can anyone tell me the size of the fuel injectors for the 3sfe and 3sge? and are they interchangeable? for example can i put 3sge injectors in my 3sfe? just curious.

200cc I believe for 3SFE.
And im not sure if there interchangable.

^ Is a site with 3SGE listed as 250cc and 295cc.

are they both 200cc? or is that just fro the 3sfe?

Injectors for a 3S-FE come in high (13.8 ohm / dark blue) and low (1.7 ohm / dark grey) impedance.

According to the link, 3S-GE injectors are high impedance (13.8 ohm).

So if your current injectors are low impedance, you need a resistor pack to use the 3S-GE injectors.

^ You sooo just bet me too that...

the reason why i asked is i thought maybe the 3sge injectors would be bigger. it was just a thought. thanks for bothering guys.

in a couple of days i'll be talking to a performance place about working the 3sfe (port polish, ground cams?) just to have an idea whats available. i know no one makes sports cams for this motor, i thought maybe these mods (if they can be done) combined with bigger injectors would go well.

i know ive been talking about putting in a gen3 3sge in my car but i would really like to have a go at workin the 3sfe.

They are bigger. Flow wise.

hey 88...

When i swapped my motor, i had to use the USDM fuel rail, but i switched the injectors with the thinking that they would be cleaner and less likely to give me any problems.

well the question is, the injectors from the JDM engine are bright yellow, versus the dark blue ones that were on there orignially. I havent had any problems, but i was curious to what the differences are, do you have insight?

^ No idea what the differences are besides the color.

Do the injectors look different besides the color?

Tommy · 03-18-2005, 03:24 PM

no, not that i noticed. like i said, they work fine, havent had any issues with them. must just be a JDM thing
