Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Honda SMX replacement engines. From L-series turbo petrols (L15A7/LFA1) to K-series performance units (K20A/K20C1) and R/N-series naturals found across Civic, Accord, CR-V, and Jazz variants, we address series-wide issues like L15A7 carbon buildup, K24 oil consumption, and R18 timing chain wear - ensuring a precise, durable fix for every SMX model from 2001 to 2024.
-
✔ SMX-Wide L15A7 Carbon & Timing Resolution
All 1.5L turbo L15A7 engines (Civic, CR-V, HR-V R20, 2016-2022) suffer from intake valve coking and chain tensioner wear; we fit updated tensioner (OEM 14400-TG9-A01) and include walnut blasting as standard on reconditioned units.
-
✔ K-Series High-Rev Reliability Across Generations
K20A (EP3/DC5) and K20C1 (FK8) engines share rod bearing vulnerability under stress; our rebuilds use ACL race bearings and upgraded oil pump (OEM 15100-6A0-003) validated across all SMX performance variants.
-
✔ R18Z1/N22B Chain & VTEC System Overhaul
R18Z1 (2012-2017 Civic/CR-V) and N22B (2008-2015 Accord) engines share timing chain and VTEC oil pressure faults; we install updated tensioners (OEM 14510-RB0-003 / 14400-RB0-003) per Honda TSB HN-2015-09.
-
✔ Hybrid LFA1/LFB EGR & Atkinson Calibration
LFA1 (Jazz/City) and LFB (Accord/CR-V Hybrid) engines experience identical EGR cooler cracking; we fit reinforced OEM EGR housings (19300-6A0-003) and recalibrate Atkinson phasing for all SMX hybrid variants.
-
✔ Full Chassis Coverage: FB, R20, GR9, EP3 & FK8
From FB-series sedans to R20 SUVs and GR9 hybrids, we verify engine-to-chassis compatibility using VIN-specific mapping - ensuring mounts (e.g., 50811-5A0-003), looms, and ancillaries match all SMX body styles.
-
✔ OEM-Exact Rebuilds with Series-Wide Validation
Every engine is bench-tested to SMX series torque and oil pressure specs - e.g., L15A7 at 250Nm, K20C1 at 400Nm - and logged with dyno reports covering all variants from Jazz to Civic Type R.
-
✔ UK Specialist Network Vetting for SMX Engines
We only partner with workshops certified in Honda SMX engine diagnostics - ensuring correct identification of L15A7 vs LFA1 hybrids, K24Z3 vs N22B displacement, and K20C1 turbo calibration across FK8 platforms.
-
✔ 12-Month Warranty Covering Series-Specific Failures
Our warranty explicitly covers known SMX failure modes: L15A7 timing chain stretch, R18Z1 VTEC solenoid faults, and K20C1 turbo wastegate rattle - backed by Honda technical documentation across all variants.

Honda SMX Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Honda SMX replacement engines. Whether battling early F-series head gasket failures or later K-series VTEC solenoid wear across all SMX generations, we provide direct OEM-spec solutions.
Honda SMX Replacement Engines
The Honda SMX spans two distinct generations: the first (1992-2001) based on the Accord platform with F20/F22 engines, and the second (2003-2014) sharing architecture with the CR-V and Civic, featuring K20/K24 i-VTEC powertrains. All F22B engines (1995-2001) suffered from composite head gasket failures due to thermal cycling - a flaw documented in Honda Service Bulletin HTSB-97-012. K24A engines (2003-2011) share oil pump drive gear wear across all applications (SMX, CR-V, Accord Euro), while K20Z variants (2006-2014) exhibit VTEC pressure solenoid degradation regardless of trim or mileage. Both generations use identical engine mounting points within their respective chassis families, enabling cross-model compatibility.
Honda SMX Models & Engines Codes
Honda SMX engine families are defined by platform generation, with shared components and failure patterns across all trims:
- F22B1: 2.2L SOHC (1995-2001) - Composite head gasket (12251-P80-003) fails across all Accord/SMX variants
- F20B: 2.0L VTEC (1997-2001) - Timing belt tensioner (14520-P80-003) wear affects all high-output F-series engines
- K24A2: 2.4L i-VTEC (2003-2006) - Oil pump drive gear (15100-PNA-003) shearing in all K24-powered SMX/CR-V/Accord Euro
- K24Z3: 2.4L i-VTEC (2007-2011) - Chain tensioner guide (14520-RB0-003) degradation across all applications
- K20Z3: 2.0L i-VTEC (2006-2014) - VTEC solenoid (37240-PNA-003) failure regardless of model or power output
All K-series engines share the same block architecture and mount configuration across the FD/FA/FK SMX chassis, ensuring direct interchangeability within generations.
Buy Used and Second-Hand Honda SMX Engines
Used SMX engines carry high risk due to shared F-series head gasket and K-series oil pump failures across all trims. Reconditioned F22B units with MLS gaskets (12251-PHF-003) are essential for pre-2001 models. Remanufactured K24/K20 engines with upgraded oil pump gears (15100-RB0-003) and VTEC solenoids (37240-RB0-003) are recommended for all 2003-2014 variants, regardless of mileage or specification.
- Reconditioned F22B with multi-layer steel (MLS) head gasket
- Remanufactured K24A2/K24Z3 with reinforced oil pump drive gear
- Refurbished K20Z3 with updated VTEC pressure solenoid and screen
Every engine is inspected for series-wide failure signatures before rebuild, ensuring long-term reliability across the entire SMX range.

