Calculate a Compression Ratio. B16A/B 75

Honda Compression Ratio Calculator



Calculate a Compression Ratio. By Clicking here you take full responsibility for determining a gasket for your engine.

This calculator is intended for use as an estimate of your compression only. Not all values are verified and may have varied results base on casting flaws, ect... You should measure your exact engine for a true result. Use at your own risk, we take no responsibility for incorrectly entered values. Double check your numbers and ours.

Make sure you always choose the same Series motor e.g. all D Series.
