Brian Crower Stage 3 Intake Camshaft – Toyota / Lexus 2JZ-GE | IS300 / GS300 | Naturally Aspirated | Intake Only | High-RPM Performance

The Brian Crower Stage 3 Intake Camshaft for the Toyota/Lexus 2JZ-GE (BRCBC0312-INT) is a performance intake camshaft engineered for the naturally aspirated 2JZ-GE inline-six — delivering an aggressive Stage 3 cam profile with increased lift and duration over the factory camshaft for improved high-RPM power output and a broader, more aggressive power band. Sold as an intake camshaft only — pairs with the factory 2JZ-GE exhaust camshaft or a matching Brian Crower exhaust camshaft for a complete camshaft upgrade. The 2JZ-GE is the naturally aspirated variant of Toyota's legendary 2JZ inline-six — used in the Toyota Altezza/Lexus IS300 and Lexus GS300 — a DOHC, 24-valve engine with a strong performance aftermarket and significant power potential through camshaft, head, and intake upgrades. Brian Crower is the most respected performance camshaft manufacturer for Japanese performance engines in the North American market — a brand trusted by professional engine builders and top-level competition teams worldwide.

Key Features:

• Stage 3 profile — Brian Crower's Stage 3 camshaft specification — an aggressive performance cam profile with significantly increased lift and duration over the factory 2JZ-GE intake camshaft — engineered for high-RPM power output and a broader, more aggressive power band
• Increased lift — greater valve lift than the factory camshaft — allows more air/fuel mixture to enter the combustion chamber at each intake event — improving volumetric efficiency and power output, particularly at high RPM
• Increased duration — longer intake valve opening duration than the factory camshaft — keeps the intake valve open longer to take advantage of intake charge momentum at high RPM — improving high-RPM power delivery
• Intake only — intake camshaft only — pairs with the factory 2JZ-GE exhaust camshaft for a single-cam upgrade, or with a matching Brian Crower Stage 3 exhaust camshaft for a complete dual-cam upgrade
• 2JZ-GE specific — engineered specifically for the naturally aspirated 2JZ-GE — correct lobe profile, base circle diameter, and journal dimensions for the 2JZ-GE's DOHC cylinder head
• Brian Crower quality — manufactured by Brian Crower, the most respected performance camshaft manufacturer for Japanese performance engines in the North American market

Stage 3 — Cam Profile Context:

Brian Crower's camshaft lineup for the 2JZ-GE is organized by stage — each stage representing a progressively more aggressive cam profile with increased lift and duration:

• Stage 1 / Stage 2: Mild to moderate performance profiles — improved power with minimal impact on idle quality and low-RPM drivability — correct for street-driven builds
• Stage 3 (this camshaft): Aggressive performance profile — significant lift and duration increase for high-RPM power — may affect idle quality and low-RPM drivability — correct for performance-focused street and track builds where high-RPM power is the priority

The Stage 3 profile is the correct choice for 2JZ-GE builds targeting maximum naturally aspirated power output — typically paired with head porting, upgraded valve springs and retainers, a high-flow intake manifold, and a performance exhaust system to fully realize the camshaft's power potential.

2JZ-GE — Platform Context:

The Toyota 2JZ-GE is the naturally aspirated variant of Toyota's legendary 2JZ inline-six — a 3.0L DOHC 24-valve engine used in the Toyota Altezza RS200 (JDM), Lexus IS300 (2001–2005), and Lexus GS300 (1993–2005). While the 2JZ-GTE (turbocharged) receives the majority of performance attention, the 2JZ-GE has a dedicated naturally aspirated performance community — with significant power potential through camshaft upgrades, head work, intake and exhaust modifications, and high-compression builds. The 2JZ-GE's DOHC architecture and strong bottom end make it an excellent platform for naturally aspirated performance development. Brian Crower's Stage 3 intake camshaft is the correct aggressive cam upgrade for 2JZ-GE builds targeting maximum NA power output.

Specifications:

Fitment Information:

• Toyota/Lexus 2JZ-GE — naturally aspirated — DOHC 24-valve
• Lexus IS300 — 2001–2005
• Lexus GS300 — verify specific model years
• Toyota Altezza RS200 — JDM
• Intake camshaft only — pairs with factory exhaust cam or Brian Crower Stage 3 exhaust camshaft
• Note: The Stage 3 profile requires upgraded valve springs and retainers to safely operate at the increased lift — verify that your 2JZ-GE's valve springs are rated for the Stage 3 cam's lift specification before installation. Professional engine builder installation strongly recommended. A cam degree procedure is required after installation to verify correct cam timing.

What's Included:

• Brian Crower Stage 3 intake camshaft — Toyota/Lexus 2JZ-GE (BRCBC0312-INT)
• Refer to Brian Crower's product documentation for complete specifications including lift, duration, and LSA

Installation Notes:

• Professional engine builder installation strongly recommended — camshaft installation on the 2JZ-GE requires correct cam timing verification, correct cam cap torque sequence, and correct valve clearance adjustment after installation
• Upgraded valve springs and retainers are required — the Stage 3 cam's increased lift exceeds the safe operating range of the factory valve springs — install Brian Crower or equivalent upgraded valve springs and retainers rated for the Stage 3 lift specification before or simultaneously with camshaft installation
• Degree the camshaft after installation — verify correct intake cam timing using a degree wheel and dial indicator — correct cam timing is critical for achieving the Stage 3 profile's intended power characteristics
• Verify valve-to-piston clearance after installation — the increased lift of the Stage 3 cam may reduce valve-to-piston clearance on high-compression or stroked 2JZ-GE builds — verify clearance before running the engine
• Check valve clearances after installation and after the first heat cycle — adjust shims as required to achieve correct valve clearance specification
