B20 injectors on B25

[ADEN]

I have a new set of white M20b20. Can i put them on M20b25 with no problems?

what's the bosch p/n?

No to white on b25 . Those also are ran in the etas just look for blue 14.5 per hr i believe

What might happen if i do put em in?

those are low impedance injectors they may fry something electric. i would source a high impedance set

How come!? Same set is installed in my 320i Bosch met. V1.3 for years with no problems.
As per the pic below they are high impedance mine test 15-16 Ω.

if they are low impedance then fine, when i searched somehow they appeared to be low impedance. can just measure rsistance across pin to confirm

I confirm they are 15-16 Ω but am i ok running them in b25 at 2.5bar regulator from b20?

116 g/min = ~116*60/1000*2.204 = 15 lb/hr
SQRT(2.5/3.0) = 0.91

so flow will be 0.91*15.3 = 14 lb/hr so its only 7% less than stock

should run ok with O2 sensor feedback with the ECU is functioning correctly and engine is stock, if you can get 3b regulator there will be less corrections going on wihtin the ECU.

Thanks alot digger i guess i will just use them and see how it goes.

Update:
I got my hand on 3.0 bar regulator bosch 0280160258 it appears to be for the 4 cylinder engines i hope this will help b20 injector to flow better in b25 engine.right?

It should
