Mitsubishi Mirage Engine ReplacementCompare Prices & Save

Compatibility depends entirely on your Mirage generation. Modern 2012+ models use 3A92/3G83 1.2L engines; classic 1990s-2000s models use 4G13/4G15/4G92/4G93 series. Never assume interchangeability between generations.

• Modern Mirages (2012+) exclusively use 3A92 or 3G83 1.2L engines
• Classic Mirages (1990-2002) use 4G13, 4G15, 4G92 or 4G93 engines
• Engine mounts, ECU and transmission interfaces differ completely between generations
• Always verify your engine code via registration check before ordering

Rebuilt Mirage engine prices range from £550 for classic 4G13 units to £2,500 for performance 4G92 MIVEC engines. Modern 3A92 replacements typically cost £800-£1,900 supply-only.

• Classic 4G13/4G15 engines: £550-£1,400 rebuilt supply-only
• Modern 3A92/3G83 engines: £800-£1,900 rebuilt supply-only
• Performance 4G92 MIVEC: £1,400-£2,500 rebuilt supply-only
• Supply & fit labour adds £300-£600 depending on location

Weak factory piston rings on the 3A92 engine allow oil to enter the combustion chamber, causing excessive consumption typically from 40,000-80,000 miles.

• Factory piston ring design is the root cause on 3A92 engines
• Consumption worsens with mileage and hard driving
• Rebuilt engines with upgraded rings solve the issue permanently
• Monitor oil level weekly if consumption exceeds 1L per 1,000 miles

The 3A92 timing chain can stretch or suffer phaser wear around 80,000-120,000 miles despite Mitsubishi's "lifetime" claims, leading to rattling noise and potential valve timing loss.

• Chain tensioner and phaser wear cause slack over time
• Rattling noise on cold start is the primary warning sign
• Preventative chain kit replacement costs £600-£1,100 specialist
• Full engine replacement recommended if chain has jumped

No - the 4G92 1.6L engine will not directly fit a 4G15 1.5L Mirage without extensive modification to mounts, wiring, ECU and transmission.

• Engine mounts, wiring looms and ECUs are generation-specific
• Transmission bellhousing patterns differ between 4G15 and 4G92
• MIVEC engine swaps require custom fabrication and tuning
• For reliability, fit the correct engine code for your chassis

With proper maintenance, classic 4G15 engines often exceed 150,000 miles; modern 3A92 units typically reach 140,000-170,000 miles before major issues arise.

• 4G15 engines known for longevity with regular oil changes
• 3A92 engines prone to oil consumption from 40k miles
• Timing chain maintenance critical for 3A92 beyond 80k miles
• Service history significantly impacts actual lifespan

Wear in the throttle position sensor or motor within the electronic throttle body causes erratic response, triggering ECU limp mode on modern 3A92-equipped Mirages.

• Throttle position sensor wear is the most common cause
• Symptoms include poor throttle response, stalling, limp mode
• Replacement throttle body costs £350-£700 fitted specialist
• Rebuilt engine replacement only needed if secondary damage occurred
