Thought i might chime in on this a large cam does not mean it wont work....its about combination think of the characteristics of the cam N/a the overlap from a wider lobe seperation might not work well on a small turbo designed with moderate airflow at low rpm, but what it can do is aid in spooling of larger turbos buy allowing unburnt fuel to burn in the exhaust manifold like a secondary combustion chamber,as events get quicker the amount lost through overlap is slowed and the larger turbo can easly handle it....problem is this kind of set up moves everything away from being a daily to more a racer style setup as it has reduced torque down low until everything comes on song then its huge and late in the rpm
A big cam and small turbo wont work because the loss in boost pressure will see the turbo working harder to make upfor it, generating more heat as it moves further out of its efficiency meaning less power,the motor wont see its full potential because the turbo wont allow it rev
So the short if your cam isnt overly wild and your turbo isnt too tiny it probably will work fine just higher in the rpm range...
