The antidote to bloated M Cars, My 2000 S50 M Coupe
Discussion
Pleased to say that I've managed to acquire one of the cars on my "list"
I've just sold my 1996 TVR Griffith 500 and replaced it with an Estoril Blue S50 BMW M Coupe or Z3M Coupe.
I've had her about a month now and no regrets so far.
It's exactly what I was looking for, something cool and quirky, fun to drive and yet usable.
She's just coming up to 20 years old with 88k miles on, a few bits and pieces to tidy but generally in fine fettle and with a huge amount of service history.
First few things have been a set of new Michelin PS4 Tyres to replace the 9 year old tyres that the car came with, and fitting a new throttle cable which seems to have liberated about 40bhp as the old one was stretched and not giving WOT, £60 well spent on that!
I absolutely love driving it, cable throttle, no TC and it feels light and direct.
Coming from the TVR and before that a Maserati 3200 it also feels re assuringly well put together!
Maybe controversial but I think this car reminds me how good BMW M were for a pure driving machine, current M cars just don't really appeal to me.
My DD is a Alfa Giulia Quadrifoglio which sits alongside a 1966 Alfa Giulia so the M Coupe seems like the perfect in-between usable modern classic for me to enjoy. I can see why many cars have a good number of miles on.
Need to get some pictures sorted soon
Other plans are perhaps a Hayward and Scott rear exhaust system, and maybe sports cats with an X Pipe.
Supersprint exhausts are another consideration but I've heard they lean towards being too quiet and also seem to come at quite a price.
I currently have AC Schnitzer rear boxes, something I wasn't keen on although the look has grown on me, have to say though prefer the 4 pipe staggered look to the twin Schnitzer pipes that look a bit like they belong on an SR Nova
Also going to remove the clutch delay valve and consider fitting H&R anti roll bars which seem to be well regarded.

Nice, do miss mine. I had H&S exhaust on my car along with Evolve Carbon Airbox, sounded amazing.

Thanks, did you sell to a guy in Scotland? I was talking to him about his highly modded car, sounded interesting.Get over on https://www.z3mcoupe.com/forum/forumdisplay.php?f=...
Carbon airbox is tempting although Evolve apparently won't map a S50 anymore, only person in the UK is Wayne at Chipwizards apparently.
I'm also a bit unsure about going for Alpha N as I've read it can be bad at part throttle/not as drivable as you lose the MAF.
Trying to mod her but without compromising usability

Ah right where did you talk to him, he was from up north somewhere had to get a boat or something and trek all the way down to me. His dad came with his Lotus Carlton!

I had it repainted in Interlagos Blue. Don't think he has done many miles since I sold it to him. I've only got back in a BMW since selling it a low miler LCI M6 V10 which wont be going anywhere for a long time lol
Keep eye on German ebay for a nice carbon box, I am sure someone can map it. Try BWChiptune and EndTuning, he used to be on BMWOwner.com/E36Forum when I had my E36 and knows his stuff.

Thanks for the positive comments guys!
Still enjoying driving her about inc including picking up the Turkey and wine shopping yesterday, the pratical hatch etc.
Then somewhat amusingly I picked up my 89 year old Granny and took her to church this morning her comment "you like the sound of the engine in this one then" after extending it briefly. She also appreciated the heated seat.
So fun but so usable so far.

I had one of these for a couple of years, interesting car, found it practical too (had the BMW rack for my bikes and took it camping) but its still a bit bloated, no? Not exactly light. Think mine (with sunroof) was over 1460kg.
Fair comment, but it feels lighter on it's feet than the weight suggests. The S50 engine is a cast iron block and then I guess adding a roof to a roadster means you have the extra bracing weight of the roadster plus the roof.
For the first few days I struggled to park the thing properly, it's so short in length seemingly and yet with wide hips!
Your car is stunning OP.
If a Z3M Coupe had been in budget I might have been sorely tempted, but as it wasn't I ended up buying a Z4M Coupe a couple of weeks ago.
It doesn't feel bloated, although according to BMW it's 1,495kg. Still with an S54 engine it gets going pretty well!
Looks like you have started your project around the same time as me. I'll be looking out for updates.

I was tempted by a Z4M too but I stretched to get a Z3M as I just love the old school charm.
The lure of the S54 and the way the Z4M looks from behind were a temptation!
I'll try and update things as I go along
Jobs Done So Far:
- 4 New Michelin Pilot Sport Tyres
- New Genuine Gearknob to replace the slightly worn old one(love how the M logo lights up on these)
- New Throttle Cable to replace the old stretched one gaining seemingly 30-40bhp.
- Changed the Gearbox oil and it now goes into reverse a lot easier and the shift is a bit smoother. Filled with Amsoil MTF Fluid.
- Replaced the Viscous fan clutch as it was on its way out with signs of play/vibration and didn't have much sign of drag from cold.
- Change all aircon and aux belts, along with hydraulic belt tensioner and all idler pulleys (the existing ones have an intermitant squeak). Have ordered a full set of Gates Tensioners and belts.
- Replace worn seat bushings, a common fault on these. The seats rock back and forth under heavy acceleration or braking. Only £12 worth of bushing parts to fit, but seats have to come out.
- Fit braided clutch line that removes the clutch delay valve, gives a more natural feel to the gearshift I'm told.
- Rear wiper activates but doesn't work, need to investigate.
- order and fit H&R anti roll bars
- order and fit different rear exhaust boxes (probably) and or X pipe.
- perform Vanos diagnostic check with emulated BMW DIS software, have ordered lead and software.
- take sill cover and wheel arch liners off to double check for corrosion. (!)
A few smaller jobs ticked off the list this weekend.
Changed the Gearbox oil for Amsoil MTF fluid, it seems to go into reverse easier now and the changes are slightly smoother.
More of an improvement was replacing every tensioner and bearing in the aux belt and air con belt, these were pretty noisy. You could tell they were we past best as the one ones spun more freely and had a gritty feeing.
I also replaced the Power Steering pump pulley as someone had damaged the edges of it, no doubt when fitting a new pump.
Also check for play in the water pump, seemed to be next to none. Plan to change the pump and thermostat along with a few hoses in the near future as preventative maintenance.
Ordered a full set from Gates which to me seem every bit as good as what you buy from BMW at a more sensible price.

Some good progress made then!
But as a serial BMW owner I would expect the gearchange to get even better once you've removed the CDV.
Yup need to get on and do that. I've soaked the hose ends in plus gas penetrating fluid, always a bit scary undoing brake or clutch hose ferrules on a 20 year old car! Never enjoy bleeding stuff either... Should be simple enough hopefully, keen to try it as sometimes I've felt my gear change was fine but I was just a bit too quick and the clutch came back in slowly...But as a serial BMW owner I would expect the gearchange to get even better once you've removed the CDV.
Got to consider my exhaust options too.
Supersprint, Eiesmann or Hayward and Scott.
Think I might ask Hayward and Scott for a set of their back boxes but also ask them to fab up an X pipe to replace the standard H pipe.
I also tried a Simota induction kit (like a gruppe M) but quickly took that off and re-fitted the stock airbox. The car felt like it lost torque and didn't run as well, slightly free-er at the top end but not worth it. The deciding factor was that the induction sound i hoped I'd get wasn't really there, obviously not a patch on the full carbon airbox route, but i'm also not sure about that because it's a lot of money and then it means an Alpha N remap which can mean it's not so good a part throttle and might struggle to pass emissions tests.
Trying to make subtle improvements and keep her mostly standard.
