Swapping M62TU into E46

So... the M43 gave up... took it's beating, and then fell on it's face...

did take a good beating though...

I will be posting pictures of the stuff i've gathered for my swap later, but i wanted to ask if someone knows of a good writeup to learn from...

Thanks in advance,

Motor comes from car with VIN:
WBADN11090GD94869

Transplant car has VIN:
WBAAL11010JN10137

Jolly times ahead

So, here are some pictures for you guys...

This is the organ receiver, some junkie bastards broke into it as it was sitting outside my friends garage in Reykjavk, will be getting flared fenders and a new painjob..

Too bad they got my DEPO headlights, but this is how it looks like now... already took out that M43 POS:



Car itself:




And here is the glory stuff:


This is a M62B35TU motor, from a 535i E39 i used to own...

I sold the car and still miss it, fully serviced and maintained... next owner pampered it and then sold it on to some prick that treated it like **** and ended up destroying it...

I got the motor from the crash car but the "prick" had already parted out the transmission, flywheel and clutch...

So i will be using a M50 adapter plate and a ZF transmission from a E46 325i, will be rebuilding the transmission prior to install... Clutch is a Stage II of some cheap brand, hope it will hold up...

I have already figured out how to have the throttle actuators work, and i can see where installing the ECU and DME electrics will be easy since the E46 is sharing the same electrics as the E39, electrics will plug in on the drivers side here instead of the passenger side on E39... seems like all the plugs will plug up..

If anyone has swapped a M62TU into a E46... all info would be greatly appreciated...

Oh, and car will get a new paintjob in the coming days...

Reinorange, black top and hood...

custom engine mounts and crossmember are required, so the sump clears the steering rack. use the mounts that the guys who do m62's into e30's and modify your crossmember to suit. i'm 1/4 way through doing this myself. just with the m62b44. you'll want a diff in there as well.
i haven't found a write up for this swap yet, most people think its pointless unless you go s62. but obviously we don't all have the money for that.
try contacting this guy. -

This guy has a M62B44 non TU, and drive by cable....

I am swapping a M62B35TU, drive by wire & some more complicated stuff...

but i've seen this guy around on youtube just never that video...

S62 might go in there later, nobody seems to understand that swapping a M62TU in there will make a S62 swap near plug and play

BUT, i think this M62TU is a "helluva" motor, it would do 13.9 ETs in my E39 back when i had it... and the only mod it had was a M5 differential, came with the 5gang from factory..

in a car that's 300lbs lighter should be interesting... will it put me in M3 territory, that's the question...

and don't forget that V8 grunt...

I already figured how to modify the front subframe, i will have to move the steering rack a bit back, seems like the exhaust will clear as it's a M62TU and not the M62/S62 headers...

I think you guys will like how i solved the motor-mount issue, might fabricate a couple and sell if anyone is interested.... will of course document everything very carefully...

any info for us as to what you are doing mount wise then?

also your 5 looked stunning, shame to hear someone wrecked it, although would you be doing this if they hadn't?

Uhm.. Why not S54, which is already almost 'plug-n-play' and in addition it is more powerful and lighter than M62TU?? Sorry, but it is kinda pointless to swap m62tu into e46.....

I can understand wanting to put an M62 in the car, but I just don't think the 3.5L M62 is a good choice. Depending on the exact model year, its 232-241 hp and 236-254 lb-ft of torque. These numbers are not much better than an M54B30, and for 2 of the 3 possible versions have slightly less or exactly the same hp as a ZHP. Doing a bit more research, the 3.5L M62 appears to weigh about 100lbs more than the M54B30. Given the extra weight the M62 brings to the table, I would doubt its any faster than a 330i, unless you are going to do some work on the engine to get some more power from it. The larger M62's weight only slightly more(~4lbs), but yield a minimum of 60 hp and 90 lb-ft more than an M54B30.

