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 engineered for maximum power and agility in a hot hatch format. Emissions compliance was achieved through a high-flow catalytic converter and precise engine management, enabling compliance with the stringent Euro 6 and Euro 6d-TEMP emissions standards.
One documented concern involves potential high-pressure fuel pump failure under extreme conditions, which can cause sudden power loss. This issue, referenced in Peugeot Service Bulletin 9023C, is linked to sustained high-rpm operation. Production from late 2017 incorporated a revised pump design with enhanced durability for performance applications.
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 extreme specific output demands strict adherence to 10,000 km or 12-month oil change intervals using PSA B71 2290 specification oil to protect the turbo and timing chain. The direct injection system is highly prone to intake valve carbon buildup; periodic cleaning is mandatory for sustained performance. Vehicles built before November 2017 should have the high-pressure fuel pump inspected or updated per Service Bulletin 9023C. Use of 98 RON premium fuel is non-negotiable for engine protection and performance.
Oil Specs: Requires PSA B71 2290 (5W-30) full synthetic oil (Peugeot Owner's Manual). Critical for turbo and chain longevity under high stress.
Emissions: Euro 6 certification applies to 2015-2016 models (VCA Type Approval #VCA/EMS/8890). 2017-2021 models are certified to Euro 6d-TEMP.
Power Ratings: Measured under SAE J1349 standards. Output is specific to the 308 GTi 300 variant (PSA Group TN-PET-007).

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.
Locate the engine code 'EP6FDTR' stamped on a flat machined surface on the front of the cylinder block, near the timing cover (PSA Group EM-5GP-01). The 8th digit of the VIN is 'G' for this specific 220kW/300PS variant. Visually, it can be identified by its red valve cover with '1.6 THP 300' branding, the Torsen limited-slip differential badge on the transmission, and the BorgWarner twin-scroll turbocharger. Critical differentiation from the 205 PS EP6CDT: The 5GP has a larger intercooler, a different exhaust manifold, and unique engine mounts. Service parts for the fuel system are specific to pre- and post-November 2017 builds (PSA SIB 9023C).
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.
