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 🙌

[@Xavier4514]

I’ve watched this video a few years ago and I’ve installed Perrin AOS, cylinder 4 mod, Killer B oil pan +tube +tray plus other reliable mods. Still stock headers though😂 but this video helped me out then and after owning my 07 Hawkeye for three years, and still going, is still running smooth even after several Road trips from Washington state all the way down to Florida👌🏾

[@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.

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. I doubt that it does this with 98 but I still always run it for insurance. Another reason for broken ringlands is excessive timing, so maybe back off your timing a couple of degrees as well.

But however if your oil pickup breaks you are fucked...

[@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

What are your thoughts on the Baxter performance check valve system that helps get oil to the top end of the motor more quickly upon startup?

[@WRXMAN-ms2mm]

Some good recommendations there 👌. Whether you have an EJ or FA motor the AOS is a no brainer, went with IAG. A better exhaust header, specifically stainless is right up there too, the larger diameter makes the engine breath better. The one modification not on your list that both EJ and FA engines can benefit from is a Fluidampr harmonic crankshaft damper, especially if you are increasing WHP and torque. It is $$$ but a longevity extender. You may want to add it to your list!

Not a bad one to add it! Getting feedback from everyone in here just makes the lists stronger and better!

[@watch6058]

What brand would you suggest for a fluid damper? i would say the FA guys (any DI engine) would need the AOS a little more then the EJ ( not saying we don't need it cause we do) just cause of the DI and how prone to knock those motors are as well as the carbon build up on the valves nasty stuff.

[@DJSAS]

I'm buying a 2015 or 16 STI from a dealer is there anything I should be looking for. The car will have around 60 to 70 Kay's on the clock. Liked and subscribed to your channel brother.

[@Smeedia]

Appreciate the support, make sure your looking for any modifications done to the car. The last thing you want to do is buy a car that someone else had put parts on and not tuned for it, or installed incorrectly. Outside of mods, look in fender wells for rust, service history and the normal fluid levels and what not 😁

[@DJSAS]

@@Smeedia Awesome advice mate thanks for the reply and cheers from Down Under.

[@donAKAthedonjp]

Man, all of your videos are informative! Class in session when you post!

[@Smeedia]

Trying to spread the knowledge! 🤣

[@submariner6g]

Is it something to worry about if your car has been sitting for a long long while?. Oil separator.

[@Smeedia]

How long is long?

[@valkery8068]

You didn’t mention the engine oil cooler?

[@Smeedia]

I think it will help reduce knock, but for the price I dont think that it's one of the top ones. It will definitely help though!

[@diegotobar6839]

Oil temps are more of an issue with higher horse power. On stock turbo cars, not really a concern. A larger radiator is sufficient at keeping temps cooler. A larger radiator and AC delete will drop temps around 20 degrees

[@alcaraballo4211]

What size rims and tires are those in your subie

[@Smeedia]

18x9.5 +38 on a 245/35/18

[@MiLLz830]

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

[@robvicius7420]

Do you need a tune for equal length headers?

[@Smeedia]

Yes 🙏

[@robvicius7420]

@@Smeedia thank you 🙏

[@Phantaystic]

Awesome video. Going to spend this summer getting all of those installed. Then next summer, power mods. Also noob question. Would you need a tune for any of those?

[@Smeedia]

The only one you need a tune for is the ELH 😁

[@andrewpaige9152]

That's a good question... and is it worth waiting to do it in stages, like do these, then a tune then your air intake system and tune again then say boost tune again or wait till you do it all including your suspension etc then tune? Or do what you can afford for a while eg I could probably realistically afford maybe this stage stop for about 6 months save up and wack more money or should I tune between? sorry to hi jack your question man!

[@Phantaystic]

@@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.

