Its not a garret T3/T4 turbo thats fur sure... its a copy. I wouldnt trust the intercooler either. Impeller blades are most likely ceramic, cooler properties are prolly crap and have massive pressure drop across the center. Turbo timers are a gimic really as a who would drive their car on full boost for ages unless at a track? Normal driving/spirited driving you wont need one.

At the end of the day you get what you pay for. But i wouldnt spend that little on a turbo setup. Last thing iw ould want is part of an impeller go through the cylinder and maybe bend a valve or crack a piston or something.

Not worth the risk in my opinion
