    Yep you're right on the expense ... but the car will be staying in the family forever ... It is set in my estate and will be handed down continuously ... (hopefully barring any major catastrophe) ... There are several good body restoration guys out there so I am sure even going the restoration process without the frame off would work as well. It just has to be right. The biggest problem yet though is getting this darn rev's down and the light working properly!

    The car sits for approximately 6 months of the year and then is driven a limited amount during the other six months ... I am wondering if the fact that it sits in storage that long might have an effect on the rev's and the light etc?
  • I can understand that you have a sentimmental attachment to the car, but that would be the only basis on which to go for a frame off restoration. It is just not financially feasible to justify such an expense for a 107. If the car is in relatively good shape with no rust etc it would make sense to do whatever repairs and maintenance are needed to bring it up to par. Even a good paint job will run you around $5,000 and if the original paint is pretty good, there's not much point. Taking an "85 to a Mercedes dealer is pretty pointless as their technicians are comparatively ignorant about anything more than10-15 years old. I don't know of a good shop in Vancouver though there must be one and the local Mercedes club members must know at least one. There's an excellent guy in Nanaimo that I use and another in Qualicum that has been recommended to me twice. If you're stuck and can handle the ferry I'd be glad to pass on the contact information

    Sounds like a neat plan. Here's a thought, though: might the car be more meaningful if kept in carefully-maintained original condition? A 'frame-off' restoration will result in something close to brand new, with the marks/scratches/bumps/etc. (the history of the car) removed. I just know I enjoyed all the 'character' my dad's antique car acquired as I grew up, compared to a fully-restored prize-winner.

    Just a thought.

    When you say uncontrolled high revs what do you mean exactly? How high? I'm not sure on an 85, but if it has mechanical fuel injection it's a sure bet it has a mechanical cold start fast idle control that is probably controlled by the coolant temperature. It basically just allows air to pass around the intake air control valve independent of the throttle. Over time they get corroded and can cause idle problems, but I don't know if I would describe it the way you have. When I have had problems with it in the past the idle would hover from normal, about 600rpm to 1100 or 1200rpm. Also, the rubber hoses that connect the valve to the intake could be hard or deteriorated and allowing air to pass into the intake around the valve.
  • Sorry been away travelling .. but I think you might be spot on with this diagnosis. I will check into that for sure. That is exactly where the car goes to and from in RPM's
  • Another great point by the way. I enjy driving the car cause I can smell my Dad in it ... its a good smell by the way ... but just that feeling of knowing he was in it is something that can't be replaced and would be lost if I restored it in the manner I discussed earlier.
  • Wold you know anyone in the Mercedes club here in Vancouver ... preferrably West Vancouver. At least that way, I could start to meet some of the guys and see what they think about the few mechanical situations. They may even know someone locally who is trustworthy and knowledgeable.
  • Sorry, I don't know anyone in the Vancouver club and when I looked up the website of the Vancouver section of the MBCA there were no contact names or numbers. Whether this means that they are inactive is anyone's guess. I was given the name of a Mercedes specialist on the lower mainland with a good reputation though, and it might be well worth your while to at least contact and talk to them - unfortunately not in West Van but I hope North Van is not too inconvenient for you. The name is
    Scan Automotive, 1118 E3rd St. North Vancouver. Phone# 604-980-4542. Best of luck and if you ever cruise over to the island, let me know.
  • Hey thanks for this info. I was going to give Vaughn a call as well... he is a friend of mine at Vancouver Mercedes Benz. He might know of a club member or a club for that matter. I will drop by Scan Automotive and have a chat. Is there anyone there in particular I should ask for?

    I will definitely drop you a line the next time we go for a cruise over to the Island!
  • Until I enquired around and was given the recommendation I had never even heard of them so have no idea who you should ask for. Hopefully they'll be able to fix you up though
  • I have heard about a pulley arrangement specifically for 107 hardtop removal and replacement that is comparatively easy to set up in a normal garage. Does anyone have any information on this subject such as where one can be found and approximate cost? I haven't actually used my hardtop since I bought the car but probably would if it was not such a pain to take it off and put it back on. I understand that the hoist in question can be easily operated by one person. Any info would be appreciated.

    Boy, that was quick! Thanks for the info. While we're in touch, do you have any information regarding a compatible supercharger for a 280SL or is it just a bad idea?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,529
    Well it's not for me to tell you it's a *bad* idea....even though I often do tell people that "if you want a faster car, just go buy one" :)

    I did see a nicely done installation of a Ford 289/V8 into a 280SL and a supercharged GM V-6 in a 190SL, but neither of these projects were *cheap* by any stretch.

