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…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
Yes—with disciplined maintenance. Early units (2021–2023) have HPFP thermal wear risks under track use, but post-2023 updates resolved this. With Porsche C4 0W-40 oil, RON 98 fuel, and adherence to cooldown protocols, the MCV.DA offers exceptional longevity and track-day readiness.
HPFP plunger seizure in early builds, turbo bearing coking from hot shutdowns, GPF saturation from short urban trips, and minor rear main seal weep. All are documented in Porsche service bulletins and are largely preventable with proper driving habits and maintenance.
Exclusively the 2021–2025 911 (992) Turbo and 911 Turbo S. It is not used in Panamera, Cayenne, or any non-Turbo 911 models. This is Porsche’s first V8 application in the 911 lineup, replacing the traditional flat-six in high-output Turbo variants.
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-2023 units.
In combined driving, expect 12.0–13.5 L/100km (24–21 mpg UK). Highway cruising can drop to ~9.5 L/100km (30 mpg UK). Real-world figures vary significantly with driving style—track use can exceed 20 L/100km.
Yes. Like all modern Porsche DOHC engines, the MCV.DA 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.
