E39 523 engine swap from E38 740i
 
Hi, i would ask some question if anybody do somenthing similar, or have more knowledge then me.I have now E39 with M52 B25 engine, and have E38 M60B40.Both cars are complete, in driving condition.E39 i can register, but E38 i can't register in my country because i am not in EU Union and only could this engine swap thing.Does somebody know what can i leave on E39 and what i have to swap it from E38 becide engine,diff,transmision, etc.This would be my first project afther this i would finish E28 535i, that's easy.I hope for some answers, or maybe some links.Transmition is automatic, for now :)).THAHKS.

Very difficult swap. I would sell or part out both cars and buy a 540i if that's what you want. Ship one in from another country if you can.

The M60B40 was never used in the E39 540i.

I would buy, but also imposible mission.No one sell it, and in there is maybe 3-4 540i in my country.So if i want to drive 540i this is my only option bro.

Would likely be a failed project: this is your first project; the swap itself is very complicated, if not impossible.

Your E39 has rack and pinion steering; the E38 has recirculating ball. At very least, you must transplant the engine and transmission computer (all one board) to the E39.

u.nanimous 09-05-2019 09:24 AM

There has been companies that make swap kits to drop GM crate motors into an I6 E39 chassis but to swap a BMW V8 in place of an I6 without having the subframe...how much fabricating experience do you have? As mentioned above the steering is different and you might be able to use a lot of the E38 parts but mounting points to the subframe will be a problem. It will also require beefing everything up, the V8 is heavier and has more power (suspension and brakes).
Either wait for a 540 or rebuild your I6 with some forced induction.

Sorry if I have mistakes in writing, and ih my English is not very good.I don't use it every day.Idea about this swap is mine, and I have friend mechanic who would doing this, he is doing mechanic 25 years total, but here we don't have many opportunity to try that swap engine or make some project cars.We would park car by car, and when we take out everything from E39 .Than we would fit engine from E38 with transmition and electronic installation.He know to weld, and welding and cutting part of job is not he's problem.We would like to know what we can use or can stay from that 523 so we don't need to put in from E38.We don't have time limitation for this swap, and both cars can driving, but E38 we can' t registere so we want to do this.Any advice, links etc are welcome.Thaks everybody for advice and help.Best greetings.

why can't you register the E38?

effduration 09-05-2019 12:11 PM

what country are you in? ...even if you get the mechanical pieces of the M60 to fit in the e39, and run, the electrical /computer issues are going to be a huge problem. You could try to use the M60 engine wiring and engine computer in the E39 but it is likely not going to work with most of the elec system of the e39..

Because the car is Euro 3, and we can't buy and import Euro 3 car in Serbia.Owner can drive it and sell it because he is citizen in EU, Serbia is also Europe country but Serbia is not part of EU union.

M60 is very similar to M62, however you will need custom wiring and programming, not to mention a completely different front subframe and front suspension.

edjack 09-05-2019 04:41 PM

I have never read anything on an M60 swap, but there have been several M62 swaps here in the USA.

Use a search tool to find writeups for M62 swaps. The M60 swap will be different, and the differences will complicate the project. You may be able to solve the differences as you progress.

Do you know a BMW specialist?

The E38 in the USA came with an M62 engine, so we on this forum cannot help you.

you literally have anything you need...

your talking about taken a running car.. taken it apart and stuff'n it in another car and running it..

yes it can be done.. Id start by striping everything

Santaclaus4 09-05-2019 07:23 PM

Just use all the parts and make a car from scratch.

edjack 09-05-2019 11:48 PM

I'd be willing to bet that the connectors will not mate up.

Burning2nd 09-06-2019 12:54 AM

if you take the m60, the harness and the intire car out of the e38 and swap it over to the e39 chasis...

you shouldnt have much of any problems..

Your not trying to run a m60 on a m52 platform, your removing the m52 (striping the e39) and replacing it with the m60

you might need to custoem engine mount, and fuel rail something..

should work like this..

strip the e39 to a shell.... put all of in in the corner, strip the e38 to a shell.. take all of that and put it in the e39


lots of work... defenitlty doable : kindda unrealistic though

Mr.BlooM 09-06-2019 03:44 AM

Like I say I am from Serbia, even Serbia is in Europe, we are not part of EU Union, because of that we can't drive EURO 3 cars who have licence plate of any country from EU Union.Only owner can drive it here, and he had new car and he don't want more this car.On some sites which sell cars I fould only one E38 740 and he is 6000 euros even that car I see don't worth that price and because month salary here is 200-250 euros buying that E38 from car dealer don't make point because we have this one almost like a gift.Also E39 540 are very rare, maybe a few cars in Serbia, dealers don't have them.So this is only option to make 540 on my own.My friend is old mechanic, he know to cut and weld, we can dismantled car with easy, but before everything I like to ask does we need to put sometning from that M52 on E39 or just torn apart everything and than from E38 put part by part.We would put all engine, transmition, diff, electroinic installation, suspension brakes everything, I just want to know if there are some similaritys in mechanic part of the car or not for example carter or something like that.We would park car by car and that start the job.This is only option we have if we want to make that 540 run.I know some good electrician guys if there be some problem with harness, but I think if we put all from E38 there is not to be any problems or maybe miner problems to solve.

Burning2nd 09-06-2019 03:46 AM

chasis items are not going to interchange..

suspension and brakes exc exc will not be included,

harrness will

good luck

Mr.BlooM 09-06-2019 03:53 AM

Thanks.I Hope for more answers or guides.

That would be on Serbia though, they are the ones imposing the import ban.

I agree with Mr.Yuck, they try to implement regulations from EU standards to Serbia, even they had month salary 2000-2500 euros and in Serbia people work for 150-250 euros, and price of food etc are the same, even the gasoline in Serbia is expencive than in most country in Europe, and if we compare standard and price of gasoline in USA and Serbia it's expencive in Serbia.There are also problem i heard with project car, if you wanna put for example in E46 another 2.0d if your engine broke, it's so complicated that is more likely you will burn the car and buy another.

That is true however the EU tries to dictate what countries can and can't do. All power comes form people that do not represent the concerns of the people in individual countries.

I'm not sure if I'm missing something. OP is unable to register a car in Serbia, because it was built for the EU market, due to regulations in Serbia. That sounds like that would be on the Serbian DMV equivalent.

Would it be fair for me to say the US sucks because I can't buy a gun here, import it to Sweden and they refuse me registering it there?

Unless it was an OT comment, like "Potatoes blow..." or "I don't like pistachio ice cream".

As far as options for OP: Is the 740 a complete dead end or are the some modifications you could do to it to make it pass registration?

That was a very good explanation.

Hard to explain, and yes bro you are missing the point because you don't know political situation betwen Serbia - Europe Union.Serbia is on Balkan, Balkan is part of South East Europe.But we are not part of "EU UNION" end they negotiate for almost 20 years we join in "Europe" like you try to enter the room, but you are in the room.So we can buy cars from Germany, Spain, Sweden etc but only from Euro 4 and further.Euro 3 we can't buy.Owner of this E38 are live and work in Germany and he put that E38 here.He can drive it because he is EU citizen but natioality Serbian, and Serbians can register or drive that car here.Because of that i want to make that E39 with Serbian plates into 540 with engine and other parts from this E38.Owner don't drive this car anymore, and he have F01 in Germany and he don't need this car.
