S65 4.0L Racing Engine Rebuild with Carrillo rods
Connecting rod bearings and valve springs are major weak points in the S65’s design. In response, the CarBahn Autoworks S65 4.0L racing engine rebuild includes a reground crankshaft to facilitate a different rod bearing that is much more durable, plus stronger valve springs for prolonged periods of high RPM operation.
Internally, this engine is equipped with Carrillo racing rods with CARR bolts and centered-pin low friction forged pistons. We perform a valve job with new hydraulic lifters, timing chains, timing chain guides, timing chain tensioners, and all associated seals and gaskets.
Optionally, you may choose to further enhance performance with our very high lift and duration camshaft kit, specifically designed in accordance with SCCA GT2 and Trans TA3 rules. This camshaft kit also includes a conversion to solid lifters and high performance valve springs with titanium retainers.
This engine is excellent for BMW CCA, SCCA, Trans Am, or NASA club racing.
