SL 300D superturbo
SL 300D superturbo
and creating a SL300D turbodiesel or a 300SLD..
so I have a myriad of questions, and I am fishing for some answers.. I have just begun this phase of the project
so while some research has been done, by no means is that complete. I thought I would boost my research
with posts to this and other forums and tap into the vast knowledge base that is out there..
anyway the project photo gallery/journal is located here for those interested :

so below is what I am facing so far..
what am I missing ?
what else have I not thought of ?
thoughts ?
suggestions ?
incorrect information ?
must have electrical systems:
(minimum needed to run)
* starter circuit
starter motor to bat + and solenoid connections to starter switch.. should be a no brainer here.
* glow plug relay
connections from relay to glow plugs (six pole plug )
connection to battery and ground
signal wire to glow lamp indicator on dash
what else is involved with this circuit to enable its operation ?
temp control for glow length operation?
several other wires.. have not traced them
research this more with wiring diagram....
engine monitoring systems:
* water temperature gauge connections
should be plug and play.. hopefully
* oil pressure gauge connections
also plug and play.. hopefully
EDS
Electronic Diesel System
so it appears that this segment of the EDS system is basically all of the ways to turn the AC compressor
ON or OFF:
OFF or back ON via the kickdown switch (S30/1)
OFF or back ON via the automatic transmission switchover valve (Y3) triggering the kickdown switch (S30/1)
OFF via an overspeed condition of the AC compressor (L4) speed sensor
OFF via a low pressure condition on the AC pressure switch (S31)
OFF or ON via temperature condition by switch (S25/11)
OFF or ON via AC switch (S27/1)
<!-- m --><a class="postlink" href="http://www.coastalboatsales.com/jfraley/gallery/SL300D/W124_elec_EDS_ACsystem">http://www.coastalboatsales.com/jfraley ... S_ACsystem</a><!-- m -->
The remainder is the fuel control portion of EDS (idle control)
<!-- m --><a class="postlink" href="http://www.coastalboatsales.com/jfraley/gallery/SL300D/W124elec1">http://www.coastalboatsales.com/jfraley ... /W124elec1</a><!-- m -->
inputs to this system are:
Voltage supply via OVP relay (K1)
engine speed via speed sensor (L3)
coolant temperature via sensor (B11/4)
IP control rod travel via sensor (L7)
air quantity via AFM (B2/1)
manifold (boost) pressure via OVP relay (K1) ?
barometric pressure via sensor (B18)
base circuit resistance via reference resistor (R18/2)
resistance trim via ELR knob (R18/1)
outputs are:
varying voltage to the ELR actuator (Y22)
voltage to vac transducer (Y31) and on to the ARF valve (Y31/1)
test connector diagnostic block
Based on what I see, its basically a big resistance loop with all of the input factors increasing
or decreasing the resistance ( plus the base resistance ) of voltage flow to the ELR actuator
which is on the backside of the injection pump. More voltage=more fuel, less voltage=less fuel.
Pretty simple... Base idle is set with ELR in central position (4) with mechanical stop. Base resistance
can be fine tuned with ELR knob.
* EGR (exhaust gas recirc)
I plan to disable this completely
* PCV ( crankcase vent)
I plan to disable this completely by dumping the vent into a air/oil separator
and vent the oil-free air out of the engine compartment via hose
* Air Flow Meter
I plan to remove/disable this completely
* ARV (air recirculation valve)
disable/remove this
* cruise control
related to EDS as far as sensors ? ( dont think so ) what other inputs are there ? tach ? transmission?
* OVP
appears to be just a feed relay to the EDS control unit, but it is connected to the vac switchover valve
that feeds boost signal to the ALDA, not sure what else is incorporated in this yet.. need more research
At this point I feel pretty comfortable with the EDS system, and I am tyring to decide if I want to keep it..
after removing all the emmisions and other non-essiential crap I am left with this :
<!-- m --><a class="postlink" href="http://www.coastalboatsales.com/jfraley/gallery/SL300D/W124elec1_modified">http://www.coastalboatsales.com/jfraley ... 1_modified</a><!-- m -->
do I bother keeping the entire system with a good portion of it removed ?
It will probably still function if I terminite the not-used wires with either reisistors
or maybe simply leave them unconnected.. a study of the control unit schematic may help
(if its even available )
so what do I really need ? can I just connect power thru the OVP to the ELR actuator
trimmed by the ELR knob and just call it a day without all the feedback loops ?
Or maybe just set the base idle up a bit mechanically so when the A/C is on its not too low ?
vacuum systems:
* wastgate/boost fuel control
from sixto:
The ALDA gets a boost signal from the manifold. A line goes to a VSV which is hooked up to a pressure sensor on the manifold beside the ALDA signal nipple. Pretty simple set-up - +12V to the VSV when the engine is running and a ground signal from the pressure sensor above 1.1 bar. No electrical connection to EDS or anything else. And of course a signal line from the VSV to the ALDA. There's a splitter at the ALDA for a boost signal to the transmission vacuum amplifier. Again, 617s and 603.971s manage without this boost signal to the transmission modulator.
* other vac connections on IP
fuel cut-off connected to ignition switch
I will have to install an electro-vac solenoid possibly tapping off the
ignition coil power wire to control IP fuel-cutoff
study of vac diagrams may help
possible solution for fuel-cutoff: <!-- m --><a class="postlink" href="http://www.grainger.com/Grainger/items/1TMT1">http://www.grainger.com/Grainger/items/1TMT1</a><!-- m -->

