Predicting performance - speed + acceleration (0-60)

[Davey]

My aim is a car that looks good and sounds good. I also want it to be fun to drive but good for a Sunday run out into Wales. Performance wise I'd like a 0-60 in the sub 4 second region, I'd like it to be a consummate cruiser that can puddle along at 2K or less without being unruly but will fly like sloppy dog dirt off a shiny shovel if you floor it, in any gear, from 2K upwards. Hence my engine choice.
