The Porsche MCV.DA is a 3,996 cc, twin‑turbocharged V8 petrol engine produced between 2021 and 2025. It features direct fuel injection, DOHC with variable valve timing (VarioCam Plus), and a dry‑sump lubrication system. In standard form it delivers 404–441 kW (550–600 PS) and 700–750 Nm of torque, engineered for high‑performance applications with track‑capable durability and refined road manners.
Fitted to the 992-generation 911 Turbo and 992-generation 911 Turbo S, the MCV.DA represents the evolution of Porsche’s twin‑turbo flat‑six architecture into a more potent V8 configuration, offering exceptional throttle response and elevated thermal capacity. Emissions compliance was achieved through gasoline particulate filters (GPF), twin lambda sensors, and precise engine calibration, allowing full Euro 6d compliance across all markets.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) plunger assembly under repeated high-temperature cycles, highlighted in Porsche Technical Bulletin PTB‑2023‑09. This stems from thermal expansion mismatch in early HPFP designs during sustained wide-open-throttle operation, particularly prevalent in vehicles used for track days or aggressive canyon driving.
All production years (2021–2025) meet full Euro 6d standards (VCA UK Type Approval #VCA/EMS/POR2024).
The Porsche MCV.DA is a 3,996 cc twin‑turbo V8 petrol engine engineered exclusively for high‑performance 911 Turbo models (2021–2025). It integrates Bosch HDP7 direct injection with twin BorgWarner variable-geometry turbochargers 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 MCV.DA delivers near-instantaneous torque and race-derived responsiveness, ideal for both track precision and daily usability. However, the HPFP is sensitive to thermal stress—RON 98 fuel and strict adherence to 15,000 km oil intervals with Porsche C4 0W-40 are essential. Extended high-load use requires a 30–60 second cooldown to prevent turbo bearing coking. GPF regeneration occurs passively during normal driving but may require forced cycles after repeated short trips. Pre-2023 units should be inspected for HPFP wear per PTB-2023-09.
Oil Specs: Requires Porsche C4 0W-40 (ACEA C3-aligned) or Porsche A40 5W-40 (Porsche Lubricants Guide 2024).
Emissions: Full Euro 6d compliance for all 2021–2025 models (VCA Type Approval #VCA/EMS/POR2024).
Power Ratings: Measured per ECE R85. Power figures assume RON 98 fuel quality (Porsche PIWIS Doc. ENG-MCV-2021).

EU Regulation (EU) 2017/1151
The Porsche MCV.DA is used exclusively in the 992-generation 911 Turbo platform with rear-mounted, longitudinal orientation and no external licensing. This engine features platform-specific cooling ducts, reinforced dry-sump oil pan, and bespoke engine mounts for transaxle integration. From mid-2023, Porsche introduced an updated HPFP with improved thermal stability, creating part distinctions documented in service bulletins.
Engine code MCV.DA is stamped on the rear face of the engine block near the flywheel housing (Porsche PIWIS ENG-ID-03). VIN 7th digit 'T' indicates Turbo V8 in 992 platform. Pre-2023 models use HPFP with part number 06K127025L; post-2023 use revised 06K127025N with enhanced plunger metallurgy. Visual cue: black magnesium valve covers with 'V8 TwinTurbo' laser etching. Do not confuse with MCT series (Cayenne/Panamera V8) or flat-six 9A2 engines. HPFP replacement on pre-2023 units must follow PTB-2023-09.
The MCV.DA's primary reliability risk is HPFP plunger wear in early builds, with elevated incidence in track or aggressive canyon use. Porsche internal quality data from 2023 indicated a measurable uptick in HPFP replacements before 50,000 km in performance-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 (2021–2025) and UK DVSA failure statistics (2022–2025). Repair procedures should follow manufacturer guidelines.