the vac system could maybe be simpler.. have to work on this further....
Transmission:
has electrical connection (four pole plug i think )
what does this do ? just the reverse light and possibly neutral safety switch
FYI I am using the 124 transmission ( not sure of the model )
update: this connector from the W107 car plugs right into the W124 trans..
probably just light and NSS, have to verify with wiring diagram.
control boxes / relays behind battery:
several units .. the EDS in one of them (detailed above)
I think the other one is related to the climate control..
OVP and the A/C relay
other items to boost performance once I get it running reliably
Send out injection pump to myna diesel in finland to be upgraded
or figure out what they do to get more fuel ( bigger injectors etc )
Upgrade turbo+up the boost, holset hx35 is supposed to plug and play with
stock exhaust manifold on the 603.
update: not planning to use the stock manifold, I think I will build a tubular header and use a Holset HX-35
Add an intercooler, I will have to do this, as the the turbo interconnect pipe will not fit with this arrangement
in the W107 car. Plan to locate right behind grille in front of AC condenser and radatior, which will involve replacing
electric fans to behind the cooling stack, with puller units ( instead of pushers ).
This will also involve the removal of the mechanical fan and clutch assy.
Climate control:
The plan is to use the compressor from the W124 and attach it to the W107 climate system. I think the electrical triggering
of the compressor will be all that I have to do.. with the exception of idle control via EDS and the whole compressor
relay mess.. I may come up with some hybrid of W107 and W124 parts.. more work on this needs to be done.

oel_brenner * PCV ( crankcase vent)If you are going to make your own exhaust system, consider venting it into the exhaust (after the muffler). That will provide some suction to draw the gasses out and make a vacuum, prevent any "smoke" coming from under your car (very embarrassing, I know first hand) and partially burn the remaining oil vapors when the engine is loaded (and CC gasses are highest). Ford Powerjoke owners (which is known to have really nasty blowby) do this often and have great results. The hardest part is avoiding low points in the CCV tube to prevent oil pooling.

