A turbocharged V6 was never, ever considered as power for the ZR-1.

Way back in late 85, when what would become the ZR-1 was still in the early design stage, GM briefly considered a DOHC cylinder head conversion for the existing Gen 1 SBV8, but that's the only other engine configuration which was considered.

That said, keep in mind that before the idea of a Corvette worthy of the term "world-class sports car" (ie: more than just a "bigger" engine but a complete package of powertrain, chassis and brakes), in late-84/early-85, GM was looking for an engine capable of more more than 230-hp, a twin-turbo V6 was tested and quickly rejected.
