So far I am very impressed with the motor holding up in these multiple turbo kits. There have been tons of Dyno runs, 1/4 passes and track laps. Some of these cars are making well over 400HP.
For me that means my dream of a rather low boost kit with 300WHP would be a very reliable car.
If that fails then I will swap one of the new FA20 Turbo motors from the new WRX when they become available.
