I tried the bosio nozzels for about 6000 miles. I'm running a turbocharged 77 240D at about 9 pounds of boost, so my experiance may not apply to an unmodified engine.

I set the nozzels up at 135 bar with my pop tester. The spray pattern looked good, so I stuck em in. At first, the engine sounded better, smoked less, started easier, and got better mileage. All miles are highway miles at 65 to 75 mph. The car is litterally started, driven 155 miles, shut down, started and driven 155 miles home. After about 3000 miles, the engine started nailing when it was cold. Not bad at first, but it got worse. By about 4000 miles the engine would nail when warm!

I ran some Power Service through it for a week to see if they would clean up, but the results were marginal. By now I had about 5500 miles on them, and the engine sounded horrible! Smoking, hard starting, and nailing.

At 6000 miles, I had had enough. I pulled the injectors and re- pop tested them. The pop pressure was fine, and they did not leak or ooze, but the spray pattern was CRAP! Most of the fuel seemed to spray out one side of the nozzle and formed course streamers rather than a fine mist.

I am not impressed by how quickly the spray pattern went to !@#%&!

Anyone want to buy a set of Slightly used Bosio nozzles? Cheep? Anybody?

I might have had better luck in an un modded engine, but I don't see how the turbo would affect the spray pattern.

Just my 425 cents!
