CSL v's M3 - Exact part differences needed!!

[Craig]

Hi folks,

This is maybe one for the CSL guru guy's, I need to know EVERY difference between the CSL and a normal M3. I'm talking everything, wiring looms, etc.

I know the following are different;

- Plastic Boot
- Carbon Roof
- Front Bumper
- Rear Diffuser
- Exhaust
- Sill Plates
- Seats / Door Cards / Centre Console
- Steering Wheel
- Wheels
- Engine & Airbox

But need to know what wiring looms are different, i.e ones leading the the steering wheel, and maybe tailgate? Ideally need to know every single difference right down to nuts and bolts.

I presume theres no major differences, and everything would be transferable from a CSL to an M3.

Thanks, Craig!

[karbonkid]

Let us know why your asking and it may make it easier to answer.

[Craig]

All will be revealed, I just need to check I can give details without implication myself or anyone else. I own a CSL and would like to know what parts vary from a standard M3.

You have wrapped it:whistle:

[Craig]

Its a bit more complex than that, it's in the hands of solicitors fighting out the case. Once I've spoke to them tomorrow regarding posting pictures and information' i'll post the details if it's not going to cause any issues.

For the moment I need to work out if a payout is not recieved what I do as there are several parts left which are un-marked and could be either sold on or used in a re-shell. Even been considering building an E30 M3 w/ CSL engine and SMG.

UPDATED WITH PART NUMBERS

[Craig]

Thanks so much, thats handy as theres a few things I might have just gone OEM M3 not realising the CSL was different such as sway bars and lower arms.

[phat///M3]

Just a thought, but if you use realoem.com you will be able to compare all the part numbers between the 2 cars.

[windy]

That may take a while.... I'd reckon there's a fair few parts that make up an M3 or CSL, so comparing the two lists... :bigcry:

Fair point, but I meant to compare the bits that he wants to buy as Im assuming he is not building a CSL from the ground up.

Hi NZ_M3 were you born in the BMW factory, great to have people with that knowledge on the site, some really good posts you have had in the past as well:thumbs:

Blimey! You really are a mine of information! Very useful indeed.

Dare i say you need to get out more, however... ;) :hahaha:

[Craig]

Thanks so much, I've still got many idea's running through my head about what to do with the car. I'm thinking breaking it for bits might be the best idea, cut my losses then try and find another CSL or maybe dedicate an e36 for track use.

Orrrrrr.... CSL engines E30 with SMG!! - Must stop putting idea's into my own head.

[_Nathan_]

Build an e46 race car :D

[Craig]

Hmm mebbie, really do want to stay e46 if I can its all down to cost and what not.

You were out at the 'Ring in early July weren't you Nathan?

[Bealo]

E30 with CSL engine and Airbox now i would like to see that :thumbs:

[7.77]

E30 with CSL engine and Airbox now i would like to see that :thumbs:

seems really difficult, cause you have to keep all sensors/wiring loom from the E46.....or choose a new management system for the engine, but i know there is no after market management system for the smg gearbox, so :smt009........a challenge anyone ??

[windy]

You'd get a fair bit if you broke it, though obviously it depends on how much you get it for in the first place!

Front seats seem to be 2k, all door cards about 1k, wheel 200-400, centre console about 500... list goes on!

What state is it in at the moment then?

[_Nathan_]

Not me at the ring - probably the other nathan with the green one?

[TANKSLAPPER]

Criag what sort of damage have you got ?

I've got some bits front seats, rear seats, suspensions both bilstein and OEM, wheels.

If I can be any help, let me know.

[Craig]

Ohh it aint pretty, its gonna need a new shell if it was to be rebuilt. I'll get some pictures up of the damage later when I'm home from work.

[Craig]

Well, here it is....

There is a set of photo's showing how the damage occured, but I'm going to hold off posting those for the moment but will eventually hopefully be able to show everyone.

[_Nathan_]

Blimey. Hope one was hurt?

If you decide to rebuild as a road car then I've got a full set of airbags sat awaiting ebaying...

[Craig]

It's amasing the other party (which caused the accident) only had a little tear in his jeans, and myself and my passenger were practically un-hurt bar a few minor little scrapes mainly caused by the airbags.

It's certainly made me realise how lucky I was, as I would have been at the same time and place in my Exige, or Noble should I have got one. And I don't think that outcome would have been as good.

[csl_mba]

Glad you are ok mate, that looks nasty.

Im assuming you were not the one towing the caravan? :)

[Craig]

Haha, no photo's were taken of car just after the incident and the car had been recovered to a suitable location where it could be left for a day or two before been brought home.

[_Nathan_]

Presumably the insurance will just write that off and get you in to another one?

[Craig]

Easier said than done due to location.

[csl_mba]

Easier said than done due to location.

Are we talking about a certain toll road in Germany?

