VEGE 712A 2.5L 2458cc Multi Purpose Long Block Remanufactured Crate Engine

Description

Eliminate persistent head gasket leaks with the VEGE 712A Remanufactured Crate Engine multi-purpose long block package. This 2.5L 2458cc DOHC boxer four-cylinder motor generates 165 BHP at 5600 RPM and 162 lb-ft torque at 4000 RPM. Designed for multi-port fuel injection, it repowers passenger sedans and wagons while restoring crisp acceleration and original factory mechanical reliability.

The split-case aluminum alloy engine block houses centrifugally cast iron cylinder liners honed to a 3.92-inch bore and 3.11-inch stroke. The reciprocating group contains a heat-treated forged steel crankshaft, forged connecting rods, and premium hypereutectic aluminum pistons. Cylinder pressure achieves a 9.7:1 compression ratio for regular fuel operation. A 4.5-quart steel wet sump oil pan manages oil circulation. Dry engine mass checks in at 285 lbs, preserving vehicle steering precision.

Key Features of VEGE 712A

Independent repair professionals buy VEGE 712A crate engine packages to cure chronic coolant weeping and rod knock in all-wheel-drive passenger vehicles. Each remanufactured unit receives precision deck surfacing and line-bored main bearing tunnels to guarantee dependable gasket retention.

• 3.92-inch cylinder bores feature diamond plateau honing to seat piston rings fast.
• Dual overhead camshaft configuration provides four valves per cylinder for superior high-RPM breathing.
• 36mm intake valves and 32mm sodium-cooled exhaust valves enhance thermal dissipation in aluminum heads.
• 47cc combustion chambers resist detonation knock when burning standard 87-octane pump gasoline.
• Multi-layer steel head gaskets halt external fluid leaks across extreme thermal cycles.
• Solid bucket valvetrain adjusters inside the VEGE 712A cylinder heads maintain exact valve lash.
• Forged steel crankshaft runs on micro-polished tri-metal main and rod bearings.
• Stamped steel oil pan clears front subframe members and steering rack boots.

Combustion Dynamics Dyno Output Specs

This DOHC boxer operates smoothly between 1,200 and 6,200 RPM. Peak dynamometer figures reach 165 brake horsepower at 5,600 RPM alongside 162 lb-ft torque at 4,000 RPM. Camshaft duration measures 212 degrees on intake and 208 degrees on exhaust at 0.050-inch lift, paired with 0.355-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. Hot oil pressure maintains between 45 and 68 PSI at 3,000 RPM.

Drivetrain Interface Engine Bay Clearance

The rear bellhousing pattern aligns flush to longitudinal all-wheel-drive manual transaxles and automatic transmission cases. An internal neutral balance crank hub attaches straight to production flywheels or torque converter flexplates. Side motor mount brackets align with original rubber chassis pads, leaving three inches of clearance behind the radiator core support.

Break-In Protocol Maintenance Parameters

Pre-lube all engine oil galleries using a pressurized tank prior to the first crank cycle. Fill the sump with high-zinc SAE 10W-30 mineral break-in oil and bleed trapped air from cooling circuits. This atmospheric DOHC boxer is not engineered for turbocharger boost, competitive track lapping, or unmetered nitrous oxide injection.

• Run motor at 2,000 RPM for 20 minutes to mate camshaft lobes to buckets.
• Drain initial break-in lubricant and install a fresh oil filter after the first 500 miles.
• Change synthetic crankcase oil and inspect rubber coolant hoses every 3,000 miles.

Verified Warranty Physical Crate Manifest
