  3. Maintenance, service, and repair
    2004 wrx here, so when I’m in 4th gear or like 3rd and I start to open the throttle pretty quickly at a steady pace I would say like 70% the car simply will just shutter and slowing climb trying to go past 3500 rpm’s And during this the air to fuel ratio is at 8:1. Almost like it’s just reached...

  6. General Maintenance, Troubleshooting & Accidents.
    Hey all first time poster here, I have a 2010 wrx with a turbo xs catted downpipe that is otherwise completely stock. Over the last couple weeks I’ve been noticing that the car has trouble building boost fast but still hits peak boost. I’m not sure if it’s a boost leak as I’ve done a smoke test...
  7. General Maintenance, Troubleshooting & Accidents.
    Hello all, I am extremely new to the Subaru world. I have always loved these cars since I first seen it in 2004. I just recently purchased a 2004 WRX Impreza Wagon.

  9. Everyday Impreza Talk
    Hello, I'm about to purchase a 03 Subaru Impreza wrx. In the description it says the owner tuned to boost pressure to 15 psi, is this a safe pressure or will it wear out the internals faster or damage components. Thanks for replying in advance
  10. Engine Performance
    Hello everyone, I just purchased a 2105 WRX with ~85,000 miles. The car is in great shape and only has an aftermarket intake. While driving back home on a 5 hour drive I noticed that when I go full throttle in any gear there is a hesitation in acceleration. The car either bogs down or the power...

  12. General Maintenance, Troubleshooting & Accidents.
    This is driving me nuts. I usually shift at 3k driving around the city with about 20% throttle and never fully get out of vacuum. Is this the case with everyone? Looking at my logs the closest I get is -0.9. Seems like I should be at least seeing 0 no?

    Hello all. First post here. You guys are my last hope so hopefully someone can point me in the right direction. About 2 months ago, I installed a new stage 3 clutch and 9lb aluminum billet flywheel on my 05 WRX. The car ran fine after this but my desire to continue upgrading it was...
  17. Interior Mods
    Hey guys, just read the Gauges FAQ and I was wondering if I could get your advice. Was looking at the SMY Clustermaker gauge pod and I think I'll be getting that, and I know a Boost gauge is a must, but in your opinions what other gauge is most important to have, for say a daily driver with a...
