Hi Paul,
Early in the week you posted that you where going to check the flow of
the 5 injector. I was wondering if you could do me a favor and measure
the length of the series 3 injector from the 2 shoulder that they clamp
up against.
I have completed my test on several air duct shapes and will post them
when I get time to draw the final shape and write my conclusions of the
tests.
Regards Don

I assume you mean the 1993 and later RX7 injectors.

It is 43 mm overall and 18 mm from the shoulder to the end of
the metal barrel.
