VEGE Remanufactured DP51 2.5L 151ci Compact Car Long Block Engine

Description

Stripped composite camshaft gears and cracked exhaust manifolds leave postal delivery runabouts stranded on suburban routes. The VEGE Remanufactured DP51 Compact Car Long Block Engine terminates valvetrain timing failure during an industrial engine rebuild. This 2.5L 151ci 4-Cylinder Iron Duke powerplant produces 90HP. Technicians must inspect distributor drive tang engagement depth prior to clamp torquing.

Heavy wall ASTM A48 Class 30 gray iron composes the sturdy engine case and overhead valve cylinder head. A precision balanced nodular iron crankshaft turns inside tri-metal bearings inside this VEGE engine build. Cold cranking draws 130A through standard 12V automotive battery circuits. Total dry unrigged mass registers 300 lbs across dimensions of 22in length, 21in width, 24in height. The stamped steel sump holds 4.0 quarts.

Key Features of VEGE Remanufactured DP51

Postal fleet supervisors buy VEGE Remanufactured DP51 Compact Car Long Block Engine units to keep courier vehicles on the road. Every commercial long block repower integrates upgraded all-metal timing gears and resurfaced iron heads to prevent catastrophic timing gear strip failures.

• All metal camshaft gears replace fragile composite fiber gears to eliminate catastrophic tooth shearing.
• Hydraulic flat tappet camshafts deliver predictable valve lift profiles tuned for city delivery routes.
• 0.0012in rod journal clearances preserve protective hydrodynamic oil films under high temperature stop-and-go idling.
• The DP51 commercial core features induction hardened exhaust valve seats for unleaded fuel durability.
• Plateau honed cylinder walls allow cast iron compression rings to seat fast without bore scuffing.
• Multi layer steel cylinder head gaskets prevent combustion gas blowby between adjacent cylinder chambers.
• Single piece viton rear crankshaft seals stop oil seepage into the transmission bellhousing.

Dyno Continuous Load Ratings

Shop dynamometer sweeps measure this DP51 long block engine at 90 BHP and 132 ft-lbs of torque at 2800 RPM continuous test loading. Main gallery oil pressures register 45 PSI at 190°F oil pan thermal stabilization. Exhaust runner probes reach 1180°F during sustained continuous test runs on the water brake absorber unit. Dynamic compression testing displays 170 PSI across all four cylinders within 3% balance across the block. Crankshaft center journal runout measures under 0.0002in TIR to avoid bearing babbit wear under load.

Vehicle Installation Usability Guidelines

Carburetor or throttle body linkages require 3 lbs of return spring pull to ensure complete throttle closure at idle. This 2.5L four cylinder pushrod engine is NOT engineered for turbocharged track racing platforms, marine inboard pleasure craft, or heavy commercial dump trucks.

• Drain break-in motor lubricant and replace the spin-on filter element at 500 miles or 30 operating hours.
• Set hydraulic flat tappet rocker arm nuts to zero lash plus one-half turn down during cold bench setup.
• Torque cylinder head fasteners in proper progression sequence using specified angle rotation gauges without hot retorque passes.

Crated Warranty Protection Scope

Remanufactured in compliance with the VEGE assembly standard, this compact long block carries a 3-Year 100,000-mile parts warranty. The timber freight box holds the assembled long block, stamped steel oil pan, front timing cover, stamped valve cover, pickup tube screen, and signed dynamometer quality checklist.
