Lmm vs lbz

[Mpsoldier]

so there than dpf and turbo specs whats the difference in the two motors pistons? injectors? Rods?

 

[LWATSON]

I dont know about the injectors but I'm pretty sure the block and internals are the same.

 

[Mpsoldier]

thats what i am trying to figure out.
head's flow the same rods and pistons are the same?
idk just curious. have both and just keep looking at them.

Turbo is a different part number, IIRC, exducer dia is a little smaller.

Rumor had it that the cyl head P/N is different and has a thicker bottom to resist head gasket leaks. I can't verify that.

I know the pistons, rods, and injectors will work in both motors.

ok if you had a choice to build a lbz or lmm leaving motor stock which would you choose.:thumb:

 

[TeaBagger2006]

Lmm injectors are six hole and lbz are seven hole. Lmm egr is bigger

 

[LWATSON]

Mcrat mentioned the possibility of the head having a thincker bottom to resist head gasket leaks. This is the only advantage I know of that would push me towards the LMM. One would probably do just as well as the other.

Lbz's came in better looking trucks so i vote lbz :thumb:

I know the pistons, rods, and injectors will work in both motors.

I heard the injectors won't.

 

[kjp800]

The injectors will swap between the two

 

[emiller3]

I have a set of lmm injectors in my lbz at the moment.

so will LMM heads work on a LBZ? i hope so the guy insisted they would when i purchaced them and now they have all new parts in them ready to be instaled in a week or so can anyone verify if they will or not please thanks guys!!!!

The LMM was designed to handle more heat soak from the factory bc of the DPF regeneration process so I vote LMM over the LBZ bc added hp equal excess heat over stock............
