Wendell,

If you want to avoid the machine work, there are places that sell = RX-7 13B=20 fuel injectors. Here is one URL

http://www= .fiveomotorsport.com/Injector_SetsMAZDA.asp

http://www.coximport.com= /store/13500055

there are others as well

While the injector sizes are the same the flow rate varies = depending on=20 year, type engine (turbo or NA), high or low impedance (generally = referred to as=20 Peak & Hold (low impedance) or Saturation (high Impedance). = The EC2=20 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=20 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.
