I found new Bosch injector nozzles $14 bucks a piece. Is rebuilding your injectors as simple as replacing the nozzles? Should you also replace the springs?

while you got them apart you should replace everything you can. where did you see the nozzles at? do they sell the shims to set opening pressures too?

What is the price of rebuilt bosh injectors at NAPA? I was going to get a set of the green cap "rebuilds" that are actually new.

??? What are green cap injectors???

Do you have a part#?

Green cap injectors are actually new ones that are being sold as rebuilt IIRC.

are they delphis or bosch at napa?

I'm confused:think: . All the green cap stuff! Anyways, why would you want stock replacements and not opt for a set that offers better spray for more hp and economy? Not tryin' to sound like a jerk, truely confused.

Several people (some who would know!) say HP injectors provide a minimal increase and not a good bang for the buck.

Even any increase would be better as they are not that much more expensive IIRC.

If you had a pop tester couldn't you just put in new spring and shims for less than $14 and get it right?

See! Someone who shold know!

NAPA "rebuilt " injectors for the 6.5 are new, (not rebuilt) if they have a geen cap plug on them. These are Delphi injectors. I have yet to see where hi-flow, hi- pop injectors have helped anybody. The computer controls the fuel quanity thru the injection pump. The injectors have no control over volume. If they did flow more. your fuel economy would go to crap.

Don't know what other parts they have. Guess no one has any info about rebuilding your own. Looks like I could save about 300 bucks if I just replace the nozzles.

Aren't 'hi-pops' selected from those that meet the high end of the spec, rather than just being anywhere within the (est) 1700 - 2100psi spec??

Here is some good reading on testing / rebuilding injectors. ;)

Easy to rebuild. Buy 8 new nozzles, 8 heat shields, 8 injector install copper washers. Reuse all other coponents. Adjust pressure with shims. .002" =~ 100 psi. Keep clean and don't mismatch parts. Mineral spirits should work well enough for cleaning. Nozzle number is on the tip.

Thanks, I found the nozzles, do you know where I can get the other parts you mentioned.

Here is a question. It looks like the new ones go for about $42 each. How much do those parts go for? Also how hard is it to get everything together right and set to the correct pressure? Looks to me that it might be better to just buy the new ones and put them in. For the amount of money compared to the time and effort to get the rebuilt right?

and do the napa injectors come with a warranty like so many of their other products?

The ones at the autozone had a 1 year warranty.

Won new Delphi injectors on Ebay and they were $255 shipped to my door. Haven't installed them yet.... Was a little disappointed at first because the seller's listing showed Bosch injectors and then sent Delphi but it still seems like a good price.

The high flow injectors make a nice gain in my experience. At least the ones that I set up do gain. While the computer does control fuel rate, the pulse width is backed down to get the same amount of fuel, along with the increase in ultimate fuel delivery potential...

I have the new Delphi stock units available also. I also have the install kits...

I'll also point out that one man's definition of high pop may differ from another's. I know this to be the case with some from north of the border.

You forgot about cleaning the carbon from inside the lower body, and lapping the upper body and middle ring.

Can you elaborate on this statement? What are your hi-pops set for compared to the ones i purchased north of the border here?

They work, better combined with other stuff & would be one of the last upgrades to do in my book after you have done everything else to get max benefit.

I didn't forget anything. This is the do-it-yourself -cheap-quick-way. Not a technical formal shop service procedure.

All parts should be readily available at your local fuel injection shop or one of the vendors associated with this forum.

Bead blasting the inside of the lower is something that really needs to be done. You may get by w/o lapping them, but the chance for leaks goes way up....

Still looking for an answer to this statement?

What's the nozzle that you use Kennedy?

I know it is not a luxury everyone has but I used an ultra-sonic cleaning tank that uses high frequency sound waves to remove the dirt and carbon. It is a $5000 piece of equipment at my work that is indespensible, better than a hot tank or a sand/bead blaster. My injectors came out like new.
