High-RPM connecting rod bolt stretch and sintered oil pump gear fracture destroy hand-built race engines under track competition. The Acura Integra Type R B18C5 1.8L L4 Remanufactured Engine eliminates rotating assembly separation across this commercial long block repower. This 4-Cylinder 195HP DOHC VTEC powerplant requires oil pump pickup tube clearance verification before securing the baffled oil pan.

High-density A356-T6 aluminum forms the open-deck block casting showing P73 left bellhousing and B18C5 right-side casting stamps. Centrifugal iron sleeves house high-compression domed pistons joined to a balanced 4140 forged steel crankshaft spinning in tri-metal bearings. This Acura engine core demands a 12V 140A starter draw during cold morning cranks. Dry weight measures 185 lbs inside a 23in length, 22in width, 25in height stance holding 4.3 quarts of oil.

Key Features of Acura Integra Type R B18C5

Race team directors buy Acura Integra Type R B18C5 1.8L L4 Remanufactured Engine units to secure reliable championship finishes. Our industrial engine rebuild standard incorporates hand-finished intake ports and dual-valve spring sets to stop valvetrain float past 8000 RPM.

- Cylinder bores measure 3.189in with diamond plateau hone surface textures.
- Main journal oil clearance holds at 0.0015in across the five-bearing main girdle.
- High-angle VTEC camshaft lobes deliver rapid valve opening duration under wide open throttle.
- Factory-spec oil squirter jets drop piston crown temps under continuous full-load pulls.
- Multi layer steel head gaskets stop combustion blowby across high-compression cylinder decks.
- This B18C5 commercial core features cylinder head decks surfaced flat to 0.0003in.
- Stellite exhaust valve faces resist thermal seat recession during high-temperature track sessions.

Brake Cell Load Verification

Automated brake cell runs verify that this B18C5 long block engine generates 195 continuous BHP and 130 ft-lbs of torque at 7300 continuous load RPM. Internal oil gallery pressure measures 58 PSI with oil sump temp steady at 194°F under full brake load. Exhaust gas temp tops at 1340°F down the tuned header collector. Cylinder compression checks between 185 PSI and 192 PSI across all four chambers. Crankshaft center journal runout holds within 0.0002in TIR.

Chassis Fitment Platform Scope

This competition powerplant matches 1997 through 2000 Acura Integra Type R three-door hatchbacks on DC2 chassis platforms. Installation drops onto factory front-wheel-drive engine mount points paired with S80 five-speed manual transaxles utilizing OEM helical limited-slip differentials and 1834 body style harness connections.

Field Installation Operational Boundaries

Throttle quadrant cable mechanisms need 4 lbs of spring resistance to guarantee positive throttle body plate closing at idle. This high-strung naturally aspirated engine is not engineered for automatic transmissions, turbocharger drag builds, marine stern drives, or stationary generator pump skids.

- Drain initial break-in petroleum motor oil after 500 miles or 25 operating hours.
- Inspect cold intake valve clearance at 0.006in and exhaust clearance at 0.007in.
- Torque cylinder head fasteners in two stages to 63 ft-lbs final specification.
