hmmm the car wont go with high boost so 6 psi and maybe in future maxiumum 12 psi is my goal so what do u think ? is the t76 will be laggy turbo ?

 

I running a T66 but it is front mount and I'm running a 3200 stall. For a stock 5.3L I'd probably not go any higher than a 62-1.

 

You will end up with bigger turbo later so just get the 76 from the start.

Go with the smaller turbo, especially being rear-mount

 

agreed. larger turbo will spool slower, you need to look at the compressor map and make sure you are in the efficency island of the turbo. on a stock 5.3 a t62mm will probably be faster than a t76. instant spool>lag
