Message The fit was "okay". But didn't have an option for a heat shield which meant we needed to wrap them. Again, reluctantly I wrapped them as well.

Mounted a stock T25 turbo onto them. Again, fit "okay". But when I was installing I kept thinking that the metal was just so flimsy for carrying the weight of the turbo, down pipe, oil and water lines, intake piping. All the items attached add for a lot of weight to hang on a manifold. I gave them 6 months.

I was wrong.

They lasted 4 months. The owner daily drove the TT and just kept driving it with a cracked manifold. He ended up selling it to someone out of Austin. So somewhere in Austin is a leaking manifold that is in a car that was sold to someone that hopefully replaces them with a quality piece.

Personally the weight of all the turbo assembly is too much for most of your metals. Guys have tried iconel and a few other dense steels with little luck. A solid cast manifold is really the best option in my opininon.

Now....what you choose in THAT department is your choice. But understand that there are a lot of good Z enthusiasts on here with a lot of mechanic experience under their belts. So if they take the time to answer your question, it's probably in your best interest to listen.
