7mm injectors in my 9mm head

7mm injectors in my 9mm head
As I'm reconditioning my 1991 6BT replacement engine I pulled the injectors to inspect them. They are in great condition and came out very easy, there was grey anti-seize on the nut threads. The problem is, they are 7mm injectors in the 9mm head, without the adapter/washer. The engine ran good but I don't want to put them back in as they were. The injectors are stamped/etched "Delphi 680 1127 DZM". They have 4 holes in the nozzle.
Are these the Lucas 300 POD's?
Will they work if I just purchase some 7mm to 9mm adapter/washers?
I'm putting the turbo and intake manifold from the intercooled engine onto this non-intercooled engine.

yes they will work with the adapter washers.. I will look to see if I have a set... the turbo off the intercooled is bigger... use the turbo off the intercooled but with the 18cm exhaust housing off the non intercooled.. most likely your intercooled engine has the 21 cm ex housing and they suck. there stamped on the back.18/21

I'll PM my address to you for shipping the adapters. I still have the old 7mm injector you sent and will get to using it to test my bad engine as soon as I get this one running and installed.
I'm not totally understanding your suggestion about the exhaust housing. Are you referring to the exhaust manifold or the exhaust housing portion of the turbo? If it's the portion of the turbo I'm not sure how to change the aluminum part of the turbo. Is it a simple swap?

yes the exhaust housing of the turbo... most are 21cm intercooled. some are 18... BC may know what years are what on when they used them. there stamped on the back of the turbo... I just found your phone number I think I have a old 18 laying around.. the 21cm lag bad..you will need penetrating oil and take out the (4) 13mm head bolts to separate the turbo from the exhaust housing.. or you could just put your intercooled comp wheel and housing on the non intercooled 18cm housing... its a little work but trust me its worth it.

O.K., I got it. I'll look for the cast/stamped numbers to see if one of the two I have is the 18cm housing. I'll probably do the work this coming weekend.
Another question on separating the turbo from the exhaust housing....will I need to take the intake side impeller off the shaft? I've only taken apart one turbo and it seems I had to pull that one off to get the aluminum (intake side) part of the turbo off.

I know what you mean about the lag. The intercooled engine I had in the truck (the one the KDP killed) had a definite lag. I don't have a tachometer but it probably didn't generate boost until about 1,400 rpm.
I'll look for the adapters.
Now I have the option of putting in the original stock Bosch 7mm injectors with 6 holes in the nozzle, with the holes drilled to spray an even pattern into the piston depression, from the intercooled engine or the Delphi (LUCAS?) 7mm injectors from the non-intercooled engine.
The Delphi ones are in excellent condition. They have the 4 holes at the tip and based on what I've read on this site and others seem to be the LUCAS 300 injectors generating an additional 50HP. The only problem I see is the spray pattern from the nozzle holes isn't correct. It doesn't seem the spray will be directed into the piston depression.
The stock Bosch injectors need to be cleaned and pop tested and possibly rebuilt with new nozzles, but I like the nozzle pattern.
Another option is to get some new injectors from a place like Oregon Fuel Injection. There site and price list is here: Dodge Cummins diesel fuel injection pump, VP44, injectors, turbo, turbocharger and turbo parts
Any suggestions on this? I don't need a bunch of black smoke. I just want good power, good mileage and excellent reliability.
