Well, I cant see the vid, but according to the vid title it was a Z51 C5 vette. Basically the base 350 hp engine with stiffer suspension. And if the Skyline is running 25 psi (even if it is a GTS), then its not a stock turbo and is easily outpowering the vette.

Sounds like the skyline really got owned in that case. Does it say in the vid if the vette is modded?
