30d - 40d/50d conversion

[mathias]

I cant comment technically but would imagine the 30D & 40D are very close...think its intake and turbo....M50D i think will have much more difference.
there was a swopped 1 series in Speed & Sound...140D...swopped from a 6 series i think.

O wow, thanks for bringing this to my attention it was a great read... the 140d is an absolute beast but has a lot more done to it over and above the engine swop.

single larger turbo on a 3.0d is probably the most economical path. Has been done, and from what I hear power figures are good

This is the correct answer. It is not a cheap exercise, but a few guys have done it on their 30d and achieve around 330kw and 800nm+. RK and Madness have cars that have done this.

Thanks Gents, have been following Madness for awhile so I'm aware of the bigger single turbo option but this comes with other issues, was hoping for a "simpler" OEM option...

My thinking is that BMW would have done their research and opted for the various turbo options for a reason as I will be using the car as a everyday drive, then there is the fact that these OEM parts are readily available both new and used.

Will do some further research on the OEM 40d/50d parts otherwise the bigger single turbo option will definitely be a feasible option.

You mention some words which spark a very eay answer for you "simpler" "Other Issues" "Daily drive"

Go drive the 30d that was done by Sherwin, and then decide from there how far you want to stretch into...you want a simple and reliable daily drive with power to punch when you need, a well boosted and maintained 30d is not bad at all.

---

Thanks Ash, was there ever a thread made for Sherwin's 30d? would love to give it a read. Ive only come across the 30d which was tuned by Madness
I realize now that this "conversion" wouldnt be very simple at all! As most of the external components would need to be exchanged, was hoping it would be as simple as swoping the turbos and giving it a flash but based on all the very helpful answers above this doesn't sound feasible at all, I could potentially replace components as/ if they fail with 50d components one at a time but this would probably take forever as they don't fail easily.
So yes DP, DPF & ERG off with stage 2 tune sounds like the way to go. Might add Meth injection at a later stage if cooling becomes an issue with the stock intercooler.

No thread made for his X5 30d that he flashed bu DM me and I'll send you details to chat some of the okes. 
From what I have been exposed to, a decent Stage 2 map with DP will yield great results. You will need Meth and more once you want to start realy pushing it up a lot more. Some guys are running DP and Stage 2 for over 3 years and then they out on XHP to change and more improve the driving experience along side the ZF service for the gearbox for longevity. When you want to start fetching above 250wkw and running towards 300wkw then you start looking at hybrid or bigger turbo, them meth & intercooler upgrades etc...but then also, you throwing reliability out the window. Then you car has a mind of its own and its wayyyyyy out of its tried and tested comfort zone...

@"Kish2604" is correct, from the F15 line, 30d engine code is N57N, 40d is N57Z and 50d is N57X, with the 50d using a different piston and rod according to part numbers at the very least, along with the other variations mentioned above

If the internals are different, that is probably how the different engines will be labeled. However, as per the OP's screenshot, the engines seems to be exactly the same because they are N57D30 for F15 line, 30d, 40d and 50d. So, where can we check you story?

Quick look at just a few part numbers on https://www.realoem.com - 2019 30d vs 50d

Now we are talking about different engines here, OP's questions is in relation to the N57D30 engines and not the B57D30  :dunnoanymore:

What part of this do you not understand: N57N, N57Z, N57X

The D30 simply means 3.0L

Yasis the bakery opened early this lockdown!

Interesting thread, thought the engine internals would be the same. This is only what I have found. I don’t mean to cause any confusion. Anyway time for the bakery to close

Thanks Quinton

Appreciate your assistance! unfortunately it doesn't look like this will be a feasible conversion...

Dude, stop being a tool, you asked for where the info came from, I gave you the resource, use a little bit of brain, navigate the site and see it for yourself, if you don't believe the info I posted.

The part where you expect me to take your word as gospel instead of providing proof like @Quentin140 did. That is all I kept asking for, but No! you prefer to open the bakery. With the amount of fake news and fake experts lately, you will be a fool to believe everything people put on the net. You can close your bakery now :chef:

On the side note, thanks for the thread OP, learned something new. Always thought the engines are the same 

 

[AshG108]

Ok ok ok...gentlmen!

We all learnt that the 30d vs 40 vs 50d has different engines! Tops!

Matt- Hope you got some clarity and you always welcome to contact for further details or anything for your journey forward.

To the other gents, the fkn internet is there on every device...and so is RealOEM...lets take a stab at using a 1mb or 2mb when having an amicable debate.

Leave the bakery opening and closing times to the government and lets enjoy our BMWs...whether small 3 cylinders or big 8cylinders...

I've spent some time on realoem comparing just the 30d motor to the 40d motor and everything is the same, I was wrong. When I was looking at X5's I asked the question of what the difference is between the 3 engines as well and remember being told by the salesman that the internals were different in addition to the obvious turbo differences. I just accepted that this was correct and did not question it. My apologies.

If I was you, I would start with the basics. Add Dp and SW. Enjoy that for a while. Then you add to that.

And please don't go and speak to the tuners! Speak to the guys who's done the work on their cars!

Have a look at my thread and you'll get a clear indication what the car can do

Oh and what I ment is speak to a F-series driver, not a E-series. 
The F-series is a little bit different. Also the X3/X4 is different to the F-series with the transfer case and and and

Thanks Cornel, Have been following your thread for awhile, enjoyed watching your youtube vids as well!

Would love to see what else you do with the car in the future!

but I must ask, what do you think of the cars suspension? I don't know if there is something wrong with mine but I really don't enjoy the handling at all, have had the car inspected by BMW as well as Best Drive and the conclusion was that I just need new tires... which I do agree with but can't imagine tires alone being the cause. Car tram lines horribly and I feel like i'm constantly fighting with the steering wheel to keep the car going straight, even when not under power.

Hopefully we can do some things to it this year. Will see how it turns out. 

For me the car handles very good. X-drive helps a lot between corners. Only time I struggle to keep it straight is when I launch at Tarlton. So if BMW said your suspension is fine but you need new tyres, maybe start there. Tyres can play a big role on a X-drive car. Also make sure they RFT all round and not mixed(rft and non-rft).

My spotless E70 40D oil pump packed up and have a bearing knock. 125k km - spotless. The 40D engines are nowhere to be found. Could i just install a 30D in the X5? What changes has to be made?

Bakery is back open boys!!!

 

[tommienor]

Find me a 40D motor and we'll close the bakery - no one wants to rebuild or know what they talking about. Just need some advice of where to go - Id like to get it back on the road.

Not sure where you based but Bavarian Breakers are in Edenvale & Midrand, you can also check in with MD House in Wynberg.
They can possibly have an engine there or if you looking for parts towards this.

Is the cost of repairs more expensive than replacing the engine?

Thats what im being told - They would source a secondhand motor (which will take months as they scarce) - Replace it with an upgraded oil pump. that would be in the region of R120k. Rebuilding the original engine in the region of R200k. Hence my dilemma.
