My dad is test-driving the car for a week now. He says that it has strong pull above around 1.8k RPM, but that it has nearly no power at all until it reaches there. He also mentioned that it won't kick down under throttle unless the kickdown switch is hit.

AC is working, and nearly everything else has been taken care of so far (other than cosmetics and suspension bits).

Does anyone have any idea why the car would be dead that low in the RPM range but pull strong above that? I know the peak power comes in pretty late, but still, it should have SOME pull that low, right?

If your dad drives a V8, I think your car is normal. :P

I've mentioned this before, but even my car feels similar. Not NO pull, just not nearly as much as slightly later in the rev range.

As for the kickdown switch issue, is the car in E or S? In E, that's normal behavior!

chlippo

check your gas pedal cable. it might need tightning

Saijin_Naib

Haha, yeah, he drives the 500e and currently is driving a volvo s40 1.8T, so maybe his perspective is skewed :P

You may have answered, but typically, what kind of 0-60mph/0-100kph numbers are you seeing in your car? I'm trying to get my dad to test that now so I can see if its improved or not at all empirically.

E or S? My shifter is simple: P - R - N - D - 4 - 3 - 2
I'm thinking that as well. I messed with it a while ago when I put in a new Throttle Position Switch and a new Switchover switch (the thing with the little caster wheels on it behind the throttle arm).

Perhaps after having all these items fixed the adjustments I made prior are putting things out of spec?

Shoomakan

I'll take a video of a 0-100 sprint in the car, but I have no accurate way to time it. I'll use a video program and measure from start to finish, I guess..

That little thing on the lower left of the shifter... You telling me you don't have that?

Saijin_Naib

No sir, nothing on my shift gate :\

Sweet! I don't need precise down to the millisecond, just a general ball-park video will give me an idea of whats realistic to expect from these cars 20+ years after leaving the assembly line.

chlippo

i think you should get something like 9 sec

Saijin_Naib

Is that from your 3.4L or the 3.0L? Aren't both fairly recently rebuilt?

Thanks by the way

chlippo

The 3.0 M103 when it was running 110% and strong was getting 9 sec (but had a shorter diff) so i think your M104 with the diff you have should make a similar acceleration time.
Didnt time the 3.4 amg yet as its not yet ready, waiting to my next vacation to go rebuild the fuel distributor with the gasket i showed you, and install the eha, try to pull some timing and we will see

Saijin_Naib

Ah okay, good to get something in the ballpark.

The mech installed the new fuel distributor gasket you showed me I also have a new EHA in there as well. He said injectors were fine, but somehow I'm doubtful.

AMGDave

The E/S switch on the shifter was only used on Euro models, or rather, was never installed on any USA-spec cars. It's an Economy/Sport switch which acts as normal in E mode, but in S mode it tightens the Bowden cable a little to provide a higher part-throttle upshift RPM. It has no effect on WOT upshifts. You can retrofit the entire setup but some of the parts are not orderable in USA (has to come from an overseas vendor), and the Bowden cable is different (and expensive).

If there is really no power off-idle, it sounds to me like low fuel delivery off idle; generally cured by adjusting the EHA. But I wouldn't expect to need that with a new EHA. However, I'm not that familiar with CIS injection - sorry. You'll need some 0-60 stopwatch data to figure out if you have a problem or not.

Shoomakan

Sai, I'll take a video as soon as I can. Keep in mind I weigh 300 pounds, so... :P

Saijin_Naib

Ah, sounds fun but not exactly worthwhile then :\ I think he adjusted the fuel mixture on the distributor already, so maybe it needs re-tweaking. Or perhaps the car is just a dog, who knows. I'm trying to convince my dad to get a timed run in so I know what I'm working with :P

Haha, thats alright. I weigh about 245 so I figure it'll about even out since Euro cars are lighter :P

royvotava

does anyone know if the 24 valve head will bolt on in place of the 12 valve? or is the bolt pattern different? im sure the timing chain for the 24 valve is slightly longer.

Shoomakan

No, for several reasons:

1. Different drill holes.

2. M103 tune is totally off for running an M104 head.

3. Threadjacker. :P

AMGDave

4. Different pistons.

royvotava

Thanks for the input. oh and i wasn't trying to thread jack i just don't see how to start a new thread.

Saijin_Naib

How wide is the 300ce trunk?

http://cgi.ebay.com/ebaymotors/94-ME...item5ae233ceaa

I kinda want this, but I'm concerned it'll be too wide to mount properly on the 300ce trunklid.

chlippo

i prefer ducktails. why this one?

Saijin_Naib

Its 75$ shipped :P

Also, it doesn't necessitate me losing my badging like the ducktail, and nowhere on it does it say AMG like the ducktails do.

It appears to be similar to the AMG design used with the early GEN I kits which was pre-ducktail.
Seller indicates that it is for a W124 but also keep in mind that the coupe trunk has a slightly different contour then the sedan.
The width might be correct but it might need trimming to mount flat to the coupe trunk lid.

Ed A.

Saijin_Naib

Thanks Ed! I knew that the contour was different, I just wasn't sure if the width of the trunks was different as well between Coupe/Cabrio and Sedan.

My bodyshop guy should be able to handle pretty much anything to get it mounted properly, he did manage to make my WRX STI Vortex Generator fit pretty damned perfectly without much issue

I figure that while he has the car, it might not be the worst thing in the world to get this cosmetic mod done. Silly yes, but I think it'll complement the slight drop and new rotors nicely.

Saijin_Naib

Here are some supposedly 3000k Amber H1 bulbs I purchased for use in my c280 Sport.

Let me know if you guys think they come close to being yellow. For color reference, they're installed in the same housing as Sylvania Silverstars.

AMGDave

Here's another guy who dropped a C36 motor into a W124...

Saijin_Naib

Nice, thanks Dave.

Maybe if I ever get Bucky back I'll work on that :P

I think my housemate may be getting a C32 though, so at least someone in the driveway will have a supercharger and an engine displacement above 1.8L (disregarding the c280 Sport)
