VEGE Remanufactured DFZV 2.5L 152ci Compact Car Long Block Engine

Description

Non-keyed crankshaft timing sprocket slippage and spark plug tube seal weepage terminate upon sourcing the VEGE Remanufactured DFZV 2.5L Long Block Engine. Generating 175HP from a 152ci 4-Cylinder commercial long block repower format, this unit powers urban courier cars. Installers must position diamond-faced friction washers between the crankshaft timing sprocket and harmonic damper face prior to torquing center bolts.

Engineers specify ASTM A356-T6 cast aluminum for the engine block casting, using centrifugally cast iron liners for superior bore durability. The VEGE engine core pairs low-friction moly-coated piston skirts with case-hardened wrist pins. Cranking draws 12V 145A through starter contacts. Dry unrigged mass measures 260 lbs inside a 21in length, 20in width, 24in height base envelope with 4.5 quarts oil volume.

Key Features of VEGE DFZV

Delivery company operators buy VEGE DFZV commercial long block packages to stop roadside engine dropouts. Our clean-room assembly team follows certified industrial engine rebuild quality tolerances on every production engine.

• Forged carbon steel camshaft profiles provide accurate valve timing duration across heavy stop-start urban cycles.
• Spheroidal graphite iron crankshaft shows zero runout variance past a strict 0.0002in TIR threshold.
• Multi-layer steel head gasket construction prevents oil-to-coolant migration across aluminum deck mating points.
• Sintered powdered metal valve seat rings provide high thermal dissipation under elevated urban operating conditions.
• Precision-bored cylinder sleeves maintain 0.0002in out-of-round roundness limits across full piston travel stroke.
• DFZV commercial core design uses deep oil drainback passages to eliminate cylinder head pool accumulation.
• Bi-metal aluminum-tin crankshaft bearings provide 0.0012in clearance to prevent thermal surface scuffing.

Dynamic Bench Load Operating Thresholds

Automated test dynos confirm 175 continuous BHP and 170 ft-lbs torque output at 4500 RPM continuous sweep calibration. Monitoring displays 48 PSI galley pressure at 190°F oil sump temperature, while exhaust gas temp peaks at 1210°F under maximum test pull. Cylinder compression measures 185 PSI across all four cylinders within 3% balance. Crankshaft runout checks at 0.0002in TIR on the DFZV long block engine.

Installation Requirements Negative Filter Rules

Throttle spool return resistance measures 4 lbs force on the bracket return spring. This power plant is NOT engineered for turbo installations without forged piston pin upgrades or extreme motorsport competition. Installation technicians must execute verified startup maintenance protocols without exception.

• Drain break-in crankcase oil supply and replace filter element at 500 miles.
• Verify solid bucket tappet cold lash at 0.009in intake and 0.013in exhaust before road tests.
• Check all lower timing cover perimeter bolts for correct sealing torque after the first thermal cycle.

Warranty Statement Wood Crate Inventory

All rebuilding procedures meet strict VEGE assembly standard metrics covered by a 3-Year 100,000-mile warranty. The wood transport container houses the long block core, stamped oil pan, aluminum front cover, stamped valve cover, oil pickup tube, and signed dyno run verification sheet.
