After trying ALOT of cams and turbos on the same basic engine, I came up with some very basic self tested rules:
The smaller the turbine, the smaller and wider you want the cam.
Pump gas likes less lsa at higher boost levels.
Race gas likes more lsa (seems backward doesn't it?)
A free flowing turbine/wheel combo will like a cam closer to that of a n/a engine, don't be afraid of a 260+ cam.
