EZ30R sleeved and bored out (forged internals & long rod too), built heads, GT47R, intke manifold (exhaust duh) and then all the supporting mods (fuel pumpS, injectors, rails, etc)....NOS to help make it easier
drivetrain should be interesting...
50k with hook ups and doing the work himself = possible
50k paying someone to do it = not very likely (R&D isn't cheap)
