SL129 disks. I use ECP, BREMBO. Offset doesn't change. Will dig the part code out later

When I used them first they where listed as E500 but for some strange reason they are not listed anymore. The later E500 has larger disks, whatch out. I have a drawing of the modified disk.
What calipers do you have? You know that they need some slight milling as well?

I made a writeup on e30.de, look here http://wp1016621.wp027.webpack.hosteuro ... f00464.htm

Thu Apr 23, 2009 9:16 am

yeah i can mill them at work, but i also have a set of brembo 4 pots which suit a 28mm wide disk so i may use them if i have enough clearance.
I've looked on ECP but cant find them. What year and model exactly ?

Thu Apr 23, 2009 9:40 am

They are M60163. Very interested to see your brembos! I was thinking along those lines as well.

EDIT
oops just realised, I bought the disks at German and Swedish
But ask for the BREMBO disks, otherwise you just can any other make

129: SL320 V6 112.943 06/98>08/01

Thu Apr 23, 2009 10:05 am

heres a picture.They are standard fiat coupe turbo fitment.Got them brand new for £400 i think.

Thu Apr 23, 2009 10:52 am

hmmmm, they are lug mounted. I was thinking of getting some Porsche Boxter radial mounted.
Some Boxter run a 302x28mm disk and if I can get the caliper to fit behind my wheels I would keep the Merc disk. I am quite happy with the brakes (so far......) and they are a very cost effective solution. Have done a whole season at the Ring (approx 1500kms) with ROADPADS and the disk are still good for another season. I would first upgrade the pad before fitting larger disks to be honest. Worth a trial (with the 300mm disk already I am talking)

Hi Uwe,

Glad to see you're making (very good

) progress.

Cheers,

Ian.

very good progress, you are kidding me. My engine bay is still empty

today I found out that the "german" version of the wiring harness has the ECU plug on the correct side of the E30's ECU location. No wire fiddling/re-routing required!
I am not looking forward to the electrical bit, it may be all easy to you guys but I rather cut an engine block in half and weld it back together. Seems much more easy to me

PS was already hunting for a wiring loom on german Ebay and loads of looms for sale. Guess what? They are all from RHD cars....

My S50 is also from a ZM, I believe they have the ECU mounted in the same place as an E30 but if the S50 is from an E36 then its mounted above the glovebox.....

Excellent fabrication skills there btw! And tell us more about your brake mod please?

nothing special with the brakes. Just the usual E32-735 caliper and Merc disk swap. Or use E34 540 caliper.
Has worked fine for me so far.

My ZM loom has the ECU plug on the wron side and I have been told that the fuel relais is missing as well, part of the ZM car loom. How did you wire yours?

hello uwe,
it looks to me like the fuel rail is there, but the plastic rail that holds the injector plugs is missing? it also holds a few other wires and plugs, as it looks like your tps only has a short loom on it and the plug is hanging down ?

sorry but I am a bit lost. There is NO loom on the engine at all.

Fri Apr 24, 2009 9:23 am

i can see the fuel rail in this pic

the fuel rail, yes. But not the plastic channel with the plugs. That's dangling on the loom lying in my garage.

picture of the ECU plug and the relais. Have been told that the fuel relais is missing on the ZM loom

Fri Apr 24, 2009 10:10 am

my mistake.
( note to self.....must learn to read slower

)
i read 'relais'
i thought i read 'rails'
lol!

Brave man Uwe doing that on your drive! I've walked up and down it.. Not a gentle slope either! think Billy Kart start ramp!

please can you tell me what you have done with your brake servo and master cylinder thanks

Sat Apr 25, 2009 1:06 am

can't tell you wayne , top secret

Sat Apr 25, 2009 1:36 am

hey buster dont mean to go off topic but what wheels are on your car and if their five stud what setup did you us for example 318ti compact rear or what sorry and thanks

Sat Apr 25, 2009 3:45 am

8 series wheels ,5 stud, e30 m3

Sat Apr 25, 2009 5:39 pm

The ZM loom that came with my engine (from a RHD ZMRoadster 1997built) was almost perfect for the E30 engine bay. The ECU wires are all long enough to mount tidily in the standard E30 position and if you wanted to keep the E36 style wiring cover there's very little you'd have to do. As it goes I am fitting it all into an E30 4 pot wiring cover which makes it a bit more of a pain in the rectum but hey-ho.

The relay for the fuel pump is indeed in the car loom, not the engine loom but that was a piece of pee pee to re-wire in the engine loom. I've not yet wired in my EWS circuit into the car so am yet to see if the thing starts. Nearly there but I'm out of money and working a new job up in the midlands so progress is slow.

Good to see your swap coming along Uwe. Very impressive, though you should stop worrying and slap it in there.. Bit of old string and a jack should be all you need to drop the engine in...

Sat Apr 25, 2009 9:14 pm

I used E34 M5 booster and mastercylinder,, 25 mm vs 23 on M3

((I have the E30 M3 wheelconversion and the brakes are fantastic with the 25 mm master

))

Sat Apr 25, 2009 10:53 pm

got a bit or work done today.

one I prepared earlier. Modified bonnet hinge to a quick release design. Make life much more easy. Bonnet can be taken on and off without messing with the bonnet alignment

note silver pin

take pins out and bonnet is off

ready to start work

first careful lift

and up it goes!

strange view that is

I also found a way to get the engine back up the drive

engine wheeled in

and a well earned break!

I am quite please with the function of the lifting gear. Everything worked smooth and the car was always stable.

Sat Apr 25, 2009 11:30 pm

You were right! It did work well..

Sun Apr 26, 2009 3:10 am

I once tried to push my s50 half a mile up the road on machine mart castors.. Naturally they broke so me and two others dragged it through Coventry and lifted it into my student front room. They are HEAVY.. lol

Bonnet releases?? Me WANT....

very easy to make. I used to M10 Stainless Steel bolts (no need to use a bolt but that was the only SS I could find

)

just grind one side of the hollow BMW pins off and drive it out. Replace with SS bolt and secure bolt with cotter pin. I want to replace the cotter pin with some R-shape pins later.

Don't forget to disconnect the gas lift thingy before you try to walk away with the boonet

Hi,

Uwe- Your firmly converted to the dark side now !!!

Can you feel the Force.

Looks like you got this all sorted.

Brings back a few memories, sloping drive,
fresh air, tea breaks, good light, rain,
wind, moaning neighbours ...........

Once this is all complete you will wonder
why you did not do it sooner.

Compbrake now do a nice remote servo for
those interested.

Regards,

The Gorilla.

G,
what do you mean with remote servo? Now after I am finished with my servo mods.....

Sun Apr 26, 2009 1:41 pm

Damn good idea..

I have a carbon bonnet and dont really want to leave it on all the time. I shall be living in Coventry soon where people are slightly less desirable than round these parts... I think I might have some stainless bar around here somewhere too that looks like it'll be the right diameter!

Sun Apr 26, 2009 2:17 pm

Hi,

Uwe- their new Brochure only arrived this week.

If you go to www.compbrake.co.uk you will see
that they are now doing a remote servo.

Its not cheap, and with all your skills I am
sure you have done a good job, for a lot less.

The Gorilla.
