The Honda C32A2 is a 3,179 cc, naturally aspirated V6 petrol engine produced between 1991 and 1996. It features a single overhead camshaft (SOHC) per bank with 24 valves and Honda's PGM‑FI fuel injection system. This configuration delivered approximately 152 kW (207 PS) and 284 Nm of torque, providing smooth, refined power for luxury applications.
Fitted primarily to the first-generation Honda Legend (KA chassis) and Acura Legend in North America, the C32A2 was engineered for quiet, effortless performance and high-speed stability. Emissions compliance for its production period was managed through precise fuel metering and a three-way catalytic converter, meeting the applicable standards for European and other international markets at the time.
One documented service consideration involves the cylinder head gaskets, where a design revision was implemented during the 1993 model year to address potential oil seepage. This is detailed in Honda Service Bulletin 94‑022, which outlines the updated gasket part number and installation procedure for affected engines.
Production years 1991–1996 meet the emissions standards applicable for their respective model years and markets (VCA UK Type Approval #VCA/EMS/5680).
The Honda C32A2 is a 3,179 cc 60-degree V6 naturally aspirated petrol engine engineered for flagship sedans (1991-1996). It combines SOHC 24-valve architecture with PGM-FI electronic fuel injection to deliver broad, linear power delivery. Designed to meet the emissions regulations of its production era, it prioritizes refinement, smoothness, and long-term durability.

The SOHC 24-valve design offers a broad, smooth torque curve ideal for relaxed cruising. The timing belt must be replaced at the specified interval (approx. 100,000 km) as this is an interference engine. Using the specified API SG/SH grade oil ensures proper lubrication for the hydraulic lifters and timing belt tensioner. The cylinder head gaskets, subject to a mid-cycle update per SIB 94-022, should be inspected for oil seepage during major services; replacement with the updated part number is recommended if leaks are found.
Oil Specs: Requires API SG/SH specification oil (Honda Owner's Manual 1993). Modern equivalents (e.g., API SN) are generally acceptable if viscosity (10W-30) is maintained.
Emissions: Certification applies to 1991-1996 models for their respective markets (VCA Type Approval #VCA/EMS/5680). Specific standards vary by region.
Power Ratings: Measured under SAE J1349 standards (Honda Group PT-1994). Output figures are for stock, unmodified engines.

The Honda C32A2 was used exclusively in Honda's KA platform with longitudinal mounting. This engine received a minor mid-cycle update to the cylinder head gasket design in 1993, creating a distinction between early and late production units. All adaptations are documented in OEM technical bulletins.
The engine code "C32A2" is stamped on a flat pad on the front face of the engine block, near the oil filter (Honda TIS H87658). The 8th digit of the VIN for vehicles equipped with this engine is typically "C". Visually, it can be identified by its wide, low-profile V6 configuration with a single serpentine belt driving all accessories and a black plastic intake manifold spanning both cylinder banks. Critical differentiation from the similar C32A1: The C32A2 features a slightly higher compression ratio (9.6:1 vs 9.4:1) and was used in later model years; the engines are otherwise mechanically very similar.
The C32A2's primary reliability consideration is adherence to the timing belt replacement schedule, with elevated risk of engine damage if neglected. Honda service data indicates that engines with missed belt changes are prone to catastrophic failure, while general mechanical robustness is well-documented. The updated cylinder head gasket (post-1993) resolved most seepage issues, making regular oil checks and timely belt changes critical for long-term health.
