The new Sachs clutch kit included a fresh pilot bearing, and the flywheel was also replaced.ĭocumentation includes invoices listing the parts and labor for the build, which totaled $17,300.Īn October 2016 dynamometer sheet indicates the engine produced 196 corrected horsepower at 5,500 rpm and 228 lb-ft of torque at 4,000 rpm. Two available 170-horsepower 4-cylinder engines combine capable power, efficiency, and impeccably smooth operation. The throttle linkage was re-plated, and a Bosch 009 distributor was installed along with Pertronix ignition.Ī 911 engine fan is paired with a red FAT shroud. Weber downdraft carburetors feature 130 main jets and 190 air jets. Finned aluminum valve covers are installed. FAT’s FC445 camshaft produces 0.495” lift with 302° of duration. Flat-type engines, whether its a flat-six engine or a flat-four, all feature opposing cylinders on each side of a central rotating crankshaft at a 180-degree angle. 48mm intake and 38mm exhaust valves were fitted with dual springs. The cylinder heads were ported, matched to their manifolds, and polished. The crankshaft, rods, pistons, and flywheel were balanced. Get to select flat 4 engine that matches your. The 105mm pistons and cylinders make 8.5:1 compression. Hop on to to engine assembly access wholesale flat 4 engine from some of the popular suppliers. An 82mm stroke crankshaft is installed, and new pushrods and Web lifters were also fitted. This Type 4 engine is now offered at no reserve in Del Mar, California with a dynamometer sheet and build invoices.Įngine case GC000326 was align bored, decked, and modified for windage. A new clutch was also installed, and the total build cost was $17,300. Induction is from Weber carburetors, and a 911 fan is paired with a red FAT shroud.

The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. This is due to its pistons designed to seamlessly work together, creating a perfect balance. A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. An 82mm stroke crankshaft is paired with 105mm pistons, increasing displacement by 42 percent. The center of gravity of the V4 engines is higher than the center of gravity of the flat 4-cylinder engines. Flat engines are known to be some of the smoothest engine systems the industry has seen. FAT Performance disassembled the donor engine and modified or replaced components with the intent of making a lot of torque for street use. The intention was to install this modified engine into a 912, however the seller has moved onto a different project. The seller provided a 2.0-liter Type 4 donor, which came from a Porsche 914. This air-cooled 2,840cc flat-four was built by FAT Performance in June 2016.
