Wendell,
If you want to avoid the machine work, there are places that sell RX-7 13B
fuel injectors. Here is one URL
there are others as well
While the injector sizes are the same the flow rate varies depending on
year, type engine (turbo or NA), high or low impedance (generally referred to as
Peak & Hold (low impedance) or Saturation (high Impedance). The EC2
requires 4 resistors if you use Peak and Hold type.
So you need to be certain what you need and what the merchandise is that is
being offered for sale.
NEW Mazda injectors can run up around $235 EACH.
OR you can do as you say and Machine the holes larger.

injectors
Well I
tried to start the engine with no luck. At first had no spark and
called Tracy and he led me through the mistakes (no ground on the coil frame
- thought the underline statement in the manual refered to noise reduction,
not no spark without the grounded case). Got sparks but no fuel flow, 3 of
the 4 injectors are sropped up.
I can find
injectors at Summit - a ACC-150130, 30# flow for $37.99 a price I can live
with if they are of good quality.
Practically all the injectors I find are larger at the fuel rail and
smaller at the manifold end. The ones on the engine are .430 at the fuel
rail and .630 at the manifold.The injectors available are .573 and .574
respectively.
Is it
advisable to drill out my stock fuel rail? How about the larger
manifold end?
All help
appreciated.
Wendell
