Intake manifold air assist port clogging and cylinder head combustion deck cracking cause rough idle across late-model commuter cars. The Acura Honda D16Y8 1.6L L4 Remanufactured Engine 1999-2000 rectifies intake runner imbalance throughout this commercial long block repower. This 4-Cylinder 127HP SOHC build requires knock sensor thread torque verification before intake manifold installation.

Cast A356-T6 aluminum forms the lightweight open-deck block casting with P2E bellhousing driver-side identification stamps. Centrifugal spun cast iron liners house cast aluminum pistons linked to a balanced forged steel crankshaft. This Acura Honda engine core requires a 12V 135A starter draw under cold crank testing. The crated unit weighs 190 lbs dry, spanning a 22in length, 21in width, 24in height envelope holding 3.8 quarts of oil.

Brake Dyno Performance Records

Controlled brake cell testing confirms that this D16Y8 long block engine produces 127 continuous BHP and 107 ft-lbs of torque at 5500 continuous load RPM. Internal oil gallery pressure measures 52 PSI with oil sump temp steady at 191°F under full thermal loading. Exhaust gas temp remains under 1250°F down the test header pipe. Cylinder compression measures between 180 PSI and 188 PSI across all four bores. Crankshaft snout runout checks out at 0.0002in TIR.

Field Installation Operational Limits

Throttle quadrant cable connections demand 4 lbs of linear pull force to maintain smooth throttle body blade movement without hesitation. This transverse engine is not designed for methanol competition racers, outboard boat conversions, or hydraulic pump station equipment.

- Evacuate initial break-in petroleum motor oil after 500 miles or 30 run hours.
- Check cold intake valve lash at 0.008in and exhaust lash at 0.010in.
- Torque cylinder head fasteners in sequence to 49 ft-lbs final torque.

Factory Warranty Delivery Manifest

Every engine produced to the Acura Honda assembly standard carries a 3-Year 100,000-mile parts protection warranty. Each palletized crate contains the remanufactured long block, water pump, timing belt, timing gears, tensioner, oil pan, valve cover, oil pickup tube, and signed dyno load sheet.
