Man I can't thank you guys enough! Does 2.5" cold side and 3" hot side sound good? Im planning on twins so I won't have too much hot side piping.. The down pipe flange for the turbos is 3.5" and Ill try to go to 4" if I can make that fit..
Cam specs- Lift: .562" int./.562" exh
Duration: 211 deg int./230 deg exh. @ .050" lift
Turbos- 2 GT45 Compressor trim: 69, A/R: .66, Ind: 68.7, Exd: 97.8
Turbine trim: 92, A/R: 1.05, Ind: 87.4, Exd: 77
Downpipe: 3.5" v-band flange
Intake: 3.75" inlet, 2.25" outlet
2-50mm BOVs
2-40mm wastegates
Rear: Plan on building a ford 8.8 out of an explorer preferably but may settle for a ranger with 3.73 or 4.10 gears with 35 spline axles and a strange 3"x.083" seamless chromoly driveshaft with spicer weld ends and heavy duty U joints for 250.
Circle D high performance converter-still waiting to figure stall.. If I have to go to the pro single (900) or pro multi disk (1200) that would suck but y'all lemme know what you think.. Im hoping the high performance for 550 will do.
Any more info/advance/criticism is welcome. Y'all are the ****.

^no kidding those are big turbines for a twin 6.0. The 3" hot tubing is way overkill as well. If you rev it high enough it will make big power, but I will bet money it doesn't light those turbos up till 5000rpm, and it will be a frickin slug at any rpm below that.

Ok, that turbo you listed looks like the old Y2004K gt45 they have been pedaling for over a decade.. I have one of those pieces of crap I am going to use, maybe, only to get the car up & running but it will be tapped out quick.
One will meet your goal of 600HP. Two would be a tad laggy.
Has your goals changed?
Add: These would work a lot better & spool faster, especially if you get ported heads later.

gtfoxy thanks for the info. Would these be similar?

So you're saying this size would be better if I went with the twin setup? Depending on how much money I could save with going single I may go that route.. In such case what size should I be looking at?

Spool time in a .68 wouldn't be all that much & will help you make more top end power later. Those look like O-trim wheels.
If it were me, for twins, I would do what Jenna did & get these. http://www.cxracing.com/mm5/merchant...ory_Code=TRBT4

This is helping me out a bunch as well- so Thank you!
3pedals I've been reading your posts for years now....watching you get faster....pre-turbo(carb'd section).....anyway what do you think about 'gtfoxy's recommendations?
And what waste gates/ Bov's would be a good matchup for these turbos?
Thanks again to everybody for the input!!
