Um... read the article, sparky. :eh:

They're at the planning stage now.
They've been considering the idea of a V8, off and on, for many years.

We are a long ways away from any specifics on CR, displacement, etc.
That said, I would expect about 4 liters of displacement and 4 valve/cylinder DOHC VTEC heads.

Who knows what kind of output you'll get, but the whole point of building a new motor would be to beat Nissan and Toyota at their own game.
