ENGINE BUILDS

PORSCHE AIRCOOLED ENGINE REBUILDS AND PERFORMANCE BUILDS 

 

We at Göritz SIXFIX LLC specialize in building Porsche Aircooled Engines, specifically the 911 from the 1964 901 through 1998 993 M64 including Turbo engines, as well as all derived engines from the former mentioned models like 906 and 935. Furthermore we are also offering the build of 616 engines from the 356 or 912.

PERFORMANCE PACKAGES: Apart from stock rebuilds we offer one to three proven and reliable performance packages per 911 engine generation. Please read below about each generation’s specific packages.

ONE-OFF PERFORMANCE BUILDS: If you are required to meet certain specifications or want something crazy, we are happy to build those upon customer's request as well.

Magnesium Engines

STOCK: Bring it back to its original Glory.

PERFORMANCE: Magnesium Engines require a gentle touch, due to what the magnesium cases can handle at this point in it's lifespan. One of our most popular upgrades on the 2.4 and early engine is to bore the cylinders to 85mm, Custom Pistons, Performance Camshafts and using the 70.4mm Crankshaft to create a true 2.4 liter engine with almost the power of the Stock Carrera RS.

Early 911

Early 911 Engines are 2.0 Sandcast Aluminum Case based Engines, in our view. We love them because opposite to the later magnesium case engine they can take serious performance upgrades

Stock: Stock rebuild

PERFORMANCE 1: These Engines are perfect to build 2.5 Short or Long Stroke Twin Plug Engines with ported heads, performance camshafts, retrofitted piston oil squiretrs and more. The ultimate sub 3.0 Porsche Hotrod Motor.

356/912 aka 616

BIG BORE: At a minimum when rebuilding a 616 we recommend the conversion to a 1720cc and a mild camshaft upgrade.

PERFORMANCE 1: 1.9 Bore-In with a performance camshaft and Weber Carburetor Conversion.

PERFORMANCE 2: Willhoit 1950cc Premium Stroker

PERFORMANCE 3: Willhoit WR 2.2
