low lobe separation angle (LSA), which means low overlap as well as they have low duration as high duration and low LSA still creates more overlap. the design is around driveability and midrange power, as is the turbo that comes with it.

it's not that the stock cams are magical, and it's not that aftermarket cams are either. it's just that until you get rid of your biggest restriction in airflow and power which is the itty bitty turbo, there's no point in putting cams in there that are gonna still be restricted by the output of this same itty bitty turbo.

upgrade the turbo and do all the other supporting mods, THEEEN tweak the power band with some cams if you want to.

cams definately have their place and use in the scheme of things, there's just a lot of other more important things that limit the engines power output that should be dealt with before the cams need to be.

cams are more like the final touch to the engine build. the icing on the cake if you will. the proper cams will compliment the already thoughtfully upgraded turbo system.

if it's between upgrading the stock turbo versus the stock cams....deal with your weakest link first.

that's where my emphasis is.
