A Rover V8 is shit end of

NA Yb is cool but you will pay for the luxury and tbh for what it costs you may as well have a 400hp turbo yb under the bonnet.

I only mentioned XE as it is relatively cheap to get 200hp from, yb is going to need all sorts but the rods and crank are well proven to take the power and revs.

Hayabusa would be tasty though
