do you think is wise to throw on Twin T70's on the 5.3 for now if I plan on moving up to a 402 later?? 
5.3l twin turbo sizing
5.3l twin turbo sizing I'm getting ready to start a new project and am wondering what size turbos would work well for a relatively fast spool time - say around 2500-3000 rpm.
The setup is:
5.3l with 241 heads for a CR ratio of about 8.8:1
Front mount setup using C6 manifolds
Six speed and 4.11 rear gear
60lb injectors
Z06 cam
I am thinking this setup should be able to support around 15 psi on 91 pump gas safely - open to thoughts here as well.
What size turbos I should go with for this?

No I do not have model numbers, I am sure FI can set you up with something though.
Twin 70s will take a good bit to get lit up on a stockish 5.3l even with the small turbine housing. They will work but will not have a great feel on the street, you will be wating for boost. They would be great on a 402 though!
