To be clear: These are not the same design as Garrett. They simply copied the naming system for their similarly sized turbos. They do not include Mar-M turbine wheels with the efficiency of the Garrett units, and the compressor wheels who knows? It's the classic Chinese knockoff.

If you think "overboosting" changes a turbos balance, you probably should step out of the conversation for a while. Also, twisted motion is hot garbage.

The problem with bad turbos is when they die, they usually send shit through your oiling system, which is bad for oil pump and bearing life. It's not as simple as "get a new one when this one dies".

The ability to fit a relatively straight, 4" intake pipe in front of the turbo. The rest is the same.
