You're right about the angle, didn't think about an inter cooler till you mentioned it, may very well have had an inter cooler...

The guy said it was a TPS, I don't know for what though... maybe the tranny? There's a rod that goes through the IP and to the sensor, it coincides with throttle input.

Yes, it's just a recess... couldn't poke through it. What was the control rod sensor for?

Should I try and install an intercooler? There may be space for one I'm not sure.

The 95-99 S300, a W140 with a turbo 606 not sold in the US, had an intercooler.

TPS might be for an electronic transmission.

Nice, where was the intercooler mounted... gotta search the net for that one.

I know of 1 W140 in the US in which the 603 was replaced with a turbo 606 from a W210 complete with body and bumper modifications to fit the W210 intercooler.

The control rod sensor is used by EDS to modulate EGR and ARV based on this surrogate for engine load... or something like that. All it's good for is leaking from an o-ring that can only be replace by tearing apart the IP.

MB went with inclined injectors to improve performance, reduce consumption and emissions, yadda yadda... IIRC the first US application was the '87 190D turbo. Other US 190Ds have vertical injectors. If not the '87 190D turbo, it was the '90 300D 2.5 and '90 350SDL. The prechambers are different to accommodate nozzle holders with different thread pitch and location - fine and by the firing end vs coarse and further up in vertical injectors. The injector lines are a little bit different as well but some folks bend injector lines for vertical injectors to fit inclined injectors. Glow plugs are different between inclined and vertical injectors so make sure you get the right ones.

Thanks for the info... so its an improvement? I hope there's less noise besides all that. I have a stash of glow plugs and injector nozzles for the 87 wagon that I never got to use... and will never get to use.

As far as I know everything is improved with the angled injection.

The "gap" on the 603 is 6 bolts wide... mounted on the w140 this clears the rear cross member and the steering links/damper...

On the 602 however... this "gap" is only 5 bolts wide... so as Sixto has pointed out, the tranny will have to move forward, and the trailing edge of the rear crossmember will have to be modified.

M104 sump

However... curiosity got the better of me so I took a picture of the m104 sump that came from the car... it also just had a 5 bolt wide gap... similar to that of the 602... I do hope I don't have to modify the crossmember...

Do you have an oil pump and pick-up to work with the new pan?

Sixto

Yep, I ordered the pickup tube with the pan. Didn't think to get the oil pump... should I have? the oil pump is easy enough to source here I think. I hope.

Is it possible that the M104 gasser sump will bolt to the 603?

Not really sure... but I do remember reading somewhere that it was possible. I could be wrong though. Would've tried it if I had a 603 to install.

Likely. I had a 603.971 that came to me used with a 104 prefix part number. I'm not aware of an M102.5 though
