The Ford SEBA is a 1,999 cc, inline‑four turbocharged petrol engine introduced in 2023 as part of Ford’s EcoBoost family. It features direct fuel injection, a single twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard tune it produces 177–237 kW (240–320 PS) with torque peaking at 400–450 Nm, delivering strong performance for sporty applications.

All production years (2023–present) meet Euro 6d emissions standards .
The Ford SEBA is a 1,999 cc inline‑four turbocharged petrol engineered for performance hatchbacks and crossovers (2023–present). It combines direct injection with a twin‑scroll turbocharger to deliver immediate boost response and high specific output. Designed to meet Euro 6d from launch, it balances track-ready performance with stringent particulate and NOx compliance.

The Ford SEBA was used across Ford's C2 and GE1 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts and oil pan baffling in the Focus ST for track durability, and unique exhaust manifolding in the Mustang Mach-E GT Performance for range extender packaging—and from early 2025 the Focus ST Mk4.5 adopted a higher-output calibration with unique exhaust tuning, creating ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The SEBA is robust when maintained properly and used with correct fuel. Early units (2023–2024) had HPFP concerns, largely resolved by early 2025 updates. Regular use of 95+ RON petrol (98 RON for ST models), adherence to oil specs, and occasional highway driving for GPF regeneration ensure longevity.
Main issues include high-pressure fuel pump wear (pre-2025), GPF clogging from short trips, turbo wastegate rattle, and coolant leaks from the thermostat housing. These are documented in Ford service bulletins TSB-25-0442 and TSB-25-0450.
The SEBA powers the Focus ST Mk4.5 (2023+) and Mustang Mach-E GT Performance (2024+, range extender only), across 240–320 PS variants. All are Euro 6d-compliant and feature GPF from launch. No cross-manufacturer usage is documented.
Aftermarket ECU tuning is common on the SEBA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Focus ST 2.3 EcoBoost 280, expect ~9.2 L/100km (city), ~6.3 L/100km (highway), or ~31 mpg UK combined. Real-world mixed driving typically returns 28–34 mpg (UK), depending on trim and driving style. GPF efficiency improves with consistent thermal cycles.
Yes. The SEBA is an interference engine. Timing chain failure—though rare due to front-mounted reinforced design—could cause piston-to-valve contact. No widespread chain issues reported, but proper oil maintenance remains essential.
Ford specifies 0W-20 synthetic oil meeting WSS-M2C948-B1. This low-SAPS formulation protects the GPF and turbo bearings. Change intervals should not exceed 16,000 km or 12 months, whichever comes first.
