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) |

QUOTE(matthepcat @ Jan 12 2016, 08:08 AM)  It's not 100% necessary, but at big turbo/high boost the EJ motors have a known issue with ring land failure. Important to note, that's ring land failure of the STOCK pistons when run with huge boost from bigger than stock turbo. It's no different than any other engine, increase the power a lot and you need to make things stronger so stuff doesn't break. You can increase the power/boost considerably from stock, as Matt and my son (when I'm not looking) have done, but stupid big increases will eventually cause problems unless you upgrade the stock internals. And that's the basic difference between the STi and WRX motors, upgraded internals, bigger turbo and injectors so it can run higher boost for more power. |