[TANKSLAPPER]

I hope things get sorted quickly for you.

No one likes to see a CSL write off

[_Nathan_]

I'm sure some do as in their heads it makes their cars more valuable ;)

[AlexGTT]

Very sorry to see this but more importantly glad you are OK. Hate to see nice cars damaged. :( Seems worse when someone else causes the damage. Hope you get sorted and back in a suitable replacement soon.

[glendog74]

Are we talking about a certain toll road in Germany?

:whistle:

Hope you get everything sorted soon...

[Jaw_F430]

As others have said glad your ok, just hope you can get sorted out with money or another car etc

[shimmy]

craig

any idea yet about ow bad the body and chassis is?

i reckon best bet is either to brake it and sell the bits or sell the nice CSL interior and then seel the engine and shell for a race car (or make the race car and sell it for CSL cup or other series)

[Justin]

Fook me Craig, I feel for ya:bigcry: Glad your ok though and that's the main thing. Ring's a scary place for sure, especially with the speeds we get up to in a CSL, and it doesn't help when it's full of numpties who haven't a clue how to drive it. Hope you can salvage something out of it.

[Bealo]

I hope things get sorted for you mate :thumbs:

[NZ_M3]

So sorry to see Craig - hate to see a pride a joy in that state.

I am of the opinion that the car is very repairable though - there's no cracked windscreens and the majority of damage seems to be concentrated on suspension arms and few minor chassis components (and the extensive cosmetic damage).

Good luck with your law suit and wish the best outcome for you.

[Craig]

Yes, it was a certain foreign road where I'm covered TPO only. As said, once everything is done and dusted I'll post a full write up and pictures it was an un-avoidable wrong place and wrong time incidents.

The car doesn't look too bad but the strut tower has come away from the body too (photos to follow) and the windscreen is broken. However all round the engine bay is perfect, thank god... even though it snapped the strutbrace off the mounts the airbox and engine are all fine.

I guess it's just one of these set backs in life, I'd like to say the money has come easy but it hasnt I have worked for it and will continue to work hard to fund any future purchases and of course my petrol head obsession lol.

[Bealo]

Good on you Craig, that's the attitude :thumbs:Being a petrol head certainly is an obsession...

[pinkpanther008]

Thankfully everybody involved is ok Craig, cars are replaceable.

Chin-up mate.

[azrael]

Absolutely gutted for you, worst nightmare :( not even duck tape could have got you home.

If you choose to rebuild it I'm sure there are all the parts you need hanging around here. If you forget resale and just get it up and running for track then you can do it cheaper in the short term. Or even sell some of the interior to fund the major repairs.

[glendog74]

Agreed - that's what i would do to mine if similar happened.

Track slag to the max! :thumbs:

[Craig]

I'd like to re-build it as a stripped and caged track car, but fear the damage to the shell is to excessive... I'm pretty good when it comes to working on car's but have never actually attempted to repair a car with this much damage.

Here's some further pictures showing you what I mean about shell damage. If anyone know's anyone who would be able to give me an answer on if this is 100% un-repairable then it'd be much appreciated.

I've got a full set of CSL suspension if you decide to rebuild and don't go aftermarket. Would do it cheap to help the cause. Might have brand new front bumper mounts also, you can have them if I can find them. Anyone else got anything? maybe we can club together to help return a lost CSL to the road!

Can't advise on the shell, but there must be people out there who can sort it and reinforce.

As an aside, Anyone seen a US series called Rides? They do some amazing stuff in the body shops on there

[Thorney]

Got any pics of the lower beams in the engine bay?

Its certainly a load of hours on a decent jig (I'd guess about 30) and a lot of parts to weld in but for a race car its doens't look dead just yet.

[Craig]

I'll see about getting it up in the air and getting some shots of the lower beams and underside of the car, from what I've seen all those look straight and un-damaged its just the strut top.

Take it I'd need to pull the engine out to have the repair work done? Then I've also got to factor in damaged doors and rear arches.

I've a rear bumper (without the diffuser) I'd donate FOC. Has a small crack along the bottom corner but apart from that it's mint, would be fine for track work.

[1cosmicboy]

hi craig ,feel for u mate ,i work in a body repair centre and from looking at the pics i think that would repair quite easy .my place has certainly repaired worse .all body shops are quietish at the moment from what i hear and would welcome the work ,if you got it all stripped out and delivered to a good repair centre they would welcome you with open arms ,if ur struggling for money just tell them to keep it for times when they are real quiet and fix a price before hand .wish u were a bit closer to me ,we are one of the only kite mark approved repair centres in the country and our jig bloke is shit hot .
let me know if i can help ok
michael ,think ill keep mine in the garage a bit longer now !

[azrael]

Also Simpson Motorsport do refurb bumpers so worth speaking to them.

