i have it on good knowledge that the max bhp a valver engine can go to is 197bhp(not forced induced in any way)
you would bore it out to a 2.2 litre and it would give you a 0-60 time of around 5.5 secs

but throwing money into the occasion could meen that the possibilties on engine conversion is endless

i like the origional question, cos the valver wins
