Hi all

Has anyone had any experience with these turbos

Thanks in advance.

A Chinese one.

I'm in need of a marine turbo, I can get a Chinese one from ebay for £500 or go to the main agent for £2500.

I know a bit about turbo design and manufacture as I spent some time project managing turbomachinery development.

You have to ask yourself, is this a fake, wrong materials, wrong processes, made from fake reverse engineered tooling, with no control, or at least inadequate control, of the processes in the factory that made it? Or is this a part that has found its way out of the back door OEM production line? Could be stolen? Could be a quality reject?
