Hey guys! First time post long time reader.
First off I'll give some background on what I have and what I want to do.
I have a 06 3500 mega cab. I'm looking for some more power (who isn't). It's has 120xxx on it now and I had a injector go. I replaced it but now I'm going to do them all. Which brings me to nozzles. I'm looking for a fun truck that can still do everything (tow, road trips, just cruise) and have some usable power. I occasionally take trips from MA to SC to see family. I'd like to not have to worry about towing (10,000 or less). Don't really care about mpg that much. I'm averaging 20mpg now with very mixed driving.
I was looking at 50hp nozzles or 90hp ones. I'm going to buy new oem injectors and swap out the nozzle. I do plan on getting a a banks intercooler kit and a fleece cheetah and stopping there. Not sure if the "bag of parts" for the pump is needed? Not looking for a smoke show. It's not bad now, light smoke under heavy throttle.
What do you guys think? I know it's kinda a small build but I want to just do it once and be happy.

Any help would be appreciated!

I tried to edit my signature but not sure if it worked..

Don’t buy oem injectors and swap nozzles yourself. Contact S&S or Exergy for a matched and tested set of injectors. Being that you don’t mention a turbo in your future, you could go with 50 or 90 hp injectors and not get to hot for the turbo. If you have any inclination to go for more HP, go with 120 injectors and custom tunes from EFI live. Have the pulse width dialed back to keep rail pressure from dropping off. Either way ditching the Banks and going to custom tunes will give a major boost in HP and drivability when doing new injectors. Not a mix match set made in the garage.

Don't swap the nozzles. Just get some bigger injectors from exergy, S&S or bbi. Instead of a new intercooler that won't give you any noticeable difference, get rid of that banks box tuner and get custom tuning instead. The fleece cheetah isn't a bad option, but look into the SXE turbos before you make your purchase. Also the bad o parts is garbage.

My concern with buying injectors already setup is that they are reman. Vs I can buy brand new bocsh ones and put nozzles on.

I'm not going for big hp numbers. I want a drivable truck that I can tow or drive anywhere. That was one of the reasons that want to do the intercooler kit. Not for power just more reliable power. Keep egt down.

If your intercooler has the plastic end caps, an aftermarket intercooler can be more reliable. The plastic end caps can crack, but i haven't seen it be a big problem. But other then that, it's going to do nothing for you. Custom tuning will be able to control your EGTs far better then an intercooler. bbi uses new injectors and im pretty sure S&S and exergy do as well.

Not really sure about the trans, shifts fine. It's not original to the truck I don't think. I have a new vb and bd solenoid kit on the shelf waiting to go in. Maybe over the winter I'll pull the trans and get a rebuild kit.

I'll have to check out those new injectors. I've had bad luck with remans. So I'm definitely going new. So I guess the question is if I get them with nozzles or put them on myself.

After more research I'm going to do 30/33% ones.

A better intercooler and pipe will help overall with everything. Power is in air density not boost. Make more power with less throttle keeps everything happy.

As far as custom tunes. That might be down the road. For now I'll stick with the banks. Like I said not going for crazy power. Just a good all around truck. 450-500whp is max for my goals.

Grunt is basically saying our stock Intercooler is awesome. A new aftermarket cooler won’t improve anything for your setup. Just trying to save your money is all.

Also stock new injectors will get to your goal. But a 30 over will do nicely. Exergy has 30% overs brand new sets for about $3200.

That's not true. But if you wanna spend $1000+ for some parts that you won't feel any change from, well thats up to you.

go with the bosch motorsports 50 or 100 hp with the spray angle you want, opinions on this vary wildly so read up and make your own choice. These are new injectors btw so nothing to worry about. Exergy sells these as do others for the same money as a stock size set give or take. definitely go new tho.

I understand that I won't gain anymore power but I'll be able to move more air easily.

I have it narrowed down to s&s or exergy. It's about $1000 more than stock. Now I'm not sure if it's worth it if I don't need the extra fuel.
I read alot that even on stock setups larger injectors help. I'll have to do some more research and get some more input from everyone here.

My thought was for $1000 I get a bigger cooler, larger pipes, and a better intake horn.
My intake air Temps are usually 10* or so higher than outside temp. I appreciate everyone's input and opinions. That's why I asked the question. I like to hear from other people and their personal experience with products.

I did see these mentioned a few times. It seems to be very mixed. A lot of people say that they will melt Pistons. I don't see that happening unless you put a crazy big one in or when with the wrong angle. What I like about the other two I mentioned above was they keep the factory angle and hone out the holes to make them larger. Some of the other nozzle companies give you new nozzles that might not match up to the same angle as Factory. I will say one thing over the past couple weeks of doing research on injectors there is definitely a lot more to it than I originally had thought. I'm glad I didn't just go on eBay or something and by the first set of injector nozzles I saw.
Do you have any personal experience with the Motorsport injectors?

I have the "BMS" 50HP marine injectors. The only complaint i have about them is they haze a little. Other then that, they seem to work great. The next time i need injectors I'll be looking into S&S,exergy and bbi. Those 3 are one i recommend for injectors.

Intercooler, pipes and is going to do nothing substantial and would be a big waste of money. For the money you'd spend on all those parts you could get custom tuning and that will benefit you far more then then those other parts. steve has done some testing with IATs and shown his fuel mileage is better keeping the IATs around 100°+.

Really? I always figured the colder air would be better. I have rather limited diesel modification experience. I'm coming from turbo gas engines. I have 2 kits ts of water/meth I've been tempted to use. Not sure how diesel engines act with it. I know my 2 liter i4 loved it. Used a wot switch and psi switch. Kit turned on at wot and 30psi. Worked wonders.



I'm just trying to justify spending the extra 1300 on bigger ones over just putting new Bosch ones in. I'm either going exergy 30% or stock Bosch.
Will there any major downside to running the 30% on my setup until I get a new turbo?
My plan was turbo then injectors but plans changed when the Injector went out.

Haze isn't bad, I just don't want to be rolling coal everywhere I go.

where are you getting new injectors that cheap?

Guys do run water meth systems in their pickups. I haven't really looked into them that much because i don't have a use for one. The horror stories (not that it's common) of them leaking causing hydro lock doesn't make me want one want more. But i guess you could always put a manual shut off valve in the line

The injectors are the heart of the engine. They can make it run great or destroy an engine pretty quick. Injectors are not something you should go cheap on.

30% overs will be fine with a stock turbo. Tuning will play a bigger role then a turbo when it comes to how clean it runs.

Upgrade/Rebuild that trans, get efilive. And youre done. No injectors needed. If u must get injectors, go with bbi. If u just want stock new bosch, 2000$ from injectors direct. I wouldnt put nozzles on new bodies, not worth it.

I just recently went thru all this and came from the same turbo 4cyl background. Welcome to the forum.

Cold air for power, hot air for mpg, cold fuel period... Tune in cold weather. Dial it in as temps heat up... I did this recently and results are awesome for what i use my truck for... Daily driving... Just now attempting to get it fine tuned with smoke table

BBi 0.5s
Borg Warner 363sxe
Aftermarket manifold(either third gen or second gen style depending on depth of pockets)
Built trans
MM3 with tunes by Gordon (dodge74 on here) or someone else on here
Single piece driveshaft
Added fuel filtration
Steering box brace
Bypass heat exchanger
Install dynamic transmission thermostat bypass in front cooler

That's a solid build right there. Should be good for many many carefree miles.
