I was looking at the Specs for the new Kia Stinger. 3.3 Ltr V6 TT, 365 HP, 376 lb-ft torque. (for Gt1 or GT2 option)
Tis is not in the same category as the Z but Infiniti Q and Acura, watch out.
This TYPE of engine would be a MONSTER in the Z. Yes, You can do better with Aftermarket, but you got to pay and do the work.
At a price point LESS or close to the Z, this would be a bargain.
Again, a different class and it's KIA, but engine wise, it would be an easy build on the VQ engine.
