Injector Options

Dirt devil · Feb 8, 2015

I have tried searching for more info on injectors but didn't find what I am looking for. My HPOP just took a dump and now I should have the injectors inspected/freshened up. However I am thinking that if I am going to spend any amount of money maybe now is a good time to upgrade.

So my question is what would be the largest injector I could get away with without having to install major mods (head studs, big turbo's, etc). The only thing that I will be upgrading from my current setup is a 38R BB turbo. The truck is my daily driver and tow rig.

Thanks Dave

That's a tricky question, as you don't have to upgrade anything to run big injectors, other than tuning.

If your question is "What's the biggest injector I can run without needing major modifications like head studs, big turbos, etc, to optimize those injectors?"
Then I'd say with your 38R, add an Adrenaline HPOP and go with Stage-2 AD's. You will be set-up well to run them perfectly and it will really wake the truck up overall.

You can run any sized injectors you want. Just depends on how brave you are and how good your tuner is.

It would be good to know what your power goal is, and how you plan to use the truck. Then you'll get better recommendations. Otherwise you're going to get 50 different answers. There's different injector sizes in overall CC's, then there's various nozzle sizes. And on top of that there's different injector builds (A codes, Hybrids, B codes). Put that all together and you have a ton of combinations to choose from, all with different characteristics, applications, tuning, oil requirements, performance, smoke, EGT's, yadda yadda yadda....... within various RPM and engine load ranges.

Jim your correct that's what I ment to say W/O needing the extra mods.

Valid point Curtis

Honestly I'm not sure on a hp# I'm not out to win any race just want a great running truck that is a DD and tow on occasion. But I don't want to worry about having to buy more supporting mods as I'm where I want to be other then a new HPOP and In the future a 38BB.

From what I've read thus far PIS 160/30 or 175/80 looks like a good choice.

bruce · Feb 9, 2015

You have some nice mods. 175/80 would be nice or a set of small hybrids

I love my 38r 175/80 combo. Fun daily driver and tows extremely well.

Tim @ P.I.S. · Feb 9, 2015

Since you have an upgraded hpop I would go with the 175/80's. It's really a great do everything injector and is matched perfect sight the 38R turbo. We have done that combo countless times. And with the right tuning every last person has been happy.

mandkole · Feb 9, 2015

175/80 would be fine if turned down to keep the clutch happy for awhile. That Luk was fine at 300-330 and those injectors will be at an honest 390-400. The question is, how much do you want to keep working on it? Can you afford it to be down after a mishap from 'runnin thru the gears'? Injector upgrades will tear up parts up as you enjoy this new found powah...

Just what you need Dave.

Ok so now who's tunes do you recommend and can they be used with my current hydra chip?

Dirt devil · Feb 9, 2015

OK something else that I am considering is Swamps 175/146 injectors. The reason being they offer free tunes with the injector purchase (I can use my hydra) and they don't charge up front core charges which is a plus as I need to order a HPOP as well.

Anyone that has them what do you think of them?

I'm currently running them in my PMR motor and I've been very happy with them with their tunes, so I can't speak for how they would do with anyone else's tuning. Truck is DD an average of 50 miles/day and tows 26' toy hauler loaded with 3 4wheelers (or 20' bumper pull loaded with SxS and 4wheelers) about once a month, 26' boat on occasion, misc loads for landscaping or house projects, you get the idea. I've run some of their smaller sets and currently have their larger sticks in my other trucks. No complaints with any of the sets I've had and they've been great about tuning changes when I've wanted them. You can PM me if you are looking for specific feedback or have a question.

Who needs tunes. IM running PIS 300/200 on a stock pcm. But my truck is a single shot truck. But honestly these injectors a smooth.There are a bunch of tuners out there that will tune your truck for cheap. All in all there would be a deference of like 200 bucks. Heck call PIS and ask if he works with a certain tuner. Never hurts to try. Swamps have great products also, I just know myself and some others that have ran 3 or 4 brands Like PIS. Call him up and ask him about failures and what's covered etc great people over there

I'm more of the mindset who doesn't need tunes?

There is a difference between cheap tunes and good tunes. Not saying they're mutually exclusive, but not all 'tuners' are created equal. Some people have never met good tuning and just don't know any better (not saying this towards you). :shrug: Then there are others that just have a warped sense of how they want their truck to behave. Friend of mine does his own tuning, I can't stand how touchy his pedal is and his shift points, it's all wrong for me. Just have to find what works for you.

pullandpray · Feb 9, 2015

Oh I have ran tuning and I have to run running when I pull my big 5er just having issues with my current tuning and cold weather. Been wanting to get some live tuning from jody but living in the sticks is a real pain

Funny, injector brands are the exact same way. People still have the mentality that just because the #'s are the same it all works the same.

You don't have any custom tuning and you run twin HPOPs?

pullandpray · Feb 9, 2015

Yup, no custom tuning as of right now. Like I said I can't tow with it I know that. The truck actually idles and drives and behaves pretty decently. My current tunes on my ts chip do not like anything under about 20 degrees my truck will start bucking and ever thing else. Fuel deserved is very high with that tuner and mileage sucks compared to just the stock pcm so that's what I'm running currently