All you need is a simple vacuum solenoid. These can be found on almost every car on the road and would cost about $20 to buy new. Your 300TD donor body should have several in the climate control and emissions systems that would meet your need perfectly.

yeah.. thats a good idea

I may come up with a super simple resistance circuit that does away with the control box and just uses a couple relays and a potentiometer to fine tune idle that I could mount on the dash
ForcedInduction You don't need vacuum for the wastegate or fuel controls. The only things you should need vacuum for is engine shutdown, transmission shift firmness and body consumers.
so i just plumb the ALDA directly to the intake manifold port and give it a "boost" signal ?
and the transmission only needs vac for mechanical shifting aid ? is not interconnected to anything else ?
I am going to work on a updated vac diagram.. based on this.

the W140 manifold looks good, but I dont know if it will give me enough clearance, as it appears the turbo "hangs" down and away from the engine, and due to space issues under the hood of the W107 I may be forced to build a tubular header that places the turbo up above the exhaust ports and close to the valve cover. and yes.. the TrapOx is pure evil. :evil:

IIRC from my volkswagen days this pump kept constant pressure to the CIS system at 60 to 90 PSI or so.. I imagine this pump is the same
I was about to remove the pump and filter and related stuff, I before I did I though maybe I would keep it and pump diesel/biodiesel up to the front of the car, step the pressure way down and feed the big fleet type primary filter I plan to run.
Also there is an additional (third) large fuel sized hardline that runs to the back of the car, it was the fuel vent box to the charcoal so I could dump and extra fuel back to the tank via this line and "polish" the fuel as I drive.
the the main line from the tank would go thru the stock fuel pump and thru the pressure regulator thru the big primary fuel filter and to the lift pump.
the engine fuel return would use the stock fuel return line
and this third hard line could be used as described above.
issues:
will the pump hold up to diesel/biodiesel (rubber parts/seals inside )
will it even pump diesel ? ( I would think so..it would not be working that hard as the pressure would not be allowed to build up.)
what do you guys think ? I wanted to ask the collective genius before I remove the stuff

oel_brenner what about this for a vac diagram..
Sounds about right but you are missing some lines to/from the vacuum valve on the injection pump for the transmission.

shifting is "firmer" or quicker ?
if it is completely disconnected what happens ?

got enough of the electrical done today to give it a test fire..
no cooling system or exhaust other then the down pipe
turbo not connected, and no vacuum anything yet...
but I could not resist firing it up..
hopefully I can connect up a few things tomorrow and go for a quick ride around the block
looks like I may have an issue with the starter, but anyway.. I made a video of the first run..
its uploading to youtube and the project page now
I will post URL's in a few min

when I sit my 200 lb ass on the radiator support, the front sits level with the back
still too high though, need lower springs, and the shocks are all worn out also, so I'll do em all at the same time
no vogtlands avail for the W107

have to search around.. or find some thicker units from maybe a W126

There should be lots of performance products and body kits for the R107. A lot more than for the W123 anyways.
cooling system / heater circuit complete
oil cooler bracketry fabricated
power steering system complete
glow plug system complete ( save the dash glow light indicator )
alternator / charging system complete
coolant temp gauge complete ( needs calibration checked.. W124 sensor W107 gauge )
vac system complete ( save IP shut-off solenoid )
neutral safety switch works..
transmission cooler complete
items remaing:
vac IP shut-off solenoid.. ( need to get to the junkyard and find something suitable)
remaining engine sensors.. oil pressure etc..
A/C pressure hoses and electrical connections
exhaust system
shocks, springs
and lots of other stuff
I am trying to get the car operational so I can drive it around for a week or so
and work out any kinks and issues before I start on the cosmetic stuff
fresh pics on the project page..

You're going to cram A/C in there? I'd be happy with taking the top off.
the low pressure hose just screws together.. no mods of any kind..
I will have to make a custom hose to connect the high pressure side.
connect the compressor clutch wire.. and its done.
everything else is stock W107.
AC is an absolute must in FL
top down does not cut it in the middle of the afternoon

car is driving around nicely, still need to set up the suspension properly
shocks springs etc..
next week I plan to start driving it around as the daily driver to work out the kinks
with everything, then its time to paint the outside, redo the interior and then on to HP mods.
found some euro lights, and got a black german canvas top in really fantastic shape for $200, and many other bits...
believe it or not, I think its already faster then with the 3.8L V8
granted it had over 200K on it and was burning oil
the OM603 is lighter then the V8 and although it makes less power, the car feels faster....

found some euro lights, and got a black german canvas top in really fantastic shape for $200, and many other bits...
believe it or not, I think its already faster then with the 3.8L V8
granted it had over 200K on it and was burning oil
the OM603 is lighter then the V8 and although it makes less power, the car feels faster....

