Some actual progress.

Been gathering parts for over 2 years and decided "now or never". Throttle body and everything downstream is Ford Explorer, EDIS, MS2 for ECU under passenger seat, Volvo EPSP to replace the P/S pump. Will be removing the D-Jet intake for easier access tomorrow. Lots of detail work to do. No turning back now. Decided to wait on the Turbo till next year.
1975, 280SL.

Very cool.
I like the look and thinking outside the box a bit on this. I am really interested in how it will turn out with a turbo. Should be a neat setup when you are done.

Moving along. D-Jet wiring removed, MS installed and wiring run through the firewall. Custom overflow tank made and pressure tested, original removed to make way for Explorer fuse and relay panel. Benz put 4-5 circuits on each fuse,
original panel will be strictly body fuses (windows, lighting etc.) new will be engine related.

why using maf sensor not map?

I personally feel MAF is more accurate. My MS is wired for both MAP and MAF, when it's time for the Turbo, will switch to MAP. Simple change in Tuner Studio.
Using the MAP now for barometric correction.

As of today: realized how much easier making the mod's would be with the engine out so; 3 hours later. Old IAC now has cover, throttle body heater is bypassed, new fuse and relay panel made just waiting for my wife's kiln to be available then powder coat; new wiring, connectors and boots for the injectors,
made template and started the layout for the Turbo moving what needs to be moved. Made up the exhaust befor engine removal so it's ready to go. Next up:
finish Turbo manifold, find tranny leak, run all the Megasquirt wiring. Glad I started this blog, makes me realize things ARE getting done. Sometimes I wonder.

Re: Volvo steering pump
Does the electric pump provide operational advantages (variable pressure, variable volume, pump-on-demand operation, etc.), or is it mostly for location flexibility?

Looking pretty good. Just a couple of questions:

It's hard to see from the pictures but what did you do about the original distributor? You say you are using a Ford EDIS system but what are you using to drive the oil pump? That's been a sticking point with my M115 and M110 builds.

It looks as though you are using the Ford control module to run the spark. was there a preference to this instead of adding coil drivers to the MSII or simply a case of "it's already there so why not use it"?

Looking forward to seeing your mounting of the pick up module. This has been a thorn in my side on my M110 conversion. Been running it "fuel only" because I haven't come up with a decent set up for the pick up. I've got a trigger wheel made and I'm waiting for my machinist to do the final fitment. I'm going on the inside of the dampener (which I don't see in any of your pictures, did you eliminate it or is it simply not shown?) which will allow me to use the existing timing bracket.

Is that a temporary mounting of the fuel pump? Those pumps are meant to be "pushers" and I think you'll be better served mounting it at the rear near the fuel inlet. I suppose you could be using it in tandem with the existing fuel system but that appears to be extraneous.

Hard to tell from the pictures but what are you using for a fuel pressure regulator?

The direction of the coil facing, is this a case of "that's how it was" or a best fit option? I think you are going to have a plug wire mess on your hands the way it is, plus the exposure to any fluids, debris, etc. I'd re-work the mounting bracket to where the spark outlets on the coil face to the rear. This would simplify the wiring runs. You could use the existing wire routing/looms also for a cleaner look.

Doing a great job, looking forward to seeing more of your progress.

Plan was to replace the original Power Steering pump (a Vickers if you can believe it) and use the location for an M62 Kompressor from a C230 but decided to go with the Turbo instead. Besides, that pump is HUGE.

A) The oil pump mechanism drives the distributor, removing it doesn't affect the pump. You need to replace the hollow bolt with a solid, all it does is inject oil into the distributor gears. (see pic's)

It looks as though you are using the Ford control module to run the spark. was there a preference to this instead of adding coil drivers to the MSII or simply a case of "it's already there so why not use it"?

A) That's the beauty of the EDIS system, the controller is the coil drivers. You only need 2 leads to the MS, PIP and SAW

A) That was also my original plan but the folks at DIY Auto Tune and others
said no way, the signal will bounce off the damper and be erratic so it's on the outside of the pulley. Still have to work out a mount for the pickup.

A) That's the fuel pressure regulator, pump is mounted below the gas tank.

Hard to tell from the pictures but what are you using for a fuel pressure regulator?

A) See above.

The direction of the coil facing, is this a case of "that's how it was" or a best fit option? I think you are going to have a plug wire mess on your hands the way it is, plus the exposure to any fluids, debris, etc. I'd re-work the mounting bracket to where the spark outlets on the coil face to the rear. This would simplify the wiring runs. You could use the existing wire routing/looms also for a cleaner look.

A) That's why the bracket is mounted where it is, so the plug wires can utilize the original separators. As a side note, the Ford coil pack uses threaded pins like Benz so there was no need to make up hybrid plug wires. just shorten them.

Doing a great job, looking forward to seeing more of your progress.
Thanks.

Ahh, good explanations and the added photos helped.

This photo is the one which had me confused regarding the fuel pump.
Some actual progress.-100_1328_0089-2.jpg

On first glance it looked as though you had wiring run to what is probably a fuel filter. A closer look seems as though you had made an outline on the original photo and the "wiring" is actually just drawn lines. Is this the case?

The original wires are copper core with resistor ends. Do you think this will have any effect with the EDIS coils?

A) I can see where that would be misleading, the wires are for the injectors befor I attached the 6 pin connector. That's actually the oil filter.

A) Can't see why, the coil pack has built in noise suppression.

Smacks forehead in an "DOH" moment. The engine being out of the car and the shiny filter housing threw me off.

I guess you are using the standard MB fuel pump and filter arrangement?

Just wondering if the additional 1K Ohm resistance would have any effect. Don't see why it would, I was just curious.

Trying to post pics of a turbo manifold (not for a benzer)! Hopefully it helps someone.
