Which in itself suggests that the monark are a closer facsimile to the original, and that the bosio are not....(Just why is it, that bosio recommend the same nozzle for a variety of engines, where Bosch had different models for each...!!??)

Side-cut Pintle-nozzles like these in the Pre-chamber are tailored to their use. Practically any nozzle of this type will Work in there, but have differing torque characteristics at different speeds....(And be a vast improvement over some 20 year old 200K milers taken out!)

Another reason why I am interested in the TYPE NUMBERS and not MAKES that have been used....

I am not sure the type number is as helpful as you think. When I first got my car I bought some Nozzles that are labled DNO SD 220. However, this does not mean that it is a Bosch Spray Nozzle. It is a Brand X Itlian Nozzle made bye 7 Diesel (at least that is what I was told).

I the 5 years I worked in a Fuel Injection ship I saw the quality of Bosch Nozzles fall. If I built 6 Injectors I would get a variance of excclent to barly usable concerning the the seating area of the pintels in the Nozzles. Mainly meaning that a fair number would not met or barely pass the holding pressure test and drip more than the should.

I got similar results when I rebuilt my Volvo Injectors with Bosch Nozzles in 1992 and later in around 97 when I rebuilt them again ($11 each and Bosch made in Brazil).

In fact Bosch changed the specs back then to allow more of their dribbly nozzles to pass (this kept me from sending them back to the supplier like I did before the spec was changed).

I have built 2 Sets of Injectors with Monark Nozzles. All but 1 Nozzle that had a slighly feathered but OK spray pattern were all excellent and consistant.
The Brand X 7 Diesel Nozzles teste out as well as any Bunch of Bosch Nozzles I have tested in the past.

In any event I am not convinced that Bosch makes the best quality Spray Nozzles. But, where I worked we used a lot of them as they were cheaper.
During the same time CAV, American Bosch, Bryce and Diesel KiKi (Japan) made what I consider better quality Nozzles.

Took the words right out of my mouth! Additionally its tough to get into a discussion of fuel injectors without hearing about Monark or Bosio. I have heard many success stories for each brand, and just as many "failure" or clog remarks about Bosch. Bosch has (allegedly, I can't vouch for sure) transferred a lot of their manufacturing to India, which has negatively impacted their quality, or so I have heard.

I had to revise my post and remove that part concerning the 603 as he said he was experimenting 617 abd 603 and the DNO SD 220 is used in NA 617s. My mistake for not remembering his origional post clearly.

Bosch injectors and nozzles for the 80's MB diesels have been made in India now for years. If you choose a Bosch injector from Fastlane, it will be from India.

A few years ago I ran across a supply of Bosch Made-in-France injector nozzles for the Turbo cars and snapped them up. They are not available any more and represent the original OEM quality.

I have enough to rebuild all my injectors one time as they need it. I have sold most of the rest of them to people here for $50 each plus shipping.

If anyone reading this thread wants a set of French Bosch OEM nozzles to keep on hand for the future or to use for a rebuild, please send me a PM.

That was my mistake too, though I didn't know the part number....I thought he was going between NA and turbo injectors. My bad. I do still think that monarck and bosio should be considered in this discussion though.
