the end cap is replacable - its called a pintle cap and I buy them by the bag (100) for a dollar each from dr injector or somewhere similar. there is a long nylon mesh basket in the top of the injector which should also be pulled and cleaned
I am currently converting one of my megasquirted engines from the bosh 036 injectors to the 290ml JECS injectors off a couple of nissan zx300's. remember with the nissan injectors that the number on the body is a date and production facility stamp and does not relate directly to flow rate. flow is determined by the colour of the body not the number.
there are a couple of pics below of how I do it but I use mt stimulator to fire the injectors and you are playing with gasoline under pressure and the possibility of electric sparks!

Hi Barri
I am impressed because I know you are a pioneer.
I am also interested to learn this stuff. On the other hand I just don't have the time to figure this all out.
If I go the way with the GB reman. injectors (I guess these are Bosch ones) then do you think there is good chance that a set of these would work fine?
If yes this would be the easy fall back option.
on the other hand the car was running ok..not great...with the old injectors. But I don't have the comparison. So if I decide to do the experiment would you sell me the parts I'd need to do my own remanufacturing? Do you think I can make my old injectors work...if I just have enough time? How do you adjust the flow rate on your injectors?
(I have built my own diesel injector stand for my SDL Diesel years ago and it was a great experience. However the gas test stand seems to be more challenging/dangerous and stinkier)
Third option: Do the Nissan zx300 ones just go straight into the Mercedes 3.5?...even with a different flow rate? Or can the engine handle different rate if the set is the same flowrate? New Nissan injectors are very cheap on ebay...like $140 for 6 injectors
