i was wondering if it is possible to put injectors out of a newer 7.3 (99-03) in a obs 7.3 (97). i know old body 7.3's have 90cc injectors and newer 7.3's have 120cc injectors. just wantin to know if it is possible and if it would be a good "performance" upgrade. also where is a good place to find ladder bars. i need them bad.

It is a good upgrade, but you will need to get split-shot programing for your OBS to make it run right. You should look in to a DIY injector kit and do your own 160cc single shot injectors.

Yeah switching those injectors over is a lot more work, i would go the DIY route as well I pulled my stock injectors out and sent them to DIY injectors to be rebuilt and they are now on their way back to me it was only 475 bucks

you would also need to get a bigger hpop to run the split shot injectors to get all the good out of them because they use alot more oil. the 99.5 and up trucks have a 17degree pump and we have a 15degree.

wow they r a great price. im probablly gunna get the stage 1's. i dont have to do anything to my fuel system to be able to run these stage 1's do i? the only reason im asking is they say they are up to a 110 hp inceasre? so will my stock fuel system be able to handle pumping that much fuel?

With Stage 1s your stock fuel system will be fine
