What are you going to use twins for? Is it going to be a performance truck, or will it be for towing? What is good for towing, isn't the best performance combination.

So a 2.5 would be a 63-64mm turbo?? What's the size of the turbine?? What's the size of the exhaust housing?? What brand of turbo is it?? Holset?? Borg-Warner?? Need more info then just a 2.5 turbo.
