Bigger Injectors for ZE...

[zzzoomx3]

i'm wanting to upgrade the Injectors on my ZE - whats the biggest stock Mazda injector i can use?

Yes, i have already searched the forums and did not find whatever post this has already been answered in - if in fact it has

[fieromx3]

millenia S injectors drop right in... they are 280cc

[zzzoomx3]

ahh - thank you - direct, to the point and no b.s.

what cc are ZE injectors?

[wytbishop]

180cc if I recall correctly.

There are other mods to allow other larger injectors to be used, but unless you're turboing I can't see why you'd need to. If you are planning to go big boost, there's a lot more info on the ZE on Probetalk.

[zzzoomx3]

no turbo - yet -just want more gas - just experimenting with some stuff, especially now that i have an FPR

will that drop in as well?

WALK AWAY FROM THE MILLER CYCLE ENGINE!

Seriously though. It's been done but it's a beee-otch and the modest power is NOT worth the effort.

Most of the information is in the answers given but after reading all of them it is
still a little confusing because some of the answers are wrong.

If you want larger injectors you will be looking for late 90's Mazda Millenia S model
injectors. It has a 2.3l supercharged motor.
Stock KL injectors (2.5L) are 220 cc ZE or DE
Stock K8 injectors (1.8L) are 180 cc
Stock KJ injectors (2.3L) are 280 cc
The injectors are a direct drop into your ZE fuel rails. But you will have to
remove them from the KJ rail and swap them with your KL rail.
Also The car will run like crap without a way to adjust the fuel pressure. So an FPR
would be a good addition also.
This has been tried before without any real benefits unless your going FI in the near future.

klze will make it slower if rich


I have a wideband and afpr.. when i make it rich, it runs slower lol

millenias is MORE than enough. Nissan injectors will make the car stall, way to rich. Even with turbo and no stand alone nissan inj are to rich. I had millenias installed with my turbo and it was WAY to rich under idle.


But if you want to run rich, upgrade your fuel pump. with just the pump i run rich at idle and under wide open throttle.. at 10 afpr! way to rich :S
