Good, turbo it! It's the cheapest way to go.

A K&N might give ya 2hp. The stock intake IS in fact a cold air intake. Well
it's supposed to be, maybe some of that stuff is missing from your car.

Maybe another 3hp on the stock motor. I don't think a cold air intake and
exhaust are going to give you much more than noise.
I had less in my CIS turbo system than an exhaust system costs and it ran
15.5 at 85 in the quarter mile....(stock was 17.4 at 78 or something)
If you really want more power naturally aspirated, you're getting into cams,
headwork, higher compression. All of these increase in cost exponentially.
Bolt on a K24 at 6psi and you're done with it. Gobs of torque, and lots more
HP too.
