The Peugeot 5GP (EP6FDTR) is a 1,598 cc, inline‑four turbo‑petrol engine produced between 2015 and 2021. It features direct fuel injection, a twin — scroll turbocharger, and dual overhead camshafts (DOHC) with variable valve timing. This high — performance variant delivers 220 kW (300 PS) and 330 Nm of torque, with the twin — scroll turbo providing immediate throttle response for track — focused driving.
Exclusively fitted to the Peugeot 308 II GTi 300, the 5GP was enginee…
Production years 2015–2016 meet Euro 6 standards; 2017–2021 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/8890).
The Peugeot 5GP (EP6FDTR) is a 1,598 cc inline‑four turbo‑petrol engineered for high-performance hot hatches (2015-2021). It combines direct fuel injection with a twin-scroll turbocharger to deliver exceptional specific output and razor-sharp throttle response. Designed to meet Euro 6 and Euro 6d-TEMP standards, it prioritizes track-ready performance without sacrificing regulatory compliance.

The Peugeot 5GP (EP6FDTR) was used exclusively in Peugeot's flagship hot hatch with transverse mounting. This engine received model-specific adaptations-unique engine mounts, a larger intercooler, and a bespoke ECU calibration for the 308 GTi 300-with a mid-cycle update in late 2017 introducing the revised fuel pump. All adaptations are documented in OEM technical bulletins.
The 5GP (EP6FDTR)'s primary reliability risk is high-pressure fuel pump failure under track or aggressive driving conditions, with elevated incidence in vehicles subjected to sustained high RPM. PSA internal durability testing indicated a higher failure rate for units produced before Q4 2017, while UK DVSA records show no significant pattern of emissions test failures for these models. Use of incorrect fuel and irregular maintenance cycles are the leading causes of catastrophic engine failure.
Analysis derived from PSA Group technical bulletins (2015-2021) and UK DVSA failure statistics (2018-2024). 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 5GP is a track-focused engine that demands meticulous care. Its main weakness is the high-pressure fuel pump on pre-late 2017 models under extreme use. With the revised pump, strict 10,000 km oil changes, mandatory intake cleaning, and exclusive use of 98 RON fuel, it can be reliable. However, it is not a low-maintenance engine.
The most critical issues are high-pressure fuel pump failures (early models under stress), severe intake valve carbon buildup, turbocharger compressor damage from debris, and timing chain tensioner failure. These are well-documented in PSA service bulletins, with specific part number updates available for the fuel pump.
This 1.6L turbo petrol engine was used exclusively in one model: the Peugeot 308 II GTi 300 (2015-2021). It was the most powerful and track-focused iteration of the Prince engine family ever produced by Peugeot, featuring a Torsen limited-slip differential and bespoke chassis tuning.
Yes, but with significant caveats. The stock engine is already at its limit. A conservative Stage 1 remap might yield 330-340 PS. To go further, forged internals, a larger turbo, and upgraded fueling are mandatory. Pushing beyond 350 PS drastically reduces engine lifespan and reliability. Professional tuning on a dyno is essential.
Official combined figures are around 6.5 L/100km (43 mpg UK). Real-world economy is highly dependent on driving style: expect 10.0-15.0 L/100km (28-19 mpg UK) in spirited or track driving, dropping to 7.5-8.5 L/100km (38-33 mpg UK) on gentle highway runs. Aggressive driving will consume fuel rapidly.
Yes. Like all modern engines, the 5GP is an interference design. If the timing chain were to fail or jump due to tensioner wear, the pistons would collide with the open valves, causing catastrophic internal engine damage requiring a full rebuild or replacement.
It requires a high-quality, full synthetic 5W-30 oil meeting the PSA B71 2290 specification. This is non-negotiable for protecting the turbocharger and timing chain under high stress. Change intervals must not exceed 10,000 km or 12 months, whichever comes first, especially for track-driven vehicles.
