Honda SMS Engine ReplacementCompare Prices & Save

The F20C is fundamentally robust but has known failure points. With proper maintenance, many exceed 150k miles. Timing chain tensioners and oiling system care are critical for longevity.

• F20C engines often reach 150k+ miles with proper maintenance
• Timing chain tensioner replacement recommended at 60k-80k miles
• Regular oil changes with correct viscosity prevent starvation issues
• VTEC system requires clean oil to function reliably

Oil starvation in AP1 SMSs typically stems from the oil pump pickup banjo bolt screen clogging with debris, restricting flow to critical components like VTEC and timing chains.

• Banjo bolt screen clogs with carbon and metal particles over time
• Restricted oil flow affects VTEC engagement and chain tensioners
• Symptoms include VTEC not engaging or timing rattle on startup
• Prevention: frequent oil changes, quality filters, screen inspection

Rebuilt Honda SMS engines typically cost £2,500-£5,000 supply-only, depending on engine code, variant and specification. Supply & fit adds £800-£1,500 labour.

• F20C rebuilt units: £2,500-£4,200 typical range
• F22C rebuilt units: £2,800-£5,000 typical range
• Final Edition and low-mileage units command premium pricing
• Supply & fit labour adds £800-£1,500 depending on location

For engines under 70k miles with isolated issues, repair may be viable. For high-mileage units or multiple failures, a rebuilt engine with upgraded components offers better long-term value.

• Minor repairs viable only if block and internals are sound
• Rebuilt engines include warranty and address known failure points
• Labour costs for complex repairs often approach rebuild pricing
• Consider vehicle value and intended use in decision-making

The F20C is a 2.0L unit with 9,000rpm redline for AP1 models; the F22C is 2.2L with 8,200rpm redline for AP2, offering broader torque with similar peak power.

• F20C: 1,997cc, 9,000rpm redline, AP1 models (1999-2003)
• F22C: 2,157cc, 8,200rpm redline, AP2 models (2004-2009)
• Both produce ~240hp but F22C has stronger mid-range torque
• F22C has slightly revised oiling and VTEC components

Yes, common upgrades include supercharger kits, high-compression pistons, and camshaft changes. However, ensure the base engine is sound before investing in performance modifications.

• Supercharger kits add 100-150hp with proper supporting mods
• High-compression pistons and cams improve naturally aspirated output
• Upgraded oiling and cooling are essential for any power increase
• Rebuilt engines can be spec'd with performance components from the start

Your engine code is stamped on the block and can be verified instantly by entering your registration number. F20C variants powered AP1 models; F22C variants powered AP2 models.

• Engine code stamped on block near cylinder head
• DVLA lookup via registration confirms exact specification
• AP1 models (1999-2003) use F20C, F20C1 or F20C6
• AP2 models (2004-2009) use F22C1 or F22C2

Used engines can offer budget replacement if sourced from reputable breakers with compression and leak-down verification. Always request donor vehicle history and warranty terms.

• Used F20C/F22C engines typically £1,800-£3,200 supply-only
• Request compression test results and leak-down verification
• Confirm donor vehicle mileage and service history
