Default well sold the 78mm...looking for a new turbo *need advice*

ok guys i'm sure everyone is tired of seeing all my questions
but i just want to do this thing right

408/4l80e
6.0L iron block and #317 heads
gonna get an isky cam
4"callies crank
eagle H-beam rods
wiseco -20cc pistons
all going into a 2000 full size rcsb w/ manual windows/locks

i am looking for upper 700's on pump gas (wouldn't hurt for more...lol)
this will be a street truck so i would like it to pull really good from 2000-2500 to 6000-6500rpm
a t6 is not out of the question i have not built the kit yet but it will have a 4" dp

I reccomended a reasonable price turbo that will efficiently flow the air you need to reach your goal.Don't worry about hp rating cause that is subjective.You should try learning to read compressor maps.Find out what the turbo flows lbs/min. that is more important than hp ratings.

Btw:Twins are going to put you out of budget fast.
