The Porsche MCX.TA is a 3,996 cc, twin‑turbocharged V8 petrol engine produced from 2023 to 2025. It features direct fuel injection, DOHC with variable valve timing (VarioCam Plus), and a dry‑sump lubrication system. In standard form it delivers 441–478 kW (600–650 PS) and 750–800 Nm of torque, engineered for ultra‑high‑performance applications with track‑focused durability and precision response.

All production years (2023–2025) meet full Euro 6d standards (VCA UK Type Approval #VCA/EMS/POR2025).
The Porsche MCX.TA is a 3,996 cc twin‑turbo V8 petrol engine engineered exclusively for the 992-generation 911 Turbo S (2023–2025). It integrates Bosch HDP7 direct injection with twin BorgWarner variable-geometry turbochargers featuring electric wastegates to deliver immediate torque and linear power delivery up to 7,200 rpm. Designed to meet Euro 6d emissions standards, it features advanced thermal management and GPF-enabled exhaust for clean, responsive operation.

The Porsche MCX.TA is used exclusively in the 992-generation 911 Turbo S platform with rear-mounted, longitudinal orientation and no external licensing. This engine features platform-specific titanium connecting rods, reinforced dry-sump oil pan, and active engine mounts for transaxle integration. From Q2 2024, Porsche introduced an updated HPFP with improved roller-follower metallurgy, creating part distinctions documented in service bulletins.
The MCX.TA's primary reliability risk is HPFP roller-follower wear in early builds, with elevated incidence in repeated track use without cooldown. Porsche internal quality data from 2024 indicated a measurable uptick in HPFP replacements before 40,000 km in track-driven vehicles, while UK DVSA statistics show negligible emissions-related MOT failures due to robust GPF control. Extended high-temperature operation without cooldown makes oil quality and fuel grade critical.
Analysis derived from Porsche technical bulletins (2023–2025) and UK DVSA failure statistics (2024–2025). 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
Yes—with disciplined maintenance. Early 2023 units have HPFP roller-follower concerns under repeated track use, but Q2 2024+ updates resolved this. With Porsche C4 0W-40 oil, RON 98 fuel, and strict adherence to cooldown protocols, the MCX.TA offers exceptional track-day durability and daily usability.
HPFP roller-follower wear in early builds, turbo bearing coking from hot shutdowns, GPF saturation from short urban trips, and minor rear main seal micro-leaks. All are documented in Porsche service bulletins and are largely preventable with proper driving habits and maintenance.
Exclusively the 2023–2025 911 (992) Turbo S and 911 Turbo S Exclusive Series. It is not used in Panamera, Cayenne, or non-S Turbo models. This is the highest-output V8 ever fitted to a production 911.
Yes. Stage 1 ECU remaps typically yield +40–60 kW safely with stock turbos and intercoolers. Higher stages require upgraded intercoolers, exhaust, and possibly HPFP support. HPFP condition must be verified before tuning, especially on pre-Q2-2024 units.
In combined driving, expect 12.5–14.0 L/100km (23–20 mpg UK). Highway cruising can drop to ~10.0 L/100km (28 mpg UK). Real-world figures vary significantly with driving style—track use can exceed 22 L/100km.
Yes. Like all modern Porsche DOHC engines, the MCX.TA is an interference design. Timing chain failure—though extremely rare—could cause piston-to-valve contact and catastrophic damage. The chain is engineered for life with proper oil changes.
Porsche specifies C4 0W-40 (or A40 5W-40) synthetic oil meeting Porsche approval standards. Use only Porsche-approved oils to ensure HPFP lubrication, turbo protection, and GPF compatibility. Change every 15,000 km or annually.
