7.3 Powerstroke Stage 2 Performance Injectors 180cc 1999-2003
So what makes an injector a Stage 2?
A stage 2 performance injector has the same internal modifications as the stage 1 and stage 1.5 injector internally. The main modification for both injectors is inside the injector on the intensifier piston. This piston is a mechanical limiter, it's modified or shortened which allows the plunger stroke to move slightly farther so more fuel is pushed through the nozzle during each injection cycle. Each injector is also converted over from split shot to the more efficient and powerful single shot design. The split shot system includes a wasted pilot injection originally designed to make the engine quieter during idle.
Here's what make the stage 2 a higher horsepower injector over the stage 1 and 1.5. The nozzle size is larger. These injectors have a nozzle size of your choosing from 80 percent larger than stock to 100 percent larger than stock. The larger nozzle moves the total available fuel (180cc) quicker into the cylinder for a larger (more powerful) explosion. The quicker the fuel empties from the injector into the cylinder the larger more precise the explosion and more power is achieved. So understanding this you can choose the larger more powerful 100 or the smaller 80 percent nozzle to reduce smoke and EGT levels slightly.
Advantages and Benefits of the Stage 2
The stage 2 makes more power but keeps the total CC volume lower over their hybrid cousins. You can make performance oriented power with a same stage 1 total flow rate of 180cc. More power with decent fuel economy is a win-win right? Sort of...
With the larger nozzle come more smoke. Although you empty the injector quickly you also provide the truck with a little too much fuel to burn completely in a stock truck. The by product is excess black smoke and higher exhaust gas temperature from that unburned fuel. The majority of this smoke comes on the low end of the throttle when the turbo hasn't built enough pressure to utilize the fuel. Most refer to this condition as lugging the engine. This isn't harmful to the engine or turbo but that's when you get the cloud of smoke when you're taking off.
The good news more of that fuel can be burned or cleaned up with a few more upgrades like an air intake, larger turbo or bigger intercooler. Another option to keep the smoke and EGT's down even without a turbo modification is to purchase the Low Smoke Custom tuning from the drop down menu on this page. These tunes are specifically written to make the max power available but only inject as much fuel as the truck can use. The fuel injection is matched with the turbo boost production giving a very effective balance between power and a clean exhaust. Very street friendly tunes for the injectors and also custom programmed for any other truck modifications you may have.
Stage 2 Injectors Summary
- Great balance between a towing injector and performance injector
- Choice of nozzle size to fine tune your needs
- Fuel economy doesn't suffer (depends of course on your right foot)
- A custom tuned chip is necessary to run these injectors because we convert them to single shot - free chip reburns available or purchase a new chip above with the desired tunes from the drop down menu
- Extra modifications for air not necessary but advised
Warranty: Full Force Diesel Injectors include a 18 Month Unlimited Mileage Warranty!
180cc vs 160cc:180cc is the best choice for most 1999-2003 trucks. The only time we recommend the 160cc injectors is in high altitude locations or for the customer that don't want a large power increase. The only benefit of the 160cc is the 99-03 is converting to a more efficient single shot injector with a very small bump in power. The stock injectors have an effective flow rate of 120cc.
We do not charge any other fees to repair your core injectors. Please note some of the other companies charge for bad parts on top of the advertised price and do not use new plungers and barrels or nozzles in their injectors. Injectors that have ran vegetable oil leave a damaging coating and will not be accepted as cores. New nozzles, plunger and barrels, and other new internals in every Full Force Diesel injector. Flow matched and ready to install when you receive them.
Tuning Information: New Full Force Low Smoke Tuning. We now offer low smoke *Clean tuning. In a time when clean tuning is more desired we've step up to the plate. The days of "Clouds of Black Smoke" are behind us. We have partnered with a very reputable tuning company for the lowest/minimal smoke with modified injectors while maintaining optimal power output. Normal driving will yield very low smoke levels and very good power. Foot to the floor will make moderate smoke on the highest setting. Results of this custom tuning typically results in very good smoke control but smoke may vary. Tunes included are hi-idle, heavy tow, tow, street, hot street, and extreme. During the order process please indicate any further tune request you may need. HPOP, Transmission, etc. They will be custom written for each truck.
Frequently Asked Questions:
Custom tuned chip: If you don't have a tuner or a chip currently please select a TS chip or Hydra chip. This has to be done to convert the computer to a single shot fuel injector program. All tunes still add the appropriate power. Tunes included (*for most trucks) Heavy Tow, Hi idle, Light tow, Daily Race and Extreme tunes. Low smoke tunes are tuned custom by our tuner to get the most power with the least amount of black smoke.
Core charge:Every injector set requires a core charge. Please select add core to send your injectors now and refund the money later. Best way to not have down time with your truck. Or sending in first for us to wait and sent your order when we get yours to avoid paying the charge. Sending in first shipping label is we email you a label to get your cores here. (Saves you time and hassle)
Reburn my chip for free: If you have a TS or hydra we'll put our tunes for the injectors on your chip. Leave the add a chip to no thanks. Then select "free reflash" meaning you send us your chip (TS or Hydra) and we reprogram and send it back to you. Hydra email tunes is just that we encrypt the tunes and email them to you to self install. Email tunes Hydra Low Smoke is the custom tuning for minimal smoke also emailed to you.
