But that limits
me to using the 550cc injectors. 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.
Cheers,
Rusty
