Cool looking setup for sure. I wonder if the V6 +turbo + I/C + plumbing would be close to the weight of an L98 or the ehavier LT5?

Could V8 manifolds be swapped out to be used in a V8 application?

It would be interesting to get a readout of that PROM.

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.

SVI did a prototype TT Corvette(v8) in 85 or 86. GM used this prototype to work with Callaway in putting the TT into production.

Before landing on the LT-5 vs a TT setup, GM did build a series of TT cars....Motor trend noted that they ran a test with a Lambo running at 120, as it passed one of the TT prototypes(sitting still) ...Jim Engles punched it....at the end of the mile the TT vette has passed the lambo at 180+....
