Have any of you on the forum made performance enhancements to the engine of your Legacy (2.5L)? If so, what did you do and what were your impressions of the modifications you made?
Are "performance chips" or "performance programmers" of any validity in increasing performance of this engine?
So i have my ej25 in my 99 legacy with only 6000 miles on it (previous owner got it replaced at almost 200k) and i want to put a turbo on it in the future, what could i begin to do to prepare it to be turbo ready? /should/ i even try to put a turbo on my subaru? I have a beginner to moderate...
