M50 Developments - considering an M50? Read this.

[Jhonno]

erm i think some 7 series ones are taller..

[buster]

they dont have to be bmw ones like,just as long as they are the right dimensions i'd be happy.

[DanThe]

Sorry for a bit of off topic again. I have another question about wiring. There is a connector on pictures on link. Does anyone know what its for and do i need to do something when puting M50 in ? The pics are not from my car, in my car its just hanging there not connected to anything.

Is it possible that M50 does not start because of this ?

That is the connector for fuel consumption / rpms / speed to and from the ecu,
your ecu will need the kmh signal
your dash will need the rpms signal
your dash will show incorrect mileage so you really donԚ´t need it.

As above, the green wire takes feed from ignition to fuel pump relay, and the other two are for the rpm / mpg gauges. Never noticed myself until I fitted a pre facelift engine into a post facelift body

Hi all,long time no post.
Been too cold lately to do anything but got some work done today.

Heres a few of my e36 rack conversion:





And heres a couple of the Audi master cylinder and golf servo :





Also i decided i wasn't to keen on the e36 engine loom box so i managed after a full day of swearing and screaming to cram all the wiring into an m3 engine wiring cover.I just think it looks better.Heres a couple of pics:





cheers

Great stuff!

How much modification will you require on the inlet side to fit around the servo / master cyl?

I'm trying to work out the most efficient way of doing this, preferably without having to "cut&shut" any of the breathing hardware.

Keep the pics and info coming!

[buster]

unfortunately i did have to cut a small amount from the inlet manifold.
I figured this would be easier and a more cost effective way of doing this without converting it to hydraulic servo.The fitting of the smaller servo meant that only a small amount needed to be cut out.

[randomdave325]

hey buster. long time no speak. no internet at home
yours is lookin sweet now m8! the golf servo fits nice in there. i'm using a 944 one atm. it's more user friendly. i.e girls can drive it without whinging the pedal is too hard!!! but i actually prefered the feel of the golf servo. should work well in yours i think. whats the audi master cylinder off?? 90 coupe isn't it? got no probs with my brakes atm but always up for development
have u driven it yet then? bet it makes a noise

[buster]

hello ,
the audi master was only fitted as its smaller,also its 25mm piston same as the 750 one which m3 owners upgrade to.The bmw ones were to long so the audi one which is an upgrade also shorter to fit.

I have actually fitted a carbon fibre plenum now,makes it even easier to fit.

When's it going to be running Andy ?

Ian.

[buster]

Now then Ian,long time no speak !

Just the exhaust and a few tidy up bits like routing the oil cooler the other side of front cross member,stuff like that.

Actually,i was going to PM you a question.
You know the multi plug that comes off the original oil level sensor in the e36 loom.Can i chop it off and use it to go onto the new oil level sender ?
They both have 3 pins,i know what 2 are,whats the 3rd i need ??

Also,did you use the e36 throttle cable ?,if so what mods are needed to the pedal to make it fit ?

cheers
andy

[buster]

I 've also got one of those boxes from dakota digital.That'll be fun to sort out !

Looking good Andy

Hi Andy,

I'm pretty sure the original E36 oil level sensor plug is compatible with the E34 sensor. Just check to make sure the shape of the plug matches the E34 sensor. Some of those plugs are coded slightly different, but I don't think this is one of them. As for the wires, two are the signal (static & dynamic), and the third wire is a simple GND connection.

I did use the E36 cable, and it fits the E30 pedal just like the original. What is different is the relative length of the inner and outer parts of the cable. I measured it all up and sent it off to speedy cable to shorten the inner part of the cable so that it fitted without modifying any of the bracketry on top of the No5 intake tube. It would be a lot easier to modify the mounting bracket so it fits a bit further back from the throttle linkage though.

Cheers,

Ian.

You only need to give it power & GND, and then splice it into the tacho wire that goes up to the back of the cluster. This is the black wire on pin 7 of the blue cluster plug.

