    2002 wrx boost problem or turbo

    So this is whats going on with my wrx. My radiator busted and i had to replace it. Now when I down shift to boost up so i can go faster. My rpm needle would just jump to the redline and i would have to realest my gas so i don't brake my car i don't feel any turbo boost or any thing it would just reeve up to the redline I hear it but i don't feel it moving. I can also hear my blowoff valve go off after I released my gas pedal. I really don't know whats wrong with my car my is it the turbo or my blowoff valve? please someone help its my first turbo car and I love it to death.This is my first time here so I"m a nobody sorry.

    if your letting the clutch out and the motor is free revving like its in neutral then maybe your clutch is almost toast. either from age or abuse. how many miles are on the car? ever had the clutch replaced?

    im assuming since your downshifting when this happens that you can get the car moving without any slipping?

    and try this when your cruising at speed. put the car in 4th or 5th gear and punch it. if the car reves way up almost like its not in gear then id say its possibly time for a new clutch.

    any extra info you could give would def help with the E-diagnosis.

    good luck!

    Thanks guys for the help. so what would be a good clutch kit for my 02 wrx?
    I got this car from a dealer the mileage was only 58000 now its like 61000+. It was driving well till a week ago when I had to change my radiator. I really don't know when the last owner changed the clutch on the car all i know it has some after market parts like hks blow off valve, ame cold air filter, headers and, downpipes. Any ways That's when I felt the slipping: 1
    2 3 feels ok its slightly off but works. Then when you hit 4 and 5 that when you really can tell its slipping.
    Morelman What you said is exactly whats going on when I down shift from 5th to 4th and press the gas down it reves up way to high and if I up sift and try to do the exact same thing it would reve to high.

    id say google is your friend in this case. lol

    but in all seriousness from what ive heard (anyone with more bugeye experience feel free to chime in) if your still running the stock turbo even at stg2 then your best bet is a factory clutch assembly. the stock clutch can easily handle the power and a stronger aftermarket one will only increase the shock on the drivetrain if/when you ever launch your car. this of course coupled with the 02's supposed "glass tranny" might be a recipe for disaster.

    but if you drive responsibly and are possibly planning a bigger turbo now would be the time for an upgrade though.

    Wrong title for this post it should be 02 wrx clutch kit.

    Thanks for the help ones a gain i will search up a good clutch kit for my car or just go with the oem. Other opinion would greatly help me with my decision on witch clutch i should get. Stage two or go with the original clutch. I also want to up grade turbo after clutch but I need the clutch first ill post updates on my car on what clutch I get and what turbo I will buy next. This is going to be my first build for a wrx thanks and i love this site.

    Yes, you will want to use the stock clutch for anything south of 260 awhp (or thereabouts). Even up to 300 awhp, some recommend the stock clutch. Logic: it's cheaper to replace the clutch than the transmission.

    The ACT street disk setup is a nice one, but not even remotely needed in your case.

    Stick with the stocker.

    How about changing the flywheel to a lighter flywheel with a stock clutch? Im going to change the clutch mite as well but do you think it will make any diff on my car? thanks for your help guys.

    NVM i was reading a form (Flywheel Reviews) and i think ill stick with my oem flywheel and clutch.

    I got a question what if a get a 16g turbo upgrade for my car what els will i need to complete my set up?

    Good idea. Lightweight flywheels are known to cause phantom misfire CELs in bugeyes.

    You will need 550+ cc injectors, a larger TMIC, and a larger fuel pump. If you are stock, you will also need some form of engine management and a good tune. You will also need to consider supporting mods... brakes, suspension, and driveline. Consider the possibility of replacing the bottom-end eventually.

    Most importantly, read the stickies!


    EDIT:
    Don't forget to get a compression/leakdown test performed before you slap any mods on the car.....

    Yea i paid 500 and that was from someone i know!! I can't see the pics on my work comp but you did get a factory flywheel right? or at least one with the same weight? As someone mentioned, CEL are a given (misfire and/or Crank Position sensor) and a big pain in the butt.
