specs, these cams are for 2JZ-GTE (turbo) and other high-performance applications.  
• With proper tuning, they can improve boost response, especially on the top end, and help extract more from your forced-induction setup.
7. Quality + Affordability Trade-off
   
• Crower mentions that by grinding in “high volume,” they can keep costs lower while still maintaining quality.  
• So, for what you’re getting (CNC, dyno-tested profile, race-grade spec), the BC0304 is relatively good value compared to fully custom or extreme specialist cams.

Potential Trade-offs / Considerations (Things to Watch Out For)

• Requires Supporting Mods: Because these are aggressive cams, you must pair them with upgraded valve springs (Crower mandates kit BC0300) to avoid valve float.  
• Tuning Needed: You’ll need ECU tuning / map changes to fully exploit these cams — they’re not plug-and-play “just bolt on” for stock tune.  
• Idle Quality: With very long duration cams, idle might be rougher and “loppier” than milder cams. This is common with race-spec cams.
• Less Low-End Torque: Very aggressive cam profiles often sacrifice some low-RPM torque in favor of high-RPM performance. If you want strong low-end response, this may not be ideal alone.
• Higher Maintenance: More aggressive cams can mean more stress on valvetrain components; check shims, lash, and springs regularly.
• Cost: While reasonably priced for what they are, you’ll pay not just for the cams but also for springs, ECU tuning, and potentially other supporting hardware.

Use-Case Scenarios Where BC 0304 Really Shines

• High-Power 2JZ-GTE Builds: If you’re building a 2JZ for big power (large turbo, high boost) — these cams help you use that airflow more efficiently, especially in the upper RPM range.
• Drag / Strip Cars: Great for cars that spend time at high RPM, where long duration and high lift let you make more power on the top end.
• Drift Cars: In drifting, having strong top-end torque and response can be very beneficial, especially when launching, transitioning, or spinning through RPM.
• High-RPM Engine Builds: If your engine is “built” (forged internals, good head work), and you plan to rev high, these cams will help sustain power at high revs.
