Use this forum for posting threads specific to the STi 2.5 L engine.
Threads that are not unique to the STi should be posted in the Engine Performance forum.
Let's strive to keep this forum organized. If there is already a thread about a particular topic, add to in instead of starting a new thread. Also, please describe your post accurately in the subject line, so that it is easy to identify the topic.
And, as alway, please search before starting a new thread. There are many topics that have been discussed over and over. Also keep in mind that there is valuable information on the standard WRX Engine Performance forum.
Thanks for your help!
