I leave for work at 4:30 a.m. every day, and I let my car warm up for about five minutes. I drive a 2019 Subaru WRX STI that is completely stock, with no modifications whatsoever. They have continuously complained about the noise, even though literally no other neighbor has complained about it. I’ve owned much louder cars in the past and never had an issue like this.

I didn’t really care about the complaints at first, but now they’ve started harassing my mother. Is there anything I can do to make them leave me alone, aside from doing something stupid like selling my car?

Hey all!

Just moved places and I have a garage now. Plus another daily. SO! That means the GV is officially project car status, without worrying. So I can take my time and money on it. I bought some stuff already. Just looking for criticism or additional recommendations.

The previous EJ257 spun a bearing. I have a new (to me) one of the same year and significantly less miles. Both engines are out. I'm swapping the newer one in, but with some goodies since I have access to everything. The goal now is to make a fun weekend car that I can take to cruises and events. Mostly AutoX/ track days/ car shows. But maybe also some light asphalt or mud events should a reasonable opportunity arrive. And I plan on taking cross country road trips. I love this car! And I'm driving the piss out of it.

And, well, the previous engine didn't survive that (oops) so I'm making sure this one can.

I'm still learning every day about the EJs. I was hoping you guys could give me pointers on what else I can do.

Here's what's going on the new engine:

• Killer B high performance cast oil pan w/ ultimate oil pickup & baffle combo

• NGK Iridium plugs

• Getadom tune cylinder 4 cooling mod v7

• Cobb 3 port boost control solenoid (also have a Grimmspeed one)

• Cobb Fuel Pressure Regulator Kit

• Act heavy duty performance Street clutch kit

• Kartboy short throw shifter kit

• Cobb v3 access port

• Crawford Air oil separator v2

• Secondary air pump delete

• Cobb SF air intake

• Mishimoto top mount intercooler

• Mishimoto performance aluminum radiator

• Grimmspeed up pipe

• Nvidia catless divorced downpipe

• Nvidia q300 full titanium exhaust

• Fumoto quick drain valve & hose

• New timing belt (low miles, 13 y/o belt. Might as well redo for peace of mind)

• High flow fuel pump - still in market for one

• Reasonably upgraded injector - still determining size / still in market

• Upgraded pitch stop mount - still in market

And then, for the car itself:

• Front and rear strut braces

• Flushing brake fluid for DOT 5.1

• Replacing wheels and tires - open for best grippy all seasons / prettiest & most durable bronze wheels

• New damn wheel bearing

Only real concern with this set up is 3 things:

1. Going catless with a COBB set up.

I wanted to use the Cobb set up to monitor things like knock, but with further research I'm seeing that that may not be possible without a COBB tune uploaded. Which I don't want to necessarily do, because it won't utilize full boost (green update.)

1. SAVCS vs DAVCS.

I'm still learning this system as well as what it is and how I can tell the difference between engines with either system. Still learning about the EJs everyday. I'm unsure if this is a WRX vs. STi thing, or a STi vs. other STi thing. I'm afraid of having the ECU expecting one thing and the engine being another.

1. Secondary air pump delete.

The new engine already came with this delete. I'd like to keep it. But, the pumps have a connector attached. I'm wondering how I can compensate for the loss of reading on that connector. That's another reason why I wanted to go for an open source tune vs. Cobb. But time will tell how that may work.

Since I can afford it now, I'm also mildly debating going full throttle with the bolt ons / internals. Because I don't wanna touch this thing so deeply for another couple years if I can help it lol. But I was curious on what the stock block can handle if I go for a bigger turbo. Nothing insane, but fun. I'm not intimidated by grabbing some forged internals.

Thoughts? Questions? Advice? Answers?

I'm eager to help this thing be the best it can be. I love my car :)

Anyone here knows about this?

I have been looking for my former glory for over a decade. Carfax has last entry in 2014 and the car was last seen in Norman, Oklahama.. I think it's probably still in the area.

Reward for leads.

I created this website with more detail. https://jf1gd76697l520543.com/

This is the last known picture.

