You would probably be better off fitting a 1.8 silvertop zetec engine from a mk6 escort as they fit in really easy, fit some bike carbs and either a megajolt, nodiz or omex 200 ecu and away you go. Brake wise either Cosworth 2wd callipers for 15 inch wheels or st170 ones with 16 inch with discs to suit or spend lots of cash see the thread "St 170 breaks - what wheels?"
