M44 block and M42 head will it work?
 

Actaully I am thinking of

M44 block and a P&P M42 head.

would it work?

not for a daily, but for a track purpose car. I have some other ideas as to internals as well from the S42 thread on BF.com

but I have a M44 with 140km on it sitting in the garage and figured I try something. Might put this in a 95 Ti or 91 318is which ever I find first.

i dont no but try it

It will work..on bf.c a guy named gizmo did that plus a different crankshaft, pistons, etc. He made a 2.1 liter motor. It put down 168rwhp and almost a mile high.

EDIT: reread original post obviously you are talking about the same thing. He used M42 head and M44 block. If you get the M47N crankshaft let me know where you got it...I am wanting one too.

wonder what that would do with a DASC on it. anybody know if that's been done?

what's the advantage to using m42 pieces over m44 pieces? are they pretty much interchangeable? could you still use the m44 sensors with the m42 head to retain OBDII functionality (mostly for purposes of the DASC Stage III kit)?

well the m44 has oil squirters for the pistons.

the M42 has the better internals


I'd rather have ODB 1 over ODB II

Well, in general the M42 is a stronger engine due to its forged componenets, the head flows better, more counter weights on the crankshaft. The use of the M44 block is just to get a larger displacement to start with.

M42 also has oil squirters, but they are in a different location...from the bf.c thread

well, if one was going to bore it out anyway, one would be replacing the internals regardless, right? and if i'm planning on the DASC, i remember reading that they couldn't do all the tweaks (stage III, etc) to the DASC for the m42 that they could on the OBD m44. would this necessitate the use of the m44 block and head? sorry, i have about zero knowledge on this stuff :(

can you give me the link

bump i need to learn more about this

i think i'd just call someone like VAC motorsports and ask them.

that's a great thread! thanks for posting that Alaska. now i REALLY don't know what i want to do ...

thats a good boy

thanks for the link
i bought a M44 from a crashed Z3 for $250 and im just trying to get all the parts i need to make this happen

Give me an update! Seems like i just got a m42 head w/m44 block. Let me know before i drop that in, thanks!

Yes they can be swapped. Hopefully your cars wiring is for the M42 motor or you might have some issues. I run a M42 block, M44 head and M47 crank. Runs very good with lots of boost :cool:

Hey johnboy! Well i believe the block ended up being a m42 because the crank position sensor isnt in the lower side of the block. Darn it!

So i would just get a m42 harness and a m42 DCM right? then i should be good with the m44 conversion m42?

Thanks man!

Any particular reason you used the m44 head? I haven't heard of many people choosing that head over the m42
