    @jonathanlopez1347 3 года назад +22

    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.

    Got this AOS mounted, thanks for the tips! This install wasn't terrible, but def requires your patience. The mount is great because it didn't interfere with my strut bar at all. If it hasn't been said already, def keep a magnet close by, and grab a friend during the AOS mounting (most challenging part in my opinion). Other than that, everything is tight and works like a champ. Thanks again on the video!

Just proves what you highlighted in your video is exactly spot on and if undertaken, will make our Impreza WRX/STi more reliable for long term ownership 👍 👏...

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.

      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!

      @@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.

    This video is very underrated! Should be the #1 video to watch for people who drive their subbies hard....
    If you daily your Subbie you can get away with just proper regular maintenance. But however if your oil pickup breaks you are fucked...
    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.

    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!

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.

    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!

      With it all stock I wouldent worry too much, just wouldent do pulls 24/7 lol
      Imo I'd say get an SF intake over the panel filter
      And all normal values, I wouldent stress any of it 🙏

      I knew there was an exchange rate but 93 Canadian octane = CA 91 ? Lol

      @@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
