Todd, try Random Technologies. They make high quality high-flow cats. I'd say, the best thing to do is get a measurement for the OEM cat and give them the specs to see if they have a universal that can fit or have one made to fit the m111 exhaust.

I saw in the other thread that the headers are separated from the cat, so it shouldn't be too hard to get the measurements.

As for the dilemma you're going through, I wish I had some insight. From what you're saying (marbles rolling around under the car), I would also check to see if the muffler packing is toast. Only thing is, if that happened, it shouldn't send you into limp mode.

I didn't get a chance to read through the other thread you posted in, but I think you posted the codes that you got. I wouldn't be able to interpret them, but have you taken it to Auto Zone to get the codes read? I'm sure that'll help some people give you some better input.

Actually, I'm not going into limp mode, still have all the gears etc.
I'm getting misfires on different cylinders, but only when I put my foot into it. I managed to drive 20 miles from the nearest Autozone (borrowed OBD scan tool) without throwing a code, but had to go really easy on the gas and keep the revs down.
When the computer senses a misfire, it turns off the fuel to that cylinder to avoid dumping unburned hydrocarbons in the atmosphere, for smog.

Stop, turn off the engine and restart, and all cylinders are back.
This happens when the coil packs are starting to die too, but I already
checked that.

I'm going to Midas, since the other shop in town, said they couldn't find a
universal. My choices are a little limited locally, and I don't want to be driving too far. I noticed the engine getting a little hot last night on the way home, cooled as soon as I got off the freeway.
Normally sits just above 80 centigrade.

C230 Sport Coup

Well here it is quite some later, I'm at 124K miles.
The problem I mention here turned out to be a clogged cat, possibly brought on by misfires from me not tightening the coilpacks and plugs enough.

In any case, I'm still looking at;

How many miles can I get from my SC before it blows?
Anyone with high mileage 2002 coupes especially, please chime in.

I'm definately going to pull the alternator, and have it gone through,
something I can get done locally, but having the SC rebuilt,
closest place I've found is in Oregon, and sounds like they'd do a nice job for
$300. But I'd be without a car for a week!

Am I just being paranoid? Seems to be working fine!
If aint broke don't fix it right?
But then again, it might be one of those things that would die on a long trip
unexpectedly.
And that would suck, as I'd be at the mercy of some local shop, who'd want $2000 instead of $300-400.

OR I could do one of those snout rebuilds, but whats the common area of failure in the SC? Just the snout?
There's bearings in the back too, that no one mentions that often.

Yup thats the place.
Hard to beleive there isn't some place here in the bay area.

This goes for most Eaton style blowers....

Between 70,000 and 120,000 miles the factory coupler will likely fail. The holes in this coupler become egg shaped and this can cause a rattling and banging noise you hear in your supercharger.

- MADE IN THE USA coupler
- Bottle(s) of supercharger genuine GM lubricant with flip top easy to pour spout. We include 8oz even though most superchargers only need 6oz. It is better to have a little extra than not enough.
- Tube of the special aluminum sealer used on the blower housing.
- Typical installation instructions.

- And for an earlier post (?turbo?)...a picture...

C230 Sport Coup

What mean "we"?
You have a kit?
Well, if thats the case PM me, or post in classified, lest ye get in trouble.
Yes, I've seen those green pucks online other places.
I'd want to do bearing while I'm at it.

BF_JC230

Sorry that is a listing from an online auction...

I have gone down and picked stuff up from the local GM dealer on a few super charger projects my dad and I have worked on.

The CNCed couplers are very nice, the lat two projects have been very happy with them...

Most domestic companies list a maintenance schedule and a work job on super chargers...M-B and a few others say it is "life time" ... Nothing is life time and things need R&R - we know that...that is why we are on this board...

Good luck!
Jake

(PS - do you know how to measure a bearing to figure out what you need?)

Kristen

WTF!

There's a turbo'd version of this engine?

SeaCoupe

I know of one M111 version Turbo. The car was a monster, but what I recall, not very well sorted.


Ohhhh, and still on the Kleeman all alloy single piece unit and I'm at 161k miles. No issues.

C230 Sport Coup

Somewhere I read you made mention of some issue at around 90K miles, possibly related to the SC? No?

C230 Sport Coup

Actually, no. Would a GM dealer sell bearings for an M45 SC?
(I don't think they ever used that one, did they? )
Or could I just go to a local machine shop, and ask them to press new bearings? Would they have them?

If I could do this on my own, or with the assistance of a local machine shop,
that would be better. Turn around in a day or 2.

C230 Sport Coup

I saw a guy with a E230 at the MBworld meet in Pasadena last year.
That was a Euro version, not sold in the states.
M111 non SC. Somehow, he got a guy to turbo it.

But he started with an early M111 not the later SC'd one.

SeaCoupe

C230,

The dealer initially said the issue was the S/C, so I took it off to have it rebuilt and ported. The Steig people said, there was nothing wrong, but rebuilt it and ported it anyway.

I think the Chevy Cobalt SS uses the Eaton 45 S/C.

From what I understand of tolerances in the S/C, I don't think I would attempt the rebuild myself. When you look at how tight the veins are together, you may rethink this. Then again, you are Fiat guy, so I know you are crazy.

I had a nice conversation with a guy at Magnason the Eaton authorized place.
They actually replace the rotors and everything.

But I learned, that replacing the oil can definately help.
I asked why people only typically rebuild the snout (well in a round about way)
He said, the problems come when the coupler inside wears out, and some of the metal parts start to grind a little (not completely clear on this), but that releases some metal particles into the oil, which then gets into the gears, and
the oil also lubricates the front bearings, so it all comes crashing down.

