150 nozzles are horriable on the street, it's not worth doing if your keeping a stock size injector. You only need something that big when your push over 250cc

Don't mess with the nozzles, just send your injectors to warren and have them gone through and rebuilt to a 155 or 175 for an affordable performance upgrade.

Ok so I dont tow super heavy things. I do haul a car trailer and the most it would have on it is maybe a truck the size of mine.
So which do you think I should go for 155s or 175s? and if I do go with one of these sould you suggest maybe smaller nozzles or still stick with stock nozzles??

Stock is 135cc

most people go with 155cc or 175cc with stock nozzles as a small upgrade. Adding nozzles doubles the price of the injector.


135, 155, and 175 is the amount of fuel the body of the injector can hold

stock nozzle vs 30%, vs 75% vs 150% etc... this changes how fast the injector can dump the fuel.



Essentially sticking a larger nozzle on a stock injector will just make the same 135cc dump faster with lower atomization. This will result in a hotter smokier truck, not really more power. The hot tunes out there have enough pulse width to dump all the fuel in a stock injector so there is really no need for larger nozzles on a stock injector. The reason to get a larger nozzle is after a certain amount of cc (like 175+) the stock nozzle cannot dump the fuel fast enough at the higher rpms. So you get bigger nozzles to dump the fuel faster to use all that fuel your larger than stock injector holds.

155/stock and 175/stock are good upgrades and very popular right now.

Let me know if you have any more questions
