I'd like to get some feedback on these motors because the new WRX and Forrester XT are full of problems. My take on Subaru is that when Toyota came in, they saw Subaru as a company that utilized DECADES old engines, which was fine because they worked, but I have a feeling Toyota gave Subaru a strict time frame to release all new motors that were significantly economical.
I have searched and searched about the FB motor found in the naturally aspirated motors and they seem to be holding up just fine. The BRZ/FRZ FA20 initially had problems with ECU programming, which is reminiscent of the 2015 WRX ECU issues. I also have seen the nightmare of servicing the Toyota D4S GDI system in the BRZ/FRS, which makes me question the longevity of the BRZ/FRS. Lastly, I find it a bit odd that the new Boxer engines use 0w20 from the factory. When I has my old Impreza I would put Rotella 5w40 during the summer because it would vaporize 5w30 oil.
