too be honest. i dont know if the cosworth ecu and wireing will fit. but when you see the cosworth(bosch) injectores next to the std dohc then it looks like theay will fit down in the holes in the dohc top. but you need a new fuel line over the injektores. and then a new crank sensor. but if you boy a ecu from a 2WD, then it dont have eany knock sensores. and that woud be easyer to fit. but i relly dont know eany thing else. but it must be possible. you can fit it on at RST with KE-tronik standart. i cant se way not