    I'd say that a custom-fitted turbocharger would be easier to configure and design, and less expensive. But I've never seen one.

    You're quite right regarding buying a faster car. In fact I originally went looking for an '85-'89 500SL but found an '85 280SL with the makings of a cream puff and went that route. I have never really regretted it and have no desire to change but there are times when a little extra kick would be nice. My experience of turbos is that without an intercooler they are not terribly effective and that could take up quite a bit of space. I thought I would investigate the possibilities of adapting a Kompressor from one of the newer C series but only if everything can be worked out without in any way wrecking what I now have. Thanks for your comments
  • texasestexases Posts: 5,531
    Instead of the Kompressor, an easier route would be to look at aftermarket supercharger vendors, they might be able to work something up that would be correctly sized, etc. That said, I'd just make sure it's in top tune, wax it, and enjoy it as-is.

    I don't know what you could do with the supercharger off a 4, the supercharged 6cyl models are somewhat rare and likely such a part is not easy to find. It might be easier to just find another entire powertrain if you want a more powerful engine.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,529
    If your engine has any flaws, a SC or turbo will find them right quick.

    I know they used to rally-race 280SLs in the old days, but I have no idea how they made them go faster. I'd imagine you could mill the head, find a better camshaft and run dual Webers along with better exhaust, but that's going to a lot of $ per horsepower.

    The nice thing about turbo power is that it is cheap for what you get in gain.

    Okay, so you have the 280SL with the 450SL body style---in that case, have at it---that car is not going to be worth lots of money, so not problem in "ruining" it for the purists.

    Yeah, it's a 107 - no racer, just a nice cruiser.

    If I wanted a better engine for one of those, I'd try to find a V8 out of a W210 E55 AMG (or even a C43), or for cheaper and easier, the M103 I6 out of a W124 or late W126 - the latter was actually offered on Euro cars, and would likely be an easy fit.
  • Thanks for the suggestions Fintail. Problem is I would like to keep the car as original as possible and a turbo or supercharger can be taken off pretty easily while an engine swap is a whole different deal. As you state, it's a great cruiser and I didn't really buy it as a dragster so maybe I'd just better settle for what it is
  • fintailfintail Posts: 33,560
    That's what I would do. Frankly, I think the engine mods or swaps would be a huge pain and a waste of time and money. It's not meant to be a speed demon anyway - it can keep up with traffic just fine, as long as the engine in the car has no serious needs - let it be.

    On the 280 dohc you can get offset woodruff keys for the cams to vary the cam timing. That's the reason the euro 280 cars have so much more power than the US spec cars. I don't know about an 85 but the earlier 80's 280 dohc US spec cars had around 140 bhp, as opposed to over 170 for euro spec cars.
    It's not a job for the faint at heart though, MB manuals show the procedure and specify measuring the valve to piston clearances as part of the procedure.
  • According to the owner's manual the "85 shows 185hp @5,800rpm. The car is far from sluggish, especially when compared to the US version of the 380SL but could sometimes use just a touch extra oomph. For what is involved in providing a little more get up and go at slower speeds, it is probably better to let well enough alone but thanks for the information anyway. She has plenty of passing power at cruising speeds.
  • I have a 1996 SL500 w/40K miles. It usually runs great. Recently, I started it and drove down the street. As I hit the accelerator, the car hesitated and then bucked/backfired in the engine area. It did it a few times. Then it stalled. I pushed it to the roadside and came back and it restarted. Took it home. The same thing happened a few days later. Then, I was able to start it and SLOWLY take it on the road. It backfired only when I gave the pedal a push. It almost stalled. But, if I let it get up to speed slowly, it would't buck or stall. I kicked it up to about 90 mph. and no problem. But, slowly moving and trying to quickly accelerate, I get that backfire and stall. Any good Benz men out there?-- Thanks

    Being a '96 it should have OBDII computer readout - you might be able to get it scanned for free at a car parts store, let us know what codes it shows.
  • fintailfintail Posts: 33,560
    Did any check engine/idiot lights come on when this happened?

    My old W126 behaved like that once, but the dashboard lit up at the same time. Some relay had failed, easy DIY fix - but it didn't have the same engine as your car.
  • Thanks for the reply fintail. No lights came on. Nothing indicating a problem
  • Thanks Texases. I'll call a parts store and see if they know what an OBDII is--I sure don't-lol and I'll see if there is any type of code that is involved with the situation
  • fintailfintail Posts: 33,560
    Could be a number of things - fuel delivery, vacuum system, timing, ECU...best to have it scanned then.
