Anyone familiar with cam shafts? ive been told that they give some extra HP, can anyone tell me what it really is and what it does, and what are its positives, and what are its negatives? thanks

the absolute only reason you would need new cams is if you went with a big turbo and had a built head. (ported and valvetrain upgrades.)

a camshaft rotates and opens the intake/exhaust valves in the head. aftermarket cams = longer duration and higher lift which makes more flow.

Worked over heads with cams on a stock turbo will increase spool up but there is only so much the stock turbo will flow to begin with so the above is kind of right, the most gains with heads and cams are coupled with an upgraded turbo.