I guess though it all lies on the chasis opinion...

[derek]

hope things work out for you Craig, it could happen to anyone

[Craig]

Thanks guys!

Michael - I can get the car to anywhere in the country I'm in the North East anyway, if you wanted to show the pictures to you're body guys and ask them what other photo's they'd want and what state of strip down they'd want the car then maybe we can get this car back on the road?

Of course payment can be made in any way, shape or form. I'd be in no rush either, what about the damaged arches on the rear quarters they going to be easy enough to repair?

[NZ_M3]

that's most definitely repairable from the photos I can see - I suspect the driver side front rail will be tweaked a bit from the damage to the strut and the lower sill/floor (back of wheel arch). Definitely a good couple of hours on the jig - but can surely be made as good as new.

The engine will definitely have to come out, so too the partial interior to repair that wheel arch floor.

The strut top is an individual piece where it broke off, so it's a matter a aligning the chassis and rewelding a top on there - a good shop will be capable of doing it without you even been able to tell that it's ever been touched (well in NZ they can at least).

I've seen lot worse bought back to life (including a 5 series that got T-boned) where the cost of repair was almost the same cost as buying a new car and a 7 series that needed a whole front end cut - needless to say when I went to see the cars I couldn't tell that it ever had a front cut put in and that was with the engine out and the car up on a hoist.

Good luck Craig!! Hope to see it back on the road soon in whatever form you've got in mind for her :thumbs:

[Craig]

Guess i need to do some sums and work out if its going to be economical to repair, aswell as all the jig work its going to need repair work to pretty much both arches, then the wings, bonnet, bumpers and doors need replacing and / or repairing. Its also going to need wheels, tyres, headlight, suspension, lower arms, brake line, new splitters and rear valance plus a whole host of other bits. I'm extreamely particular too, if I'm going to rebuild it i'll also be improving on it and making sure every bolt is copper greased and all parts OEM or of a very high quality.... Maybe I need to get some body shop quotes first, then get some part prices and go from there. Ideally I'd like to get my CSL back up and running too, but if its going to cost £20k I might think otherwise. I could be tempted to strip out the interior and fit a cage and harness ready seats so selling the interior would recooperate some costs, I'd be quiet happy making it into a dedicated track car, but I wouldnt skimp on the body repair work.

[Craig]

Im located in Guisborough, which is 7 miles from MIddlesborough so you're talking about 60 miles. I don't mind part finding either as I have a few trade accounts with places too.

Things might just be looking up a lil lol.

Guess i need to do some sums and work out if its going to be economical to repair, aswell as all the jig work its going to need repair work to pretty much both arches, then the wings, bonnet, bumpers and doors need replacing and / or repairing. Its also going to need wheels, tyres, headlight, suspension, lower arms, brake line, new splitters and rear valance plus a whole host of other bits. I'm extreamely particular too, if I'm going to rebuild it i'll also be improving on it and making sure every bolt is copper greased and all parts OEM or of a very high quality.... Maybe I need to get some body shop quotes first, then get some part prices and go from there. Ideally I'd like to get my CSL back up and running too, but if its going to cost £20k I might think otherwise. I could be tempted to strip out the interior and fit a cage and harness ready seats so selling the interior would recooperate some costs, I'd be quiet happy making it into a dedicated track car, but I wouldnt skimp on the body repair work.


You should be able to get most of the cosmetic stuff (front wheel arches, bonnet, doors, headlights, etc. of ebay (.co.uk and also .de) as most of those parts are shared with a normal M3, and the doors I think are even shared with any e46 coupe.

[Craig]

Yeh, do all M3's have the composite crash structures or just the CSL?

[Bealo]

Thing's could be looking a bit better for you Craig :thumbs:

Fingers crossed...

[Craig]

Could be, need to try and work out every part im going to need right down to the last bolt. Then work out the costs of those parts, factor in the labour and paint costs...

I'm very mechanically competent so the stripping and rebuilding can be done by myself, but I need to make sure the chassis is straight then work out whats bent on the rear of the car as the passengers wheel camber is definatly out of line too, this side made contact with a barrier but not a hard hit.

[_Nathan_]

I've got some CSL rear camber arms (different to M3 ones) you can have cheap :D

[windy]

Have your tried some of the specialist M breakers? If you're turning it into a track slag, you could put the lot in an M3 shell. If you found one that just needed a roof skin you'd be laughing!

Though I don't know if you can buy shells from breakers these days, what with all the legal nonsense?

[Craig]

Been new to the BMW game, although I know the mechanicals of the car I have no idea when it comes to specialists? Care to enlighten me with a few names and contact details?

Ideally I need to find an interior damaged, or blown up M3 lol.

[_Nathan_]

FAB are the BMW breakers that readily spring to mind.

I am very happy :)
I made a new discovery for something that is different in the CSL and no one knows (or I can be wrong and someone knew about it).

