That was pretty much my plan, head to the junkyard and try to get two t3 turbos like the 280zx uses. I think most fords used the same A/R from what I have seen. Get a couple t3's, internal wastegate, low boost. Then when all of that is up and running you can always send in the t3's and upgrade to hybrid turbo if you crave more power. Start with bigger injectors and programmable EFI then all there is to upgrade is turbos, intercoolers, plumbing, wastegates
Oh it will happen, I will drive my own V8 240zTT. Like I say, my goal is in the 450hp and then after I get the car upgraded to handle that we will see. I could spend the next three to five years just to get to that point, but the knowledge gained will be worth the countless hours welding and fabbing.
I can't tell you how much I have learned in the last year and doing the L28ET swap only corrupted my mind.
