I am wondering what it will take to run 12's or better in the 1/4 mile. This would be in a Civic lets say biggest scenario a sedan. I was thinking B18 boosted but how much to get it to run that? I want it to be street legal drive to the track, race it, and drive home type of thing. The interior intact and not gutted at all. From looking at specs it looks like the main difference in B18's is the compression ratio which more compression is more power. But if you turbo it and change the pistons anyways then it wont matter. I could be very wrong though.
