I am using the stock Mazda Nippon denso injectors. Tracy mentioned twenty

gallons an

hour max. Should be good for about 50 HP each.

Paul,
    Thanks for the response. You didn't comment if anyone was using a
Megasquirt controller? http://www.bgsoflex.com/megasquirt.html
Also you mentioned the ones you use to be good for about 50HP each, would
that mean if I am shooting for more than a 100HP just go for larger
injectors? I see on a chart I have Bosch makes one used on a Ford at 100HP
each, would it make since to use a large injector and just tune it to the
desired performance?
 Thanks,
    Richard

I am real sorry about that Richard. What a great idea. Build your own fuel
injection computer. Open source software so you can make your own program
modifications. Real cheap.  I can see what I will add right away and that
is data acquisition. This really jump starts anybody that wants to roll
your own. Major major breakthrough.

Couple of things about this system that I really like.
One, it uses the Motorola 68HCxx processor which I already know how to program.

One of the minor drawbacks is it uses a throttle position sensor which
takes a bit of effort if you have to fabricate one. It is still not clear
to me which off the shelf throttle bodies work with this system.

Also it uses an O2 sensor input which will have to be removed from the program.

All and all it looks REAL good so far.
