S50B32 engine in Z1

Post by M3rwin »

I'm swapping my m20 turbo engine for an s50b32 m3 engine.
Tried to fit the m3 engine today but ran into some problems with the oil sump and engine mounts.
Does somebody know what kind of modifications i need to make to fit the s50b32 in my Z1 ???
Hope somebody can help me out which oil sump and engine mounts i need to use!

Senna is the man you need to speak with, he can get a lorry engine into a Z1 if he tried :wink:

Hope the house warming party went OK

Post by Bruno »

Hi Guys,

I received your email and I understand your problem, but the only Expert is Mister Senna !!
I’m so sorry but I cannot help you, but I am very interested in your issue !! For sure !!
You have to contact Senna on this website !!
But how much have pay your s50b32 m3 engine ??
Because I would like to make the same conversion but with Senna, not alone, it’s necessary !!
And I would like to known if Senna is still available this autumn/winter to make this conversion ??

Bruno, Will keep you up to date!
Got an e-mail back today from Senna, he told me to ask Apollo because he owns his car now and has all the technical info. Sended him a PM immediatly, hope he has the answers for me so I can continue with the project!
I paid 2K for the engine on eBay germany complete with all the parts I needed such as, ecu, ews with keys, wiring loom, starter, manifolds.
Refurbished THE engine for € 500,- put new bearings, chain tensioner, and all THE gaskets in and it's new again.
Just one issue left, install it !

I will keep my fingers crossed that it will work out fine. There also seems to be a guy in Germany who does these M3 engine conversions in Z1's! I will see if I can get his name for you.

Further I agree with Bruno. Could you make a diary of the conversion including pics. Should be very interesting for the forum members!


Good luck with the conversion,

HH

M3 Conversion

Post by Bruno »

Hi Guys,

Congratulation Erwin !! Yes Yes please put online all pictures of your M3 Conversion !! Your photos are great !!
Because many people and me are very interested !! I would like to fit on a M3 engine too !!
I known that it's a quite hard conversion, you will have some problems with the cooling system, because there is much more heat under the bonnet with your M3 engine. So you have to add a cooling system oil too and so on...
Tomorrow I'll check up every problem that you could be have !!

Bye bye and thank you !!

Hi Erwin,

Nice to read about your new project!

Like most things you can do this only two ways, the wrong way and the right way.

I saw a lot of wrong one's. In Germany a month ago a z1 one who was converted by Kelleners, a German tuner. It did not look nice. The engine was building very high and not mounted straight. The adjusment form the fan and the airbox did not look nice either.

I know the German guy Harry told about, he did it the right way but is very secretive about it.
Look at the German forum at E30.de a lot of guys did it there for the e30. You will find a lot af knowledge there. also Timi from 300MM.de will be able to help.

Suc6 and keep us posted.

A real shame as all the other forums I use people go out of their way to help each by sharing useful information!

I was looking at the M52 or M54 328 conversion as my E46 is a 2.5 M54 and it is so much more powerful than the old M20

Good luck with your conversion, and please do share any information you find. :)

I am in agreement with you on this one, I think Senna is a W****R also, maybe be has a small penis and hides it behind his knowledge of Z1's. He is away for a week so i will edit this thread before he gets back :shock: :shock: :shock:

Happy New Year Apollo! 8-)

Hope we will meet this year? I think if Senna isn't willing to share his knowledge than that is up to him. He put a lot of effort and money into fidding al bits and pieces how to do it. Normally I am for sharing things and knowledge. Apart from my Z1 and my wife! :twisted: But in this case I find it different. If you want a other engine. Call Franz Schaffer for a M20 3.0l or call Senna to fit in a 3.2l M3 engine. Both guys you have to pay and both invested a lot of time and money to get this far. Also the erman guy who makes the M3 3.2l conversion is not willing to share his knowledge. You want an engine of one of these guys? Pay the price!!!! :roll: There isn't always a cheap way! :cry: Only the do it yourself way but than al the way.

So I understand Senna's position on this one. Franz Schaffer has the same as is the other German who does M3 conversions.

M3 Conversion

Post by Bruno »

Hi Guys,

I wish you a Happy New Year !!

