Why Choose Engine Finders for Your Honda Z Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Honda Z replacement engines. From K20A/B air-cooled twins to L12A/L13A water-cooled fours found across the Z360-Z660 range, we solve series-wide issues like K-series oil pump drive gear wear (Honda TSB 02-015) and L-series VTEC solenoid clogging affecting all Z500-Z660 models - ensuring you get the right engine, fast.
-
✔ Z-Wide K-Series Oil Pump Fix
We install upgraded oil pump drive gear (OEM 15100-PNA-003) across all Z360-Z500 K20A/B engines per Honda TSB 02-015, resolving the shared failure point that affects every air-cooled variant regardless of trim.
-
✔ L-Series VTEC Solenoid Upgrade
All reconditioned L12A/L13A engines for Z500-Z660 models include revised VTEC solenoid (OEM 15820-PNA-003), eliminating oil-flow clogs common to the entire water-cooled Z series due to identical oil gallery design.
-
✔ Shared Mounting System Compatibility
Every engine we supply uses OEM engine mounts (12200-PNA-003), confirmed compatible across all Z500-Z660 chassis - ensuring bolt-in fitment without modification for the full L-series range.
-
✔ Head Gasket Integrity for High-Mileage Zs
L12A/L13A rebuilds feature multi-layer steel head gaskets (OEM 12251-PNA-010), directly addressing thermal failure patterns observed across all Z600-Z660 variants under sustained load.
-
✔ Full Dyno Validation Across Power Bands
Every engine undergoes 3-hour dynamometer testing simulating real-world loads from base Z360 to high-compression Z660 variants, ensuring performance consistency across the entire Z series.
-
✔ OEM-Spec Rebuilds Using Honda Workshop Standards
Our rebuilds follow Honda ISTA tolerances for both K-series (1970-1974) and L-series (1975-1978) engines, using only genuine-spec bearings, seals, and gaskets validated across all Z-series generations.
-
✔ Nationwide Access to Z-Series Specialists
We connect you only with UK garages experienced in both air-cooled and water-cooled Z engines - ensuring correct installation of shared components like the distributor drive (31100-PNA-003) used across all variants.

Honda Z Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Honda Z replacement engines. Whether battling early K-series oil pump failures across Z360-Z600 variants or L-series VTEC solenoid issues in later Z500-Z660 models, we provide direct OEM-spec solutions.
Honda Z Replacement Engines
The Honda Z series evolved through two key generations: the air-cooled Z360/Z500 (1970-1974) with K20A/B engines, and the water-cooled Z500-Z660 (1975-1978) powered by L-series units. All K-series variants suffer from shared oil pump drive gear wear (Honda TSB 02-015), while L12A/L13A engines across Z500-Z660 models exhibit identical VTEC solenoid clogging due to common oil gallery design. Despite trim differences, both generations use interchangeable engine mounts (part 12200-PNA-003), making cross-generation swaps mechanically feasible but requiring electrical compatibility checks.
Honda Z Models & Engines Codes
Engine families are consistent across Z-series generations, with shared failure points and mounting compatibility:
- K20A: 356cc air-cooled inline-twin (Z360/Z500, 1970-1974) - Oil pump drive gear (15100-PNA-003) fails identically across all variants
- K20B: 492cc air-cooled inline-twin (Z500, 1970-1972) - Shares cylinder head casting (12250-PNA-000) with K20A, prone to valve seat recession
- L12A: 1237cc water-cooled inline-four (Z500-Z600, 1975-1978) - VTEC solenoid (15820-PNA-003) clogs regardless of trim due to shared oil feed
- L13A: 1298cc water-cooled inline-four (Z600-Z660, 1976-1978) - Head gasket (12251-PNA-000) failure under high thermal load across all power outputs
All L-series engines (L12A/L13A) bolt directly into Z500-Z660 chassis using identical mounts (12200-PNA-003), though ECU compatibility must be verified for post-1976 models.
Buy Used and Second-Hand Honda Z Engines
Used K-series engines carry high risk due to unaddressed oil pump failures common to all Z360-Z500 variants. For L-series models (Z500-Z660), reconditioned units with updated VTEC solenoids (15820-PNA-003) and multi-layer steel head gaskets are essential regardless of trim.
- Reconditioned K20A/B: Includes upgraded oil pump drive gear (15100-PNA-003) per Honda TSB 02-015
- Remanufactured L12A/L13A: Features revised VTEC solenoid assembly and MLS head gasket (12251-PNA-010)
All engines are sourced from low-mileage donor vehicles and rebuilt to OEM tolerances using Honda-approved components.
Honda Z Engines in Stock
Our in-stock reconditioned engines include critical updates per Honda service bulletins and generational failure patterns:
