300 whp is where the car should’ve been from factory. Honestly feels great for DD. With the current mods and tune the car is perfect for what I need it for.
This! 💯
100! mine is stage 2 w/meth injection..it put down 324whp 330wtq ..it puts down 290whp wit out the methanol..I loveee the meth injection especially in summer..when temps outside r 85 degrees the iat's will be round 100degrees an wen meth kicks on they drop to 40 60degrees!
I’m at 366 WHP on E and need more power lmao.
@RyansWRX you got a FA20 motor?
Relative to EJ the FA's make power a lot more effortlessly. They come throttled from factory so as to not outshine their EJ STi counterparts.
2020 wrx 321 whp and 316 wtq. Had to swap Cobb BigSf intake for grimmspeed StealthBox. Cobb intake was screwing up my A/F ratio. Apparently, this was a common issue. So much that Cobb later released 2 revisions to the intake. Solid build man!
Should I get grimmspeed or cobb sf intake, looked at both of them but I heard Cobb more reliable because I want the stage 1+ combo with the cobb and access port
I just got my tune done yesterday! Gs intake, ebcs, and vq downpipe. Corsa 3inch exhaust with resonator delete, and TGV and EGR deletes. 285 whp 325 torque
Nice numbers! You were able to get tuned with TGV/EGR deletes?
@@ronfromportland yes. It's a Cobb tune. My tuner knows a guy in the states (were Canadian) with an older laptop that's not updated so he sent him the file. We also had to utilize the "live tuning" function within the access port to get around some things. I didn't fully understand but it worked out. 2020 wrx
@@Ghackinn man, that is awesome! 🔥
Holy crap, Subaru never contacted me about this recall! Now I have to go check that out. Thanks for mentioning this!
🙏 🙏
What recall
I have my 2017 wrx around 280-290 whp with just Cobb bigsf CAI and E30 tune by Ron at Phatbotti tuning. Not even with a 3-port EBCS yet! I know you said that ethanol is scarce where you live but if you ever get a chance to do an E30 tune, you should! Love the build and the vid man
Crazy! Thanks man! 🙏
I feel like a little over 300 hp is definitely safe but it will also make it a lot more daily Driveable Most importantly it will make your car more of your own
This! Completely agree 🙌
Cobb ecu tune and a exhaust, intercooler build is the key to maintaining the motor fo real.
Hasn’t done me wrong yet 🙌
Certainly impressive, with only 300hp and making 327ftlbs. No header or intake. Crazy, the tgv and egv deletes making that kind of torque.
No headers but intake is there. Thanks man!
@ronfromportland Sorry I meant intake manifold.
I usually don't like red cars but this one is hella clean
Thanks man!
Just got my 2019 WRX tuned at suregline bt Chris. Made 286whp and 326wtq. Upset I didnt make 300 hp aswell, but we will get there. More room to improve. Mods: MAP J-pipe catted, COBB CAI, COBB FMIC kit w/BPV, COBB EBCS, and Grimmspeed Headers and Invidia R400 catback. Really upsetting to not see 300 with all that money and mods but he assured me and made me feel better when he said 286 on a mustang dyno is about 310 on a Dyno jet. But we coming for that 300 whp😈
I would think with headers and FMIC that 300 is easy! I’m sure you’ll hit that mark sooner or later 🔥
@@ronfromportland Very well couldve hit 300 easily, but my Car was fighting and had lots of FKL. Gonna do some more matinience upgrades soon to hopefully combat the FKL. Just got my car tuned last week but we will see in a few more months when im back with standalone ECU and E85. Love your car man! Keep up the amazing vids.
what turbo? I would think the turbo size etc has to be a big factor, also injectors & fuel pump(s)
Your car comes stock wit a twin scrolled turbo. Those upgrades on a regular dyno and a better tuner would get you 310-330
@@TtopBookah ended up going catless and made 325whp. The cat being restrictive was causing some of the knock. Chris at surgeline has been great with all 4 of my WRXs dont trust anyone else. I sold my WRX tho and now have a 23 manual supra.
I was definitely wondering about what the stock clutch could take as far as power but goes lasted that long is good! Love the video homie you are inspiring a video for myself with this one!
Yessir, still running strong! Thanks man 🙌🙌
I'm at 330whp and it's still holding. I will be upgrading though because I like to be safe.
I have ~325whp for about 6 months and my clutch is starting to slip. it probably couldve held up longer if i didnt beat on it quite as much (and learned how to drive better) but that is the range where the stock clutch is a decent concern from what I've seen
the V1 Grimmspeed downpipe is louder and sounds nicer than the V2
Interesting placement for the free subaru sticker badges! Like it
Thank you!
Beautiful setup buddy love your car🔥🔥🔥🫶🏻
Thanks man! I appreciate it! 🙏 🔥
I like how the "BAD NEWS for The WRX..." video is the next recommended video
😂😂😂
i have a mod list to make 300whp. would it be enough? GS turbo inlet, perrin charge pipe, GS top mount, GS ebcs, GS stealthbox intake catted j pipe, 3" single exit(already on car).... i feel like it should crack 300 no problem. im new to the FA so im not very familiar with their potential
Hard to say but it’s definitely possible with the mods you listed out. I’d reach out to your tuner and ask for a range based on those parts. Regardless, it’ll be a lot more fun after the tune!
great video for a perfect daily driver . HKS coilovers have been working well for me .
Thank you sir! 🙏
Nice set up Ron, I’m still rocking civics like in high school just bigger motors now.. maybe we can find a car show or something to meet up and catch up sometime
Nick! Good to see you on here man! Hope you're doing well.
I had the delightful experience of playing Tokyo Extreme Racer and later Import Tuner (it's a video game series by Genki) when I was younger. Because of that game, I laugh at some of the people that don't understand this stuff. You want more HP on a turbo powered car? Intercooler, Downpipe, ECU tune, Cold air Intake, Performance exhaust system, suspension mods, transmission improvements (gears, clutches etc), downpipe, so on and so forth. To me, it's obvious. But to a lot of people, that stuff is baffling, really confusing stuff. I knew what parts I needed as soon as I bought my WRX. I knew what I wanted and I knew that I wanted X amount of horsepower.
I am halfway there now, Currently making about 275 HP with cold air intake, racing clutch, performance steering rack, pinion, STI shifter stick (stick, NOT transmission. it's still only 5 speeds but I'm alright with it, I dont plan on going too much over 300hp). I mean hell it's already a beast the last few things I gotta do are just intercooler, exhaust, Cobb and an adjustable rear wing. Finally, once that's all finished I will get some body work to remove the scratches on there from the previous owner and get the rear wing painted the same color as the car (its a 2014 Plasma Blue WRX).
I remember those games too! Glad to see that you already know what you want out of the car. Planning is key. 300 makes for a solid daily driver 👍
@@ronfromportland To be honest though I am gonna probably end up pushing it a bit. Looking to do like 300-315 hp depending on how practical it is just with those (as of now not yet aquired) parts and an ECU tune alone. The other hurdle I have to deal with is california CARB laws, which make life difficult for car enthusiasts pretty much.
btw Tokyo Xtreme Racer was so legit. they need another game series like that on the market again
got 297 WHP with Mishimoto intake grimspeed Jpipe+3port and a Etune. Will be going TMIC + chargepipe, and a grimspeed catback and a AOS
Love your videos man. Your video on issues with fuel trims with the cobb intake helped me out. I cleaned my MAF/MAP and reseated the intake but was still having issues. What helped me was reflashing my Pro tune map back onto the car and letting it relearn. Maybe the car learned while the MAF was dirty. Now my numbers fluctuate between +5/-5. By the way what companies shrouds are those? The ones on the side in the engine bay.
Thanks man! 🙏. Glad you got it sorted out, those are great numbers. The fender shrouds are from Compressive Tuning: ruclips.net/video/HA4-DIRksTo/видео.html
@@ronfromportland thanks man. Just checked them out. That price tag is actually ridiculous though. As much as I like those more i’m going to have to go with the perrin or grimm speed ones. Rather spend the money on other things! Any new mod plans for your build?
@@tehSUNMAN nothing wrong with Perrin or Grimmspeed! So far, nothing major. Trying to think of what to do next.
its a nice clean build. get those brakes in the car, you will be amazed at how much better even just a good set of pads will stop it vs. the junk factory pads.
Thanks man! Definitely on my agenda!
So my 2020 came with brembos. I don't like brembo pads. Dusty and noisy. I got a set of hawks for front and rear I'll let u know how they perform vs stock brembo pads.
Love it! Need to get to surgeline!
Thanks man! Surgeline has treated me well!
I got my 2015 WRX up to 293 hp with the Cobb stage 2 nex gen, which was great. Still running stock exhaust. What are your thoughts on exhaust? My tuning shop recommends catback but wondering if full turboback better? My shop also recommends 1 inch lowering springs and sway bars, with wheels like yours (looks fantastic dropped with those rims and tires, btw). Did you also install sway bars?
Turbo back is definitely better in terms of sound and airflow. Gotta talk to your tuner though to see which catted jpipe is able to be tuned (due to Green Speed update).
Thanks! I’m still on the stock sway bars.
3 years is promising I’ve got a similar build going on one year now.
If you don’t mind what are your feedback knock and fine knock learn on the regular?
I almost always see -1.14 and occasionally-2.81 on 30+ min drives to work. Rarely I’ll see higher but not during WOT just at random rpm ranges if I’ve been driving for long time.
Opinions on getting the knock looked into/
re-tuned would be appreciated. I’d have to loose the tgvs but I’d get the cobb intake :)

Just found your channel 🔥
subbed.
Welcome to the channel, thanks for subbing! 🔥. I regularly see -1.14 and sometimes -2.xx. Rarely ever goes beyond that. It usually registers these values when the heating/cooling turns on and I typically don’t worry about it. I had an 08 Legacy GT that would register knock (-4.xx - -7.xx on average) every time I hit the gas. That I worried about.
The catted j pipe will most likely throw a code as well. You won’t be in limp mode, but you’ll have the CEL.
Thanks guys! That’s some great peace of mind.
Hey Mario, I have a 2018 wrx with 101k miles. I just got the car 3 months ago. I started with my accessport just recently, and I see these knock numbers too.. my day was at 1 for a solid week, and then temperatures outside dropped to 30 degrees and now dam dropped to .875 and then down to. 750... im not running the car hard now, and not going to flash back. From what I've been reading these numbers are actually normal for this engine.
Just bought a 2021 WRX and scared to do any performance mods because of all the EPA issues... really wanted to get the 300hp mark in it just don't want to get myself into trouble.
Talk to a tuner bro! You’d be surprised what options are available out there to get some power.
How did you get 21hp from your intake? I was thinking about getting one, but people tend to say the give around 3-5hp with 10 being the absolute max. Did most of that hp come from the re-tune, or was it actually the intake? Love the vids btw!
A little bit of both, but it’s honestly hard to say. The intake allowed my tuner to up the power a little more if that makes sense. My tuner also mentioned during my first protune that I was limited to 282 whp and that getting an intake would bring me closer to the 300 mark. I would just get an intake to avoid wasting time and money on a re-tune. This is what I did and I regretted not getting an intake the first time. Hope this helps! Thanks for checking out the video!
@@ronfromportland thank you for the response. Just starting to figure out what to put under the hood, so any info at this point helps out a ton. Keep making great content!
Any chance you know the measurements from the fender to the middle of the wheel hub? Possibly looking into a new suspension setup so wondering about the drop
Just a little under 14” on both the front and rear.
Mustang dyno or Dynojet? My numbers were 275whp and 302wtq on mustang dyno pro tune with mishimoto intake, mishimoto big tmic, and nameless muffler delete, I know dynojet reads higher than mustang. Just wondering how big of a difference there is.
Sup man, this is off of a Mustang Dyno.
@@ronfromportland Nice. Next spring I'm installing headers and charge pipe and midpipe to complete the exhaust. Thanks to green speed update on Cobb I'm not risking a j pipe to throw codes.
thanks for another great vid
Thanks for checking it out man! 🙏 🙌
Is the lime green thing actually the oil filter or is it a cap that goes over top? Where do you get it?
It’s an oil filter cover from Perrin. Unfortunately still a prototype and I haven’t heard when they will be released ruclips.net/video/rQ7ksYREAaw/видео.html
Fbo alone is 350whp with a new turbo I can easily make 450-500whp easily but not much more if I wanna stay reliable
Awesome vid! Going the same route by the end of the month :) I was going to get the grimmspeed bpv but my tuner recommended the turbosmart bpv. How’s the grimmspeed been treating ya? And, have you heard anything good about the turbo smart bpv?
Love from jerzzzz ✌️
What’s up man! The Grimmspeed is great aside from some issues I noticed. I shipped it back to Grimmspeed to get some possible warranty work done and I’ll make an update video as soon as I get it back. I described the issues in this video ruclips.net/video/0MB6yWxwbUA/видео.html.
