Wondering if anyone has ever changed the mazda fuel injection over to a constant injection like the old Saabs and others had ..?? they also had a high pressure fuel pump and although they were piston and valve they also liked a high volume of air. I am only thinking of this for racing purposes not street .. The constant system has a lot less components to go wrong and has it's own tip over switch built in . Do you think it would work on a rotary? Please don't tar and feather me I'm just wondering..

 

No reason why it wouldn't work as long as you can plumb in the metering plate and get some injectors of appropriate size.

Nothing really goes wrong much with the electronic fuel injection except worn out TPSs and clogged injectors anyway though. The CIS systems, in my experience, are far less reliable.

 

Right-o the next project I do I will learn more about the mazda system and try it out .. This system is a little complicated for an old fart but I WILL figure it out so I am more comfortable with it .. Thanks Arron Buy the way your rebuild video on the cosmo is great ...
