actually they arent too bad.. and getting performance parts on them are quite easy to tell you the truth....
the engine is easily tunable to 200bhp retaining basically stock running gear...
just a change of cams, exhaust, intake manifold, ecu tune and filter.. and shazam....
add throttle bodies and it goes up alot further..
the engine in the ARC rally fiesta is the same engine from the XR4. a 2ltr Duratec, it has just been tuned thats all....