And nope, I haven’t had any experience with the turbosmart but they have been around for a while. Thanks for checking out the video!
Any complaints with the top mount over the front mount intercooler ?
Nope, none. I’d consider going front mount if I lived in a hot environment. Never had any issues with heat here in Portland.
I just got one and It comes in tomorrow lol I can’t wait lol but I was trying to keep it under 330 an your video and you answered all my questions lol how is it still running bro?
Welcome to the club 🔥! So far it’s still running strong. A few air fuel issues here and there but nothing I couldn’t fix on my own. Thanks for checking out the video!

@ronfromportland what shop do you take yours to I'm trying to do upgrades on mine
This sti or wrx regular? Also can someone explain is the wrx has cvt why do some pages say it has cvt im very confused by that
This is a WRX. Some WRX are equipped with CVT. This is a manual 6 speed.
Can you you
Link me the group N transmission n bushings for wrx 17’
Sure thing. Links are in the description.
Have you considered taking it to the track?
I did at one point. Bought brakes, tires, suspension, and then decided not to. AutoX was the most I did with this car.
Were u debating between other intercoolers?
I was also looking into the Verticooler but I didn’t want to spend the extra couple hundred on it. This one does the job for me.
@@ronfromportland im in the same boat. Between this and the grimmspeed since i already have the gs chargepipe
@@redrexx12 can’t go wrong with the Grimmspeed one!
Anything else worth mentioning on the Khanacooler? I’m about to pull the trigger

What kinda of oil filter is that brotha?
Subaru OEM oil filter + PERRIN oil filter cover ruclips.net/video/rQ7ksYREAaw/видео.html
So is it stage 2 or 2+? And did you keep everything fuel wish stock?
technically its stage 2+ but labeling it (stage) is a bit.... teenage-ish imho. but thats just me. hes near full bolt on with a protune. i have same mods, different brands with the addition of the header i dyno'd just a little bit higher. COBB delivery of the new EPA bs really screwed alot of people of having an easy way to get protuned. now we have to go opensource or standalone.
@@dysfunctionalveteran2510 this! 👌
^ he described it perfectly. Yup, everything with fuel is stock.
Ok cool good to know my 2021 WRX is stock I won't add any mods till warranty is up. Thanks
Parts list?
I listed it all in this older video. Cheers! ruclips.net/video/W8jmH8c21ek/видео.html
i live down in Albany, i was tuned by FTW down in Eugene literally 2 weeks before COBBs bs. i too asked for as much reliability as possible. i have all the same power mods, different brands only up on u i have is i have the Killer B header. Spool times def improved with that. not that these have much lag but its near instant with the header. i dyno'd 310/342. so far i have not had any issues. def enough power for a daily.
Good stuff. I’ve always wanted headers but just never got the chance to. Those numbers are solid, that torque must be a lot of fun.
@@ronfromportland it is nice to see someone else using ADDW1 catch cans. I think they're fantastic. I had to relocate the pcv one when I put my intercooler but other than that they have done amazing for me.
@@dysfunctionalveteran2510 glad to hear it. This brand needs more exposure for sure. Mine have been great.
What about gas consumption?
I was getting 22-25+ in the city if I drove it easy. Freeways I would hit 28-30.
Looks like I need to move to Oregon .. Cali ain’t it
I see you have the STI headlights. I was told those are not compatible with the wrx. Did you do any modifications to it ?
These are just the headlights that came stock on the WRX Limited models.
What about an aos
I have catch cans instead 🤙
@@ronfromportland aren't aos typically more ideal tho?
Not necessarily. It’s mostly personal preference. If you don’t mind emptying catch cans every now and then it’s totally fine. AOS is great but I don’t mind the minor maintenance of catch cans. ruclips.net/video/5exf0_RBb1c/видео.html
@@ronfromportland ahh I'm too lazy, I already bought an iag aos
Great choice! 🔥
damn i made 310/308 with stock intercooler
Yeah but how many pulls back to back can you do? My sti top mount was good for 400 whp however, after a couple pulls it was heat soaked. I upgraded to a gs top mount and it will do 4 pulls before it heat soaked like stock.
T T T T TODAY
?
why did you feel the need to paint the oil filter? 😂
Lol it’s a Perrin oil filter cover …
Hah gaaaaaaeeeeyyy needs uel headers
