The S50 isn't laden with unnecessary sensors.. Unless combined with other mods, you won't see much gain in power, the M Power lumps are pretty well mapped from the factoryjimmybob wrote:No problem to map as i have free use of a dyno.
I have no intention of removing the vanos unit, it’s hydraulically controlled and i can take advantage of the cam timing when mapping. Will also be using a knock sensor as this is supported by the DTA
Not that i have looked into wiring the original ecu as i had no intention of using but by the looks of the huge amount of wires and the size of the ecu plug there is a considerable amount of sensors etc. There must be a lot of functions, sensors etc that are redundant when installed in the E30?
As im sure your aware BMW spend an inordinate amount of time mapping the ecu’s. This is done with pure drivability, economy and variance of fuel octanes, fuel qualities etc. As i will be mapping for maximum HP not economy (being able to choose good fuels etc) i would expect anywhere between 10 and 30HP gain.
Not the first time i have mapped an OEM engine with no changes other than the ECU and never failed to gain HP and flatten the torque curve.
I will look into the engine ancillaries i intend to remove and let you know. Haven't started this bit yet.
Like the questions as it's good to re-think options and learn from other. I certainly have plenty to learn about BMW's as it the first time dealing with them.
When it is so easy to wire in the S50 management, spending out on standalone is a waste of money imo..
Good luck with mapping the Vanos also.. It is hydraulic, but it isn't an on off switch like the M50/2 it is constantly variable
got of my lazy arse and made some engine mounts. Some of you may remember that my S14 was sitting on Icehockey pucks (DaveG introduced me to this method).
That was fine for a season but when I removed the S14 I found that one bolt had bend quite a bit and could have snapped if ignored for another season.
So meet Icehockey Engine Mount Version 2
My aim was to make a fairly solid mount and delete the "bolt through" fixing.
Sure I could have just bought a set of AKG mounts but I like making bits. Also have repositioned the engine mount tabs on the subframe to sit parallel to the S50 engine mount face so the AGK mounts would NOT fit anyway.
Looks like this from the inside. I have decided to publish the drawings just in case somebody else thinks these mounts are a good solution and wants to make some aswell.
Single parts with some dimensions. I made the main body from 3" tubing and welded the bottom to it. If you want to machine bits from solid, it's your choice
All the parts lined up for assembly
Inner puck into main body
done
post goes in
done
turned over to show how the post stick out
thin top disk to go in
done. Note how the disk is protruding a tiny bit to keep the inside pack under compression when the top lid goes on.
top lid before welding
ready for welding. The welding of the top disk it the only downside of this design.
I just made a few small tacks and welded only 10-15mm lenth at a time to avoid burning the thin top rubber disk too much. I also used a wet rag to cool things down.
All in all it didn't go as bad as expected, the was hardly any burning rubber smell and the thin rubber disk si anyway not really required for the mount to work. I just added it becaus I had enough icehockey mounts.
Fitted to my subframe. Just needs a lick of paint.

Looking good Uwe. Glad to see you are making progress again. 
Awesome work!!! I'd pay 250 quid for those over the overpriced mass produced AKG things anyway!
Going to have to make some of them for my S54 now me thinks

M42 rightness above 6500rpm, nobody can hear you scream
Cheers man.Took me 7 hrs to make these. But I had to cut all the disks with the angle grinder out of 3mm sheet. The tube is just 3" welded pipe and I turned them a litttle bit out to thin them. Otherwise it gets too heavy.Dave_M3 wrote:Awesome work!!! I'd pay 250 quid for those over the overpriced mass produced AKG things anyway!