I wouldn't mind having this creation. What exhaust did you wind up going with?
'78 300D, OM617.912: 4spd manual, TB03 at 10PSI, 26*BTDC, DV's turned, HVAC, emissions system removed, e-fan, short ram, 3" downpipe to straight exhaust, W126 Bendix brakes, MR2 Spyder seats. 2890lbs
I know what you mean about the 603 feeling faster. My friend has a 380SEL and I drove a 300SDL and I swear the SD feels faster!

still a hacked together collage of a Porsche 944 rear section and muffler, and some scrap pipe welded to the stock downpipe.
just enough so I can drive it and its not too loud.
its really temporary
on another note..
the springs are in..
(waiting on shocks.. monday for sure..)
but new ride height looks good with the late model SL wheels..

Ah, much better. Let us know difference in handling characteristics.

The only good thing is that soft top...that's pretty. Where did you get that?
driving the car almost daily.. still working out some issues, but I have to say
it drives much better then the V8. The front end feels lighter and handles better
with the 603 under the hood.
Still have all the bodywork and interior work, but mechanically its 85% there.
also.. have a look at the new license plate for it.

I'm very happy how its turning out. I just wish MB would catch the ball and make an SL420 CDI over here.
I plan to get some video this weekend on the road..
so I think the next project should be
a W129 with an OM606 turbo... now that would be a fantastic car...
once I get the turbo controller finished for the W124, and the W107 painted, and.. and... and

EDS
Electronic Diesel System[/b]
so it appears that this segment of the EDS system is basically all of the ways to turn the AC compressor
ON or OFF:
OFF or back ON via the kickdown switch (S30/1)
OFF or back ON via the automatic transmission switchover valve (Y3) triggering the kickdown switch (S30/1)
OFF via an overspeed condition of the AC compressor (L4) speed sensor
OFF via a low pressure condition on the AC pressure switch (S31)
OFF or ON via temperature condition by switch (S25/11)
OFF or ON via AC switch (S27/1)
<!-- m --><a class="postlink" href="http://www.coastalboatsales.com/jfraley/gallery/SL300D/W124_elec_EDS_ACsystem">http://www.coastalboatsales.com/jfraley ... S_ACsystem</a><!-- m -->
The remainder is the fuel control portion of EDS (idle control)
<!-- m --><a class="postlink" href="http://www.coastalboatsales.com/jfraley/gallery/SL300D/W124elec1">http://www.coastalboatsales.com/jfraley ... /W124elec1</a><!-- m -->
inputs to this system are:
Voltage supply via OVP relay (K1)
engine speed via speed sensor (L3)
coolant temperature via sensor (B11/4)
IP control rod travel via sensor (L7)
air quantity via AFM (B2/1)
manifold (boost) pressure via OVP relay (K1) ?
barometric pressure via sensor (B18)
base circuit resistance via reference resistor (R18/2)
resistance trim via ELR knob (R18/1)
outputs are:
varying voltage to the ELR actuator (Y22)
voltage to vac transducer (Y31) and on to the ARF valve (Y31/1)
test connector diagnostic block
Based on what I see, its basically a big resistance loop with all of the input factors increasing
or decreasing the resistance ( plus the base resistance ) of voltage flow to the ELR actuator
which is on the backside of the injection pump. More voltage=more fuel, less voltage=less fuel.
Pretty simple... Base idle is set with ELR in central position (4) with mechanical stop. Base resistance
can be fine tuned with ELR knob.
.....
Do you think the EDS has no function in determining the fuel dosage it is inyected in the engine?
From yr experience, the components of the EDS are just resistances to give a variable voltage as output. My idea is to relate this voltage with fuel consumption. Based on what you say, I am in the wrong way.
What would you do?
