On Honda engines, the engine code takes priority over engine capacity: a 1.5-litre can hide three incompatible parts

This is the most common pitfall with Honda: the engine capacity shown is not enough to identify the correct part. The 1.5-litre petrol block is the clearest example — it covers at least three distinct engine codes. The L15B7 fits the 1.5 Turbo, the 1.5 VTEC Turbo and the 1.5 T Si alike, while the 1.5 T comes in L15BM and L15BN variants depending on the version. The same logic applies to the 1.3: four codes coexist (L13A1, L13B1, L13B2, L13Z1), corresponding to different generations and applications across the Jazz and Civic. Before placing any order, the code stamped on the engine is the only reliable reference.

Turbos and gearboxes: two families, each with clearly defined scope

The Honda range focuses on two part families. Turbos make up the largest share, covering both diesel blocks — 1.6 i-DTEC (N16A1 / N16A2) and 2.2 i-CTDi (N22A2) — and turbocharged petrol blocks, notably the 1.0 VTEC (P10A2) and the various versions of the 1.5 T. The gearboxes available are 5- or 6-speed manuals, principally for the Civic and CR-V. No automatic gearbox or dual-clutch unit features within this scope.

Civic leads the way, but CR-V, Accord and Jazz are covered too

The Civic accounts for the majority of available references, reflecting the breadth of its engine range across recent generations. The CR-V is covered on the diesel i-DTEC and i-CTDi versions. The Accord and Jazz round out the catalogue on specific engine variants. Parts are offered either on an exchange basis or as a rebuild of the original unit, depending on the family in question — two distinct sales methods that do not apply to the same references. For new turbos, a third option exists on certain references. Check your vehicle's engine code before selecting a reference: it is the only piece of information that removes any ambiguity between apparently identical engines.