He also stated, he knew of a guy with an SLK who got 220K miles out of
his SC. But said he babied it.
As those are on a clutch and not always spinning like ours, that seems more likely.
He also stated the expected lifespan is 100k miles give or take.

I read Heir Kranz, you're still on the original SC?
Maybe I'm just being overly paranoid!

Last thing I asked was about the rear bearings.
He said they're pretty stout, and not often prone to be the cause of failure.

C230 Sport Coup

Well, I got tired of thinking about it.
Sooner or later, the supercharger is gonna blow.
If I wait till it does I'll get f'd so hard by the dealer, I'll be bleeding for a week.

I spoke with the guy at Eaton, and I'm overdue for a failure.
Expected life is 100K. 124k+ is where I'm at.
But they don't have one on the shelf, would have to send mine!
I suppose I could just do a snout rebuild, but thats still something that needs to be sent out, since further research proved I didn't have the right tools to it myself, and a complete teardown and rebuild, is anywhere from $300-800 ($800 from Eaton, they actually replace the rotors!)
New is about 1000 at the least these days, they've gone up a lot since I 1st priced them at Duval at 650 !

In talking with Duval, they said their wholesale cost is at least 700 these days, so I just got tired of thinking about it, rebuilt, what to rebuild, who to have do it, BLAH!
I want my car to go another 50-100K miles, and not leave me stranded so....

There is a guy on ebay that sells rebuilt and claims to have the
correct unit http://cgi.ebay.com/ebaymotors/ws/eB...category=33741

but he states it the same for all years SLK and C class , both W202 and W203...and many of those have the clutched pulley, so I know they are not exactly the same, + he's charging 250 for the core, and it has be returned in 7 freakin' days!
Well screw that...ha, literally. (roots style screwing ha)
He does offer a 2 year warranty, but uh...in an ebay store?
Will the guy be around in 2 years?
If he send me the wrong unit what then?

So, it's done
I just bought this.
http://cgi.ebay.com/ebaymotors/ws/eB...AQ:MOTORS:1123

If they get 250 for a core, so can I. Nothing wrong with my sc, just lots of miles. So, that being said, if I sell mine as is, (and I saw one got 375 used AS IS) the buyer pays the shipping (not me), and I get a new SC for about $375 or even less(! if I get more than 250 for the used one).
OR send the old one out to Steigmeister for porting and rebuild.

I wondered a little about the red seal around the snout, but it does look new, and he swears it is.
No warranty is mentioned, but it's absolutely the right pn, and his feedback rating is close to perfect.

tommy

Did you fix the cat yet? I've got a Magnaflow on my car; I didn't buy it myself, unfortunately.

Let me know if you want me to check for a model# or take pics or measurements, and I'll do it. It was less than $200, and have had no problems with it. Decided on that after a $1350 quote for a stock replacement when mine failed.

SeaCoupe

I really don't think that you need to have the vanes/rotors replaced. Mine looked great. Only reason would be, if you remove it, and see that the teflon coating is cracking/flaking off. I paid about $700 during a seasonal special to have mine ported and rebuilt.

tommy

Emr - did you do any before/after dynos?

C230 Sport Coup

You're addressing me? Yes, I replaced the cat, passed smog, (check my "hide-a-header" thread).
What was it that you did for 200?
You mean the Cat? Yeh, got mine installed for 300.
They had to do some serious pipe bending.
Tommy, how many miles do you have? Any issues with your SC yet?

E, don't have to worry about replacing the vanes, i got a BRAND new one!!!!

SeaCoupe

No, but I do get better mpg, and you notice a longer and fatter midrange.

A side note, it also makes the S/C sound throatier, and gives it far more sound. Silly, but fun when the other MB ****** are around.

E

C230 Sport Coup

I know I keep asking this, but that other guy who sold his
ported SC, had problems, but you aren't experiencing any problems?
None? No oddball CEL codes? Top end cut out?
Once I get the new one in, I'll be very tempted to send the old one out...

tommy

I just passed 104,000 recently. No issues, but yes, you're getting me worried!

Yes, my cat was $200.

Like you, I'd really like to extend this car another 50-75 or so. I'm taking my crx out of storage tomorrow, so at least I'll be able to decrease the summer mileage by taking that every so often. The Benz is fun, but the Honda is funner.

Emr - that sounds like a decent improvement. Might have to think about that if I decide to get the sc rebuilt, and add the porting into the mix.

SeaCoupe

You are talking about RTKing. He had the same work done. Our cars will run lean with the pulley. Add the S/C, and you make the situation a bit worse. However, the car will correct as best it can. I think the ported S/C and a bored TB with bigger injectors and tuning could yield mucho gain. Say all in 20 to the wheels.

E

C230 Sport Coup

Well, as you have a 2nd vehicle, it's not such a big deal. No worries.
I was considering getting a 2nd car, but for various reasons I can't right now.
(parking for one)
So, I'm trying to do in advance rather than wait.

I have a leaking manifold gasket, so once I get the SC, I'll
do that, pull the Alt, have it rebuilt, and then, I shouldn't have much to worry about. (Knock on wood.....though it can't be just any wood....has to be from the Black forest in Germany to do any good)

Considering the price I'm getting it for, and then selling the old one while it's still functional, it'll be a good investment in reliability.
The guy at Eaton said he knew of one guy with an SLK that got over 200K miles, but he said the guy babied his car.

I don't drive hard a lot, but the times I have, and having a pulley, how many more miles can I reasonably expect, 10K? 20K?
If it happens on a long trip I'd be stuck having to pay a mechanic.
This way, I don't have to worry for another 100K miles at least.
Same with the alternator.
Seems most people around here get a failure about 130-150K miles.
