Default WRX fuel injectors, high or low impedance?

Stock WRX injectors, saturated high impedance type, or low peak and hold type?
Thanks,
Greg D.

Are you guys sure they are high imp? I thought they were low Imp?
I'll check the manual tonight when I get home.
Thanks for the input.

Austin,

Could you please take a volt/Ohm meter and measure the Imp on one of your old WRX injectors?

And if you have a digi camera send me a closeup of the electrical connector?

Reason? I am going to 420-460cc injectors on the GTX with a new HKS chip and the WRX injector used is cheap as heck. If it fits I am all set. I just need to see what its shaped like to make sure.

I have been watching Ebay for used 460cc RX7 injectors but by the time I get them, send them to RC Eng for cleaning I could have bought 2 sets of WRX 420cc injectors which would be in good condition.

Thanks so much and say hello to Stacie! And yes, next SCCA event I'll bring the WRX instead of the GTX.

Beer me!

Greg Downing

Thanks Austin, the injector IMP is compatable with my ECU.
Now to see one up close and personal next to my GTX injectors.
I know that the RX7 NA 460cc injectors are a plug and play type.
It looks like the WRX injector plug is rounded where the GTX is square.
Cheers,
Greg Downing
