    Just wondering if anybody knew the difference between the MBN Injectors and the ones used in the 6NZ's.

    Do the MBN's just flow less? I know the same injector is also used in the BXS. Seems they have recently changed the part numbers. The reman for the MBN is 10R-1000 and the new is 2295919. For 6NZ it calls for reman 10R-0956 and new is 2113022.

    I have a truck with a MBN and #4 injector is going out. I have a full set of injectors from a 6NZ, so im guessing the best bet would be replace all 6 injectors with the 6NZ ones instead of just swapping the one. If they flow different then the one cylinder would run hotter then the rest and probably cause the engine to run rough as well.

    Mr haney told me that they flow the same amount of fuel. The otehr day i was looking at some injectors of a 3406E and some MBNs side by side and the mbn look like they have bigger tips. I started gathering parts for doing the inframe on my MBN i was planning on getting all the guts off a 6nz maybe 58s and a marine cam after i removed the silencers i fell in love with my T800 :biggrin_255:

    The flow rate of a MBN and 6NZ are the same. The part number you've listed for the 6NZ isn't the injector for the 435 hp or higher hp engines. The part number should be 211-3023 with a reman number of 10R0957 or the new reman number of 10R-8501 to have the same flow rate as the MBN injector.

    The injector you have listed for the 6NZ is a low Hp 6NZ engine, injector part number 211-3022/10R-0956. The flow rating on this injector is 15% lower than the MBN or 6NZ injector used in higher hp ratings. You do NOT want to install these injectors.

    The MBN tips do look like they'd flow a lot of fuel, but they don't. The holes in the tip are tappered for a different spray pattern to try to atomize the fuel better. CAT did this trying to get a higher combustion effiency rate for less emissions and hence a smaller fine from the EPA for selling the bridge motors.

    The cheapest fix at this point is to buy one reman 10R-1000, unless of course you have 6 of the 211-3023/10R-0957/10R8501 otherwise your 6NZ 550 hp will be a 465 hp with the six 211-3022/10R-0956 injectors when your done.

    I will have to double check SIS. I thought that was the number it gave me for a 475hp 6NZ. The injectors I have from a 6NZ are newer so they should be the 8501's.

    If they flow the same what would happen if you were to put one 8501 in the hole from the 1000?

    I priced the 10R1000 and 10R0956 and the 1000's were about $70 more. Maybe cause they are bigger then the 0956's

    I wouldn't mix match injectors. The flame pattern emitted from the tip is different even though the fuel flow rate is the same. I've had people install the 10R-0957 and the 10R-0959 with the stock MBN piston anf have no problems with doing this, but they've always done it with all six injectors at the same time.

    The 211-3022/10R-0956 injector is a 6NZ injector, but it is used in the 375 and lower hp rated engine. The 435 hp and higher hp engines use the 211-3023/10R-0957
