For normal operation, I will be using the NB o2 sensor. When I am tuning, I will be using a WB 02 sensor. (I have three MS projects in the works. so, it will be shared amongst them.)

This is just a quick MS project. There are long term plans for the car, and it will be in stages. This stage is just "what is the quickest and easiest to get it working."

Stage 2 will be more toward MPFI. More than likely, not with this engine. Part of the reason, for quick and easy.

When I am done, I will post the complete cost.

Since this car never has had EFI, I used a relay board. Again, don't forget there are future plans, and I have tried to keep it open ended to allow for changes and other addons. (Possible turbo later.)

For the moment, I am stalled. I can't find the right intake manifold. I missed getting the right 240D intake. Actually was trying to remove it, and didn't have the right socket. Went back and it was gone!

So, I am waiting to find one.

Thanks for the inputs.

Ah, I understand now. NB would be a pain for tuning but it should work fine for driving after you have a solid tune. I hope you find the right manifold.
good luck with the project

Thanks for your input. I do appreciate comments. Rather catch a problem now, and save time and money!

Scored: Found 240D intake

Finally got a 240D intake at the local picknpull: $35.

Ok. Here's a couple of pictures. One shows the area I will need to adapt the GM TBI. I am thinking I will need to open this up a tad. You should see the size of the throttle body that the 240D comes with. Literally breathing through a straw. :O

The second picture shows the head side, with the 200 gasket in place. Looks like it will fit. I do wish it had just a little more boss-area to mate to the head for good sealing. If this doesn't work, I will be fabricating a manifold. Out of scope for this stage. This stage is cheap and dirty EFI for the MB.

Very cool. From the pic it looks like the diesel ports are smaller than the gasser gasket?

yep. much smaller.

There is a fair amount of material, if I want to get busy with a grinder. Right now, just getting it work, is the first step.

So, i am expecting to lose a bit of hp. The next stage will get it back.

Just small update:

Been too busy with my other projects to get anywhere on this. Need to get the starter installed, and find a good distributor to trouble shoot why the car will not start. (The old started died with all the attempts are starting the car. ) Looks to be something wrong with the ignition.

Anyone have a spare disty??

Scored a disty today from the Fremont PnP. Hopefully, it will work.

Now, I can make some progress again.
