Outlaw-4 Engine

The Emory-Rothsport Outlaw-4 is a very special creation. Its concept is simple, based on the 3.6-liter dry-sump engine architecture from the Type 964. We designed an original sand-cast 4-cylinder case that incorporates the best features from three different iterations of the venerable 911 engine. We then designed a proportionally shortened camshaft housing which is machined from 6061 billet. Our custom crankshaft and camshafts mate perfectly with Porsche OEM parts. The twin-plug engine design can be configured with distributor and carburetors or crank-fire/coil-on-plug and EFI with proprietary ITBs. The engine displaces from 2.4 to 2.6 liters depending on the specific configuration. We can also build turbocharged versions for special applications.

Giving a 356 “supercar” performance requires skill, preparation and the right components. Because there’s only so much horsepower that a stock 356 engine can reliably deliver, we chose to develop our own powerplant based on pure Porsche DNA.

Although there are other interpretations of a shortened 911 engine, ours was conceived on a clean sheet of paper with the engineering genius of Jeff Gamroth of Rothsport Racing. Jeff served as crew chief of Porsche’s factory GT racing team and has three decades of experience building street and race engines for a wide variety of applications.

The Emory-Rothsport  Outlaw-4 engine is only available as standard equipment in every Emory Outlaw, Special or RS we build.
