in the end of the day the escort cosworth was built as a rally car for the road, after its sucess in rallying in the 90's. Ford first built the large turbo model but as most buyers were business people, who bought them as company cars found the drive to have to much turbo lag as the car didnt do much before 4 thousand revs. this was due to the engine being detuned to 220bhp when it was sopost to run around 300. after this ford replaced it with the small turbo escort t25 which ran ford management rather that the weber management found on the big turbo models. In my opinion the later model drives like a fiesta turbo smooth off the mark where as the large turbo kicks a serious punch if modified. more like the series 1 escort. When i was looking to buy one i wanted an early large turbo model that i could modify to 400bhp, rather than buying a later small turbo model which had been messed around with ie management and turbo. As these cars are becoming more and more scarse i wanted originality. as i felt modifying a small turbo model would devalue the car more. In the end of the day mate it all depends what your after from the car if you want to go to sainsburys and take the kids out buy a small turbo model, if you want to spit flames and do some 4 wheel drifts and fast quarter mile time get a big one.!!!!
