You aren't going to get much gain with a stock B16 with a header and intake. You'll have to convert to obd1 so you can get it tuned and then you can really start to see the gains. Nothing is cheap with going fast. If you do ls-vtec you'll still have to go obd1 and get a tunable ecu. Throw a gsr block under the b16 head, put some nice cams(like Skunk2 Pro 1's), valvetrain, a good header, good intake manifold with a bigger throttlebody, get it tuned and you should be fairly happy. But what I just said is probably at least $2000 unless you can find everything used or some good deals.

Really...I'd just convert to obd1 and turbo that bitch.. Run 7-8 psi and be happy.
