Personally I don't have broad experience with various turbo cams, but as a single anecdote I've been running my turbo '95 since 2009 with the stock cam and it works beautifully. I'm also not a max-horsepower person (I'm cheap) and until I'm ready to invest in an aftermarket engine block there's little point in upgrading cam / heads / etc. because the stock components can easily make 400+hp at the wheels at 10-11psi of boost and that's about all the stock block can safely take anyways. Unless that turbo cam and other upgrades are going into an aftermarket block, there is truly little point. Sure those parts could help make the same power with a little more efficiency, but as another 50hp and block-splitting territory is two clicks of the boost-controller away, I've never found a reason.
