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 enginee…
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 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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the C32A2 is a very robust and reliable engine when properly maintained. Its simple, non-turbocharged design and high-quality construction mean it can easily surpass 300,000 km. The single most critical maintenance item is the 100,000 km timing belt replacement, as failure will destroy the engine. With this attended to, along with regular oil changes, the C32A2 is known for exceptional longevity.
The most critical issue is timing belt failure, which causes catastrophic engine damage. Other common problems include minor oil seepage from early-design cylinder head gaskets (resolved in 1993), failure of the main relay causing no-start conditions, and valve cover gasket leaks. These are all well-documented and relatively inexpensive to address.
The C32A2 was used exclusively in the first-generation Honda Legend (KA7/KA8 chassis) from 1991 to 1996. It was also fitted to the equivalent Acura Legend models sold in North America during the same period. It is the higher-compression variant of the initial C32A engine family.
Modest power gains are possible. Common upgrades include a performance exhaust system, high-flow air filter, and ECU chip tuning to optimize the PGM-FI system. Significant power increases are limited by the SOHC head design. Focus is usually on improving throttle response and mid-range torque rather than peak horsepower, as the engine is already tuned for smooth, linear power delivery.
Fuel economy is moderate for a 3.2L V6 of its era. In a typical Legend sedan, expect combined figures around 10.5-11.5 L/100km (27-25 mpg UK). Highway cruising can yield 8.5-9.0 L/100km (33-31 mpg UK), while city driving may be 13.0-14.0 L/100km (22-20 mpg UK). Actual figures depend heavily on driving style and vehicle condition.
Yes. The Honda C32A2 is an interference engine. This means that if the timing belt breaks or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes the 100,000 km timing belt replacement interval absolutely critical.
Honda originally specified API SG or SH grade oil, typically in a 10W-30 viscosity for normal operating conditions. Modern, high-quality synthetic or semi-synthetic oils meeting API SN or higher standards in 10W-30 (or 5W-30 for colder climates) are perfectly suitable and often provide better protection, especially for older engines.
