They don’t sell injectors, just clean them, but they have a bunch
of pictures on their site that may help you find the correct one.
What is it about the injectors that doesn’t fit? Top or
bottom wrong size? Too long? Too fat? When you say you bought
the stock Mazda injectors, what generation do you mean? Renesis??

Chris,
Try calling RC Engineering. They do all kinds of injector cleaning sizing. Kind
of like Gami but for cars and motorcycles. They can prrobably advise you on the
injectors to use for the size holes you have. Phone is (310) 320 2277, and they
are located in Torrance CA.

The
list is WAY too quiet. So, I thought I would pose this concern/question.
I am wanting to get new/rebuilt injectors. I tried to get some a while back and
ordered 4 Mazda injectors. It was at this time I discovered that the stock
Mazda injectors do NOT fit the Mistral intake. My former build helper
originally found the injectors I have been using. The are seriously mismatched
at about 550 cfm and 1600 cfm. I know the EC2 can compensate (perhaps with some
difficulty due to the extreme difference), but I am wanting to replace them all
with about 550ish injectors. Perhaps it will help some of my leaning issues,
perhaps not..
I am having a couple of issues. First, getting the right PHYSICAL size. While
the ones I am using in the Mistral Intake look a great deal like the Mazda
injectors, they are different in physical dimensions. The ones I have come back
with a Chrysler (Deko) and Ford Part numbers, but seem to be very old part
numbers have been difficult to find online (my local auto shop and speed shop
has been no help...I seem to know more than they do about the topic even though
they did try to help). Are there "standard" known physical types with
some kind of verbiage that will allow me to get the proper fit? Or do I use my
calipers, go for the couple of sets I have found with dimensional drawings,
order them and hope for the proper fit? I just do not know the
"standards" used and I yet been unable to find the answer
online....gee, I may have to resort to live persons in an auto electrical shop
<g>. Some of the injectors seems short and stubby and some long and
skinny...some, indistinguishable to the untrained eye, like the different ones
I have now.
I know, due to my ignorance, I may be making this harder than it is, but hey,
it is part of the learning.
SECOND. Since I am ordering new injectors anyway, I am curious about the
impedance. The current ones are low impedance. Thus, I am using the resistors
in series with each injector. I know the EC2 does not seem to mind this at all,
however, since I am replacing them, is it wise to remove this minor failure
point (the connections to the resistors etc) and buy high impedance injectors
and remove the resistors? Does one have a significant advantage over the other?
Seems if you can reduce the parts count (heh, like in the rotary), it may be
better.
Thanks guys. Hope this helps pick up list activity a bit too.
All the best,
Chris
