Not trying to be a dick, but please (pretty please) answer just my specific question because I am old, I don't understand all these numbers, and I want to start shopping.
What is the biggest, most horsepower, turbo, gas, Subaru engine that easily ( no drive by wire or anti theft stuff) can be swapped into the car? |

The WRX motor 2006+ is even the same displacement as the STI motor but cheaper. The EJ207 I suggested above is just the JDM version of the STI. Both motors great for power. My suggestion on adding forged Pistons is only if you wanted a big turbo and big power. It's not 100% necessary, but at big turbo/high boost the EJ motors have a known issue with ring land failure. My daily driver is an 06wrx and I have been running 15-17 PSI on the engine for its whole life (now at 117,000) |

Also, is a twin scroll turbo an option for fitment? |
