What turbos should i use???

I'm building up a GM 3.8L Series II (L67) engine. I wanted to make it a twin turbo instead of using the stock blower.
I was wondering which 2 matching turbos to use.
-T25 from DSM
-TD04/05 from DSM/VR-4
-T3/4 from ????
Please let me know if these are also bad choices. I have been checking up on turbo maps to see if they work, but this is also my fist turbo engine build.
Thanks

I would probablly go with the TDO4/05 combo but a T25 with a T34 would probablly work well too.

T3/T4 Would be good for moderate power gains, IMO You should go with a Full T4, or a Full TD05

HP goals? Limits? When do you want power? What else are you doing to the engine? Fuel supply? Fuel and timign control?

yeah, what stall torque converter do you plan on using, I assume you want your turbos to spool with the TC stalled, right?