Please keep in mind that the mounting tab on E30 subframe is sitting at an ANGLE, so this straight mount will not be a straight fit.
But if you can make one, it should be an easy task of cutting the tab loose bend it up a little and reweld it. Needs reinforcing anyway.
@Jhonno, things are 50/50.....
BTW, I am NOT planning to make more of these. Just too busy with other stuff
yes there is. I am packing up.appletree wrote:Any update on the thread/car Uwe??
was at Brands last week and had passenger laps with Kirby from C3. His M3 is very similar to how mine was. It made me realise that I don't want an M3 with 6 cylinder.
I always like the M3 for what it stands for. Awesome sound from the carbon intake, hard revving 4 cylinder with little torque, vibrations and good handling. I don't care how "slow" it is.
Selling my S14 was probaly the worst thing I could have done. With prices nowadays through the roof for S14 parts it's out of the question to build another S14 from scratch.
I have decided to sell up. EVERYTHING. From shell to suspension, whatever I have with E30 on it.
The Nuerburgring now not possible anymore with the UK insurers not covering even third party I can't see the point of having a lot of money sitting on the drive.
I am taking stuff with me to Gaydon but I am not sure if I can post a list here without a proper for sale advert with pictures etc.
Was a hard decision to make, but life moves on and I have been doing the "M3 thing" for far longer than I thought I would. (12 years!)

I don't know what to say but... 
I feel the same. It's the end of an aera. Let's face it, I haven't driven the car for TWO years. I am ready to move on.billgatese30 wrote:I don't know what to say but...
I have a lot of good memories. Drove it 50k miles+ as a daily driver, we even went on holiday trips doing 2k miles.
Slowly morphed it from a standard M3 into a serious track weapon and mastered the Nuerburgring. Nothing more to achieve really.
Let's hope my shell will find a good home and bring some joy to somebody else.
Anybody looking for a 33k miles S50 with all the bits?
I never thought I'd be reading this Uwe, I've always found your build threads enjoyable and very informative with awesome engineering detail. I'm sure my words have already been said by many.

it's indeed very sad to say goodbye

Truely is a sad day 
Alot of effort and engineering has gone into it, I hope it goes to somebody who will be able to complete it up to standard!

Hi Uwe,
You owned one, you Tracked one, you
modified one, you enjoyed it all,
well most of it.
Many talk the talk, but you walked the walk.
I am at that same crossroads.
Who knows what the future will
bring, and when, but it can never
alter that which has been done, and
in your case, always done very well.
Regards,
The Gorilla.

Nice and very useful thread, truely excellent custom work! To bad your selling. You have a better stamina than me when willing to work outside like that. I wouldn't even consider doing a custom engine swap without standing on a flat surface under the roof..
Many of your pictures of different solutions will go into my "Smart E30 custom mods" - folder
You continental guys tend to have another approach to modding than we see up here i scandinavia. Were you guys modifiy the subframes and chassi we tend to modify the engines (oil sump, exhaust, plenum modding etc..), and using the orginal parts is more whitespread than up here. Thank god for the internet. It just blows the modding scene trough the roof with this sharing of intelligent and smart engineering solutions
This forum truely holds a very high technical standard witch is second to none in the E30 english speaking forum - world.

it wasn't really my first choice of modding the subframe. I just had to pick the task I can manage more easy. Making a new oil sump is for sure something I could carry out but not on a sloped driveway and a £99 welder. So I picked the part which I found easier to work with. Also thought that BMW did a bit more research and testing with the oil sump than I ever could manage. My approch is don't repair it if it works and don't reinvent the wheel
Many of the parts I make are truly based on what I have lying around in the garage or what is in the skip of my friends engineering shop. I do occasionaly BUY materials but only if I deem it absolutley neccessary. I am a tight arse.
Or the plenum. Didn't want to mess with the volumes and flow etc because I can't predict the outcome. Making a manual brake setup, I can!
@everybody else:
I feel very humbled that you rate my little bit of fettling around so high. I am not trying to make something special or stand out, just trying to safe a few ££'s and have the satisfaction of solving a problem myself.
If I would have access to more machinery........(or more money to get stuff CNC'ed haha).
I am NOT having another project waiting. I stop with playing cars. At least for a while. Have some traveling to do and after that I want to build a house. Not just any house of course, I steel framed.
