    Boost problem

    I have a 04 WRX STi completely stock with 45k km. When i am in 3rd gear and hit 3k rpm the the turbo kicks in and rev meter quickly boosts to 5k rpm unexpectidly and jerks their a while. Anyone know why this is happening? It never use to happen before. In all the other gears the revs go up constantly at the same speed.

    Could be a slipping clutch I suppose. On very open road, put it in 6th at low RPM and floor the throttle. If the tach needle jumps but the car does not accelerate, shop for a replacement clutch.

    If it has the 5 speed in it still, just use a Standard EXEDY clutch kit, make sure you machine the flywheel and install a new spiggot bearing.

    I DO NOT recommend putting any kind of Heavy Duty clutch behind the stock 5spd trans.

    Hope that helps you out,.

    upgrade your clutch. I like my ACT. That's up to you. Use a full face organic clutch. (DON'T GET PUCKS, Ceramic/Kevlar, etc)

    And don't resurface your flywheel. Subaru flywheels are disposable and not meant to be resurfaced.

    Your new clutch will come with a throwout bearing.
