HKS 22002-AN023 SS-Cam Step 1 256 Intake Cam for 1993-2002 Nissan Silvia S14/S15

Vehicle Fitment

• 1993-1998 Nissan Silvia (S14, 2.0L SR20DET, RWD) - with NVCS
• 1999-2002 Nissan Silvia (S15, 2.0L SR20DET, RWD) - with NVCS

Fitment Notes

• Designed specifically for SR20DET engines equipped with NVCS (Nissan Variable Cam System) on S14 and S15 platforms
• For S13 / PS13 SR20DET applications, use HKS 22002-AN025 (intake) instead
• Step 1 is compatible with stock valve springs and unmodified cylinder heads - no head work required
• Replaces discontinued legacy Step 1 NVCS part numbers: 22002-AN002, 22002-AN003, and 22002-AN005
• ECU/computer reset recommended after installation for optimal performance results
• Not California emissions legal (not CARB-approved)

Product Description

The HKS 22002-AN023 SS-Cam Step 1 is an entry-level performance intake camshaft engineered specifically for NVCS-equipped SR20DET engines in the Nissan S14 and S15 Silvia. With a 256° duration and 11.5mm lift profile, it delivers a meaningful improvement in mid-range power and throttle response while remaining fully compatible with stock valve springs and an unmodified cylinder head - making it the ideal first camshaft upgrade for street-driven builds.

HKS pre-positions the knock pin at the factory-optimized valve timing location, eliminating the need for measurement or adjustment during installation. Machined from high nickel content iron alloy billet rather than reground OEM cores, this camshaft matches or exceeds OEM quality standards while providing the performance gains expected from an HKS SS-Cam. An ECU reset is recommended after installation to fully realize the timing improvements.
