Will you have enough fuel to spool two turbos indavidualy? What are you running for a pump just the db2?

I probably wouldn't waste your time.

I think it's a completely do-able project and would be fun. However I think you can't just take any two turbos you happen to find and hope it works. You may have to change turbine housings or something to reduce volume since you're basically only running 4cyls into each turbo. I think much smaller turbos are in order to make this work. But it's a good idea and might just turn out great. Go find some expert help on turbo selection. Personally I'd keep the remainder of the engine stock and just focus on the turbocharging. Adjust fuel after for to match the new turbos. Don't try to make a bunch of "smoke". Adjust it correctly.

The two turbos you have are too big. This has been done on a 6.5, but I think the turbos used on that were off of a small gas motor. If I remember they were subaru turbos. So the turbos were off about 2.5L motors? There are still probably pictures somewhere.

6.5 turbos should work just fine. It's been done on a 6.5 before an it should work for your project.

A pair of traditional T3-45 or T3-50 turbos would be best and very cost effective.

Something I've contemplated trying someday would be to run two pumps in parallel. There's a guy who does tractor pulls with a duramax-powered massey that used to have a 6.2L in it. He ran twin injection pumps:
http://www.thedieselpage.com/readers/kolkman.htm
I don't know what the max flow rate of the stock injectors flow, but they'd be your limiting factor for power after the pump and turbos were taken care of. I don't know if some injectors off the old cat idis would work, but I've also thought about trying that later... I have a lot of fun/crazy ideas for these engines because they're underdogs.
Anyways, if you don't like the twin pump idea, you could run one of the moose pumps that the oilburner guys like so much. They still won't support the air of twin turbos though. Fuel is the biggest limiting factor on these engines assuming you stud the heads (which I'm sure you've already done or are planning on doing... I hope...).

The static compression ratio of the engine is too high. It might live for a little while if you run external wastegates.

Seen a guy run twins (one on each manifold) on a 6.2, pretty sure he used turbos off of a 300d Mercedes, heard it ran good, then he kinda fell off the map. I figured he broke the crank about 2 weeks in. IH engine would probably handle it a lot better.

Why run a moose pump when you can get better pumps that flow twice as much fuel...
Fuel is the limting factor right now, and there is no reason for twins when all we have is 180cc's to work with... A single will burn all of that fuel.
2.5-2.7whp/cc is the dyno'd range for an IDI... so provided we can get an efficient setup, we could get close to 500whp, but I doubt we will make the number itself...
As far as injectors go, as of now they arent a restriction... They have an Orifice size 3 times that of a 5x.012 injector... With a pintle tip removed, they can flow more fuel than we can deliver.