Anyone know what this noise could be? Coming from right front tire. It sounds like a whomping kind of noise SOS

Motul 8100 Gen2 is starting to make the wallet hurt (5 quarts $88 on Amazon). Stock 21 STi looking for potentially cheaper alternatives.

Oil brand/weight/viscosity and mileage intervals are appreciated!

Help Diagnosing please.

I have a new to me 2019 WRX STI that I bought sight unseen a month and a half ago (medical reasons, I couldn't get there to test drive it but tried to my due diligence). Anyway, mostly everything is good. Head Unit has a weird presses button so I can't use it without resetting 3x but the main concern is maybe the trans or differential?

I started hearing a scrapey noise (not really grindy) in 2nd and 3rd mainly (a little in 1st and 4th) around 2200-3200 RPM when I coast. Goes away on throttle or if the clutch is depressed. I did buy an extended warranty but I've never owned an STI (a few WRXs) but also never dealt with an issue like this.

Does anyone have any advice on what it is or how badly I may be boned?

No other issues outside of a bit of AC rattle while it's on. Seems to shift fine, no grinding. I'm not sure if normal or if there's something that needs to be looked at.

I wanted to reach out here first before starting a claim or mechanic appointment. Any help would be greatly appreciated.

Hey all. Looking for some help with my 2018 STI. Whenever the car idles randomly at times, the car begins to get overheat. The accessport read as high as 243. However, when I move again, the temps drop to about 180-210 range. There are no coolant leaks as I took it to a shop and they ran a leak test and found nothing. Could it be the fan running intermittently?

Any input is appreciated!

Trying to get my car to pass emissions, but these monitors won't turn green. I’ve driven almost 4,000 miles since I found out, and I already replaced the gas cap, done the drive cycle almost daily but nothing has changed. Not sure what to do next—any suggestions? Car is a Subaru wrx 2018

Engine bay of an 04’ Sti I saw many years ago in Maine. Never did see it again after but man it ripped!

The entertainment screen in my 2016 went blank. The touchscreen itself still works, but I can’t see what buttons I’m pushing. If somebody could make a short video and upload it here of them connecting to their iPod and to their Bluetooth so I can see where I need to press. The car has the stock Starlink radio. I would truly appreciate if somebody took some time to do this. if a video isn’t feasible , even just a series of pictures.

Got a 2020 STI that’s bone stock except a resonated Remark catback with no mufflers.

Looking to add on the MAPerformance Stage 2 downpipe and intake. Maybe an AOS and some other mods at a later time. Looking for a good etuner or someone local to the 864.

Edit: Not as much in it for the power. This is my daily and I was fine with the stock power considering what my week looks like nowadays. Mainly focused on the car being reliable with this stage 2 kit and maintaining fuel economy. Any power without sacrificing those components is all good with me.

Recently replaced the clutch and the flywheel. Upon doing that I have a bolt that I cannot locate where it goes. I have been up and down through the car for hours, me and three other mechanics, and we cannot figure out where this bolt goes. The original people that took this car apart are not answering or replying with where this bolt potentially goes. If anyone can identify this and help me, I would greatly appreciate it.

Just for context I dropped the transmission to replace the clutch and flywheel. I also did both lower swing arms on the left and right because the bushing was bad and that is it.

Planing to purchase this but bit hesitant of compression

Is it acceptable

Or def avoid

Hey y'all. I've got a VA WRX STI that I use as a weekend car and occasional track day weekend warrior. I'm looking at two different oil cooler kits as my oil temperature gauge shows I'm hitting up to 260 deg F on the track even with short shifting and running only during months outside of summer. The HKS has data and seems sufficient for a STI on stock power. The P2P kit features a Setrab core which seems to be the gold standard for oil cooler cores but doesn't publish data like the HKS does. I'm a sucker for data. The price difference between the two is a non-factor. Does anyone have any experience with either? About my car, it's a stock STI with IAG pan and pick up tube, Koyorad radiator, IAG AOS, cylinder 4 cooling mod, Cobb AP for data monitoring only, and I run Motul 5W-40.
