Lately, I have noticed a lot of WRX and STi turbo sizing and pairing questions poping up in this forum. This is not the place to post those questions, as this forum has one purpouse only, and that purpouse is information regarding Turbo'ing a EJ25, or even a EJ22. Please post your WRX questions in the apropriate forum, links to which are below.

-WRX Powerplant Here you can ask all the turbo questions, intercooler questions, and general questions about the WRX powerplant (EJ20)

-STi Powerplant Here, you can ask all the turbo questions, intercooler questions and general questions about the STi powerplant (EJ257)

-Non-Turbo Powerplant And finally, if you are not looking to turbo at all and want to find ways to make N/A power, go here and ask your questions, and someone will be sure to answer!
Cheers
