You simply cannot plan your WRX build the same way you could up through model years 2014 for the WRX and 2021 for the STI. The car is fundamentally different than previous generations. The FA20DIT powered WRX is a massive overhaul from what Subaru owners and enthusiasts were used to prior to it's 2015 model year release.

A catch can is a device installed between the engine's crankcase and the intake system. It “catches” all the oil vapor that passes from the crankcase back into the intake system where the crankcase vents. This oil vapor has a low octane rating and also coats the walls of the entire intake tract and builds up over time. When the junk from the crankcase makes it's way into the cylinders, it can cause detonation and reduce the performance of the engine.Read More
