Stage 6 Audi S4 B5 History This B5 was built by a Nor Cal Audi club member Marin S4 in the forum. Those long time members will remember this car frequently referred to in the forums. Like the gold standard of advanced B5 engine building. It was considered by many in the Nor Cal Audi club to be one of the most desirable S4s in California. All essential parts of the motor are genuine B5 RS4 parts right down to throttle body, KO4s and camshafts. The Brakes and Suspension and other misc improvements. This car has been my favorite passion project and has improved every year I have owned it. You will not find another B5 built this completely. Engine , Drivetrain, Brakes and Suspension all upgraded completely and correctly. The engine alone is worth the asking price. Power and Handling This car must be driven to appreciate. It is truly the fastest best handling car I have ever driven. I am 60 years old and have owned and driven a lot of high performance cars.
