117 kg for m20
152 kg for s50

What weighs about 35 kg just to give an example of how much heavier it is ??

What rad are all you twin cammers using then ??

Ian,
the pump at the bottom ,is that what your using ?

What rad are all you twin cammers using then ??

I'm using the E36 Evo radiator. It fit's a treat, you just need to change the passengers side plastic mounting foot (pence at the dealer) for a shorter one.

Cheers,

Ian.

The e36 i got mine from only had a 325 rad,it was same as mine

Do you think e28 525 one will fit,its just longer than the e30 one i think

[Andy335Touring]

What weighs about 35 kg just to give an example of how much heavier it is ??

An E30 dif weighs 38-40 kg and a 325 gear box is 34kg.

I don't know how it compairs size wise with the Evo rad but the E28 535 rad that i'm using is a decent size and a fairly easy fitment.

The core of my rad is 35mm x 470mm x 570mm

[buster]

nice one thanks andy,theres one on flee bay now for a 535,i will have a bid on it i think

[jmc330i]

Ive got the rad from an E30 325i that has air con.
Same width as a normal E30 rad, but is taller. I then modified the plastic surround so the the air flow can get to all of the rad.

Would have used the S50 rad but it was damaged.

[Andy325i]

What rad are all you twin cammers using then ??

E30 325i 1990

[Brianmoooore]

I'm using standard E30 325 rad as well. E34 looks like it would go in, with the extra space freed up by not having an oil cooler, but I don't see why the M50 would need any more cooling than the M20.

Andy,

Yeah, the bottom one looks about right. Infact, the top one (E36 M50/S50 ?) is probably the pump I used, but with the pickup pipe from the lower one. It's all fairly mix 'n' match.

I'm not sure if the e28 rad will fit, but I suspect it will. BMW are really good at keeping sizes standard across models/years.

Cheers,

Ian.

[Jhonno]

whats the smallest servo out of the 19 16v/Golf/Porker? Any pics of the spacers made up to get it to fit?

[buster]

i think the 944 is a direct replacement.

[Jhonno]

how are you doing it fella?

[buster]

im thinking of fitting the 944 one and see how much room i have.Then if i have to move it down on the firewall.Mod the airbox possibly.

[Andy335Touring]

If any one is struggling to get a 944 servo theres a Porsche breakers just down the road from me,i'll pop over and see if they have any in stock if any one wants me to ?

[randomdave325]

hello again people.. after working long in to the night. mine is finally up and rockin 2 nite. after clutch issues, leaky water pump and stuck thermostat it moved under it's own 2.5 power! first drive impressiions were that it was way quicker before but i spose it was a hartge h26 and now it's just standard bm again.. but sounds nice and it's good to have it back. the gearing is amusing but sits nicely at 80 and is way better on fuel than before. 80 to 125 is impressive. but then thats it. limiiter in 5th. no more. which is gonna be poor at the nurburg. but will do for now. i'm using 92 e36 325 rad. on 2 o/s mounts. i think it need to be higher as is a mission to get the air out of the matrix as i's a bit lower i think. but just teething troubles. it's only been going 3 hrs. i'll jack the front up on the ramp and bleed it again 2mo. intermittant heater is annoying.. i' use the mk 2 golf servo in the end. 944 one the rod is too long so u have to tap the thread and shorten it before it will fit. golf servo is fine i adjusted the brake pedal up a bit and it's been spot on so far. i'll fit the porsche one at a later date. got to go to bed now as am driving to run to the sun in newquay tommorrow for the test drive and a long weekend. if anyones down there and see's a rough dirty black bm with a hartge badge and red leather. come check it out init. i'll let u know how it goes. wish me luck

[Andy335Touring]

Try swapping the heater pipes around where they attach to the bulk head in the engine bay.I got mine the wronge way round and got no heat if the revs went over 1500rpm.

[Toby_Unna]

then i did the same thing and only found out when Andy suggested it! good information mate!

[Andy335Touring]

I got the info from Ian332

see you there! albeit in me van

[buster]

so the mk 2 golf one is a direct replacement then ,not the 944 one ?

[Andy325i]

The Mk 2 one needs a spacer rod as the rod in the servo itself is too short as it is

I think its about 8 mm long (CHECK THIS!)



This is what I have so far, it needs cutting down and shaping before I fit it though

[buster]

thing is though andy,the 944 one looks smaller.All that is needed is to shorten the rod ?

