I'm about to put a b18c1 into my 93 ls, but I wanted to do some internal engine work to the new motor before installing it. I dont plan on ever turbo-ing it, so raising the compression ratio sounds like a plan. The GSR starts at 10, and the tegra type R has 10.6. My friend was telling me about people who have gone to 12... I don't know enough about getting thicker pistons to know what all there is to consider. Should I stop at the tegra Type R's 10.6, or should I go higher? I've also heard that the civic type R's ratio is higher than the integras, but I dunno what it is. What do you think?
