First of all get the mod list on your profile up to date!

The right cam depends on what kind of turbo setup you are running...

It is basicly simple.

Sounds like you are asking about duration....

Duration is how long the valve is open.

Now there are 2 diffrent duration specs

Advatised The company that ginds the cams will give this, some use .002 lift others may use .006 or .010, on a say 272 duration cam, the company my start with the valve moving .004 lift to .004 before closing

then you have @.050.. this is an industry standard so you can compair all cams by this spec.
