That brings me to the next question, what are the injector

specifications

that I should use if I don't purchase replacement mazda injectors?  I

know

they should be of the high resistance > 13 ohm to work with Tracy's

system

but I'm not sure about nozzle flow rates.  Also, are the primary and
secondary injectors different?  Related to the injector diffuser

question,

if you replace the injectors with a different make should they work with

and

fit into the mazda diffuser?

Tracy says the engine needs up to 18 gallons an hour at full power.

BTW least you think that is high you would be wrong. 200 HP aircraft
engines also need that kind of fuel flow at full power.

I would say 20 gallons per hour to be on the safe side. Since there
are four injectors that is 5 gallons per hour or 30 pounds per hour
per injector. I'll be using the stock Mazda 88-91 turbo injectors. At
least initially.

List,
Summit Racing carries Ford 30lb injectors (set of 8, of course) for $210.

Maybe it would be worth just buying new injectors instead of fooling around
with the old ones.

Here are a couple of web sites that offer injectors which meet the needs of
the rotary engine.  The information on injector selection is also helpful.

I bought my injectors from RC Engineering.  They can also clean and test
your stock injectors.