[Andy325i]

For the Mk2 one? will let you know on monday as I will be doing it then, but I think the bit of rod is the only mod

Andy

[buster]

Ian.
heres what i removed form the car regading the EWS system.

I hope i have chopped out what i needed,the key was taped to the ring.The light in the key still works !!!!





Do i have what is needed now ??

[ian332isport]

Hi Andy,

Sorry I missed your call last night. I have really dodgy mobile coverage in my house, and did not get your message until I popped into the garage later in the evening.

Looking at your pictures, it would appear that you got everything you need to wire in the EWS system

I know it looks like a lot of wires, but you don't actually need to connect that many of them. I have full details of this, so let me know when you need the info, and I'll sort you out with the relevant details.

Cheers,

Ian.

[buster]

hi Ian,thanks for taking a look.I thought id give you a buzz as i was sat in the stripped out car with snips in my hand ! Was a bit unsure because i thought i would have to take whole loom out but i remember you saying cut and leave plenty of wire on so i assumed i must cut them out of the car and not take the lot.
Also i asked the guy who did the conversion and he said that it was running the 325 fuel pump so i didn't bother getting it.I will have to accuire one later.

[buster]

hi guys,
Engine and box are in,as you know.The gearbox mount needs making yet like,its just secured with a metal brace for now.Thing is everytime i take the bonnet off,i dont know where to start

[jmc330i]

Thing is everytime i take the bonnet off,i dont know where to start

I remember that feeling

Are you using the 6spd or 5spd gearbox?

[randomdave325]

hello. unfortunately. my car didn't get to newquay. i had to go in a fiesta van. not so much fun but only cost a fiver. the car didn't actually break. i just wasn't happy with the air in the cooling system problem and didn't want to risk it. i've just checked the heater matix pipes and mine are the one from the back of the head in the top and the one to the rad on the bottom. i'm pretty sure thats the way they go. is there any chance someone could have a look and verify this. it's a mission to just swap them over. i have to remove the engine mounts to get in there as it's a bit tight. buster. the golf servo is the smaller one out of the two. i've done 200miles with it now and am well happy with it. just cooling to sort out and i'll get the pics and full explaination on here. all at home atm.

[Andy325i]

Hi mate, did you have any luck with that scappy in exeter?

Cheers


Andy

[6potWil6pot]

The rad in mine was from an E36 with no aircon, i know this because i even changed it (one of the only mechanical things ive done )

Maybe the car i had was freshly built but the brakes (944 servo) it had were very good, better than a lot of cars ive driven; better than the Puma which needs more effort and the ABS is too keen to chip in. Although the pedal had the play you get in all rhd E30s, once you past those few mm it was very good.

[buster]

jmc330i
Im using the 6 speed which came with the engine.

Reardiffraver,
Wise choice,i wouldn't have risked it until its all right,dont want it boiling over 100 miles away.
The golf servo is smaller diameter than the 944 one ?
Also i think you may have the heater pipes wrong,im pretty sure the return to the rad should be at the top hose as i think they flow through from bottom to top,maybe to eliminate air locks

[jmc330i]

jmc330i

Cool, it was just me getting confused then.
For some reason I thought you had a 5spd and was trying to figure out why you were making a gearbox mount.

On the S50, the bottom heater pipe is the inlet, and goes to the cylinder head, so I would guess its the same on the M50.

[randomdave325]

cheers lads. i swapped them over and have permanant heating now. it's still getting hot but i just keep bleeding it randomly and should be ok i reckon. it runs between 1/2 and 3/4 on the gauge. it used to run on 1/4. but i'll get to the bottom of it eventually
for the record anyone doing this conversion leave the standard diff in when you first do it. it pulls from 20mph in 5th now which is amusing. with the gearing it would make an excellent track car. whens the next meet? everyone will have to have a play in it and see what you think. it's worth it for the noise alone. i'll post some finished pics when i get chance. thanks again .
andy. i haven't had chance to get that loom yet. theres no keys for the vehicle. is is still any good to you?
buster. use a 1.3 golf servo m8 if you havent already bought a 944 one. as they are well cheap, fits spot on and works fine. just make the pedal higher and they are as good if not better than standard. u can do this with the spacer between the servo pushrod and the master cylinder. just cut down a 8mm boly and put it in between to work out the measurement. should stop it no probs. even with another 120bhp

[jmc330i]

Yeah Im looking forward to driving mine with the 3.91LSD and the 1:1 5th gear untill I get the M3 diff sorted.
Should be a laugh for a little bit.
