Integrating more potent powerplants from different makers into personal project vehicles isn’t groundbreaking, but installing an Audi 2.7T engine behind the rear wheels of a Porsche 911 might be quite unprecedented. Renn27 is currently executing this innovative swap, providing a shortcut to assembling a Porsche 911 Turbo potentially at a remarkably lower cost compared to acquiring a factory-made variant.
This firm extends assistance and swap components to facilitate this conversion, with enticing advantages if the vehicle’s engine bay belongs to a 996-model 911.
The rationale behind this choice is that the Mezger-equipped 996 911 Turbo currently commands a substantial sum, especially those in a predominantly well-maintained state. Conversely, the 996 Carrera 2 or 4 is more abundant and significantly more affordable. In reality, finding one in good condition for about $20,000 is feasible—this is also valid for auction estimates.
This conversion provides an opportunity to rectify some of the flaws in the 996’s design. The M96 powerplant at the rear may be decent, yet it can manifest expensive issues, particularly if not adequately maintained, including the notorious intermediate shaft bearing quandary.

The Audi 2.7TT engine holds significance for those well-versed in the automotive industry; it played a key role in elevating the B5 S4 to legendary status among enthusiasts. This V6 powerhouse might be slightly complex to service, but conducting a comprehensive engine-out maintenance with fresh gaskets, timing elements, and minor enhancements for reliability can transform it into a robust performer. Consistently adhering to periodic fluid changes is crucial.
Renn27’s methodology—due to the engine swap—simplifies all maintenance tasks and even includes transitioning to a single-turbo configuration and air-to-water intercooler setup, likely to address spatial constraints. The organization asserts that this specific configuration can endure 100,000 miles post-refurbishment and is capable of generating around 500 horsepower reliably. Integrating it with Porsche’s electronic systems is straightforward as both the B5 S4 and 996 911 employ Bosch Me7 engine management. Partnering with 27Swap streamlines the collaboration process.
Delve into Renn27’s video content available on their YouTube channel that comprehensively explores all facets of this project. Both companies’ websites and Facebook and Instagram accounts contain a wealth of information, including additional opportunities for the 2.7 engine swap.
