The stock Mazda injectors (normally aspirated) are around 50 lb/hr.  One
builder got away with using 36 lb/hr parts but I wouldn't recommend anything
less.  The EC2 can be used with either type (low or high impedance) but a 5
ohm resistor in series must be used with the low impedance type.  (This is
what Mazda does too)

I used the diffusers on the primary injectors but not on the secondaries.
Didn't seem to make any difference at high throttle where the secondaries
kick in.

OK - 36 lb injectors are expensive - $370 for a set of 8 at Summit.  42lb are $459 and 50lb are $600 at Downs Ford.
