Power? Not a lot, I suspect, as it uses a Honda Type R throttle body. No mention of an LSD. No mention of upgraded brakes.
It's a car to impress at car shows, not to drive, and as a labour of love, a car to show, and an example of what can be done, it looks very very good.
As a car to drive, why bother? Buy an E55K, which I'm certain will kill it stone dead as standard, take it to MSL, give them carte blanche and £30K; now that would be a weapon...
