Default need help with turbo selection

I'm pretty sure i'll either be purchasing either a Garrett ball bearing or a Turbonetics Turbo soon only problem is i have no idea how to size one up for a truck...

vehicle specifics are:
05' nissan titan 5.6L with DOHC
340cu.in
engine has a Forged crank, and 6 bolt main.. stock compression is 9.8:1
Jim wolf technologies camshaft specs:
256deg .430"lift (compare to stock at 232deg. .346"lift) 219.5deg@.050"lift

IPT 3400 stall converter, IPT Upgraded valvebody, IPT "Bullet Proof tranny", Custom built Traction bars with double heims on each bar for preload, Flex-A-Lite Electric Fans, Jim wolf Technologies S-2 Camshafts, 07' Nissan Titan Intake manifold, AEM bruteforce CAI, NGK 1 step colder iridium plugs, Poweraid throttle body spacer, Stillen longtube headers, Stillen diff cover, JBA Evol Catback exhaust, 2.5" Dynatech powercat catalytic converters, Detroit trutrac LSD,
I'm planning on doing a single medium single turbo (capable of 700+hp) under the cab of my truck.. I will not beable to use full potential of the turbo for another year or so till i get forged low compression pistons, c-rods, and rings, but for now i wanna get the set up done and just keep the boost low till i can really take full advantage of my $6,000 dollar built tranny from IPT
I'm mainly into drag racing with friends and going into boost on a daily occurence will be minimal but i'd still like it to be responsive..

wanting to get around 465rwhp 500+tq right now till i can get the funds for a engine builder..

hehe stay ahead?? he still has a ways to go.. im running high 12's n/a... with boost i want deep 12's or high 11's with trap speeds of 115mph.. dont think it's asking too much of a motor that is capable of making 500hp boosted with the right tune

You could do that with a 70..... a nice BB 76mm would spool fairly quick and move a bit more air for you

haha oh I meant as far as getting a boosted truck first not necessarily the times that are being run now. Either way its going to be a big step forward for titans everywhere.. trapping 113-115 is fun

mychael is boosted now but tranny is going into limp mode i kept telling him he needs a built tranny and uprev to take full advantage of the turbo cause thier is "TONS" of restrictions in the stock ecu that have to be removed to make it even worthwhile...

of course i'll use uprev.. already have thier end user tuner package on a laptop.. so i can go anywhere to get tuned..

the hardest thing to tune for my truck will be the injector pulse for the larger injectors i'll be using, but i think thier is a a scale that is inside the tuner software and you just enter thier impedence and scale them to what % is needed for the hp you will be making..

what size injectors are you going to be running once you decide the size of the turbo?

thinking about the jim wolf 555cc/hr injectors on thier site it says that 6 of them are capable of handling 600hp, so i figure 8 would handle 700hp.. i might call jim wolf tommrow and see if they can help me with turbo sizing..
