actually the b18c is designed to run n/a..... thats the whole point of high compression.
once you boost it, you will drop the compression to about 9.5:1 for about 12-15 psi. you're better off running an lsb18 with an aggressive cam.
If you're going to boost a b18c you're just better off going b18b block b18c head then boosting. But if you're going to do that you're better off going h22.
I know a couple people with boosted b18c's and they have them done up right.
