I need a new set of injectors, I have a 1995 12v Cummins that was loved by a old man that kept up on everything, it has original injectors in it that have 270k on them! I want a set of injectors with a little more power, something that will make the truck a little quicker, I just don't know what kind I should get someone help quick!

 

Have you done any pump mods/tuning? Stock injectors are capable of almost double stock power.


FWIW my original injectors have over 270k on them and make good power, enough to peg 1600 pyrometer, outruns my 07 w/325hp too.

 

No I havent, but this may sound childish but I would like to have some smoke every now and then but I'm a little new to this diesel world, and I know about the fuel plate and I'm planning on removing it or grinding it, and I know how to do the star wheel, I would just rather do all that after I got an idea on what injectors I was putting in

 

What I think Gorms is trying to point out, there is LOTS off power to be had just tuning the pump.
Injectors might be un-necessary mod., and depending on what is picked it might just lead to a smokey mess.
I would start with cheap/ free pump mods before getting to injectors...

 

Well what pump mods can I do? Can anyone help me figure this out?

 

And I also want a little smoke, only when I get after it. You think maybe 3k springs would help?

 

3 K springs will not add smoke.
Sounds like a little reading of some of the treads in this section, would help you out.
Grab a beer and read up.

 

3k springs are a must, IMHO. Gauges, pyro and boost minimum. Then a fuel plate either removed or ground to whatever you like. Adjustable boost elbow to set the wastegate back to 30psi, or pinch the line off completely. Spend a little time researching how to tune the afc for your needs, and dial it in. That should be enough to slip a stock auto with 270k on it, may want to look into at least a shift kit and band adjustment if its an auto. If standard, stock clutch will be the weak link.

 

Well I did forget to mention the tranny has been replaced at 250k so it's not too old and I know these dodge autos weren't the greatest things around. But the Pyro gauge, boost gauge, and transmission temp gauge are being shipped and on there way, ordered them 2 days ago. But I have been reading about the star wheel and people say you can turn it 20 clicks and some people say no more than 4. What are your thoughts on that?

 

215 injectors with proper size copper washers. More timing and 3 k governor kit washers .
