Really. That surprises me, but that's why I asked first. Are you saying that because the ATS looks like it's been used harder? I'm a newbie at diesel's but I've always been a hot rodder so I'll wind up trying to make more power eventually. For now it would be going on my stock 130K mile 7.3 for better fuel economy mainly.

I have a spare 7.3 in a parts truck that will get a rebuild and maybe some performance upgrades like J2 cam, head studs, etc. The turbo would wind up on that motor so a wastegate might be necessary.

I figured the age of the banks kit would make it harder to get parts and that the ATS would be better due to a more modern design. I also read that mounting the old style Banks air box is a pain. What are the pros and cons of each kit?

 

i prefer the non wastegated banks unit.
i regularly see 15 + lbs boost pulling loads with open exhaust.
if i remember correctly the most you can get out of a wastegated ATS unit is around 12 lbs boost

and i "slightly modified" my air box.

 

It looks like either way your going to add parts. Call Banks and see what they have. If you can make them that's better. If the Turbo on the other ATS is toast that's pricey as well.
