How Does Aftermarket Cam Gears Increase Hp?

[lingeringsoul]

Can someone explain to me how they increase? how it works? All I know is that it looks like a cog and I'm not even sure where it goes. Any info would be great

Is it possible to do it yourself rather than take it to a shop?

hey, a standard rb20det cam has 248deg intake duration and 7.8mm lift, if you have an aftermarket cam ex. tomei which has a 260deg with 9.15mm lift for every time the valve open its open for a longer duration with more lift so incur there is more air forced into the cylinder every compression stroke of the engine and the exhaust cam has the same effect but lets more air out of the chamber. hope that helps.

sorry dude thought u meant cams,

I think he is talking about adjustable cam gears

Take it to a shop unless you are familiar with the process of removing and replacing your timing belt.
