2nd Generation Dodge 24 Valve Powertrain

In my down time lately I've been reading alot about injectors for the VP44 24 valve. Trying to learn and read reviews check prices and the like. I have looked through DAP and some others. Some look kind of "shady" or maybe that isn't the term but for whatever reason I didn't trust what they were saying. One on the other hand one seems to make some sense, Dynamite Diesel. All I know about this company is what I saw and read on their site and reviews of their products. I was just wondering if anyone has used their injectors? I did notice however that their prices are nearly double compared to DAP so I'm also curious as to whether or not it's worth it. .I'm not t…

Do the 24Vs have injector rattle? And under what circumstances does it occur? I'm getting a really loud pinging and panging, like a metal on metal sound, in low rpms when on the throttle. It happens from 3rd to the 3rd lock-up and 3rd to 4th. Right after the shift, the rpms drop to 1300 or 1400 and it starts pinging, but as soon as I get past 1600 or so rpm I don't hear it anymore. My fear is pistons hitting the valves, and NO, I haven't done valve lash yet. Any ideas?

Last summer I installed some 7x.009 (100hp) VCO injectors and have only put a couple thousand miles on them, slight upgrade from my previous 60hp VCOs. I have been getting a really loud pinging/panging when the the torque converter is locked and under load. Doesn't happen in 1st or 2nd gear and it clears up around 2000rpm when the turbo is really flowing. It's definitely coming from the motor. Anyone experience this? I was reading about pre detonation and it sounds like it. Only happens under good throttle and almost always up hill under load. Any thoughts?

Thinking about attempting to rebuild my injectors. Possibly trying to increase the power output a little in the process. Can't seem to find any good info on how to go about doing this. Biggest problem I think will be parts for them if needed. Any ideas?

Putting rv 275 in right now. Where is that thread that tells you how. Just need some torque specks for the injector holders. Little 5/16 nuts. Thanks

Im going to replace my 7mm nozzle gaskets ( 1.5mm) in my 01 Dodge Cummins, because i think one of them is leaking causing my rough idle at first intial start up. I have a question on the installation parts. Some people are telling me I should also replace 6 banjo connector gaskets ans 6 square cut o-rings. What are these two other ones? Do they mean the square cut o-rings are the connector o-rings? The banjo connectors I have no clue what they are, maybe one of you know what they are.

I made a post a few weeks ago about erratic miss at ldle. Well after adjusting the valves and remembering back I had this problem on a old eng. These are DDP 50hp injectors with about 5k on them and they run good but I believe there is something wrong in the injectors. I was looking through DAP site and my head was swimming, could not find what I am looking for. What I would like is 60hp injectors, bosh bodys , very little smoke. I mostly pull heavy tractors and don't want to break anything so just staying with injector hp. I had a set of 75hp years ago but to much smoke for me, I don't remember any erratic idle with those.

Ate all the shims in the injectors the same diameter? It seems [MOPAR][/MOPAR]like it.

I purchased a set of 75 hp injectors the DDP-ISB75 I don't know how that relates to the tunning of the Quadzilla adrenalin. are they a 7.010 7.012 or something else? Any guidance would be appreciated as I am new to the tunning world.

So injectors are currently getting re-popped to 325 and I've been watching youtube vids and write up on injector swaps. Obviously everyone does it a little different but I want to make sure I get things straight for my particular situation. As far as I know I'll be pulling on stock injectors and I don't know if/when a valve lash adjustment was done. When swapping injectors do I need to remove the exhaust rocker arms? Most videos show them being removed and I'm wondering since I don't think these injectors have ever been out of the truck if that'd be a good idea in order to verify the torque spec on the rear injector hold down bolt? I want to make…

So I got my RV275s in the mail today. I have a question on the removal of the old ones. I don't want to pull the lines off the pump end, but I got new O rings for the transfer tubes so they have to come right out. Can I just loosen the hold down brackets and gently move them out of the way enough to get the tubes out? I have checked the net and watched pepsiocean's video so I'm all good with the rest of the procedure, just not sure about the lines is all.

Ok so my slight miss at idle when fully warm is finally getting on my nerves. From my research it is most likely the injectors. I figure after 270K they need to be at least pulled and cleaned, and while doing this I may as well upgrade a bit. I am thinking of putting in RV275s. I do have a few questions that I could use some wisdom on as I have not played with injectors before. 1. Do I need to upgrade my fuel delivery system? Now don't throw stones at me but I still have the stock setup with the original injection pump. I have replaced my LP 3 times over the years and monitor my fuel pressure post filter with a mechanical gauge in the cab. Pressure is always…

Looking to upgrade over the rv275's that are in the truck currently if possible, not sure if I have the proper supporting mods to use upgraded injectors if I do. So heres the list, -quadzilla xzt -fass 95 -bhaf -4" turbo back -hx35 w/ ww2 (don't waste money on this wheel) -3 piece manifold would I be safe upgrading to 50 or 75hp injectors? Or would it be a safer bet just to stay where I'm at? I'm only looking to upgrade because what I have now are starting to haze.

Hello I'm going to buy new injectors will my auto tranny in my 2002 be ok with the rv 275 injectors i don't miss treat it just drive to work pull small trailer if so where best place to buy bosh injectors thanks.

Hello guys, I recently purchased a 2001 Dodge 3500 5.9 5spd to pull my equipment. My equipment weighs roughly 15k plus my 25ft dual tandem axle trailer. The guy that had the truck installed a 62mm turbo, 125hp injectors and adrenaline tuner. On level 3, the truck black smokes so bad that I can’t even see my equipment and don’t really build much boost until about 2k rpm. Took it to my mechanic and ended up having a cracked head. Ended up getting a new head, changed the tuner to a edge and still have the same issue with to much smoke and not enough power. Mechanic is suggesting to go with a smaller injector size. Any suggestions? Thanks

thinking this is the next upgrade i mostly take trips up to the hills tow the 20 foot seaox here and there maybe a trip tp canada to visit cousins.

So I was all set to give my girl a little more pep, and hopefully gain a few MPG's. My plan was to go with the rv275's but poking around here I saw a post from someone who got 60-75 hp injectors as an upgrade to a stock truck over the rv275's. My truck is bone stock, with an Air Dog 165 and new vp44 recently added. I seriously doubt I will ever put a tuner on the truck, so which injectors should I go with? She's got 330k on the clock and I'm afraid to do "too much" in fear of tearing something else up. Should I stick the original plan and get the rv275's or something a little larger?

I have ran a lot (3 sets) of 275's and one set of 75's and now DDP's 50 hp. And while I am on the subject I would like to thank JohnFax for loaning me his 275 till mine came back. John I will have them in the mail as soon as you can give me your address. Lost original box you sent.And I have to say the DDP's are the best I have ran as far as low end inj. They have a feel like no other inj. good low and good mid range. They do cost more but I think worth it. I am going to check to see if they have the same angle of spray or what they did, what ever it is I like.

Alright guys stupid question I got a set of 150 nozzles brand new the other day in a trade... my question is if I buy some new stock injectors and swapped nozzles would I still have to have them pop tested ......? my local injector shop charges a insane amount of cash to pop and shim injectors... just curious

So I bought the Quadzilla with Iquad and I been holding off installing it because I have a lot of lopping and to me too much black smoke with the 50 hp new bosh bodies. Dont know if the surging is due to this or not, I plan on sending them back to get them checked to see if theres a problem going on with them. In the mean time I though I would buy new crossover tubes just to have a piece of mind that they are good to go. Question is what injectors would you suggest to run for fuel mileage and towing with the Quadzilla?
