Restore factory high-RPM performance with this precision machined Ford Contour SVT 2.5L Remanufactured Engine. Production machine centers align-hone the aluminum block casting to true crankshaft bearing centerlines across the engine bay envelope. This 2.5L 6-Cylinder 24-Valve DOHC powerplant requires strict manual pre-lubrication of cylinder head camshaft journals prior to initial starter rotation to prevent valvetrain galling.

Die-cast aluminum alloy block casting 152 contains cast iron cylinder liners and a forged steel crankshaft micro-polished to 0.0003in runout. Dual overhead camshaft aluminum cylinder heads feature extrude-honed intake ports and twenty-four valves actuated by mechanical bucket tappets. Lightweight hypereutectic pistons ride on tri-metal rod bearings. The crated assembly registers a net weight of 252 lbs, crated envelope dimensions of 36in length by 36in width by 36in height, with a 5.8 quarts engine oil capacity.

Key Features of Ford SVT 2.5L

Performance enthusiasts buy Ford SVT 2.5L remanufactured engine assemblies to restore peak horsepower output. Technicians install this remanufactured 2.5L long block replacement to eliminate rod knock and oil starvation issues.

- Aluminum block casting 152 receives precision CNC deck milling to secure multi-layer steel head gaskets.
- Forged steel crankshaft journals undergo micro-polishing down to 0.0003in runout to eliminate bearing friction.
- SVT-specification camshaft lobes undergo profile micrometer scanning to verify factory valve lift curves.
- Extrude-honed cylinder head ports receive three-angle valve seat cutting to maintain 0.001in valve runout.
- Tri-metal rod bearings maintain 0.0012in oil clearance to protect crankshaft journals under track loads.
- Diamond plateau cylinder bore honing creates a crosshatch pattern that seats moly rings within 500 miles.
- Threaded brass oil gallery plugs replace press fittings to safeguard oil pressure at 7,000 RPM.

Dyno Load Precision Machining Tolerances

Dynamometer testing confirms 195 HP at 6,625 RPM and 165 ft-lbs shaft torque at 5,625 RPM under steady brake load testing. Machine shop inspectors verify crankshaft journal runout below 0.0003in TIR while rod bearing oil clearance measures 0.0012in. CNC cylinder bore honing holds piston-to-bore clearance at 0.0012in to prevent cold piston slap. Operating engine oil pressure sustains 60 PSI at 3,000 RPM with engine coolant stabilized at 195°F. Individual cylinder compression gauges verify balanced readings between 185 PSI and 190 PSI across all six cylinders.

Vehicle Fitment Drivetrain Guide

This remanufactured engine fits 1997 Ford Contour SVT performance sedans equipped with the 2.5L 2544cc Duratec 25 SVT V6 engine and body style code 152. It pairs with the MTX-75 5-Speed Manual front-wheel-drive transaxle. This long block does not fit standard 170 HP base Contour 2.5L models, automatic transaxle configurations, 3.0L Taurus Duratec engines, or later returnless fuel system 1999 to 2000 Contour SVT sedans.

Installation Protocol Service Requirements

Inspect dual-stage intake manifold runner control linkages and replace worn front subframe motor mounts before bolting the engine to the transaxle. Never install this naturally aspirated high-output engine into custom turbo conversions or unvented track platforms without secondary oil pan baffles. Mechanics must flush oil cooling lines to clear residual metallic debris.

- Pressure-prime internal oil passages with 5W-30 synthetic motor oil before starter rotation to protect camshaft journals.
- Drain break-in motor oil and install a high-micron oil filter at 500 miles.
- Inspect primary timing chain tensioners and check water pump drive belts at 3,000 miles.
