Hey all, been a long time since I have posted since, with all the help and knowledge here, I was able to get my 98.5 going just how I wanted (at least within my budget), so I have just been driving and enjoying it. Its looking like it will need an ECM (code), possibly another VP44 (the fass gelled a few times during warm up and I think the VP took a hit from that), and a steering gear box... Well mamma started thinking she might just get her a pickup so that I wasnt rushed to get the 98 all doctored up. Plus now having a 15 mo old tricycle motor on the ground, the single cab wasnt very user friendly.
She ended up with a 2005 - 2500 Quad cab SB. One owner rig til she she got it. Previous owner has some stuff done/did himself - so Im in the process of learning and becoming familiar with the 05 and common rail setup. Runs good, feels good, and I think she got a good price on the pickup. Anyway, that puts me here, searching and researching, and I thought I would at least post up about the pickup, and open my ears to any thoughts,insights, and opinions from everyone here as I continue my learning
Here are its stats:
'05, 2500 Quad Cab SB, NV5600 6sp, Cummins/Jacobs Exhaust brake (vacuum actuated style), Banks Monster Ram, boost and pyro gauges, 3.73s with 275/65-20s, and had 76300 miles when she got it.
Im surprised considering the add ons, why there wasnt an aftermarket air intake setup, or cat delete or what have you. But it is what it is.
Here are some of the questions Im currently searching/researching in case anyone wants to chime in. I have open ears and eyes
Fuel mileage isnt where I was hoping it would be (16-17MPG) - compared to my 98 - but it took injectors, a smarty, AFE intake, and 4" exhaust to get to the 20MPG it regularly gets now.
So Im looking at the options to help bring up mileage, and of course no one complains about more umph. Was planning on a Smarty first thing - once I can figure out and understand all the different versions of the S06 (Revo-TST-etc) since Im not used to all the choices compared to when I got my S03. As far as I know the clutch is stock, so I need to be mindful of that being a real possibility (as I cant think of any way to find out otherwise without tearing it apart - and I dont need that kind of investigative project).
And at the price of injectors, I think Ill wait to do something with injectors, as it seems that that's sort of a common thing on these at some point before 150k miles(??). So I think starting with the Smarty, and then start looking at other options. Im open to ideas here if anyone wants to share opinions.
Ive read about adding additional filtration to the fuel system... is that mainly for CP3 life? Injector life? Something else? But better filtration always seems like a good idea to me.
I know the lift pump on the 2nd gens was a big thing and went with a FASS95/95 on my 98. How big a deal is this on these common rail motors? Its a notable expense, but I know how much peace of mind it brought with the 98 - so if its a smart idea to do on the 05, Im game. Is a fuel pressure gauge as big a thing on these as it was on the VP44 motors?
The cummins/jacobs exhaust brake seems lacking... to the point I didnt think it was working when I test drove it for her, come to find out, its operating, but I dont feel it kick on, ever. Anything to do there to make it more effective? or just nature of the beast? Probably wont spend the money to change it out to an air pressure ran one, but might consider down the road if the vacuum operated one is just a joke. I need to get a vac gauge on the line to see what its pulling down to - maybe the pump is on the way out and why it seems ineffective. The manual says 15-29 in/hg which seems like a sort of large spread... but maybe its not easy to overpower the flap and a non-issue.
Does an aftermarket air intake make much difference on these? Seemed to help a lot on my 98, but the intake tube on the 05 is a lot bigger than it was on my 98. Not looking to waste money on something that doesnt do much.
Boost gauge on this will get up to 35-37psi, then quickly drop to 30-32ish - is that the normal range on these? or should I be looking for a boost fooler installed somewhere? the 98 would defuel at 20psi until I went to the smarty - now it runs up to 32PSI. Not wanting to push too hard on 'er - no desire to mess with a blown head gasket etc...
I think those are the main things Im researching right now, but Im sure Ill come up with more as I go.