How did this came in my mind... the background.
I remember years ago in my E46 compact and another friend's compact, I was changing the spark plugs and when I removed the microfilter housing, I noticed that is was extremely heavy.
I couldn't believe this thing was so heavy and BMW made such a stupid design.
Some time ago, I was changing the air filter of the CSL and removed again the microfilter housing. This time... didn't felt so heavy as in the compact but I thought... maybe it's because I am much stronger now.
The last weekend I was thinking again about this housing, that I could make a carbon fiber one, to reduce the weight. At the same time, I was remembering that the one in my CSL felt so much lighter than the compact.
So today I decided to check !

Here you go my friends.

The CSL ones (fitted only in the CSL and no other E46) ->
Microfilter housing, bottom part 64 31 7 895 937 (http://bmwfans.info/parts/catalog/64317895937/) 1.050 kg
Microfilter housing 64 31 7 895 939 (http://bmwfans.info/parts/catalog/64317895939/) 1.630 kg


The ones used in every other E46 (including M3) ->
Microfilter housing, bottom part 64 31 8 362 894 (http://bmwfans.info/parts/catalog/64318362894/) 1.690 kg
Microfilter housing 64 31 8 370 066 (http://bmwfans.info/parts/catalog/64318370066/) 2.625 kg

Yes, the BMW engineers thought about it and stripped out 1.7 kilos from this microfilter housing.

NZ_M3, I think you can update the list of confirmed part differences !!!
:thumbs:

PS : I will continue my quest to discover every bolt that is different !!!

Awesome find Alex!! List updated!!

##Now waits for an influx of Yanks placing orders for the super lightweight CSL microfilter housing ### :hahaha::hahaha::hahaha:

I read a few threads were people bought the microfilter housing.

Updated list is on the way :wink:

So, here is the ultimate list with all the M3 CSL specific part numbers.
I wrote a program to scan ETK for all CSL specific parts of an LHD CSL and here are the results.

I think you will find that some of the items above are actually exactly the same as the standard M3 item.

Some times BMW sell particular items as a complete build up unit rather than individual items and list them differently for different cars - but it is actually the same as the standard M3 item.

The only items in the above that is actually different to the standard M3 are:

Interesting about the interior carpet - it seems it is LHD cars only - which leads me to suspect that the lighter carpet only came in the LHD cars and not the RHD cars - the reason - the RHD cars have the same carpet as the standard M3.

But awesome program!! I did it all manually originally when I compiled the list.

[alexk]

Hi Tom,

Yes LHD cars are also properly balanced and have a few BHP more than the RHD ones.

Is the radiator the same ?
Why does it have another part number ?

The LHD CSLs are more special than the RHD ones :blalalala:

ts...
I see a small complex here ;) :blalalala:

[_Nathan_]

Why do they have more power? Do they run a different manifold as that is the only difference made possible by having the steering wheel on the correct side.

Yes, the manifold of cylinders 4-6 is different between LHD/RHD.
I don't know what is the number but in the older days the RHD were usually 5bhp down because of the different exhaust manifold.

[_Nathan_]

5 bhp I can believe from the manifold, RHD manifolds are far more restrictive than the LHD ones, look at the LHD Supersprint and Epic manifolds compred to the RHD supersprint one, far better. Looking forward to getting a better LHD manifold on mine :thumbs:

Excellent! Amended!!

So did you guys find out anything more?? Like the interior coating codes ect?? :-D

Tom, are you adding these too ?

BTW, no info about color codes.
There is a lack of knowledge at BMW M.
I asked for the chassis stiffness, they didn't know the number.

Having said that. I somehow doubt what they said.
I personally think we need to count the welding points, the ones visible and compare them to a normal M3.

I started documenting the welding points.

You have too much time on your hands dude!

[cossack]

Wondering if anyone's compared which sound deadening was removed to be exact from the CSL compared to the regular M3 model. Can anyone run a reverse part number look up, on what sound deadening is missing from the CSL. I'm looking at shedding some extra weight off the car.

Inside or under the car??

Basically if you pulled the full interior out there's not a single piece of sound deadening stuck or glued to the chassis.

Apologies to Craig for dragging up your old part out thread ... see his photos when he stripped his car:

It looks like there is still some sound deadening when comparing the realoem parts list between the standard M3, and the CSL. That's why I ask, is it seems like there is some still present in the car. I may just decide to pull all of it out though.

Realoem isn't always correct. Over the years I've noticed a few discrepancies myself.

The only one that is still there is the one in the driver side foot well (RHD car)

Craig, apologies for stealing your photos - if you want them removed let me know and I'll remove them.

Thank you, I'm gonna be tackling this here shortly. I'm a bit worried how much road noise it really reduces, but once I get the airbox I'm sure I won't care about road noise.
