Boundary VG30E-S2-M Nissan VG30E Stage 2 MartenWear Oil Pump Assembly

The Boundary VG30E-S2-M is a Stage 2 billet oil pump assembly engineered for the Nissan VG30E V6 engine. Built on the OEM housing and fitted with Boundary's industry-leading mirror-finished billet gear set, this assembly is treated with Boundary's proprietary MartenWear Dual Heat Treat process — a surface hardening treatment validated on the bench to 12,000 RPM without measurable wear, ensuring sustained oil pressure even under extreme high-RPM and high-performance conditions.

Every Boundary assembled pump undergoes a rigorous multi-step quality process before it leaves the facility:

• Complete disassembly followed by ultrasonic cleaning, air blast, and hand inspection
• Hand de-burring to eliminate imperfections and reduce flow turbulence
• Mirror-finished billet gear set installed for maximum efficiency and longevity
• MartenWear Dual Heat Treat applied to gear teeth for hardness and wear resistance at high RPM
• Stainless Torx head fasteners replace OEM hardware
• All fasteners torqued to spec with Loctite applied to prevent loosening or back-out
• Anaerobic sealant applied to critical sealing areas to accelerate pump prime and reduce aeration
• Assembly lubricant applied to all critical surfaces for immediate oil flow on startup
• Blueprinted and shipped with a signed specification sheet documenting individual pump clearances

The Boundary VG30E-S2-M is a direct bolt-on upgrade over the OEM oil pump, delivering improved reliability and high-RPM oil pressure stability for street, track, and performance builds. Backed by Boundary's lifetime warranty and manufactured in the USA.
