On a stock B18A bottom end how much compression will I have when I install a B16 head from a 99 Civic Si? Will I keep the stock LS 9.2 compression or does the Vtec head have smaller combustion chambers??
The compression will go up. It’ll be 9.8:1.
The combustion chamber is slightly smaller
i calculate it slightly lower 9.55:1 compression based off
stock parts specs
