Hi all going looking at buying a sapph this week, the one i have in mind has a late spec escort cosworth engine running coil pack, is this good or not? is there an advantage to it? also he mentioned air injectors, don't mean to sound thick but what are these air injectors? i never owned a cosworth before so don't know much about them, also where abouts should i look for rust? the car is suppost to be running near 400bhp

 

Mate if you don't know what all this stuff is, you're not going to know if it's working properly or not, there could be an enormous bill waiting.
