& with an N/A VK56 and the right mods, you are at around 750hp. Thats not including the supercharger which would be another 50-100 or so maybe

And then to spend all that money and keep the stock wheels with bald tires?
There wouldn't be any traction.

So my guess is stock, washer mod, and decals.

Here is a real VK56 Swapped 370z without a supercharger.
