Hi mate i have own a lot of diffrent car V10 BMW M5, Evo 6, AMG Mercedes, but they are still not as fun to drive as am Escort cosworth. I bought a small turbo model as in my option the are the best engines they have a better head and better inlet manifold but with the Ford EEC engine management the are restricted to about 300bhp. There are a few different ways to get more power you could change out the ECU for an aftermarket one or go down the route I have and change the ECU and wiring loom for a Big turbo model both are relatively easy to do if you have some mechanical skills, mine should be running about 400bhp after the ECU change out. Once the ECU and engine loom have been changed the only limiting factor for big power is you pocket. If I was you I would buy a standard one and modify it yourself. I have owned my now for three years I have had a couple of minor problem but other than that it has been a great car to own.
