So u didn't change the exhaust, downside, or cold side at all, cause i don't think u shoulda had any real issues with urn.previous outside, also did u measure urn backpressure now.with the bigger housing?

Nope didn't change anything else and backpressure is now right around 1:1 which is what I was told it needed to be. As I said it made 865 on only 14 psi of boost so its obviously pretty healthy. I understand others have gotten away with the 1.08 housing but who knows what their combo was, maybe they run stock 317 heads or don't have the right cam profile for a turbo setup. I do know this has worked for me.

haha thanks this is my first project with my new tig welder and they seem to be coming out pretty decent i guess, but it is definately mentaly draining trying to make perfect cuts and getting the angles right while still clearing everything
