30d - 40d/50d conversion
#1
Hi Guys

Forgive my technical ignorance but has anyone tried to convert their 30d into a 40d or even better a 50d?

From the info I have found thus far the 30d, 40d & 50d are all the same engines (N57D30) but each has a different turbo? The 30d has a single turbo whilst the 40d has a twin-turbo and 50d a tri-turbo.

Wondering if it would be possible to buy some x5 40d or 50d OEM parts (either new or rebuilt) and put them on my 2013 x3 30d (F25) (which also has the same N57D30 engine) to make this a 40/50d then do a straight pipe with software for some serious power. Assume there would be other mods required as well but from what I have found thus far biggest difference is the turbo?

Have been wanting to do the straight pipe, Dp, DPF & EGR removal with a stage 2 software in any event so this might be a crazy but worthwhile initial purchase to prevent duplicate purchases at a later stage…

*Yes Lockdown has me very board and dreaming

Came across the following article on Speed hunters but this guy did an engine swop, I’m looking at possible OEM differences between 30d, 40d & 50d as the x3 only came out in a 20d & 30d in SA.

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.

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.

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.

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.

A 40d has different internals to a 30d as well. But you can get the performance of a 40d with a simple stage 1 flash on a 30d.

Can you refer us to a source to confirm? The document attached says all three are N57D30 engines with only the number of turbochargers used, as the difference. I would assume if the internals are different, the N57D30 number will be different .i.e N57D30XX or something  Fencelook

To get a comprehensive list of differing parts between the 30d and a 50d one would need to browse realoem for p/n and compare. At the top of my mind would be injectors, turbocharger/s, piping for the same, probably a bigger cooler from factory to handle the volumes being dispensed by the tri-turbo setup, a different ecu to control the 3 turbos, possible intake manifold differences, different radiator and oil cooler, definitely a different gearbox to handle the additional torque (it would still be a ZF but a different model in the family) and so on...

it is definitely possible but only with a large wad of cash, some diy and electronics understanding as well.

@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

Agree with Bazza, did the same with my X5 30d and a downpipe, it has made a world of difference to the cab. Happy for you to take the cab for a drive to see the difference if you are in Jhb. Did mine with Sherwin and the guys at the 357. Excellent service

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?

The engines are different, almost everything is different from 30d/40d/50d with the exception of the ecu!

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.

Please point us where we can find information supporting your statement. Below is the information saying the 30d/40d and 50d uses the same N57D30 Engine. You can also see that the 25d, 35i and 50i uses different engines as shown which is clearly shown by different numbers i.e N47D20,N55B30 and N63B44TU

I will agree with @Kish2604 that the difference is with the components around the engine, like intercoolers, injectors, piping, intake manifolds, etc and the ECU. But the engines are the same, with the same internals unless someone can prove me wrong with a solid information.  Tiptoe

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
