LLY: Need some turbo help

[2005BlackLLY]

Hey guys! This is my first post here, but been trolling for a while. Been reading all I can about this but just can't seem to find my answer. I was in the process of putting my own "tubo kit" together, So far I have secured a T4 pedistal (turbonetics), A S366 downpipe (no idea on brand). I was wanting to run either a Batmo S366 or a S472/4. My goals are the mid 600hp range (built motor, with 40% over nozzles).

I was wondering how much of a difference I would feel in the truck with a t3 vs t4 S366?

I plan on using the truck for DD, and occasionally towing something under 5k (not a big deal I know). Any other turbo's I am overlooking to sit on the t4 pedistal? I want to try to do this as cheap as possible as I am on a tight budget.

Thanks so much!!!

And I have a Suncoast GMax5 trans, so thats not an issue either, along with a AD200 lift pump.

Give Trent (EPR), or one of the other vendors a call. I know that Trent has been using the T4 S366's.

All I can say is that my T3 S366 HTT spooled great and towed fantastic when I was using it as a single. I don't know about the larger frame or charger.
