The Peugeot 5FT (EP6DT) is a 1,598 cc, inline‑four turbo‑petrol engine produced between 2010 and 2015. It features a 16‑valve DOHC layout with variable valve timing (VVT) and direct fuel injection, paired with a twin‑scroll turbocharger to deliver 156 kW (211 PS) and 275 Nm of torque. This compact powerplant was engineered for responsive performance, offering strong low‑end pull and linear power delivery.
Fitted primarily to sporty variants of the 308 and RCZ, the 5FT wa…
Production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/PSA/5FT).
The Peugeot 5FT (EP6DT) is a 1,598 cc inline‑four turbo‑petrol engineered for compact performance models (2010-2015). It combines gasoline direct injection with a twin‑scroll turbocharger to deliver sharp throttle response and high specific output. Designed to meet Euro 5 standards, it balances sporty performance with acceptable fuel economy.

The Peugeot 5FT (EP6DT) was used across Peugeot's PF2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the RCZ-and no significant facelift revisions occurred during its production run, ensuring broad parts compatibility. All adaptations are documented in OEM technical bulletins.
The 5FT's primary reliability risk is timing chain tensioner wear, with elevated incidence in vehicles using incorrect oil or exceeding service intervals. PSA internal data indicated a notable failure rate before 120,000 km in affected batches, while owner reports frequently cite a distinctive rattle on cold start. Poor oil quality increases tensioner stress, making oil specification and adherence to service schedules critical.
Analysis derived from PSA technical bulletins (2010-2015) and owner-reported failure data (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 5FT offers exhilarating performance but has known issues, primarily the timing chain tensioner. With meticulous maintenance, using the correct 5W-40 oil and adhering to service schedules, it can be reliable. Later examples or those with the updated tensioner are generally more robust.
The most frequent issues are timing chain tensioner wear, high-pressure fuel pump failure, intake valve carbon buildup, and turbocharger wastegate actuator faults. These are well-documented in PSA service bulletins and owner forums, often linked to maintenance or fuel quality.
This 1.6 THP 200 engine was used in the high-performance Peugeot 308 GTI (200/208) and the Peugeot RCZ (including the RCZ R) from 2010 to 2015. It was the highest-output variant of the EP6 engine family in Peugeot vehicles.
Yes, ECU remapping is very common and can yield safe power gains of +30-50 kW. The engine's internals and turbo are robust. However, increased power puts more strain on the clutch, turbo, and fuel system, so supporting modifications and enhanced maintenance are recommended for stage 2+ tunes.
In a Peugeot 308 GTI, expect combined fuel economy of approximately 7.5 L/100km (38 mpg UK). Highway driving can return ~6.0 L/100km (47 mpg UK), while spirited city driving may consume ~10.5 L/100km (27 mpg UK). Real-world figures vary significantly with driving style.
Yes. The 5FT is an interference engine. If the timing chain jumps or the tensioner fails catastrophically, the pistons can collide with the open valves, causing severe internal damage. Regular inspection for tensioner wear is advised.
Peugeot mandates oil meeting the PSA B71 2312 specification, typically a 5W-40 synthetic. Using the correct oil is vital for protecting the turbocharger, timing chain tensioner, and high-pressure fuel pump. Never use a lower specification oil.