OP, If you have means and will to do it, DO IT.
It would be interesting to see the transformation of a 4 cyl to an 8 cylinder car.
It will have more than twice the power your car originally had. A euro s54 will give you 3 times the power your car was making.
Its all upto you how much work you want to put on it. I like the idea of a v8 though(and you already have the engine).

Good luck.

neither the S54 nor the M54B30 will make the low-end grunt the M62B35TU will make, this is intended as a "mock-up" for a later S62 transformation...

I live in Iceland and it's not that easy to obtain a S54 here, i have this M62TU laying around so why not use it?

I think it's a great way to prepare the car for a BOLT IN S62...

Well then, if the end-game is an S62, by all means, good move.

Actually an S54 makes considerably more torque than the m62B35, and most of it is available from 1500RPM onward.

If S62 swap is your goal, fair enough. Though the latter swap will still require some electrical modifications (probably similar to swapping an s54 into a non-M e46)

365 Nm (269 lbft) @ 4900 for the S54

345 Nm (254 lbft) @ 3800 for the M62B35TU

wish i had the dyno slip for the E39 to post, it did 264hp @ ~5900rpm & 378nm @ ~3900rpm...

and @ 1200rpm, it would be pulling 284nm... don't really see that happening with the S54...

I would really like to see the dyno slip for a stock S54, i think all BMW motors of this era are probably well underrated, a stock M62B44TU with only decats & ECU reflash did a 322hp on a dyno here, but tq numbers were close to stock..

anyway, this is what i'm doing after some very careful planning...

an S62 swap would not be any more complicated into a E46 after a M62TU swap has been done prior....

a S62 will drop right into a E39 540i that had a M62TU, this all comes down to ECU/EWS...

You would even be able to mount an A5S 560Z behind the S62 with some custom ECU flashing

Not from 1200RPM, but from 1500RPM it does pull pretty hard. 284Nm doesn't seem like outside the realm of possibility. Heck with tunes there are a few M3s making 330whp and 260-270 lb-ft at the wheels. I can't find any s54 dynos from 1000, but here's an essentially stock one from 2000: http://www.turnermotorsport.com/imag...dyno_s54m3.jpg

On US software the S54 is dead until 2000RPM. With euro software and headers it pulls nicely from 1500.


MSS52 probably wouldn't take kindly to an automatic. It would take more than a little bit of ECU hacking. SMG may very well be doable since MSS52 is essentially an MSS54 with a couple extra drivers.

You do realize a 3.5L won't be significantly torquier than a 3.2L, right? Cylinder count itself doesn't have a huge impact on torque (hence e60 and e39 m5s making same peak torque). If you were doing a 4.4/4.6 or 5.0 swap, then my opinion would be different.

In any case, good luck with the swap

I did not know the 735i was a V8 with 235 hp. The Transporter makes a lot more sense now.

Also, I REALLY want to see an S62 in an E46. That would be so sick.

The motor i'm using actually came from a 11/2002 E39 i had...





I miss that car every day.... with a M5 diff, it was a BEAST!

I've had a series of BMWs... ranging from E30 325i to E60 530d... and even a couple of M5s.... two E34 M5 and one E39 M5... almost a E60 M5 recently, but the seller pulled out for a better deal but someday...

So as you may understand now, i'm not new to the term POWER...

I will be posting pictures of the new paintjob after new years, i had to obtain a new trunk lid since the burglars destroyed my old one... so painting gets postponed past new-years...

Beleive me, i'd rather have my old 5 than a E46.... the E39 is hands down the best BMW i've had

It had 200.000km on it but it was as tight as new... no sqeaks or rattles, 100% Service book, all had been maintained well...

But i'm looking to do some real cool stuff with the E46...

I'm going to be losing the Sway bar and where the sway-bar used to be there will be motor mounts bolted right up...

You will see soon enough, currently working on making a spacer to use the flywheel off a M54B30 work on the M62B35..