Ian.

[buster]

thanks Ian

The length should be ok as on that carbon airbox,the mount goes ontop of the box so it sits about 2 maybe even 3" further away from the original but as i havent drilled it yet so i can put it anywhere.

cheers

Ian, is this the right ady for speedy cables ?

Speedy Cables, The Mews, St Paul Street, Islington, LONDON N1 7BU Tel. 020 7226 9228

How much do they charge to modify an existing cable or make a custom one up ?

I can't find their web page, do you have the ady for it ?

Thanks

Andy

Sorry for the O/T

Come on Andy, you didn't look very hard

http://www.speedycables.co.uk/

They used to be in London, but have moved to Swansea.

To be honest, I can't rememeber what they charged to modify my cable (also got them to modify the cruise cable as well). It wasn't stupid money, but enough for what they had to do.

Cheers,

Ian.

[Andy335Touring]

Doh ! I should have just stuck co.uk on the end and i'd have had it

I got that ady from a Rally links page i found when i tried to google it.

Thanks for the info

heres a pic :

didnt realise you'd gone CF... whats the fitment round the servo like? still running the golf one?

how much was the CF plenum? looks stunning

[jmc330i]

I think he still has the Golf servo with Audi M/C and it fitted ok, but last I heard he had problems fitting the MAF and air filter in place because the CF plenum is so long.

Does look bloody good though

[buster]

hi guys,
yep james is right,im still with the golf servo and audi master cylinder.
Also correct on the fitment issues.I think i may stick the standard stuff back on and mess with the carbon intake later,or maybe just perservier (sp?) with it. Not sure yet.

Ive got some pics of the clearance etc with that airbox,will upload in a few days hopefully.


cheers

Has anybody used an M20 flywheel and clutch in an E36 box with this conversion? Just wondering what you did with the clutch slave cylinder as mine seems to need a longer pushrod making up for it to reach the release fork

[jmc330i]

I dont think anybody on here has.

Im sure some of the guys in the USA have - Ive read something about the M20 flywheel. Have a look on r3vlimited.com in the "engine and drivetrain" forum.

[DanThe]

Just been reading a few threads on R3V, they seem to all be using the E30 gearboxes
Anybody have any thoughts on this?
As above im using an M20 singlemass flywheel/clutch with an E36 box,
I only noticed this because as I went to bolt in the slave I noticed there was no resistance. Usually you need to press the slave down the length of the studs on the gearbox.
Ive ended up welding about an extra inch onto the end of the pushrod for it to contact the release fork, just for test purposes, if all works fine I will have a longer pushrod turned.
this feels fine 'under foot' but until Ive got the front suspension back on ive no idea how it will feel whilst driving.
Lengthening the pushrod like this means the release fork will not be at 90 degrees to the shaft even though the release bearing will still have full contact on the clutch release forks, its not an ideal situation but can anyone see me having any problems with this?

[Jhonno]

the oil return fitting from the s50 sump.. can anyone tell me what size hole needs to be drilled and tapped into the e34 m50 sump (being lazy rather than measure myself )

[buster]

i think it was m12x1.5 Not the standard m12x1.75.
Measure it !!

Andy

that carbon plenum is porn, pure porn

how long until this beast is on the road then?

[buster]

Hi lee,
it starts and runs and can move under its own power,but exhaust needs doing now.Next week im handing the car over to someone i know to modify the manifolds as its way beyond my welding and pipe bending skills.
I also need to put in a higher pressure fuel pump.

And thats it !
Getting very close although i may have to put the standard airbox back on if i cant connect the MAF sensor up.
Thats the other job i need to do.

Get him to do me one too!

Great project!

Couple of questions:
1. Do you know where I can buy an M Power valve cover?
2. Which Golf and Audi models did the servo and M/C come off?

Cheers

Sorted my clutch problem out,
the gearbox had an E30 slave in it
This is the difference \/ E30 on the left / E36 on the right
