Hi guys just wanted to bring this to everyones attention.. seems like a competitor is selling fake T4 Turbines, claiming they flow the same as our REAL T4 turbines (.84,1.0,1.06 etc...) We have one of those turbines here are at the shop and we put it next to one of our T4 Turbines and if you look closely you will notice a clear difference in volume and size between the 2. It seems like the competitors "T4" turbine is most likely a Modified T3 Turbine with a T4 flange on it. Obviously the true T4 will flow more than the T3 turbine with a T4 Flange. Look at the pics closly especially near the middle and you will clearly see the difference as the left turbine is wide throughout the turbine and the competitors is very narrow (fake). These turbines are "supposedly" the same A/R's. obviously, your performance will suffer!