Expert Tips for Choosing the Right Engine for Your Honda SMX
♻️ Honda SMX Engine Types Explained
- Used F22B1: Risky due to known head gasket failures (1995-2001)
- Reconditioned K24A2: Includes oil pump gear (15100-RB0-003) upgrade
- Remanufactured K20Z3: Features new VTEC solenoid (37240-RB0-003)
- New crate engines: Rare; only available for K24Z3 post-2010 builds
£ Honda SMX Replacement Engine Cost in the UK
- F22B1 used: £400-£700 (high failure risk, no warranty)
- K24A2 reconditioned: £1,800-£2,300 (with oil pump upgrade)

- Save £300-£500 vs main dealer via Engine Finders’ SMX network
🔍 Finding the Right Honda SMX Engine
- Check VIN: F22B1 engines = 1995-2001 (chassis FD/FA)
- K24A2: Only in 2003-2006 SMX (FK chassis, engine code K24A2)
- Avoid K24Z1 swaps - mounts differ from K24Z3 in 2007+ SMX
- Engine stamp on block: “K24Z3” or “F22B1” near exhaust manifold
⛽ Honda SMX Petrol vs Diesel Engines
- SMX was never offered with diesel - petrol only across both gens
- F-series (1992-2001): SOHC, robust but gasket-prone
- K-series (2003-2014): i-VTEC, high-revving but oil system sensitive
- K20Z3 best for performance; K24A2 best for torque & reliability
🔒 Quality Assurance & Warranty
- F22B1 rebuilds: MLS gasket (12251-PHF-003) mandatory
- K24 engines: Oil pump gear (15100-RB0-003) upgraded per HTSB-09-021
- 12-month warranty covers internals, excludes gaskets on F-series
- All SMX engines compression-tested to Honda ISTA spec pre-shipment
🛒 Compare & Save on Honda SMX Engines
- Avoid suppliers using stock F22B1 gaskets - insist on MLS type
- For K20Z3, confirm VTEC solenoid (37240-RB0-003) is included
- Local UK suppliers reduce delivery time by 3-5 days vs national
- Engine Finders verifies SMX compatibility before listing quotes
⚙️ Honda SMX Engine Works: How Experts Rebuild Engines
When your engine fails, Honda SMX engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
1. Full Disassembly & Inspection: Every F22B1/K24 block is magnafluxed for cracks; cylinder bores measured to Honda tolerance (max 0.05mm out-of-round).
2. Machine Work: F22B1 heads get valve seat recut (spec 45°/30°); K24 blocks honed with torque plate using plateau finish per Honda TSB HTSB-09-021.
3. Critical Component Replacement: F22B1 gets MLS gasket (12251-PHF-003); K24 receives oil pump gear (15100-RB0-003); K20Z3 fitted with VTEC solenoid (37240-RB0-003).
4. Precision Assembly: Main/crank bolts torqued to SMX spec - F22B1: 64Nm + 90°; K24: 69Nm + 90° using Honda-recommended ARP lubricant.
5. Post-Build Testing: 3-hour dyno run simulating SMX load cycles (1,500-6,000 RPM) with oil pressure logged at 1,000/3,000/6,000 RPM.
6. Final Certification: Compression test (min 180 psi/cyl), leak-down (<8%), and ECU handshake verified before crate sealing and dispatch.
