Ive been trying to find the perfect injectors. I've decided to just build up the 6.0. I'm trying to get a "grocery list" list together. Im tying to figure out what the biggest injectors I can run without modding the fuel system. Also I saw on a previous post that if I go above 155's I need to swap out the turbo $$ I don't pull a lot as of now but in a few years I plan on getting nice gooseneck camper. Is there a website that anyone knows of that has some kind of chart I can look at and study?

 

Not sure if theres a chart for injector to turbo sizing and fuel supply. Ive read 155s and 175s on stock fuel system. Not sure if id do 175s with out doing aftermarket pump. Also id just plan on doing fuel system and turbo for anything over 175s, and plan your build for what you may tow in the future so you don't shoot yourself in the foot down the road.

 

I can drain my fuel pressure on my stock injectors... so going larger isn't going to help. Put a fuel pressure gauge on, without it you're pissing in the wind. You'll have no idea what you need until you can see what you've got now.

155's and a stock turbo is fine. You may also want to check out the MTW turbos, cheaper than a whole new unit and match these smaller injectors perfectly (stage 1 and the hybrid turbos).

However, what's the point of adding a bunch more fuel (larger injectors) if you don't upgrade the air side to burn all that fuel? You can put whatever injector size you want in, the tuner is just going to pull fuel out of them if you don't have air to match it.

For 155's or 175's, I'd do at LEAST an airdog150 or some other similar pusher pump feeding the stock pump, and a regulated return wouldn't hurt either. A sump would also be on this list and most importantly the fuel pressure gauge...
