Well it's official

Lamont_24 · Feb 9, 2013

I'm officially going to mechanical, I'm trading a friend of mine my engine and transmission for a ve pumped cummins and nv4500. I'm gonna miss having a damn good motor. I'm planning on making about 350 horse with the ve pump and maybe down the road p pump it. I just want to thank everyone here for the help they've given me with my truck

Bobby@cp · Feb 9, 2013

For 350hp I wouldnt do all that work, prolly cheaper and easier do just do a set of injectors.

id stay away from the VE pump rotary pumps are no good, look at the 6.5 pumps and the VP44 and the like. If your gonna put a cummins in it, either go common rail or the p pump

bad12jr · Feb 9, 2013

I have almost 350 with a set of stock a ad's in an obs. No way I would make a swap unless I was shooting for 600 or so and putting in a commonrail.

Well my 7.3 was getting pretty tired and my friend wants all my aftermarket stuff so that's basically why I'm doing it. With my mods on a good motor it would be 350 to 400 horse I bet. My engine had lots of blow by, like lots. It's basically shot. And I'll enjoy going back to a manual. But I might be able to do a p pump conversion for free because a guy who had a white tractor had us put a cummins in at work wanted a ve pump for fuel mileage and so if I can talk him into swapping parts it would work out well. I'm also looking to get good fuel mileage, with the ve I should be about even with what I had before which is what I'm looking for

With the time and money required to do these swaps. And I don't care if you get a whole engine for free. Its be better to rebuild your 7.3.

So your gonna put a possibly whipped Cummins in place of a whipped 7.3?

You should rebuild the Cummins before you put it in anyway. It'd be a shame to do all the work to find the engine is toasted.

Then again rebuild your 7.3 and keep all your goodies you have on it and you'll still be less in it than a Cummins swap with a rebuild on it and the performance goodies you have to buy for it.

I know I sound like a complete dick but I'm trying to get you to think into this before you go diving head first. You can't do a whole swap in a weekend. Can you afford to have your truck down for a minimum of 2 months or more?

You can do anything you want, as long as you don't break rule #1

Oh I know what you mean. My close friend and I just finished a cummins swap for his girlfriend and I've helped a little on another one. It takes time and effort and money. I know what you mean about rebuilding my 7.3 and the only thing is, is that if I want to go bigger down the road it's going to cost a lot more. Cummins can make cheap power is basically why I'm doing it. I mean yeah, my 7.3 could make good power with a fresh motor and be badass, but I've always had a soft spot for a cummins. Not dodge, just cummins lol but I appreciate your input and I will probably take your advice about rebuilding the cummins because it is the smartest thing to do. And this truck technically isn't my daily driver, it used to be until I ran into problems with the turbo and trans and then I started driving my winter beater. Thanks again for the input sir

Sounds like you have a plan. I just wanted to make sure you had it all thought out. I've made That mistake before and my Camaro is still up on stands 3 years now lol

Just fyi, the VE pumped cummins are VERY hard to get power out of compared to p-pumped. Rotary pumped cummins brag about 250-300whp when 'turned up'.....

Also, keep in mind that not only is hp very, very peak in a mechanically controlled inline motor (yes, you MIGHT hit 300hp... for 150rpms...), an electronically controlled v8 such as the PSD with the same power level has a much flatter power band (read: more power, faster). Also, those 12v are very hard to control the heat when you start putting down more power. Basic mods (not including injectors) and you'll be tagging 1300*.

Also, keep in mind that the cummins you have starts off @ 160hp compared to our 225hp.

Lamont_24 · Feb 11, 2013

Yeah I'm aware about the ve pump crap, But that is good info about the power curve, I never thought of that before. And I used to hit 1600* wot with my 7.3 with stock injectors

If you were hitting 1600* on stock sticks, time for a new tuner. I know of people running 400+hp on bigger injectors that keep egt's 1200-1300* tops.

FrankTheTank · Feb 11, 2013

I have a 80hp PHP performance tune.... unloaded, i CANNOT get over 1100 at WOT climbing a hill on stock sticks.

Lamont_24 · Feb 11, 2013

Idk what it is, it might have bigger injectors, but I've never changed them. When I bought it, it was the kids grandfather selling it but it didn't run and he didn't know anything about it other than they pulled it to put a cummins in but decided to put the powerstroke back in for some reason but never completely finished it. It had an adrenaline on it when I bought so maybe it has injectors. But I like to think of it as destiny of this truck to have a cummins in it since the previous owner never finished it. But I might have a chance to p pump it before I stick it in for free so that would be a plus!

85_305 · Feb 11, 2013

Even if its p-pumped... they were still 160hp motors (depending on year), and had terrible curves due to being mechanical. Mod vs mod, the 7.3 would have been in front of it.

Lamont_24 · Feb 11, 2013

Oh yeah I totally agree with what your saying, but when your talking mod vs. mod youll be spending a whole lot more on the powerstroke. But like stated above the power curves are different. I used to say "you got to pay the cost to be the boss" whenever a cummins guy talked about how much his modifications were compared to a powerstrokes

Lamont_24 · Feb 11, 2013

Now you guys got me thinking haha but if I pull mine and rebuild it, what do you think I would need to make 400 horse with it? I've got an adrenaline, 66mm turbo, irate diesel fuel system, and a ts but Id get custom tunes, right now they're canned. And I'd get my injectors tested to see what they are, but what injectors would I be needing?

fordfreak4life · Feb 11, 2013

Not a 7.3 guru but 238/100 should get u there with existing equipment

Not exactly... parts for the 7.3 have gone way down due to recent discoveries in the past few years.

400hp on a 7.3 is custom tunes, stock turbo and some 160/30 nozzles. Thats 400hp all day long. Sticks are $800 and good tuning by BPD is 400$. All the cummins guys I know modding their 12v have bigger injectors and bigger turbos just to make 400whp, and they are smokey, run hot, and of course... **** power curves. This new gen-II wicked wheel looks promising too... seen 20-50whp gains just by this $260 wheel for the STOCK turbo. I'd say 420whp+ is possible w/ the genII, stage 1.5 injectors, and intake/exhaust/tuning.
