Thread: 02-05 wrx top feed baby blue injectors

No. They are 11ohm.

Thats what i thought but then i heard this and it made me think twice about it.

If you use low impedance (2 ohm) injectors as in this example you’ll need a 10 ohm resistor in the wire going into each injector. It turns out that B15/P11 injectors (not sure about B13 and 14 and P10s) are high impedance (12 ohms). Going without the resistor the car will run incurably rich because the injectors will essentially be stuck open every time they fire.
RE-EDIT, FINAL SOLUTION: I got some bunko info on the injectors needing to be high imp., they should be low, so the MSD bolt right in and don’t need resistors, just different clips. Trust me, my car ran like crap with the resistors in. So, to be clear NO RESISTORS!

wrx/sti top feed injectors are skinner and shorter than the average MSD.

Is there any type of modification to make them work then if their shorter?

You'll need different o-rings if they're skinnier, but as far as being shorter, I'm not sure.

FWIW, anything more than 10ohm is high impedance. Anything lower, is low impedance.

spacer, someone made a spacer. that's what i used on my taco.

Well if that's the case that's sucks cuz I already bought a injector o ring
Kit from Deatschworks. I thought they was direct swap?

i could make a space just mad because i already ordered a set of stock wrx o ring kit from deatschwerk. Now idk what im going to do with a worthless set of o ring kit. GRRR!

Does anybody know the correct size o rings i need to get to fit the wrx injectors in the rail/manifold? Found zero amount of info on this kind of swap.

There's gotta be somebody thats installed a set of baby blue wrx injectors in low port RR.
