eg. are gtr injectors stright fit..rx7 certain models..aftermarket sard..mazda miata 550cc?etc etc

on same note,what are the signs injectors on there way out,or need of replacement or service.

RX7 turbo injectors or GTR skyline injectors, the 7's injectors are better for your plans davio.

with injectors on their way out.. the thing to be looking for is leaking. how to find leaky injectors is when it is hard to start when cold (the injectors have been sitting for a while, slowly flooding the engine).. i cant think of anything else.. when you get a new set, MAKE SURE you clean them if they have been used before!!! get them ultrasonically cleaned, best 100buks!

when injectors need servicing, they will tend to flow less cc and it can mess things up on boost! make SURE they are clean

also clean then as close to installation date as possible, (up to 4 weeks max.)
so many people clean them and the leave them on a shelf or something. allow contaminents to build up again.

i also think mitsubishi, in the 4G-XX motors use the same type of injectors also.

yeah cleaning a must if used..so series 7 rx7..and the 4G mitsi motors and syline injectors

89sp1.8 · 06-02-2008, 09:23 PM

these are a vr4 setup..4g63..so something like this 'should' be straight fit?

yeah essentially...

I still recommend the skyline GTR 444cc injectors. I get good economy and
grunt when I need it. They are a straight fit just need a larger top o ring
to suit the gtx rail. They are a square plug but do them when you do your ecu
anyway it will be a small extra cost to change injector plugs.

whats the difference between low and high impedance? pro's and con's...

This is a pretty good explaination for you. Just ignore the stuff when they talk about their stuff specifically, but the charateristics are still the same.
