Now I think about it. I don't think the Supra needs to compete against the GTR nor next NSX.
The Supra was never as good or in the same level as those cars. It wasn't as advanced as the Skyline GTR nor was it nimble and sharp as the RX-7. It competed more against the 300ZX, were good cars but not in the same league.
They could bring it back with around 375hp and ~$40k to compete against the Z. Going up against Godzilla and NSX is unnecessary. The Supra name just doesn't have as much charisma.
