injectors

[tomtomiS]

is there any difference between injectors on 325i's. ive just won some sport injectors on ebay as the car had done 90k. gonna put them in my touring but just wondered if they were any different. ta

Don't quote me on it but i think they changed with the face lift.

I think pre-face lift were low impediance and face lift are high impediance ?

[tomtomiS]

i bought them so i could get them sonically cleaned or whatever it is and then fit them to the car and keep the old ones as spares. what does the impedance mean?

[Andy335Touring]

what does the impedance mean?

If i'm right about them changing you can't interchange them as it frys the ECU i think ?

[Turbo-Brown]

The injectors from my chrome bumper measure 16.1ohms (high impedance) across the terminals.

Part number ends in 715 if that's any help

[Andy335Touring]

May be they didn't change then ?

[tomtomiS]

ok cheers guys im gona have to wait until they arrive before i speculate anymore on what to do. will post up the part numbers and see whats already on the car. if they wont work ill just sell them on

Details on injectors below.

6 tested good used 19lb fuel injectors from V8. 4 pintle Design II

These are an upgrade to the tiny 14.5 lb stock units in the M20 B25.
Upgrade to M50 injectors since they flow 17.5 lbs
Also serve as a small step up for M30 B35 liter engines.
They drop right in with not modifications to rail or harness.These are a great upgrade because they flow much more and are 4 pintle not 1 for better fuel atomization.
Flow 19lbs @38 psi or 20.3 lbs @43.5 psi. or 21.9 lbs @50.7

43.5 psi is what most 80s BMWs run at.

50.7 psi is what most 90s BMW run at

Bosch Design II 4 pintle

i think its hilarious how they think the motronic magically readjusts to using 30% larger injectors. Its all O2 sensor.

just for the record i didnt buy sport injectors hoping to get more power, im hoping they're the same as i only want them as they will be in better condition and be cleaner than whats in my car at the moment. car is an 89 325iA SE Touring.

all 325s were motronic so use the high imp ( Z ) units, clean and fit then dude, no issues

the Jetronic cars use low imp units ( saturated ) these are not interchangable with motronic ones unless a flyback resistor is employed ( dont ask, just dont do it )

325e use low impedance and they use motronic
