Brian Crower Stage 3 Camshafts – 272° Spec | Toyota 2JZ-GE | IS300 / GS300

Take your naturally aspirated 2JZ-GE build to the next level with Brian Crower Stage 3 272° Camshafts — a significant camshaft upgrade engineered for the Toyota 2JZ-GE as found in the Lexus IS300 and GS300. The Stage 3 272° specification delivers increased duration and lift over the factory camshafts, extending the engine’s power band higher into the RPM range and unlocking the high-revving potential that the 2JZ-GE’s robust bottom end is capable of supporting. A critical component for any serious naturally aspirated 2JZ-GE performance build.

Key Features:

• Stage 3 specification — Brian Crower’s performance camshaft grind designed for high-performance naturally aspirated 2JZ-GE applications
• 272° duration — increased camshaft duration over factory specification for extended valve opening and improved high-RPM breathing
• 2JZ-GE specific — engineered for the naturally aspirated 2JZ-GE as used in the Lexus IS300 (JCE10) and GS300 (JZS160)
• Brian Crower quality — manufactured to Brian Crower’s motorsport-grade standards with decades of professional racing application
• Sold as a set — includes both intake and exhaust camshafts for a complete camshaft upgrade
• Drop-in compatible — designed for installation in the factory 2JZ-GE cylinder head

Performance Benefits:

• Extended High-RPM Power Band: 272° duration keeps the intake and exhaust valves open longer, improving cylinder filling at high RPM and extending the engine’s power band further up the rev range
• Increased Peak Power: Improved high-RPM breathing translates directly into increased peak power output — the primary goal of a camshaft upgrade on a naturally aspirated engine
• Improved Exhaust Scavenging: Increased exhaust cam duration improves exhaust gas evacuation from the cylinder, reducing residual exhaust gas and improving volumetric efficiency
• Optimized for NA Performance: Stage 3 specification is tuned for naturally aspirated 2JZ-GE applications where maximizing volumetric efficiency and high-RPM breathing is the primary objective
• Brian Crower Precision: Precision-ground camshaft profiles ensure consistent valve timing and lift across all cylinders for balanced, reliable power delivery

Specifications:

• Brand: Brian Crower
• Part Number: BC0312
• Stage: Stage 3
• Duration: 272°
• Application: Toyota 2JZ-GE (naturally aspirated)
• Sold As: Set (intake and exhaust camshafts)
• Lift: Refer to Brian Crower’s specification sheet for exact lift figures

Fitment Information:

• Lexus IS300 (JCE10) — 2JZ-GE engine
• Lexus GS300 (JZS160) — 2JZ-GE engine
• Other 2JZ-GE applications — verify compatibility with your specific build
• Note: These camshafts are for the naturally aspirated 2JZ-GE only — not for the turbocharged 2JZ-GTE. Verify your engine variant before ordering.
• Installation: Professional installation by an experienced engine builder strongly recommended
• Supporting Modifications: Upgraded valve springs are strongly recommended with Stage 3 camshafts to prevent valve float at high RPM — verify spring compatibility with Brian Crower or your engine builder
• Tune: ECU tune required after installation to optimize for the new camshaft profiles

What’s Included:

• Brian Crower Stage 3 272° camshafts — intake and exhaust set (BC0312)
• Brian Crower specification sheet

Installation Notes:

• Professional installation by an experienced engine builder strongly recommended — camshaft installation requires precise timing and torque procedures
• Upgraded valve springs are strongly recommended with Stage 3 camshafts — factory springs may not provide adequate seat pressure and open pressure for the increased lift and duration
• Verify camshaft bearing clearances before installation
• Set valve timing precisely according to Brian Crower’s specifications — incorrect timing will result in reduced performance or engine damage
• ECU tune required after installation — factory maps will not be optimized for the new camshaft profiles
• Inspect all valve train components (lifters, shims, retainers) and replace as necessary during installation

Understanding Camshaft Duration:

Camshaft duration is the number of degrees of crankshaft rotation during which the intake or exhaust valve is held open. Factory camshafts use relatively conservative duration specifications optimized for idle quality, low-RPM torque, fuel economy, and emissions compliance. Performance camshafts like Brian Crower’s Stage 3 272° grind use longer duration to keep the valves open for more of the engine’s cycle — allowing more air and fuel to enter the cylinder on the intake stroke and more exhaust gas to exit on the exhaust stroke. The trade-off is that longer duration camshafts typically reduce low-RPM torque and idle quality while significantly improving mid-to-high RPM power output. The 272° Stage 3 specification represents a significant step up from factory duration, making it appropriate for dedicated performance builds rather than mild street use.

The 2JZ-GE Platform:

The Toyota 2JZ-GE is the naturally aspirated variant of Toyota’s legendary 2JZ inline-six — a 3.0-litre DOHC engine that shares its robust iron block and forged internals with the turbocharged 2JZ-GTE. While the 2JZ-GTE receives most of the attention in the performance community, the 2JZ-GE’s strong bottom end, smooth power delivery, and high-revving potential make it an excellent platform for naturally aspirated performance builds. With the right camshafts, valve springs, intake, exhaust, and tune, the 2JZ-GE can be transformed into a high-revving, naturally aspirated powerplant that rewards drivers who use the full rev range.

Why Brian Crower?

Brian Crower has been manufacturing high-performance engine components — camshafts, connecting rods, valves, valve springs, and pistons — for professional racing and performance applications since 1986. Their camshaft lineup covers hundreds of applications with application-specific grinds developed through real-world racing and dyno testing. Brian Crower’s 2JZ camshaft lineup is one of the most respected in the Toyota performance community, trusted by professional engine builders and serious enthusiasts worldwide.

Perfect For:

• Lexus IS300 and GS300 owners building a high-performance naturally aspirated 2JZ-GE engine
• 2JZ-GE builds seeking extended high-RPM power and a broader power band
• Engine rebuilds where factory camshafts are being replaced with a performance upgrade as part of a complete head build
• Naturally aspirated 2JZ-GE time attack and track builds maximizing volumetric efficiency and high-RPM output
• Anyone building a serious NA 2JZ-GE who wants Brian Crower’s proven camshaft engineering

Pro Tip: Pair with Brian Crower valve springs and retainers to ensure the valve train can handle the Stage 3 cam’s increased lift and duration at high RPM. A camshaft upgrade without matching valve springs risks valve float — which causes power loss and can result in catastrophic valve-to-piston contact.

Note: 2JZ-GE (naturally aspirated) fitment only — not for the 2JZ-GTE (turbocharged). ECU tune required after installation. Verify valve spring compatibility before ordering.
