DVYA 4.0 – Porsche 911 GT3 RS (992) Head Gasket Keychain

This stainless-steel head gasket keychain celebrates the Porsche DVYA: the naturally aspirated 4.0-litre flat-six fitted to the 992-generation 911 GT3 RS and 911 S/T. It is a rear-mounted, high-revving 3,996 cc boxer engine producing 525 PS and reaching 9,000 rpm.

• Cylinder count: Six cylinders in horizontally opposed layout.

• Displacement: 3,996 cc / 4.0 litres.

• Production period: 2022–2024 in the cited 992 GT3 RS application; it was also used in the 2023-on 911 S/T.

Porsche’s official GT3 RS technical specification identifies a six-cylinder naturally aspirated boxer engine with a gasoline particulate filter, 3,996 cc capacity and four valves per cylinder. Parts-catalogue fitment information lists DVYA and DVZA for the 992 GT3 RS, so engine code must be confirmed from the vehicle’s data label or documentation when identifying a particular car.

Vehicle Compatibility Matrix

The DVYA appears in vehicle fitment data alongside the DVZA code for the 992 GT3 RS and 911 S/T. The source material confirms shared capacity and output but does not establish that DVYA and DVZA are identical in every internal part or market calibration; Gasket Keys copy should therefore describe DVYA specifically and avoid claiming universal service-gasket interchangeability.

Why This Engine Matters

The DVYA represents Porsche’s high-revving, naturally aspirated GT-car approach at a time when turbocharging dominates much of the 911 range. It produces 525 PS at 8,500 rpm, 465 Nm at 6,300 rpm and runs to a 9,000 rpm maximum engine speed.

In the 992 GT3 RS, Porsche pairs this engine with a short-ratio seven-speed PDK transmission and rear-wheel drive. In the limited-production 911 S/T, the same 525 PS, 4.0-litre flat-six is paired with a six-speed manual transmission, giving it particular significance among modern Porsche enthusiasts.

Technical Specifications

The above engine data is taken from Porsche’s official 911 GT3 RS technical specification. The 911 S/T uses the same stated 4.0-litre, 525 PS and 465 Nm output, but its manual-transmission installation differs from the GT3 RS PDK application.
