VEGE DFEN 3.9L 238ci Multi Purpose Long Block Remanufactured Crate Engine

Description

Restore factory passenger vehicle acceleration using the VEGE DFEN Remanufactured Crate Engine 3.9L 238ci long block package. Delivering 193 horsepower at 4,500 RPM and 225 lb-ft torque at 2,800 RPM, this balanced pushrod V6 rebuilds dependable performance. Re-machined cylinder head decks and upgraded intake manifold gaskets eliminate coolant mixing, restoring original operating temperatures across passenger cars and minivans.

Cast iron 90-degree block architecture employs cross-bolted main caps clamping a balanced nodular iron crankshaft. Forged powdered metal connecting rods carry hypereutectic pistons cycling within a 3.810-inch bore and 3.500-inch stroke. Compression holds at 9.3:1 for regular fuel use. The stamped steel front-sump oil pan holds 5.0 quarts, bringing dry engine weight to 405 lbs.

Key Features of VEGE DFEN

Smart vehicle owners buy VEGE DFEN crate engine assemblies to replace worn powertrains in late-model Mustangs and minivans. Precision remanufacturing reestablishes tight mechanical tolerances, restoring smooth engine idling and crisp throttle response right from initial startup.

• Split-port induction architecture improves combustion chamber turbulence for cleaner tailpipe emissions.
• 47 mm intake valves maximize airflow volume during highway passing maneuvers.
• DFEN multi purpose units feature upgraded intake gasket landing surfaces to halt internal fluid leaks.
• Dynamic balancing eliminates intrusive secondary vibrations to ensure quiet passenger cabin travel.
• Plateau-honed cylinder walls establish immediate piston ring bedding without premature cylinder wall scuffing.
• Hydraulic roller lifters track polished camshaft lobes to minimize valvetrain friction and wear.
• Brand new timing chain sets maintain exact camshaft timing through thousands of stop-and-go trips.

Combustion Chamber Dyno Characteristics

Operating across an engine band from 1,200 to 5,200 RPM, this V6 outputs 193 peak brake horsepower at 4,500 RPM and 225 lb-ft torque at 2,800 RPM. Camshaft duration checks in at 186 degrees intake at 0.050-inch lift, with 0.440-inch valve lift. Designed to run on 87-octane regular pump gasoline. Warm idle vacuum pulls 19 in-Hg at 650 RPM, backed by 40 to 60 PSI oil pressure hot.

Chassis Clearance Transaxle Integration

The rear block interface bolts directly to Ford 4R70W automatic and T5 manual transmissions without adapter plates. External balance demands matching weighted flexplates or flywheels. Sump contours drop cleanly around steering racks and suspension crossmembers, providing ample clearance for steering intermediate shafts, starter wiring, and exhaust collectors.

Maintenance Protocols Operating Boundaries

Pre-lube all internal oil passages using an external pressure reservoir before starting the engine. Charge the crankcase with 5W-20 synthetic blend oil and bleed all cooling passages thoroughly. This engine unit is not engineered for centrifugal blowers, turbochargers producing over 5 PSI, or drag racing launches.

• Discard break-in motor oil and install a replacement oil filter after the first 50 miles.
• Renew engine oil and inspect accessory drive belts every 3,000 miles of service.
• Inspect cooling lines and coolant freeze protection every 12 months for thermal protection.

Factory Warranty Crate Contents

Covered by a 36-Month / 100,000-Mile nationwide limited warranty against defects in parts and workmanship. The crated unit contains the remanufactured long block, complete oil pan, front timing cover, reconditioned heads, balance verification card, and a technical startup guide.
