    Stock Turbo trouble

    I bought a 2004 impreza wrx 2.0T about two weeks ago. I over looked the boost gauge when i was purchasing it because everything under the hood looked exceptional. As I started driving I noticed the boost only got to 9, stock on my model is 13. I cannot figure out why its not hitting that. Any suggestions

    What units are you talking about? 9 what? What units does the boost gauge say it's measuring (the units will be printed on the face of the gauge).

    Assuming you're talking about psi, your WRX won't make full boost until 3rd and 4th gear.

    Some advice too, find the OEM recirc valve and get rid of the BOV. It's just a noise maker and can cause your car to run rich.

    Getting rid of the BOV was one option, I know it causes me to loose power but I didnt blame it for not hitting 13 psi. I have had the peddle to the floor and have not seen 13psi. Im starting to think there may be damage somewhere? or possibly need to replace the factory turbo?

    Agreed. I'd consider the BOV first. The OEM is the best choice.

    That is not in PSI. (In fact, it shouldn't be... this is IMO but non-SI units need to meet their end ASAP -- but that's another story).

    Anyway: There is nothing in your posts that has indicated something wrong with your boost pressure. The stock gauge is in Pa. For info on the Pa (it's 1 N per square m).

    The BOV is kitsch but it is not affecting your boost max. In fact, I doubt anything is.

    Check all of the IC hoses and be sure there are no leaks as well. My OEM BOV performs well at 20 psi of boost.

    Stock Boost Gauge

    So .9 MPa pressure is equivalent to... the car seems fine.

    Not to the car unless you somehow generate a leak when swapping the gauges. A little piece of my soul will be hurt though, as you'll be regressing to a non-standard unit...

    EDIT: In fact, I could swear the company, Omori, made gauges that match the OEM dash and fit in the OEM gauge "cup." They were coin and I don't know what vendors might still carry them. They did match very well though - or, for much less money, other gauge brands are widely available. Check out the club's vendors if you like.
