lol, I thought the poster was poking at me. lol amazing what comes up when you just google 'nira' lol. I'm such a dip ****!!!! lol

Ok, I'm done laughing at myself. Thanks crackerman. It appears I have several options with stand alone ecm's. The nira may work with all the BMW sensors.

nope sorry! lol imo you would be better of with a stand alone instead of a factory style ecm.
 
Yep, thanks jlbayes. It's gonna take folks just like yourself to get this thing going. Any and all help is appreciated.
 
Well he11, I didn't win the auction for the totaled BMW. I went to $5,500 and the thing sold for $6,500. To many unknowns on this one to bid to large.

Just have to wait on the next one to show up that's not in CA.
 
How much money will it cost to reach 600hp with the BMW? And will 600hp at xxx pounds lighter even come close to what you have now with the current cummins setup.

Good question. At this point I can only speculate on the weight. I'm guessing the cummins engine in the truck now weighs roughly 1100lbs. We didn't have a good enough converter to attempt a dyno run so a guess at HP would be somewhere around 700HP (no nitrous). This would get the torque to somewhere around +/-1400 lb-ft.

I'm guessing the stripped down BMW 3.0L would weigh somewhere around 600lbs. This would be no turbo/turbos. I still think, even though I have no positive info, that this engine can make 700HP. Keep in mind, with the smaller/lighter rotating assembly & valve train, this engine could be spun to a little over 7000rpms if I can get the programming to do it. The torque on the the other hand is a different story. I'd say the torque of the little engine wouldn't exeed 900 lb-ft.

The all aluminum water block cummins with an aluminum head would have saved me close to 380lbs. This would have been the sweetest thing ever.

As JQ stated, we haven't begun to see the full power potential of the cummins. Our pump hasn't been moved of the 650cc setting since we installed it.

We'll find out when we get a filled block and lean on it in Craig's little Jeep. As far as actually being quicker with the BMW, it isn't a big concern with me. Yes I want it fast, but, I want to do it with something different.
 
Thanks matty169, I haven't done a whole lot of googleing.

With this information and some help from folks on here, we can surely find the limits of the engine on paper. We have 3000psi of cylinder pressure being used from the factory. Anyone know what a hopped up Cummins's cylinder pressure is??

The article mentions the strength of the aluminum block being the limiting factor which I had sorta figured. With the genius sleeve/bolt of the head/main design, they must be worried about the cylinder walls.

I also see that an '11 or newer will result in stronger rods and crank.

I'm not sure where you got your weight info. I hope you are correct. At 480lbs, this thing is going to fly without modifications.

With the drag set up, the truck currently weighs 2768lbs. If I'm correct on the cummins weight of 1100lbs, this would mean a loss of 620lbs. This puts the race weight at 2,148lbs. Of course, all this is pure speculation until I actually get one in my hands and do my own weighing.
 
The 2011 2.0 BMW diesel engine weighs 161KG.........220ish KG is a guess

Ok. By next week, some of he guessing will be over. I have made a security deposit on two '11 model N57 deisels.

They are not, however, the N57S engine. This is the engine matty169 posted the link to above. I'm hoping the engines still have the sleeves connecting the head and mains. I've googled till my eyes are crossed and can't seem to come up with anything.

Looks like theirs no backing up now.
 
Leiffi on here, is over across the pond and expertly playing with euro trash diesels, he could probably give you a good heads up on what to expect with the bmw. IMHO you were just getting started with the 5.9

Yea, I looked at some of his build. I had another thread about using the BMW and was directed to Leiffi. I think I even PM'd the 'ol boy.
 
Don't know much about those smaller euro diesels, I have a BMW but it's gasoline M3.

I believe they have potential, stock 335/535 injectors make about 350 hp and 900 Nm torque, with small turbo, without smoke for street use.

Tall Boy might know more about them.

Me neither, but, I'm learning. The engines I am getting our actually M57 and not the N57. As far as structural integrity goes, I don't think they are much different.
 
I wouldn't bother converting to Cummins injectors, BMW originals should flow enough with enlargened nozzles. I think you can also mod original CP3 to higher flow, or use duals. You might also want to ask price of Adaptronic standalone from tall boy, might be cheaper and better than NIRA. I would use original ECU but I don't know if theres anyone around you who can tune it.

I'm with ya on the injectors. I won't know for sure what type of injector I have until I get the engines. I guess some of them had the Bosch Piezo and then some had the solenoid style. Regardless, I will certainly get all I can from the BMW injectors 'cause I doubt the cummins stuff will just drop right in. lol

From my research, the pump is actually a cp4.2. I do believe they can be modified for more fuel. Any double stacking will be totally custom ($$). The duel idea is not out of the question if I need the extra volume.

Sounds like I need to have some discussions with 'tall boy'. Is he a member on here??

And yes, my thoughts exactly on the stock BMW ECU. Not that it isn't possible, but, why do the extra expense when the folks here in the USA can get it done.
 
The lml duramax went to a cp4.2. Hey have a funky timed operation that pulses inthe pump happen upon firing of the injector. A cp3 has smooth pressure increase, An "upgrade" is a cp3. Thankfully you can add two like an alternator and just belt drive them.
