I've fitted the 1.8 16v zetec into my ka. I've had no end of problems fitting different things.
I done away with everthing, i made my own bracket for the alernator and measured up the length of belt and got it from my local car store. Theres not a lot of room, especially when you've got a escort raditor in.
I've got two pic's but havent managed to upload them yet, i've more to take, roll cage, uprated suspension. Oh yeah mines gonna be a sprint/hill climb car, up rate to carbs later on.
