I had Bruce T. send me some rebuilt fuel
injectors and the no. on them is 1955002010, all four are alike. I have
been reading here that there is a difference between the primary and the
secondary. Will these work for both, if not which ones do I have, primary
or secondary? There some options other than the Mazda, correct.

Hi John,
Attached is a chart that I stole from somewhere,
showing the numbers for some of the stock injectors. As you can see, you
have 89-91 non turbo injectors. They are high impedance, so they
will work directly with an EC-2, without having to add resistors.
They are "rated" at 460 cc/min of flow, though I believe
that's at Mazda's lower than standard fuel pressure.
The stock injectors are the only ones I know of that
will fit the stock housings, or manifold, but I suspect that are others out
there somewhere that will fit. If you're using an
aftermarket throttle body with injector ports, then you'd need to use
what's made for those. It's sometimes possible to adapt other injectors to
fit the stock Mazda ports, but it's much easier to just use the ones
you have.
As for matching injectors, Mazda used 4 identical
injectors up until 93, when they made the secondary larger than the
primary. This was to supply lots of fuel for the twin turbo
engine (zoom, zoom...directly to
jail).
Cheers,
Rusty (hoping to sneak past the
spamcatcher)
