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.
