Didn't know N/A was an option
What you say about the injector capacity doesn't make much sense. An injector flows what it flows, and when they are maxxed, they are 100% of the time open, sequential or batch.
Keep in mind that the zetecs have big choice of inlet manifolds and even teh old aluminum ones come in two different versions. The 1.8 105hp version will flow much less than the 1.8 130hp version. That's something you have not mentioned in your website.
It's a good website by the way.
Ram:
They really are not, although one design is more common than the others, but that's not the case here as we are talking side fed injectors.
