Korman V-12 Engines
New Korman V12 Engine Program
Our previously advertised 5.6 liter BMW V12 motors have been discontinued as the parts we used from Germany are no longer in production. To continue our high performance V12 engines we have had larger stroke custom crankshafts made. The engine is capable of 6 liters and as the cost is the same for a crank to produce 6 liters as it would be for 5.6 our new program is for 6 liter engines in a ‘stock’, or Stage 1, 2, or 3 configuration. The bore is increased from 84mm to 86 mm and the stroke from 75 to 86.
The Euro Dollar has climbed so much against the dollar that our new 6 liter motors cost less than the previous 5.6 engines. Our base engine parts, water pump, oil pump, bearings, etc are still BMW original parts. The aluminum blocks cannot be honed or bored as this destroys the hardened coating and there is no facility with the capability to re-coat these blocks outside of Germany. We install high quality steel sleeves which enable us to use conventional type rings and pistons. Where we use American products, crankshaft, pistons, and connecting rods, they are all race quality, precision parts. For more than forty years our philosophy for our Korman street performance engines is to design and build them to out perform and outlast the factory original parts. We have won many championships with our race engines but we do not believe in ‘extreme’ solutions for daily driving.
All stock BMW components plus sleeved block to 86mm, 86mm custom crankshaft, forged 10:1 pistons, special head gaskets, custom computer chips. Includes tune-up and service parts such as ignition wire sets, distributors caps and rotors, thermostat, air intake boots, serpentine belt, and spark plugs, etc.
