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.

Joining the Fumoto Gang

The local Firestone and the local dealership fucked up the last three oil changes. Firestone forgot the crush washer for my Ascent, reused the crush washer on my WRX. The dealership left the filler cap off on the Ascent (they diagnosed the missing crush washer when we brought it in for unrelated clunking issue). So much incompetence... I used to say, not worth my effort and time to do oil changes, but now I've been hit three times in a row. Never again. Doing my own and it's Fumoto time now and forever. I guess you just need to learn first hand to become a do your own oil changes kind of guy.

WRX Cobb Titanium Cat-Back Cold Start

14 Upvotes

2020 WRX: Just got the new exhaust installed yesterday and the tone is definitely much nicer than OEM. Thinking about deleting the mufflers even though I just paid for the whole cat-back… could be louder :).

Anyone else have this exhaust & thoughts on the 🔊?

Wife was driving leisurely in town doing errands. Going up a hill and started billowing steam. When I got to her the car had cooled down. But was still steaming a little. Started right up, drove it home. On the way home it got hot twice so I pulled over and waited for it to cool down.

There’s a slight vibration. No coolant in radiator or the reservoir that holds the turbos coolant. I’m assuming it’s head gasket.

What are some other possible causes besides head gasket? Only reason I want to even hope that it’s not the head gasket is that the car ran, and still runs, completely fine.

I’m going to get one of those combustion gases test kits for the radiator tomorrow.

My FIL said it could have jumped timing, making it too advanced which would then make it run hot.

What’re my options for rebuilds? I priced out an IAG setup and that came out to like $18,000… which I do not have.

Puffing smoke on new motor

Post image
11 Upvotes

Hi Guys, I’ve got a 06 sti and recently dropped a brand 257 in it. I’ve put just less than 2000 kilometres on the new motor and have noticed smoke puffing out the exhaust, it typically happens when I’m sitting on a slant on a red traffic light or on a hill and as soon as I return to flat grounds it’s like it never happened lol. I’ve done some research and it might be the PCV that needs changing out but what are your guys’ other suggestions? Is getting the oil pan baffled also a good suggestion?

TIA 😎

Advice for an 02 WRX hybrid build.

Post image
5 Upvotes

Hey guys,

Just picked up an 02 WRX with a hybrid swap (EJ25 block, EJ20 heads, stock TD04 turbo). The previous owner was an older man and was looking to get out of a stick shift. He had lots of reciepts from the work and told me he had a mechanic do it. The build has over 3,500 miles on it and actually drives super smooth right now, but it's stuck exactly at 8 psi. I checked the vacuum lines and the restrictor pill is completely missing, so it's just running on wastegate pressure.

Neither I nor the previous owner know the exact engine internals, so I don't know if the heads were CNC machined or if it has either thicker head gaskets or hybrid pistons. I’m just assuming it's a budget build to be safe.

My goal is just a reliable, smooth street car. I want to fix the boost issue safely without buying a million parts. I'm planning to grab the OEM Subaru restrictor pill hose assembly (#14447AA090), but I need advice on the tuning side.

Honestly, since the car drives completely fine right now at 8psi, is getting a tune even a good idea at this point? Or should I just leave it alone since it's running smooth?

If tuning is the right move, instead of dropping $700 on a COBB Accessport, should I look into Open-Source tuning with a Tactrix cable? Is that even an idea I should entertain for this setup, or is an Accessport mandatory for a hybrid swap?

For anyone running a similar hybrid setup on the factory turbo, what kind of safe boost target should I tell the tuner to aim for? Also, hit me with any good E-tuner recommendations for the older GD chassis.

Thanks

WRX Intro to my WRX STI A-Line fresh from Japan

Just purchased my 2010 STI which is freshly delivered from living in Akita in Japan, it is an a-line which is an automatic that weren’t released in Aus originally. There doesn’t seem to be much info on the A-Line online so I’m hoping me making a few posts helps if someone is researching.
Previously had a 2012 WRX with the worst gear box experience I have ever had.

Thanks to the Wrx subreddit you guys saved me a ton of money and time putting in a new VVT solenoid and getting the pcv hose off with those hellish clips. Finally got everything back together this morning only to hear this whine I was for sure was something I screwed up only to find it was my power steering fluids were low. Topped that off and bled the line of air by turning my steering wheel back and forth which I learned from an earlier post on here and the sound is gone and car is running great! I said all that to say thanks guys!

Finally got rid of my worn out, stock wheel and that silly silver, lower garnish. Also glad I went with an option that retains the airbag.

Wheel is slightly smaller than stock (both grip and diameter) and feels way better in hand. Partly because of the more "premium" leather. Excited is an understatement.

I changed the engine on this 2010 Subaru wrx about 4 years ago and the transmission about 2 years ago, but when I open the oil filler cap I’ve noticed it has air comming out of it! I don’t think I’ve ever checked or opened the oil while on is this normal?

Dealer Appointment Made

1 Upvotes

As some of you know, I just bought a 2019 WRX STI. Sadly it had a recall issue for the DCM which was burning out the battery. But it also had a head unit issue (where the next track button on the screen, would continuously press itself and the only that resolved it, temporarily, was multiple hard resets). They are also doing a drive test which I'm paying for to check engine brake noise and trans. Oct 29th is the day, and I saved up a bunch in case they need to charge me (unexpected dealer charges).

The dealer is about an hour and a half away so it will be an all day event for me. But most of the worry should be covered. If not, I'll at least be provided a list to build from. If there ARE drivetrain issues, they may be covered under the used car warranty I purchased.

Lots of what ifs, but the important thing is after the DCM fix, I should be able to start driving it regularly. Thankfully I kept my 80 series Land Cruiser instead of using it for trade in value.

But if it's all fine.. I finally get to use it regularly. And that is AWESOME. Especially considering it's a ~$30k lawn ornament currently.
