VEGE 331G 2.4L 2389cc Premium Grade Long Block Remanufactured Crate Engine

Description

Eliminate severe cylinder head warpage problems with the VEGE 331G Remanufactured Crate Engine 2.4L 2389cc premium grade long block package. This remanufactured four-cylinder powerplant produces 155 brake horsepower at 5,600 RPM for long-distance transport rigs. Multi-port fuel injection feeds uniform gasoline charges straight into intake runners, maintaining clean combustion efficiency across high-load highway driving conditions.

A rigid cast iron engine block anchors a balanced forged steel crankshaft held by four-bolt ductile iron main bearing caps. Cylinders receive precision diamond plateau honing to 3.50 inches matched to a 3.78-inch stroke length. Hypereutectic aluminum pistons establish a 9.2:1 compression ratio above forged steel connecting rods. A five-quart baffled oil pan suppresses lubricant aeration while dry long block mass registers 348 lbs.

Key Features of VEGE 331G

Fleet supervisors choose to buy VEGE 331G crate engine modules to repower commercial transport vans and light pickups. Specialized machining procedures restore original factory journal clearances and deck surface squareness for dependable commercial vehicle performance.

• Sixteen-valve dual overhead camshaft cylinder heads maximize airflow charge velocity for responsive mid-range acceleration.
• Induction-hardened valve seat inserts resist valve face erosion under prolonged high-temperature hauling tasks.
• Computer-profiled camshaft lobes maintain smooth valve motion without high-RPM valvetrain bounce.
• Multi-layer steel cylinder head gaskets maintain combustion chamber sealing under extreme thermal expansion cycles.
• High-flow internal oil pumps maintain pressurized lubricant delivery to overhead camshaft journal bores.
• Standardized 331G premium long block bolt patterns mate straight with factory vehicle engine brackets.
• Alloy steel timing chains eliminate timing slack to protect precise valve timing synchronization.

Dynamic Dyno Torque Metrics

Operating across a wide 1,600 to 5,800 RPM power band, this 2.4-liter engine produces 155 brake horsepower at 5,600 RPM. Peak torque output reaches 160 lb-ft at 4,400 RPM, providing immediate pulling force for loaded cargo trucks. Dual overhead camshafts specify 208 degrees intake duration at 0.050-inch lift with 0.405 inches of valve lift. Fuel requirements call for 87-octane pump gasoline. Warm idle manifold vacuum holds 18.5 in-Hg alongside 45 to 60 PSI oil pressure.

Chassis Crossmember Drop Clearance

The rear block interface bolts straight to factory light truck manual and automatic transmission bellhousings using alignment dowels. A neutral-balance flexplate unit isolates driveline vibration under torque load. Factory mounting bosses position the block flat between frame rails, providing complete oil pan drop clearance above steering linkages and front suspension crossmembers without chassis alterations.

Break In Maintenance Protocol

Pre-lube all internal oil passages using an external pressurized lubrication canister before first ignition fire. Charge the crankcase with SAE 10W-30 break-in oil containing elevated zinc levels for proper piston ring seating. This remanufactured crate engine is not engineered for aftermarket turbo boost additions, unmetered nitrous systems, or marine propulsion applications.

• Run the motor between 1,800 and 2,200 RPM for 20 minutes to seat rotating group bearings.
• Change the initial break-in oil and spin-on filter element at the first 500 miles.
• Schedule regular oil and filter changes every 3,000 miles or every 6 months of severe service.

Verified Crate Manifest Terms

A comprehensive 24-Month or 50,000-Mile warranty covers all internal remanufactured mechanical components against defect. The secured freight container encloses the complete long block engine unit, sealed oil pan, dual valve covers, front timing cover, internal oil pump, and an official factory dynamometer inspection verification sheet for technician records.
