for example ... my D15B7 Anti-Vtec Single Banger project at the moment:

D16a6 cam - $40
Bisimoto Adjustable Cam Gear - $120
D16z6 Intake Manifold - $50
CAI of your choice - $100-$200
Headers of your choice - $200-$300

stock throttle body is fine for the job, give the car a good service using Honda FEO oil and an S2000 Oil filter, OEM Coolant, some new spark plugs etc and it should yeild some interesting results

might go for a bisimoto stage2 cam and pro valve springs instead of the d16a6 cam tho ... not sure yet - than again the D cam is so cheap i could probably try both lol