Currently I'm talking about that with Senna for sure !!
(fist of all we are going to make the white conversion rear light before with my French Supplier)

And to make this quite hard conversion, I think it's very important to make the better choice !!
So I would like to fit on a 6 speed gear box !! Because I think that would be a pleasure on highway and for sportivity driving too !!

Greetings

Err..... Re Senna's penis: It may not be that small after all, as his knowledge of Z1's is considerable and therefore lots could be hidden behind it!

Guys. You may think that I am a terrible person, I don't share my knowledge, I am not part of the forum.
BUT:
a)I owe it to those that have paid me for their conversions to maintain confidentiality, they have paid a lot of money to have work done.
b)I have never asked for help or parts from anybody and spent tens of thousands at BMW for the parts and not expected them for nothing.
c)Hartge/AC/Alpina do not give out these details.
d)If you want a conversion, give me the car, wait a bit, pay and I will return it. (not at the moment though/exams and family come first)

Senna, please do not take this as a personal attack on yourself; I was merely saying there are people on the forum with the knowledge of what fits and what does not, as it would save poor people like me wasting hundreds of pounds trying in vain when the time comes to convert.

I would love for you to convert my car for something with a little more power(but not the M3 beast lol), but the only problem I have with that apart from the finances is I own a Z1 for pleasure and a hobby and I take great pleasure in doing everything myself rather than taking it to a garage.

Now if you were to offer an engine and gearbox kit, that’s if the gearbox would actually need changing! Then that could be something I could live with as I would be fitting it myself
Anyway, when are you coming on tour? As I have just read the book on mastering the art of Japanese water torture :D :D

M3 Conversion

Post by Bruno »

Hey Guys

Keep cool my freinds, I just asked some advices for this conversion !!
I just would like to find the best arrangement to make this conversion !!
I known the price is not so expansive because there are an engine + gear box + time of work + knowledge, but it’s just quite expansive for me !!
So maybe I could propose to have the same interior like my Z1 and hope to find an arrangement !!
I found a new job, it’s really great and I started the 3 of January, as an engineer in Automotive Industry for Peugeot-Citroën in Reseach Engine Department, it’s close to Paris in France.
My god Yes I kept my Z1 !! I could work with you on my conversion at the weekend for example, but you are so far away, so I must leave my car for few months, it’s not a problem, it’s just quite expansive for me !!
Because I have no work shop, no M3 engine, no gear box and I think I have some good skills but I haven’t got your knowledge to make this convertion alone !!
That’s it !!
Maybe I never could make this conversion what's a pity !!

Hi Guys,

This Z1 powered by is very nice for sure !!
But it must just change the « orange part light » to « white part light » and the same thing for the front light !! That’s all !! :)

For my Z1, it must have just a Motosport Engine that’s it !!

Hi Guys,

The BMW M Z1 Roadster

Post by benslick »

The BMW M Z1 Roadster

BMW only produced four BMW Motorsport Z1 test cars which they never publicized or released.
The motorsport Z1 looks completely as standard with original steering wheel, gear knob and alloy wheels.
However, the car has a completely different stance from the standard Z1 because of its M Technic suspension.
It was also fitted with E30 M3 steering rubbers which is a popular upgrade today.
The M Z1 has an M20-based motorsport 2.9L engine with a limited slip
differential, both developed by the M Technic team.
All four of the M Z1s are owned by BMW staff, one being the chief technician of BMW motorsport maintenance department.
His car is a Fun Yellow Z1 with 225 BHP.
The M Z1 also has far more torque than the standard car.
Franz Schaffer obtained the very last set of M tech suspension for his own Z1 from the BMW motorsport team, which he has close links with.
The next time you come across an M badged Z1, you never know, it may be one of the four.

