Hey there, my name is Jesse and I just purchased an 02 WRX wagon. It's completely stock except for a K&N filter and iridium plugs I just put in.
1) I live in Salt Lake City at 4300 feet. The most boost I've been able to achieve is .075 MPa or 10.9 psi. I know part of this could be due to elevation but it still seems low to me. I would think 13psi would be more reasonable. So I'm wondering if I should get an MBC and up it to 14 psi or look for issues with the turbo/vacuum leaks, etc?
2) Any typical problem spots for oil leaks on these cars? I noticed I'm down about a quart after 2500 miles. It's probably not a big deal as it's a slow leak but still wondering what it might be.
