Im wanting to try some injectors in my e-99 and need a little direction. With the mods in my sig. and a 17* hpop on the way, i was wanting a little more power and i for sure want single shots. I have read of windowing blocks with around 400 hp and i was wondering if there is any need for concern with stage II's in my aplication? I do everything from light to heavy towing to cruising up the interstate empty. I know the DP tuner is a requirement with single shots as well. But i don't want to spend the money on stage I's and be disappionted either. What do you guys suggest? thanks

 

I've been completely convinced that hybrids is the way to go. With your 99 block, you have the forged rods, so going over 400 hp should be just fine. It's the PMR's that get a little dicey at those power levels.

Hybrids make good power, more than Stage II's. At the same time, you can dial the power back to just about bone stock (even the smoke can disappear completely with the right setup). So hybrids have great tune-ability. Plus they are more "oil-friendly" with a 17* HPOP. They still benefit from big oil, but do great with a single 17 degree too.

Now it's a matter of where to get your hybrids. You can go with Swamps, Casserly, Diesel Innovations, or Rosewood to name a few of the most recommended dealers.

If I were you, I'd go with a 38R too and dump the stock turbo. Since you've already done the late model turbo swap, the 38R is a direct bolt on.

 

Good thread, i,m almost convinced going with hybrids is the best choice for me considering my PMR's, been taking to different people and all been saying the same thing...

 

I'm leaning towards hybrids also myself if I ever have the $$$, though a lot of guys are running AC injectors (OEM stage 2 singles) and are happy with them.

 

Thanks for the info guys. Also what will my boost levels be with bigger injectors? I just installed the late model turbo and hate to scatter it right away?

 

my vote is for hybrids also! Curtis made some very good points

 

Oh the injectors/turbo debate!!! CJ, you're going to get 30 different options from 30 different people.

So here's mine...

You've got to decide what will work best for you. My dad's 95 (used to be mine) has stage 1's with the stock smaller plunems and turbo, stock 15* pump, running a TS style 4 pos. chip. It's never been dynoed but I'd estimate 375ish hp. It's pulled heavy loads up and down the roads over the years as well as ran empty a bunch. It'll still roast the tires if you want it to. And it gets good fuel economy when just cruisin. Its currently got 276K on it and this setup has been on it for almost 150K miles now. When I upgrade to the h2e on my 02, it's getting the late 99 upgrade that is my setup now along with a 17* pump. Honestly I wouldn't have anything else in that truck cause it does anything and everything I/he wants it to do, gets good mpg and is strong.

I just put stage 2's in my 2002 with a van turbo (same as yours only with a non-wastegated 1.15 exhaust housing) and am clearly running out of air. I've got much more fuel there than the turbo can handle, so it's going to be upgrade time in the future. Maxed out with a modded h2e, big oil, and these 2's I'll be 500rwhp or just a hair more. BUT - it's going to take several more thousands of dollars to get there!

So...

My suggestion is stage 1's and keep the turbo you just put on. If you go to hybrids or 2's, then you'll be upgrading turbos also. More power, but costs a ton more to get there. If you want good mileage, good reliable power, great towing power, without selling both your kidneys, then get some stage 1 single shots. Have TW, DP, Cale, Swamps, DI, PHP, or whoever else is out there set you a chip up for them and go. WAY CHEAPER and extremely reliable for what you've got so far.

When I get my stuff switched over to the 95, I'm going to have the 5+ year old chip reburned/updated and it will run even better than it does now.

 

With the 1.0 exh housing, you might be okay with stage 2 sticks, but the 1.15 van turbo housing would've been a bit better option. 1.0 is good with stock or slightly modified sticks, the 1.15 van turbo or 38r is better with the bigger injectors. Like Curtis said, you have a forged engine, so big enough injectors to fully light up a 38r is possible for you if you want to spend the $$$. Just be aware that some forged blocks have let go in the low-mid 400s. Forged doesn't always = safe at 500 HP. You have to stay on top of the tuning like Mike (Tenn) has. He's running right at 400 on a 38r & hybrids with a PMR motor & diode trans.

 

Great info guys thanks a bunch! I really would like to know if my stock turbo can handle the stage II's? And if the is any hp difference in a StageII with 80% noozles or 100% noozles. My pick-up runs well but just want to have a hard pulling but safe set-up for pulling moderate to heavy loads!

 

HP doesn't kill engines, a stupid foot does along with poor tuning. Get some hybrids with good tunes and you can support up to 500hp as long as you have the air to get there. Read, not van turbo It will never get there and the 38R will be at it's limit if it gets there with x combo too..

 

Hybrids... Dont waste your money on anything else... Hybrids and GOOD tuning...

 

When ever I get the money saved up some 200/30 Hybrids from Swamps or Casserly with a van turbo until I can find a great deal on a 38R or H2E. Along with some live tuning.

 

How much performance difference is there between the stage I and stageII's? i can't afford the hybrid nor will i ever get the full potential out of them so i would like to stick with the single shots!

 

Hybrids are single shots. They use B code injector plunger and barrels so they can squirt more fuel with less oil.

 

If you're staying with the turbo you have, SS injectors will work fine. I don't pay attention to "Stage" whatever. I just look at the flow rates for the injectors. "Stage II" SS will work okay I think, but you will be pushing that turbo pretty hard. You can always have them tuned lighter if you don't want to go with a bigger turbo later if the "Stage IIs" end up pushing it too hard.

As you're seeing, there are a lot of choices out there for injector/turbo combinations. I know the Swamps 175/146 SS (I think those numbers are right!) work with the van turbo, and SHOULD work with the 1.0 housing. What "Stage" those are, I don't know. I do know they result in about 360 RWHP on the dyno.
