175cc injectors? Stock nozzle,30,50?

Im trying to see what the differences are between a 175cc injector with stock nozzle and aftermarket nozzles? Ill be pulling my injectors soon to be gone through and want to see what the advantages are between stock and aftermarket nozzzles? Going to still be on the stock turbo with possible a billet wheel and powermaxx or stg1 later down the road.
Thanks for your help.


Jimmy

The larger nozzles is where the power is gonna come in. Quicker fuel delivery. You can get any size nozzle in a 175 and be ok as long as you have good tuning.

155/30's has proven to be a great injector for towing. Look up jetjock and his set up. He tows all the time with his truck and that is what he is using.

155/30 is a great option for towing! Especially if you r planning on staying with the stage 1 or pmax.


175/stock also does pretty well. Once you put nozzles on 175s it can get hot and Smokey

I currently run Erics extreme street tune. After the studs and gaskets go in Ill switch to the extreme race tune. Guess Ill have to get him to modify the tune for the bigger injectors. Now to pick what ones to go with.

In hindsight I should have went with 30's but my nozzles are different than most they were extrude honed to open them up back before people were offering nozzles for 6.0's when I had Jesse warren turn them into 175's his best estimate was to call them 50's. I have to be very carefully towing. They flow a lot of fuel I can see a significant fuel pressure drop with a full fuel tune even with my regulated return.

I had 75% and now have 30% nozzles.. It is better towing but still not perfect.

Jesse warren steered me towards 175/30's and I couldn't be happier. Inhavemt tkwed much since then because my trans went out shortly after...not really the injectors fault...a litany of factors. Call Jesse up and see what he says, I trust his judgement pretty much 100%, this is his livelyhood...but more importantly as many as he's built he's probably seen every combo out there and knows what works well together.

From my injectors and reading other peoples results, and talking with Jesse...I'd say 30% nozzles are a good fit. You can still pull enough fuel out of the tune for towing without sacrificing atomization and all. If you towed either really often or a whole lot of weight is stick with 155's...but again just call Jesse and see what he says.

Also part of my decision to buy nozzles wasn't just performance related...I've seen a few core engines come in with injector nozzles that had evidently eroded or somehow melted the tip off...bad fuel or debris evidently can hurt the nozzles and cause issues, so I decided new nozzles were worth it for that and the performance aspect.
