I am considering doing a STS universal turbo kit to my 99 f350 5.4l. I have looked all over the internet and have not found anybody that has done one. I have seen superchargers and prochargers, but I want to be different and consider this turbo kit. I know I could do a diesel swap but I am trying to be different here and keep the drive-ability of my truck. I want to keep boost to about 5-6 psi and need to know if larger injectors will be needed. My friend is familiar with turbos on tuners, but not as large as this truck so I also need to know what size turbo I should be looking at. I do not think that the boost will hurt my engine since guys put superchargers on them quite often. Let me know what ya'll think.

 

Sure to be an interesting build, this link should set you in the right direction for sizing...

perhaps you shoulddrop mike at 5 startunning an email he's walked this path he'l be more then able to give you do's and don'ts

- my advice to you is keep it simple and upgradeable as possible should you thrive for more POWER!!!

-for 6 psi you'll need a new maf (gen2 lightning will do and are pretty cheap)i got a gen1 and pegs at 4psi on a blow threw setup.

-iinjectors will be a must, you can get an fmu from vortech which would make your stock injectors work, but beworned no tunner liks a fuel management unit, on that note.
My advice 39lb+ with an inline fuel pump, and for when you want more hp you'll just need to get an fpr boost refrenced of course.
