I've never seen a Chinese turbo last longer than a month, they are made of cheese, so fit Garrett internals as well as externals and it might be OK.

You'll have to be very conservative with boost and ignition on 95 juice and no knock control. I'd be surprised to see a GENUINE 250.

It would drive better with a smaller TB, no bigger than 50mm.
