    New WRX Owner - 03 Sonic Yellow - and a Turbo Question

    Hellooo everybody!
    I just drove up from Atlanta to Maine with my new WRX and I love it. I go through cars pretty fast, as I usually just buy a used one and then sell it for a little bit more. I've done 4 this last year, but now that I finally found a good deal on a WRX I plan on keeping it for a while. They're my favorite - I'm only 21 and already have my dream car for $6400. From Georgia, no rust, almost all stock. She's a sonic yellow one, and while I was a little hesitant about the color, they really made that edition special in 03, with the blacked out tinted windows and extremely nice rims coming stock. Only 1500 of them in that year and color, and it really stands out.
    I do have a question though. Before I gave him the money, the only thing that I could find that might be wrong with it was possibly the turbo. I'm not sure if it needs to be replaced - I'm leaning towards it being fine, but I was just wondering if you're supposed to be able to hear it whistle with the windows down even with low acceleration. It certainly feels like it's got plenty off pull, and you can barely hear it with the windows up, but could somebody tell me how to audibly diagnose if its a tired turbo? ---While knowing it was possibly sounding a wee bit loud, I figured even if I had to replace the turbo it was a great deal. Plus I might be able to put a slightly bigger one on there if I do have to replace it, cause the only thing that isn't stock is the 3 inch downpipe and huge exhaust (and brake pads).
    Thanks everyone!

    The turbo whine will be considerably louder than stock with an aftermarket downpipe. If the car doesn't have a stage two tune already you should get one because it should be tuned for the downpipe (not essential on your model, but still a good idea). You should also get a catless uppipe ASAP.

    looks good and congrats. As mainframe stated, make sure you are tuned for the turbo-back exhaust.

    Oh okay, thanks a lot! How do I know if I have a stage 2 tune? Call the guy I bought it from and ask him? And I'll work on that catless uppipe - is that more for better performance or for health of the engine?
    Thank you,
    Pete

    performance and health. If the cat disintegrates then those pieces of metal go into the turbo and then your turbo is done. Calling the guy would be the easiest way. Another way would be to buy a tactirx cable and hook it up to your computer to find out if its stock or not.

    Thumbs down

    Alright so I don't think it's been tuned, but it does have a catless uppipe. The only problem with that is....that caused it to fail inspection today. Apparently every car 96 and newer needs a catalytic converter; but there must be some way to get around it if you said I needed it.

    You will either have to buy or borrow someones stock downpipe, there are 2 cats within the downpipe.

    Do you suspect a stock downpipe will fit just fine and be easy enough to put on? Thanks for all your time and help with this by the way

    Yes a stock downpipe is easy to put on. You need to pull the intercooler, turbo heat shield, then the bolts from the turbo to the downpipe, then the connection of the dp to the catback. All you need to do is figure out what size the connection of your catback is. The stock dp is a 2.5" donut gasket, and aftermarket catbacks are normally 3".

    EDIT: Actually you might be able to get away with starting at removing the bolts from the turbo to the dp as you do not have a heatshield over your turbo, I can see in the picture.

    It depends on what exhaust you have on your car whether or not the stock downpipe will mate up.

    They sell pieces you can use to mate your dp to your catback

    Depends on what exhaust. One turbo back I had in the past was solid pipe from turbo to muffler, good luck mating anything up to that.

    That thing must have weighed a ton! My catback is solid and weighs a lot. I had no idea they make complete solid turbo back.

    Weighed less than my TurboXS stealth back.. it only had one flange. Probably one of the lightest exhausts there is actually.
