S54 3.3L Street Engine Rebuild

The CarBahn Autoworks S54 3.3L street engine rebuild is blueprinted and balanced, and features CP forged pistons and Carrillo forged connecting rods. We increase the bore by 1mm (which increases the displacement to 3320cc) and bump the compression from 11.5:1 to 12:1. A multi-layer steel (MLS) racing head gasket is also utilized.

Refer to the graphs below for the power results without catalytic converters on 100 octane race gas and using J607 (the typical aftermarket correction).

*Note – Core charges may apply. Contact us for details.

 

Steve Dinan has been building high performance and racing engines for BMW’s since 1977, winning 11 racing championships including 3 prototype championships and two 24 Hours of Daytona. The same engine shop that builds the racing engines also builds the street car engines; these talented engineers, machinists, and builders have built hundreds of engines from OEM street rebuilds to full-blown racing engines.
