READ THE SUB FAQ FIRST. 90% of the repetitive questions we see on this sub are answered there. Even if you don't have an issue covered in the sub FAQ it will likely help you narrow down your question. If you have a question you think should be added to the sub FAQ feel free to message any of the authors of the FAQ.

If you are troubleshooting, give us all the info we need. For example, it's best to include your year/model, any AND ALL mods, and the specific tune you are running. The more info we have, the better we are at answering questions. We also ask you try to post the question/info in the comments below before posting to the sub as a whole. This will hopefully clean up some of the really repetitive questions.

A few common posts/questions we see everyday.

Does my engine sound okay?

  • 99% of the time the answer is yes. The fa20 sounds like a tractor. It is normal.

Are these numbers on the COBB AP normal?

  • A snapshot of your AP with the DAM less than one doesn't actually tell us anything about what is going on. All it tells us is that you had a knock event that your ECU recognized and adjusted for. The most common cause for DAM drop is bad gas. Go get a fresh tank of 93/91 from shell and add a gallon or two of e85 for a full tank. I would also like to point out that knock numbers of -1.41 are super common. They can be caused by your AC kicking on and any other noise really. nothing to worry about.

This thing on the front of my engine is not spinning with the belts, is it broken?

  • That is your AC compressor clutch. It only engages when the AC is on and the compressor is running.

Let me know if you guys want any other common questions added.

Camping at a lake off the Oregon Coast. It is so doable in this car, especially with extra storage on the roof

Just picked up this beauty yesterday! 2026 WRX Premium, $33k OTD. This is my first manual car, and I’ll be driving in some semi-heavy traffic. Any tips, advice, or things I should know as a new manual driver? Thanks!

does anyone know if the 21 WRX base model wheels (17x8+55) will clear 4 pot brembos with 20mm spacers? I need to know before I order winter tires 😅

Roof spoiler Spoiler

Upvotes

I carry a bike on a hitch mount quite frequently. Would an aggressive roof spoiler have any noticeable effect of the large speed brake I’m dragging behind my car lol? I can feel the drag at highway speeds and see the bike being forced rearwards

I don’t think it’s cooked but I’m having a hard time deducing the noise. Belt? Alternator? It comes and goes so maybe even something loose?

General Question Getting Kicker Speakers in the UK

1 Upvotes

Apologies if this has been asked before but I cannot see anything via search specific to the UK.

Upgraded my head-unit from stock to something a bit better but now looking to upgrade the speakers to avoid distortion above a certain volume.

I'll admit, despite working in telecoms with copper wiring, I'm not that keen on doing extra work with adapters and wiring etc. Therefore the Kicker "plug and play" set of speakers are quite appealing.

What isn't so appealing is the cost of them on the only UK site I can find selling them, who themselves do disclose they are shipped from the US. The 4 door speakers are £330 and the tweeters £175 😵‍💫.

I can see them on SubaruOnlineParts.com for less, however when you factor in the $240 shipping cost, it comes out still over £400.

I'm thinking the answer is no, but am I missing an outlet in the UK that sells these, or will they always have to ship from the US. If so, I'm not *that* set on the plug and play option to spend that much.

Best seat and harness’ for 2015+ Wrx/Sti?

Post image
2 Upvotes

I’m wanting to put new seats in the sti that hold people better since the oem seats kinda blow, I dont want a fixed seat though since i do like let my friends and family use my car so id like something adjustable. I do like the NRG bucket seats since i like the colors but i value safety and the seat being able to move more then a color. Also with Harnesses i don’t know a thing about them but was curious what brands are good and if i need a roll cage

Heavily considering the GRC....

1 Upvotes

But a buddy of mine suggested opting for the VB WRX and modding it, including a mechanical LSD (still trying to find the exact part that would fit and if I should do this)

I reckon a lightly used WRX + some decent mods including tires, suspension, tune etc. (I usually do the work myself) would save me a lot compared to the GRC. If I do go down this path, definitely picking up the body coloured fenders to replace the plastics lol.

How do you think the WRX would hold up against the GRC long term?

Thanks guys!

Did I fuck up my car?

23 Upvotes

Bought my first car today, a 2024 wrx base model. I merged on the highway and downshifted to third gear instead of 5th. Rpm hit the red zone, 6K or more. As soon as it hit the red zone, the car kinda slowed down on its own. It drove fine after that but I’m worried I may have caused some damage that will become apparent down the line. Thoughts?

Troubleshooting 2015 Bad Turbo or Head Gasket?

1 Upvotes

I have a 2015 base with 120k that I've had since '17. Recently I've noticed if I let the car warm up and idle for 15 minutes, it smokes when I drive down the road for a bit. It's a transparent white/blueish smoke that other people have noticed. I had a Subaru master tech do a hydrocarbons test, which it failed twice, so he wants to put a head gasket on it. He also said it's rare for my engine to need a head gasket, so he's concerned it may be the Turbo going bad. Has anyone had this issue? Is there a way to determine if the Turbo is bad?
