Nissan Silvia Engine ReplacementRebuilt & Performance Options Available

Rebuilt Nissan Silvia engines typically cost £1,500-£4,500 depending on engine code and variant. CA18DET units start around £1,500, while S15 Spec R SR20DET rebuilt engines reach £4,500.

• CA18DET rebuilt: £1,500-£2,200 supply only
• SR20DET rebuilt: £2,200-£4,500 depending on generation
• Used engines available from £800 but verify compression first
• Supply & fit labour adds £800-£2,500 depending on workshop

NVCS rattle from worn solenoid or sprocket is the most reported SR20DET issue on S14/S15 models, followed by coil pack failure causing misfire under boost.

• NVCS rattle appears 80k-120k miles, metallic ticking from cylinder head
• Coil pack failure causes misfire under load, easy diagnostic scan
• Head gasket failure common on high-boost or overheated engines
• CAS failure can cause no-start conditions on high-mileage units

The CA18DET can be reliable for daily use if maintained, but timing chain stretch after 80k miles and head gasket vulnerability require proactive maintenance or rebuilt replacement.

• Timing chain tensioner upgrade recommended at 80k miles preventative
• Head gasket failure risk increases with boost or poor cooling
• Lighter than SR20DET, popular for budget drift builds
• Rebuilt units with MLS gasket offer best long-term reliability

S15 SR20DET features upgraded T28 turbo with inconel wheel, 444cc injectors (vs 370cc), and 247-250bhp output versus S14's 217bhp, plus refined ECU mapping.

• S15 turbo more robust but same seal failure vulnerability
• Larger injectors support higher power potential on S15
• Both share NVCS VVT system and common failure points
• S15 Spec R commands premium pricing for replacement engines

Yes, RB25DET swaps into S13/S14/S15 are popular but require custom engine mounts, wiring harness adaptation, and ECU tuning from a specialist familiar with Silvia chassis.

• RB25DET offers 250bhp straight-six smoothness and torque
• Custom mounts and transmission adapter required for fitment
• Wiring/ECU integration needs specialist knowledge
• Budget £2,500-£4,200 for rebuilt RB25DET plus swap labour

A properly rebuilt SR20DET with upgraded components should deliver 100k+ miles of reliable service, with NVCS and coil pack maintenance extending lifespan further.

• Rebuilt engines include new bearings, seals, MLS gasket as standard
• NVCS solenoid service recommended every 60k miles preventative
• Coil packs should be replaced proactively at 80k miles
• 12-month unlimited mileage warranty standard on rebuilt units

White smoke typically indicates head gasket failure (coolant burning) or turbo seal failure (oil burning) on SR20DET/CA18DET engines - compression test diagnoses root cause.

• Sweet smell suggests coolant burning: head gasket failure likely
• Blue-tinged smoke suggests oil burning: turbo seal failure probable
• Compression test and leak-down test confirm diagnosis
• Rebuilt engine with MLS gasket resolves head gasket issues permanently

For clean-chassis S13 models, rebuilding CA18DET/SR20DET engines is cost-effective versus replacement; for rusted or modified cars, consider part-out value versus rebuild investment.

• Rebuild CA18DET: £1,500-£2,200 versus used £800-£1,800
• S13 chassis values rising; quality rebuild protects investment
• Factor in timing chain, head gasket, turbo condition in decision
• Specialist rebuilders offer warranty protection versus breaker units

Rebuilt and reconditioned Nissan Silvia engines supplied through EngineMarket include a minimum 12-month unlimited mileage warranty; used engines typically carry 3-6 months.

• 12-month warranty standard on rebuilt/reconditioned units
• Warranty covers parts and labour at supplying specialist
• Used engine warranties shorter; verify terms before purchase
• Extended warranty options available for forged performance builds

Engine code is stamped on the block near the bellhousing; SR20DET, CA18DET, RB20DET or RB25DET will be clearly marked. Enter your reg above for instant DVLA verification.

• SR20DET: 2.0L turbo, most common replacement engine
• CA18DET: 1.8L turbo, early S13 models only
• RB codes: straight-six swaps, require custom fitment
• DVLA lookup via registration confirms exact variant and engine
