Nissan 300ZX Pickup VG30E 3.0L V6 Engine 1983-1987

Description

Restore rear-wheel-drive sports performance and truck torque with this Nissan 300ZX VG30E Remanufactured Engine. Each 3.0L 6-Cylinder 12-Valve SOHC long block features diamond-resurfaced deck surfaces and renewed timing components. Technicians must prime internal oil passages prior to ignition and execute an exact 500-mile break-in oil change to protect the single overhead camshaft lobes from premature contact wear.

Built with cast iron block casting V52, this engine block features 4-boss motor mount provisions and rigid cylinder wall stability. The rotating assembly features a short-snout micro-polished forged steel crankshaft, forged connecting rods, and oversized hypereutectic pistons with anti-scuff skirts. Cylinder head casting V52 receives diamond milling for head gasket retention. Dry long block weight totals 240 lbs inside crated dimensions of 36in length by 36in width by 36in height. Engine oil capacity equals 4.5 quarts.

Key Features of Nissan VG30E

Independent automotive repair technicians buy Nissan VG30E remanufactured engine long blocks to resolve chronic head gasket failure and valvetrain noise. This long block replacement provides verified machine shop tolerances for sports car and light truck platforms.

• Block casting V52 features 4-boss motor mount patterns for universal passenger car and truck chassis fitment.
• Pre-installed timing belt and mechanical tensioner eliminate cam timing setup errors during garage installation.
• Short-snout micro-polished crankshaft journals eliminate runout to protect bi-metal bearings under load.
• Diamond plateau honed cylinder walls establish an Ra 15 micro-inch crosshatch finish for ring seating.
• Align-honed cast iron main bearing saddles maintain roundness to prevent crankshaft binding under torque.
• Multi-layer composite cylinder head gaskets withstand severe thermal expansion across 2 aluminum heads.
• New high-grade cylinder head bolts supply uniform clamp loads across all 6 combustion chambers.

Dyno Bench Clearance Machining Specifications

Dyno cell spin testing verifies mechanical oil gallery pressurization and rotating balance before crate shipment. The 3.0L 2960cc SOHC V6 outputs 160 HP at 5,200 RPM and 173 ft-lbs of shaft torque at 3,600 RPM. Crankshaft main journal oil clearance measures 0.0011in to 0.0015in, while connecting rod clearance holds at 0.0012in. Individual cylinder compression gauges verify 180 PSI across all 6 cylinders. Hot engine oil pressure maintains 55 PSI at 3,000 RPM with regulated coolant operating temperatures steady at 190°F.

Vehicle Fitment Drivetrain Guide

This engine fits 1984 to 1987 Nissan 300ZX, 1985 to 1987 Nissan Maxima, 1986 to 1987 Nissan D21 Hardbody, and 1987 Nissan 200SX models equipped with the 3.0L 2960cc VG30E engine, block casting V52, short crank snout, and 4-boss motor mounts. Compatible drivetrains include rear-wheel drive and front-wheel drive paired with manual or automatic transmissions. This long block does not fit 2-boss mount 300ZX chassis or later long-snout VG30E platforms due to crank pulley differences.

Installation Protocol Service Requirements

Technicians must verify crank pulley snout depth, inspect motor mount boss alignment, and purge air from heater core circuits during installation. Operational warnings restrict use in custom turbo applications exceeding 6 PSI boost on stock compression pistons or off-road mud runners lacking auxiliary oil filtration.

• Pre-fill the spin-on oil filter and prime lubrication passages with 10W-30 conventional oil before cranking.
• Drain initial break-in oil and install a replacement oil filter at the 500-mile maintenance mark.
• Check mechanical rocker arm clearance and verify distributor timing advance with a timing light at 1,500 miles.
