s466, 67, 67.7, 71, 72 or drop in atmo turbo

[stroker221]

Looking for any of these s400 based turbos or a drop in atmosphere turbo 72 or larger for my 6.4

I'm still kind of on the line which way is like to go so just looking to see if theres anything used that may persuade me which direction to go.

Also interested in a complete single kit.

Thanks
