VEGE DB43 3.8L 231ci Commercial Grade Long Block Remanufactured Crate Engine

Description

Regain dependable commercial passenger delivery capability with the VEGE DB43 Remanufactured Crate Engine commercial long block package. Displacing 3.8L across 231ci in a ninety-degree V6 format, this motor outputs 170 BHP at 4800 RPM and 200 lb-ft torque at 3200 RPM. Engineered for multi-port fuel injection, it repowers delivery vans and utility fleets with durability.

A deep-skirt cast iron V6 engine block houses cylinders bored to 3.80 inches with a 3.40-inch stroke. The rotating kit incorporates an even-fire nodular iron crankshaft, forged connecting rods, and commercial-grade hypereutectic aluminum pistons. Cylinder pressure builds across an 8.5:1 compression ratio. A 4.5-quart steel oil pan maintains continuous oil pickup during steep grade climbs. Total dry weight measures 380 lbs, preserving proper front-to-rear chassis balance.

Key Features of VEGE DB43

Commercial fleet managers buy VEGE DB43 crate engine packages to recondition utility vans and delivery haulers without dealership markup. Each remanufactured long block receives reinforced aluminum intake manifold gaskets, enlarged oil passages, and precision ground crank journals to eliminate oil burning under continuous heavy loads.

• 3.80-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• Overhead valve pushrod architecture promotes maximum volumetric efficiency across mid-range RPM bands.
• 43.4mm intake valves and 38mm exhaust valves maintain high gas velocity through iron heads.
• 52cc combustion chambers eliminate detonation knock when burning standard 87-octane pump fuel.
• Metal-framed lower intake gaskets halt external coolant leaks under sustained load.
• Hydraulic roller lifters inside the VEGE DB43 valvetrain maintain exact valve clearances.
• Even-fire crankshaft journals resist abrasive wear during heavy-duty fleet operations.
• Stamped steel oil pan clears front drive axles and subframe steering crossmembers.

Combustion Dynamics Dyno Output Specs

The power curve delivers robust performance from 1,000 to 5,200 RPM. Peak dynamometer output reaches 170 brake horsepower at 4,800 RPM alongside 200 lb-ft torque at 3,200 RPM. Camshaft duration measures 196 degrees on intake and 202 degrees on exhaust at 0.050-inch lift, alongside 0.410-inch valve lift. The motor runs on standard 87-octane regular pump unleaded gasoline. Intake manifold vacuum pulls 19.5 in-Hg at a smooth 700 RPM idle. Operating oil pressure regulates between 40 and 68 PSI at 2,500 RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to transverse front-wheel-drive automatic transmission casings. An internal neutral balance crank flange connects straight to production torque converter flexplates. Factory cast iron engine mount brackets line up with chassis rubber isolators, preserving three inches of clearance beneath the vehicle hood structure.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil passages with a pressurized tank before initial startup to protect journal bearings. Fill the crankcase with SAE 10W-30 mineral break-in oil and bleed trapped air bubbles from heating circuit hoses. This commercial V6 motor is not engineered for turbocharger boost, competitive drag racing, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to bed in camshaft lobes.
• Drain initial break-in oil and install a fresh oil filter after the first 500 miles.
• Replace crankcase motor oil and inspect all drive belts every 3,000 miles.

Verified Warranty Physical Crate Manifest

A 36-Month / 100,000-Mile nationwide limited warranty provides long-term mechanical protection against defects. The heavy transport crate contains the remanufactured long block, stamped steel oil pan, aluminum timing cover, harmonic damper, stamped valve covers, oil pressure verification report, and an installation instruction handbook.
