5 Modifications To Reduce Engine Knock On Your WRX or STI.

Same here. I did everything on this list to my GD STI, but I will never, ever, ever go ELH. I bought Tomei's UELs to slap on once I save up more for Grimmspeeds up and downpipes, but I will never give up that rumble. Block be damned I'll build 10 more before that.

Newbie question here. What do yall mean by cams? Camshaft?

[@robk5745]

I've done hours of research, learning everything possible to add reliability to my track/street car. You've hit the mark on this one on every point. Oil and cooling are really the highlights. Don't forget a nice smooth tune and some one step colder plugs too ;)

[@Smeedia]

Definitely 🔥 a fluidamper or ATI super damper is another good one to add to the list 🙌

[@jonathanlopez1347]

Equal Length Headers + Cyl 4 Cooling Mod are a huge part of equalizing EGT across all cylinders. The Subaru EJ Knock Control System is strictly bias to Cylinder 4, as it runs 1.5 degrees of timing over over all cylinders. Essentially, Subaru's thought process is "If Cyl 4 isn't knocking, we're good." Timing is everything. It's how power is made. ELH and Cylinder 4 both contribute to a safe increase in timing, although Octane is the major contributor.

Run an oil pressure gauge would protect you from this :) Also oil temp to properly drive it warm etc. And you missed talking about the heatsoaking of the top mount :) Either get a front mount or make sure you properly drive it cool after being stuck in traffic.

I always run mine on 98 octane pump gas and a bottle of Nulon Octane booster with each tank full, which claims to raise the octane level by up to 7 points.

[@WTFibangdrums]

There’s a caveat to the radiator statement. Larger radiator is actually only helpful if it adds passes, just getting a thicker radiator with the same number of passes is hurting efficiency. You could argue more capacity, but it’s more water that the air has to pass through so it’s actually restricting air flow. If it’s adding more passes then it improves efficiency. The main benefit would be going to aluminum vs plastic would be reliability and the aluminum insulating heat better.

In your opinion, with a car like mine (stock STI down to the paper filter with 107k miles on it, well taken care of, unknown how much the previous owner pounded on it, but runs well, pulls hard, no engine oil burning, and no symptoms of oil/coolant fouling. Short of a compression test to confirm, which will get done soon, the car "seems" to be in perfect shape). And so far, the only mod I've done is an Accessport, and I'm running the Stage 1 ACN 91 map with Canadian 93 octane. 1. I plan to do the cylinder cooling mod ASAP! but how safe is to go for the occasional WOT run before this gets done? 2. Is it worth getting an AEM Dry filter to replace the stock paper filter? 3. I'm currently monitoring Coolant temp (highest its gone is 191f), feedback knock (highest it's done is -2.8, and usually only for the first second of hammering it hard on 2nd or 3rd gear), and DAM (has never gone below 1). Does that mean I am in a safe range to blast the car once in a while? 4. The ACN91 Map has 8psi on I-Drive, 14psi on S-Drive, and 17psi on S#. I am scared to try S#. Am I being paranoid? I'm tempted to try how it feels. What do you think? Awesome channel BTW, I'm soaking in all your great videos!

@@5amfishing59 After a few months of driving the car, and a couple of weeks of trying the regular 91 octane OTS tune (not the ACN 91) with both Canadian 91, and Canadian 93 and 94, I saw no difference whatsoever in the #'s reported by the AccessPort. Using 91 on the regular 91 tune did not cause any knock, or any other issues with the car. BUT since it is a higher mileage motor and I don't want to spend $5k+ right now to replace my motor, I put the ACN tune back in it, and I just use 91 octane now. I think Cobb is being VERY conservative since they probably don't want to have any controversy with Canadian customers blowing their shit up. But I'm sure there is some truth to the quality of the gas vs in the non-commie states. The car was definitely snappier on the regular 91 tune. I never tried the 93, but if I'm brave, maybe I'll try it soon with a tank of Canadian 94

@@andrewpaige9152 it's all good bro! Everyone has a different budget. Pro tunes are quiet expensive if you're to do multiple tunes, about 350 a tune usually. I'd say do it in stages if you can afford the tunes. If not, hoard all your mods then tune it in one go. Which is the route im planning on going. Since smeedia confirmed that the supporting mods don't require a tune. I'll be doing those before power mods. But I'll be running MAP stage 1 just for the extra power being fully stock.