Hi guys,

It's bin a while since a last update of the project, had some busy times last months. Work work work, and my girfriend is pregnant!!!
Expecting our daughter around the 1st of august so I put a lot of effort in the baby room and all the other things that come along with it so I lost a bit of the focus on the car.
But finally last month I picked up where I left and already did a lot of work again on the engine conversion.
Engine is finally in place now under the right angle with the original m3 engine brackets on the standard Z1 enigne rubber mounts it clears the bonnet perfect by 2 centimeters, unfortunatly had to mount an oil sump with pump from a 3.0 e36 m3 which not has the dual oil pick up which is worse for heavy circuit driving, but for street driving will be perfect.
I needed to mount the 3.0 sump to clear the steering rack which also now has repositioned mounting brackets to clear the oil sump.
To clear the airbox it was neccesary to fit a smaller brake booster, after a long search I found the booster of a new model fiat punto which has the exact same offset and mounting positions of the original but was precisely the 3 centimeters smaller that I needed. Only adjustment I had to make was shorten the push rod and cut some new thread on it. As you can see on the picture below it fits perfect.
Then it was time to do some wiring and electrics, my favorite part! I found someone who was able the reprogram the m3 ecu and he erased the EWS system so i didn't had to make and extra wiring loom for it and could ditch the transponder key. He also erased the rev limiter and the need for a speed signal.
Connect the wiring of the m3 engine to the Z1 electrical system was a bit nasty because there are 2 different connectors on both sides, I cut the one on the harness of the engine and connected a similar one but the opposite of the car to the harness. With original bmw wiring diagrams it was easy to do.
This week I have the intention to do all the plumbing and fit the oil cooler and continue the work on the gearbox/torque tube connection which still is the most challeging part of the project. My main goal is to fit the engine with the torque tube to have all the benifits of this construction!
For this i'm using the 5 speed 3.0 m3 gearbox because it has the same length as the Z1 box and I don't neccesarily need a 6th gear because in the 3.2 6 speed gearbox the 6th gear is just an overdrive for relaxed driving, and that's not what I intend to do with it!
So far I mocked up the whole construction on a workbench. This week will start fabricating an adapter plate for mounting the tube to the gearbox, will post some pictures as soon as possible. As soon this part of construction is finished the end will be near, then only need to attache the nouvalari exhaust to the m3 engine for a screamy sound and some small things.
Unfortunatly it will be impossible to get the car ready before the tour at the end of this month, so we take dad's yellow one!
That was it so far, keep you up to date!

Erwin,

Shame we wont see the finished article, but keep those original pictures of the build, I would like to do a feature of the conversion in the magazine we talked about, would make an interesting read. Good luck and see you soon.

M3 Conversion

Post by Bruno »

Hi guys,

When I read this article I say myself that the reason why I will have to make this conversion with some experts like you !!
Great Job really !!...

According me the 6 speed gearbox would be great to decrease the comsumption of gas !!
That depend if we drive on the long way, for example I wish to go to South of France (Cannes, Monaco) so it's quite expensive !!

But Currently I'm studing some technical questions about DKG Gearbox with a 6 cylinders !!

Hi, I'm currently putting a 330 engine & manual box in my wife's Z1 and as has been indicated by others it's difficult to get people to share information on this site. Can anybody please suggest some sites where I am likely to get a response. Thanks.

Hi Mike,

First of all, your Project would be very intresting !!
I'm so sorry but I cannot help you on this item, because I would like to fit on my Z1 a powertrain [Engine + DKG Gearbox] too and anybody have made that yet !!
There is an expert in the website Zroadster, about Engine Conversion for Z1, his pseudo is Senna (like the Famous F1 Driver) !!

I contacted him several times for my Project, he still is available to answer to technical questions, but for my case I don't have yet this budget to make this conversion !!
But for your conversion, you can contact him as soon as possible on the website Zroadster.

Hi there,

I kickstarted the M3 conversion project last month again ! Couldn't found any time for the project first half of this year due to a very busy schedule I had with Audi Sport and my little daughter !
But finally all the pieces seem to fit together, the 3.2 M3 engine is in place with M3 5-speed ZF transmission with a unique bolt on structure to fit the Z1's famous torque tube to maintain all the benefits of the torque tube drivetrain.
Cooling system is ready, pre fitted the air box and intake system also ready, now last but not least have to finish the exhaust system. I'm going to use original M3 exhaust manifolds and a nouvalari rear silencer, have to make a complete new middle section with motorsport catalytic converters.
Keep you updated

Here a link to a you tube clip of the Initial start of the M3 engine in the Z1 last week!