[@banginggearsmedia]

How can it be reliable if you want to run after market Unequal length headers ie tomie UELH

[@Noname-ir7pk]

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

[@Smeedia]

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

[@djqbassic]

ok let me ask this question.What if I do the same thats on your car with cooling minus you have mishimoto radiator and I have csf. So what if i put the oem pressure cap on radiator and use mishimoto cap on turbo tank. What is the bar pressure on the mishimoto cap ? Maybe that will fix my issue ? Ive been looking at the 1.3 bar STI caps but there almost 70 dollars and i dont want to spend that much on a cap to test if it will fix my cooling. Im just trying to find that happy meduim. And with a bigger radiator I just dont think that I shouid be seeing temps above 205 degrees.

[@Smeedia]

Give this video a watch, it'll explain it wayyyy better than I can kzbin.info/www/bejne/fqvNc32wZr-Xo9k

[@djqbassic]

@@Smeedia ive watched that video 3 times now. Still doesnt help with us aftermarket radiators, and what it does to the system on bigger radiators and what changes it causes.

[@RockingItInSofia]

IAG came together with Cobb and helped them develop theirs. I run the cobb one.

[@Smeedia]

They're essentially the exact same with minor differences in the baffling but also a good choice.

[@RockingItInSofia]

@@Smeedia Yea cobb has heat shielding and a bleeder for you coolant on the AOS. Haven't had an issues yet so crossing my fingers this summer.

[@marshallsexton8996]

Just got my next 4 mods planned out.

[@Smeedia]

Solid mods to do! 🙌

[@crissalas6732]

Love your content! I haven't started any real mods on my 16 WRX. Its my daily and I am worried about the reliability. Any suggestions on simple things I can do to keep it reliable and make the car a bit more fun?

[@Smeedia]

Just stay on top of maitenencae and enjoy the car. No real simple.mods to help but just keeping fresh fluids goes a long way

[@KennedySilva06]

Just install IAG Stage 2 Oil Pump, and you are ready to go.

Thanks for making this type of videos 💪🏻

Anytime! 😁

[@LuisM-v1v]

Hi I wanna know what is the best radiator KOYO or cfs For My sti 2020?

[@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.

[@htxlui1012]

I really enjoy your format for recording your videos as well as the editing, keep it up !

[@Smeedia]

Thank you! Appreciate the feedback and the support 😁😁

[@devinantonovich1]

What about oil coolers?

[@86mnillaman]

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

[@paulmarsdensr1095]

Another good video brother. Have a good week and stay safe.

[@Smeedia]

Thank you my friend! 🙏🙏🙏

[@hudsonvalleydetail]

A good pro tune also helps.

Teying to add in the FA20 bits where I can! And thank you! Super pumped to see the 10K! 🙌

[@mr.hollywood552]

Tanner, I gotta ask and I'm not insulting your knowledge or anything at all. Just purely curious, assuming the average Joe would stick with the stock turbo on their STI (I'm an FA owner btw) why would you run an ELH on a single scroll turbo even in regards to longevity?Just purely for knowledge, thanks man. ✌🏽

[@Smeedia]

Better get Temps across cylinders 2 & 4, lowers egts so you can get better knock control and it moves the power band up a bit 🙏

[@mr.hollywood552]

@@Smeedia Sick dude, thanks! Completely unrelated question, I was hoping you might know something because I can't find any information on it. I have a CVT WRX and I'm trying to get around the ballpark range between 300-330 whp. I have all full bolt ons but I don't want to rip my cvt to shreds, so I'm trying to keep it going for as long as possible. I do know about having a good oil cooler/ cvt cooler but would you happen to know anything about aftermarket torque converters by chance? Whether its worth it or what they actually do? Can't find much info about it and I've searched everywhere. Anything helps! ✌🏽

[@ztytom1]

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!

Can the NA EJs run the Cylinder 4 cooling mod?

[@sebsshenanigans]

dang, 330 for the aos :') i got a little $20 catch can and put in some baffles in it aha. does the job. engine is still alive aha. The IAG oiling stuff, can't imagine its no good. those guys know their stuff about subarus, especially the ej's and they would have tested the hell out of them to make sure they're beyond capable aha

[@Smeedia]

Catch cans work great, just have to remember to drain them lol I've got buddy's who use old cans 😅

[@sebsshenanigans]

@@Smeedia hey, anything that catches something is better than not having anything there at all, thats my thinking :')