Great video and thank you for the knowledge! I’m completely new to any car mods and STI. Just got my 2021 STI 2 weeks ago. I’m wondering is it safe to a noob like me to install all these myself or it’s better to find a professional tune/install store to do this and learn more? Would these mods void the warranty or only something touches ECU void the warranty? Great thanks again for the video! And this is actually my first ever KZbin comment after 10 yrs using it lol

[@Smeedia]

Congrats in the car and welcome back! You can definitely install these modifications yourself. None of them are too over the top difficult. Just keep in mind Subarubof America can be relatively picking with mods and warranty stuff. Always best to run by any potential mod ideas by your dealer if you plan on retaining all aspects of your warranty without issue 🙏

[@ztytom1]

Smeedia Sweet. Thanks!

What can I do with a Ej25 engine on a 2008 Impreza 2.5 non turbo automatic to ensure longevity of my car? I have a cold air intake (not short ram) and a 3' dual exhaust catback as the major modifications. The catylic converter is a walker brand about a year old and carb emission compliant with unequal length headers. The entire exhaust pipes are basically replaced as are other general maintenance parts (spark plug/wires, ignition coil, valve covers. Currently, the car is being serviced for bad compression and internal burning oil most likely it's going to be a piston/valve and seals repair. It also had a head gasket repair almost a year ago also. Currently, the car has 177,740 miles on it. Any ideas as I'm not ready to get rid of it just yet. Just a side note I replaced the spark plugs (NGK) and wires and the cars expected avg. mpg. reached as high as 30 avg. mpg

[@Smeedia]

Honestly just stay ontoo of maintance, add a catch can ans drive the car. If you really wanted you could do a larger rad but thr N/As don't have a big aftermarket standing unfortunately

[@jmt0728]

So I have an aftermarket set of unequal length headers on my sti. They are tomei ones. Is that still technically better than the stock headers? I noticed the stock headers are way more restrictive than the tomei ones and the piping size is significantly bigger on the tomei and looks like they have way higher exhaust flow. So even though equal length would be the ideal choice wouldn’t aftermarket unequal length headers still be better and still somewhat help with reducing knock? I noticed after Installing the tomei headers my overall knock decreased a good amount still.

Will I need a tune after installing an AOS?? I have a 18 Sti

[@Smeedia]

No tune needed 🙏

[@livetoberich]

when you do make the el header install, may you please record the sound from exhaust before and after and a few drive by before and after EL header installed. love the info!

[@Smeedia]

I'll make sure to get those sound clips for everyone! 😁

Would you recommend installing a AOS on a stock 2016 BRZ? Thanks

[@gizengar111]

Would an AOS void my warranty? I'm about to pick up a 2020 wrx real soon with 26k miles on it. Or should I wait until it hits 5 years or 60k miles then get an AOS?

[@theblueninjazx10r]

IAG Oil Pickup is a solid piece like Killer B. Running the IAG Oil Pickup and Killer B Windage Tray on Stock oil pan for now. Depends on what brand you want to be loyal to 😝

[@Smeedia]

Both are great choices to go with 🙌

[@skateboardgamer9875]

Question!!! Is the IAG oil pickup better then the killer b🧐

[@Smeedia]

Not really, I've used both and either option is a good choice

Yes 🙏

Would you install the v3 Crawford without coolant line for a daily drive or stay with the IAG street version ? Thanks

Stock wrx 2015-present with a fa20dit/fa24 engine has equal length headers.

Bro wat are them rims u got on ur car they look good

[@danielreimer6841]

What you think about the Crawford V3 AOS that doesn’t use coolant but is located right on top of engine to get the heat off of it?

[@Smeedia]

I think it works but out of all the options is not one of the best choices. The ones that run coolant IMO are the way to go

How important is the radiator splash guard for the bottom of the engine bay

It helps with airflow but it's not 100% needed

If I’m stock I should be fine with AOS and cooling mod?

[@trevorhedrick2647]

can i put an AOS on my 2003 wrx? if so which one would work best

[@jonphelps9472]

These all seem to void warranties too. Got 22 months left before I get a new turbo and engine. So I'll hold off

Unfortunately most will 😪

Where’s that cylinder 4 cooling mod hot spot differences link? ;)

For the Mishimoto radiator, would their cooling fans be better or the same as OEM?

They would be better, I believe they have a higher CFU than OEM
