If you are going to run one off of each manifold, and want lower rpm boost like that, I would say go with some type of t3/t4 hybrid... If you want to go the cheaper route I would say two 50trims would work well, or if you have the money some GT35R's would slay.... You could probably push over 600 easy with these setups....

It's not an exact science per say..... You can look at those compressor/turbine graphs all day and it will make you go crazy.
Since you are running two, you don't need to go nuts with the turbine A/R. A .63 or a .82 with the Vband option is what I would go with. The .63 will spool faster, but probably won't push the compressor as well as the .83 would.
As far as compressor, the GT35R is a 56 trim, .70 A/R as a standard... That's what makes it a GT35R
If it were me, I would go with the .63 turbine. If I were running a single turbo, I would run the .83
Have fun with the project, I would love to have the money to do a dual turbo setup!

would this be a bad turbo size for the 5.7? T-61 turbo T-6 exhaust flange with a 1.15 a/r

just about any v8 will flow enough exhaust to spoon a 1.0 + to full by 3500rpm
remember that you'll want to run catless to open up exhaust and coat your pipes in ceramic to keep the heat... EGT's are very important when running a Turbo setup... you'll want to monitor your A/F with an O2 WB. also remember that going catless you'll find yourself creaping another 2-4psi and since you'll only be running like 10 maybe... that could blow your **** out of this planet!!!

I currently have it running just tuning it right now. I have a wide band in it. It has no cat's in the exhaust. I did a whole custom stainless exhaust on it.

bulldog11267mad,
video would be even better... I'd LOVE to run a Turbo setup in MY06 DC.... the only "kit" i've seen is the TundraCharger by Motiva Performance.... I think I could get away for less than $5K for a complete setup with FMIC.
If you dont mind me asking... can you provide a breakdown on the cost for this project?
thanks
