• These are UK independent specialist estimates ; main dealers will be significantly higher.
• Prices vary based on whether the replacement includes carbon cleaning and a new high-pressure fuel pump.
• Always get three quotes to compare.

The most frequently reported issues are carbon buildup on intake valves (typically 40,000-80,000 miles) and high-pressure fuel pump failure (50,000-100,000 miles). Compare prices for an 8AR-FTS with carbon cleaning and HPFP already addressed

• Carbon cleaning (walnut blasting) costs £400-£800 .
• HPFP replacement costs £500-£1,200 .
• Water pump leaks are another known maintenance item (£400-£800).
• None of these are catastrophic if addressed promptly - the 8AR-FTS is generally very durable.

The 8AR-FTS is fitted to: It is the first Lexus mass-market turbo petrol engine since the 2JZ-GTE. See the full compatibility list above

• Lexus IS200t (GSE30, 2015-2020)
• Lexus NX200t (AZ10, 2015-2021)
• Toyota Crown 2.0T (JDM, S210/S220)
• Toyota Harrier 2.0T (JDM, XU60)

For lower-value vehicles (e.g. an older IS200t under £5,000), a used engine with a solid warranty is often the most sensible choice, provided the donor has documented service history and ideally a recent carbon clean. For cars worth £6,000+, a reconditioned unit is the sweet spot - it comes with professional decarbonisation, a new high-pressure fuel pump, fresh water pump, and a 12-24 month warranty. Rebuilt engines are only recommended for very low-mileage or cherished examples. Compare used vs reconditioned 8AR-FTS prices

• Always confirm the replacement unit has addressed carbon buildup and the HPFP.

The engine code is stamped on the block (typically on the front side, just below the cylinder head on the driver's side) and is also on your V5C under “Engine number”. Alternatively, enter your registration above and we'll confirm your exact fitment. Check your engine via registration

• Don't confuse it with the 8NR-FTS (1.2-litre turbo) - they are not interchangeable.
• If your IS or NX is badged "200t" with a 2.0-litre turbo petrol engine, it's almost certainly the 8AR-FTS.

With proper maintenance, the 8AR-FTS is expected to exceed 200,000 miles. The engine is chain-driven, so no timing belt replacement is needed. Regular oil changes (every 10,000 miles or 12 months, using the correct 0W-20) and premium fuel (to minimise carbon buildup) are critical to longevity. The carbon buildup is a service item, not a terminal failure - a walnut-blast every 60,000-80,000 miles keeps it fresh. The HPFP is a wear item that should be addressed if symptoms appear. With these maintenance items observed, the 8AR-FTS is a robust and durable turbo petrol.
