Default Which large frame turbo for a 5.3?

Decided to go another direction for my build, was going with a T70/LS6 cam. My friend (tripblackls1) has a MS3 and a Holset HX 55 in his 4.8 with a M6 4.10s and loves it so i want to do something similar. Im going to run the Brutespeed FI cam (232/240 .595/.608 115), 9:1 compression, 3.73s, M6. I have 3 turbos in mind, the first being the HX 55, second being the S372, and third being the S475. Not looking to spin to the moon, so which of these would work and is there a better large frame choice?

How much power at the crank and boost are you going to run and what is your max rpm? An ms3 is not a turbo cam lol.

For a manual street car I'd stay on the smaller side. But that's just me. Unless you up the CR and run E85.

We use the BW400-75 T4.....which some call the BW375. Great turbo, spools good and will make 800rwhp no problem on that size motor.

Price? Not looking to spend a fortune. And i know the MS3 is not a turbo cam, but on a 113 its not horrible. I said it because the specs arent far off from the Brutespeed cam

Would an s366 extended tip work?
