There are a ton of factors to think about when choosing a set of cams for a turbo vehicle.
Your best bet is to ask who ever is going to tune the car... Asking some idiots on a forum will get you no where.

I would need to know what size turbo your going to run, how much power your going to try to make, what turbo manifold your going to use to even give you an opinion on a good choice.

FYI: Stock cams work perfectly fine for most ls-t setups under 300 whp.
