Very good write up with great pics!

Gonna try to order mine next week

:u: Your gonna love it jason. Its alot eaiser to do then it looks.

were can one fine these 3200 rpm springs you talk about ???:humm:

The easest way is to just call a Cummins or Bosch dealer and ask for part number 1-464-650-366

I just got a bunch of them in if you are still in need.

And don't tell them it's for a Dodge or else they get annoyed real quick...

I always ask for parts off an excavator. :yeah:

just give them the part number...

i installed mine today but forgot to mark the ticks, and i've tried every possible combination to make it right and it jus wont work. Any suggestions

Just keep playin with it, its got to be in that one perfect spot or it doesnt work. I did the same thing last week and took the throttle linkage apart 5 or 6 times before I got it. Good luck :c:

runs like a commonrail now

Good, I was scared as hell when mine didn't work right but kept playin with it and its good, but my throttle shaft is leaking a lil bit now so I get to take it all back apart and do it again :humm:

I just ordered mine online earlier this week. much faster than the Bosch dealer could get it to me, and cummins bridgeway shop told me to go elsewhere to find it :madd:

I think if it shows up i'm tearing into the pump tonight yay!

I have a bunch in stock. let me know if you have trouble getting them

how much?

Just a heads up before this goes any farther take talking price to PM's please. One of the few policys we have! :U:

And Coco you will be very pleased with a 3200 spring!!! Well worth the low cost!

Just got mine installed. took about 3.5hrs cuz it took me forever to get the idle screw out of the way, it seems bent and wouldn't come out :( but anyways.. wow what a difference!

looks like a lost a lot of black smoke in the process :humm: but hard to tell at night.. looked kinda more grey in color when i got on it.

well before long i'll be able to say my truck has a new set of nuts under the hood... adding the spring to the parents order for an upgraded trac bar kit for their truck... i covered their fuel filter and fixed the fuel leak so we're going to call it even :yeah:

You will love it.. I know I was a bit skeptical of how much it would give me.. but nice!

here's what I noticed:

snappier throttle response.
smoother idle and less smoke (not sure on this but its acting like it has less fuel)
pulls really hard at the top end of the gears when the turbo is lit, like 2x difference third now pulls like 4th used to (for the g360 owners)
crusing at 75-80 on the freeway isn't killing my foot keeping the pedal down.. more like 1/4 pedal left AND very responsive with power to pass.

Those that feel like they lost a bit of power and smoke up top its probably because you are pulling your lift pump down to 0psi now.

lol yeah... about that... i'm sure an air dog will need to be in the works...

seems to have top end power. just lost some bottom end..

guess I should throw in a better pump anyways.

Did you do any other changes?

None at all. the only change was a slight adjustment of the idle since it was way to low when i set it back.. I think I added maybe 1.5 - 2 turns to the screw from where it was to get back. Fuel filter is good, just changed oil.

it's not a huge loss, feels like a bit more turbo lag honestly, it'll smoke but it cleans up faster than it did before the spring. i'm prolly due for a lift pump upgrade anyways.. and looking for a better clutch before this one comes apart.

way low after the spring install? if you didnt mess with the idle screw everything should have remained the same...

I got the idle screw almost off. i was gonna shorten it and install the screw side to the front for clearance to the pump housing bolt. I had it marked but couldn't ger it out.. it's a little tweaked like someone pried on it or somethin *shrug*

thinking about it. my issue is the grind I put on my fuel pin. it's very light then dipd hard.. so at lower crusing boost levels it's not fueling hard and saving me some fuel since I mainly drive highway. If i put the bottom end a little more agressive it should fix my issue.


i'm good. lol

lol i just angled mine relative to the factory profile and pushed it into the bench grinder...
put a slight curve to it... maybe... lol then i polished up the surface and wire brushed the crap out of it... i does ok :w2:

I'd hate to bump an old thread But i have a video now which helps with the 3200 Spring install alot.

:U:
