I'm a bit confused, do you want to take a kit for a 4.7 ram and put it on a 5.7 hemi ram? Or is it that you want to take the kit from the 4.7 and use it on your truck?

The STS kit for a 5.7 hemi, can i use that on my friend's 4.7 ram? Like is the piping pretty much the same? Are there any tuning software for the 4.7?

I'm not sure how the 2 trucks are laid out, but I would imagine it wouldn't be too hard to make the kit fit physically, and if it has the t-60 turbo, you would probable want to put a smaller .68 A/R exhaust housing on the turbo. The biggest problem I can think of is the tuning. You need some way to add fuel for it. I'm not "up" on Dodge tuning, and I don't know what is available for them.

The piping should work but you need a smaller (maybe GT35) turbo and smaller injectors than the ones used in the 5.7L Hemi. You can get more info at DTW or PM me.

The GT35 would be a perfect turbo for the 4.7 IMO. The physical pipe layout will basically be the same. Just gotta get the right injector setup. Something a TAD larger than the 6.1L hemi injector probably.
