A rebuilt Peugeot 207 GTi 1.6 THP engine typically costs **£1,300-£2,800** supply-only, depending on supplier and condition. Used engines start from **£800**. Supply & fit adds **£450-£900** labour. Main dealer replacement can exceed **£4,000**.

• Rebuilt 5FY: £1,300-£2,800
• Reconditioned 5FY: £1,300-£2,000
• Used 5FY: £800-£1,500

The most common Peugeot 207 GTi 1.6 THP (5FY / EP6DTS) engine problems are **timing chain stretch and tensioner failure** causing cold-start rattle, **high-pressure fuel pump (HPFP) failure** causing hard starting and misfires, **carbon buildup on intake valves** from direct injection, and **turbocharger oil feed line leaks**. The 5FY 175hp variant is particularly susceptible to HPFP failure and timing chain guide wear.

• Timing chain rattle on cold start (common from 40k-80k miles)
• HPFP failure causing hard starting and misfires
• Carbon buildup causing rough idle and power loss
• Turbo oil feed leaks leading to turbo failure

Replacing a Peugeot 207 GTi 1.6 THP engine is worthwhile if the vehicle is otherwise sound and the replacement cost stays below the vehicle's value. With 207 GTi values typically **£2,500-£7,000**, a rebuilt engine at **£1,300-£2,800** represents a significant investment but often makes sense for well-maintained examples. For sub-£3,000 examples, a used engine from £800 may be more economical. The 5FY's performance potential often justifies the investment.

• Rebuilt 5FY: £1,300-£2,800
• Used 5FY: £800-£1,500
• Dealer replacement: £2,800-£4,000+

With proper maintenance, the Peugeot 207 GTi 1.6 THP (5FY / EP6DTS) engine can reach **100,000-130,000 miles**. However, timing chain issues can appear as early as **40,000 miles**, and HPFP failure from **50,000 miles**. Regular oil changes with correct PSA-approved oil, timely timing chain replacement and HPFP monitoring are essential for longevity.

• Timing chain inspection recommended from 40,000 miles
• HPFP failure common from 50,000 miles
• Carbon cleaning recommended every 40,000-60,000 miles
• Regular oil changes with correct spec critical for turbo health

The 207 GTi uses the **5FY (EP6DTS)** engine producing **175hp**, while the 207 GT uses the **EP6DT (5FX)** engine producing **150hp**. Both use the same 1.6L Prince architecture, but the 5FY has a higher-output calibration, larger turbocharger and more aggressive engine mapping. The 5FY is also more susceptible to HPFP failure and timing chain guide wear due to higher cylinder pressures. The GTi also features an overboost function taking torque to 260 Nm.

• 207 GTi: 5FY, 175hp, 260 Nm overboost
• 207 GT: EP6DT, 150hp
• GTi more powerful but more vulnerable to HPFP and timing chain issues
