Injector Recommendations

[dmashuda]

Hey guys, just wondering what are the biggest injectors i can run on the stock fuel pump, hpop, ect. The only thing done to the truck is bulletproofing it, k&n intake, 5" exhaust, stage 2 vgt turbo, and sct with idp tunes. I need to know what would be a good option for the truck, size and brand, and i want to be able to pull it in the stock class at truck pulls. I can change injectors but not pumps, so anyone have any suggestions with this setup?

I haven't ran 6.0 injectors besides stock. I'm going to say don't run a bigger injector tell you have a bigger fuel pump. With a fuel pump I would say 190s with 100 nozzles?, on stock
hpop.

Jeez read your post to quickly, not to sure on the pulling part sorry. Maybe a good custom tune would help you keep up your fp with bigger injectors.

I bought my Cass 155's from them and they ran fine on stock fuel pump.

I was able to run Elite's 185s with the stock fuel pump and a regulated return for a while. never had fuel pressure issues. You just need to make sure you are usig good fuel and shanging fuel filters regularly.

Your stock HPOP should be good for 205s , maybe 225s if you have a strong one, but the fuel pump probably won't handle that.

My stock fuel pump after 100k miles wouldnt hold pressure with stock injectors on a good race tune.. all depends on the health of the pump IMO...

Exactly!!! A healthy OEM pump can support some moderately sized injectors. Clean fuel and fresh filters will hopefully keep it healthy

Ahh true, never thought of that. I'll have to make sure thats up to snuff before i do anything else. Filters get changed all the time so it should be getting good clean fuel, but with 140k on it, its possible that the pump is getting weak.
