Technically the trap ox or its replacement "log" sit above the turbo. If the trap's been replaced, then there's now a cat that sits downstream under the car. Most traps have long been replaced by now.

ok... the "log" is there and so is a cat. I will yank it all when I go to 3" exhaust.

So is any one seriously looking in to the 7mm elements and IP tuning w/o send it to Finland? Because I am seriously interested.

If you are seriously looking in to good IP tuning with larger elements go for the original 6mm elements out of the 606 IP or better wait for the 7.5 mm elements.
I am trying to find s.o. with contacts to a good bench shop to be able to swap elements and do the (intelligent) adjustment in the US (there is already a potential possibility). External full load adjustment is not magic, I made it for my MW IP.
In my opinion this should be the way to go. Just shipping elements from Germany to the US not IPs twice.

Where do you think would be the best place to get om606 elements? Every time I see a 606 IP it's sold or a million dollars.

I fear a used 606 IP is the cheapest way to get Bosch 6 mm elements.

I've bin thinking about IP upgrade would these 7.5 mm elements work in the 602 turbo engine? and will any IP or diesel shop be able to install these? i would like more power but i don't know much about IP's so would the shop be able to just install them and then i could put it back in the car with out much ajusting on my part? i know i would prolly need to upgrade turbo, install a intercooler and well what else?
Thanks in advance!

That's the plan, yes.
The first sample elements should already be in the US. I work together with 2 guys for the swap and adjustment, they are in the Washington area.
Right now we are working out adjustment instructions for best results with these 7.5 mm elements. After the "lab rats" report back their results a 200 pieces production run will start.

Count me in for the 7.5mm elements in the future. I currently have 6mm units in my manual pump, but still have yet to fire it up. For me, the external max fueling adjuster is critical.

Good evening. I have been following this thread with much interest. I think I might have a shop that could do the work you're looking for. J&H Diesel Service in Greenville, Ms. I do not know if Mr. Harper still owns the shop(s) but all they used to do were IPs. Seems they do a lot more now. I was friends with his son Anthony while I went to college near there. They were good people when I knew them and answered many questions for me as my parents had a 1981 Olds 98 Regency diesel with an IP that was going bad.

Sadly, yes, if you want to go fast, the OM602 is not the best starting point. I'd consider swapping to something with an OM603 or OM606 if you want anywhere near 200hp. You'll have a ton of $$$ invested into making a 602 produce that much.

No dice. The 603 IP can only make 15-20% more power with the stock 5.5mm elements, or about 170-180hp at the crank. And that's optimistic. With 6.0mm elements it should be good for at least 200hp, maybe 220 maximum. I'm still waiting for my 6.0mm pump to get completed so I can find out!

And a LOT more power off-idle. The 602 is just sluggish until boost builds... not enough displacement to get the 3600-lb car in motion from a dead stop.


BTW - the 6mm elements are only found in 606 turbo pumps (606.962) so don't bother with the 606 non-turbo. Installing 6mm elements into a 602 pump should be good for about 175hp, theoretically. But you could get that from a stock 603 with the full load maxed out, for free, vs $2k in mods on the 602 with less torque.

Disclaimer: I owned a 1993 300D 2.5T for a couple years and sold it because of the low power. Great car, but the 603 version is soooooo much nicer to drive. And, the 603 comes with a stronger transmission that can deal with the increased power... dunno how long the 722.4 will hold up behind 200hp/250tq.

Was 1987 the only year the 603 was used in the 300d? was it used in any SDL's? Isn't this the engine with the cylinder head problems? My 602 in my 1992 300d was a rocket ship compared to the 617 i have now.

In the USA, yes, 1987 was the only year the OM603 engine was used in the W124 / E-class.

Yes, 1986-1987 300SDL had the 3.0L, and 1990-1991 350SDL had the 3.5L, both in the W126 chassis. The 3.5L was also used from 1992-1995 in the W140 (300SD / S350). Again, this is for USA models.

Only the original 1987 heads. If you replace it with the new style, the problem is solved. Many of the originals are still going strong though. Not all of them crack. The 3.5L rodbending problem was much more serious, and far more expensive/difficult to repair.

The 603 in the 1987 300D is much quicker than the 1992/OM602, especially leaving a stop, and yes they have the same gears. The 617 is a dinosaur by comparison. My 1987 300D with the full load maxed out would go 0-100mph in a bit under 30 seconds. My 1993 300D was closer to 40 seconds. The '93 did 0-60 in 11.5 seconds, btw, as measured via a RaceTech AP-22. So it was running equal or better to factory specs. More specs are in the spreadsheets on my website here. I'm hoping for low 20-seconds out of the 603 with the 6mm pump elements...
