Before the cossie i have now i had a 1998 s reg saloon st24 ,stunnin car ,group 16 insurance ,st200 is group 17 ,both are 2.5 v6 engines ,st200 has different cams and better flowing manifold ,basically ford did what u would normally do to achieve more power !!

St200s were very nice cars but are not worth the double askin price of a st24 ,the st24 is a lot of car for the money ,st24 bhp standard is 168bhp and the st200 is meant to be 200 but put them all on rollers and they achieve 195bhp ,they only go over once they have been played with even more ,chip etc and that can go on to 205 bhp maybe 210bhp but they are at there limits ,still very lively for a family saloon thats non blowered tho

I had my st24 chipped ,secondries properly cleaned and a few other little pieces and i achieved 180bhp ,which over 168 is pretty damn fine id say !!
