its probertly right that its the laws there are the reson to that wee tune ower DOHC sierras, but just becourse that peoble in UK dont do it, that dont mean that it cant be done. if you try just a little bit to look inside the engiene. its having big(and i mean BIG) valves and other good stuff. and a std comp on 10,4:1 and i can doo manny 1000 of kilometers with that. but put a 4branch manifold and a chip and you hit 140bhp easy. and thats what i mean is big tuning potensial.. so what doo wee need more. vild cams and trottlebodys and a fullprogrameble ECU. try to put it together, i dont know your prises but try to call arrund

megasquirt + the wiring and sensors
trottlebodys
cams
4branch manifold.

and then see what you get. ofcourse the 2,3 scorpio/galaxy are better but its impossible to finde ower here. and its norman illigal to change the std top and blok. not to forget that the cosworth are a expensive car to have.

soo thats way i write what i doo, i mean that there are more in the dohc engine than you think in the UK. a lot more in fact.
