Honda Integra Engine ReplacementRebuilt & Performance Options Available

Honda Integra engine replacement costs range from £1,200 for a used B18B to £4,500 for a rebuilt K20A. Rebuilt B18C Type R engines typically cost £1,695-£2,500 supply-only.

• Used engines start around £950-£1,200 for budget builds
• Rebuilt B18C engines: £1,695-£2,500 supply-only
• K20A DC5 Type R rebuilt: £2,800-£4,500 supply-only
• Supply & fit labour adds £450-£1,200 depending on complexity

The DC2 Integra Type R uses the B18C engine: JDM versions produce 200ps (197bhp), while UKDM B18C6 units produce 190bhp with lower compression.

• B18C: 1.8L DOHC VTEC, hand-built, 190-200hp
• JDM B18C: 11.1:1 compression, 200ps, requires 98 RON fuel
• UKDM B18C6: 10.6:1 compression, 190bhp, OBD2
• All B18C variants use timing BELT, replace every 60k miles

Yes, K-swapping a K20A or K20A2 into a DC2 Integra is common but requires custom mounts, wiring, and ECU work, with total costs of £4,000-£8,000.

• K20A2 from EP3 Civic Type R is a popular swap donor
• Requires K-series engine mounts, wiring harness, and ECU
• Budget £4,000-£8,000 for full professional K-swap
• Retains VTEC/i-VTEC with modern drive-by-wire benefits

Yes, B18C and K20A engines are robust when maintained, but watch for VTEC solenoid issues, timing belt neglect on B-series, and oil consumption on high-mileage examples.

• B-series: Replace timing belt every 60k miles to avoid catastrophic failure
• VTEC solenoid failure common at 40k-80k miles on B18C
• K20A: VTC actuator rattle on cold start, but timing chain is more reliable
• Regular oil changes with 5W-40 synthetic critical for VTEC longevity

B18C and B16A engines in DC2/DA6 Type R models use a timing BELT requiring replacement every 60,000 miles. The DC5 K20A uses a timing CHAIN.

• B-series (B16A, B18C, B18B): Timing BELT, 60k mile interval
• K-series (K20A): Timing CHAIN, tensioner can wear but less frequent service
• Belt failure on B-series causes catastrophic valve damage (interference engine)
• Always replace water pump and tensioner during belt service

Yes, rebuilding a B18C is worthwhile for genuine Type R owners, costing £2,000-£3,500 versus £1,695-£2,500 for a pre-rebuilt unit with warranty.

• Rebuild costs £2,000-£3,500 if block is in good condition
• Pre-rebuilt units from £1,695 include warranty and testing
• Upgraded valve seals and piston rings address oil consumption
• Ideal for preserving a genuine Type R's value and performance

JDM B18C produces 200ps with 11.1:1 compression; UKDM B18C6 produces 190bhp with 10.6:1 compression and OBD2 emissions equipment.

• B18C (JDM): 200ps, 11.1:1 compression, OBD1, requires 98 RON
• B18C6 (UKDM): 190bhp, 10.6:1 compression, OBD2, runs on 95 RON
• Both share same block architecture and VTEC system
• B18C6 is more common and often cheaper for UK replacements

A K-swap replaces the original B-series engine with a K20A or K24 from a later Honda, offering more power, modern electronics and improved reliability.

• Popular donors: EP3 Civic Type R (K20A2), DC5 Type R (K20A)
• Requires custom mounts, wiring harness, ECU and often gearbox
• Total cost £4,000-£8,000 for professional installation
• Delivers 200-220hp with i-VTEC and drive-by-wire throttle

Use 5W-40 fully synthetic oil for B18C engines to maintain VTEC oil pressure; change every 5,000-7,500 miles for optimal longevity.

• B18C requires 5W-40 fully synthetic for VTEC solenoid operation
• Change interval: 5,000 miles for track use, 7,500 for road
• Use Honda-spec or ACEA A3/B4 rated oils
• Monitor oil level monthly; top up if consumption exceeds 1L/1,000 miles
