I feel these are way too big for a n/a engine. My objective here is to go to a 460cc injector. Hi Mark, As Al mentioned, you may not be in bad shape with the 550's. I recently changed from 550's to 460's on a NA 13B, and I couldn't see any difference in idle. Mixtures only had to be slightly adjusted anywhere along the range, so I just don't think there's that much difference between the two. It's been suggested before that Mazda rated some of their injectors at "standard" 3 bar pressure, and some at their lower fuel regulator pressure. If that's the case, it's hard to go by the numbers that Mazda lists.
