From experience, how to get to 340-350whp on an STI: 1. Cobb AP 2. Cobb intake with box 3. Cobb catted dp 4. Cat-back exhaust 5. EBCS 6. 1050 fuel injectors 7. Fuel pump 8. Flex Fuel kit 9. Tune (tuner should up the boost to ~25psi) DONE. Extra: AOS

[@scubagto420]

boost on stock turbo to 25 psi is just over spinning the turbo making it unsafe

[@thenicaraguan]

this is basically the exact setup i got. Very excited.

[@jamesc9897]

I have that setup on 17 sti...370hp and 400 lbs with 20g turbo

[@ridetillidieharleyyamaha4063]

How much does that add up to please mate 🇦🇺👍🏻

[@aarynmurphy7174]

In Australia the AP’s arnt that big of a thing (they are starting to get bigger for the monitoring aspect) most people here just go straight for a pro tune as there cheaper and more reliable than a OTS tune, and you can set 3 to change between like a valet mode in eco then daily then your big power tune in sport sharp

[@sonicewrxsti]

Checking in 377hp on the stock ej257 . Blouch turbo , e85 and supporting mods. Few years of motoring worry free . I feel a good tune and some mechanical sympathy at times helps these for longevity a lot . Good detail video smedia

It's fun to look at these old videos. You have come so far since then. Not going to lie...needed some Dramamine for the beginning and end of this one. Much better now!

[@vballwise]

Another important thing to handle the extra power is good quality fluids too! It’s fun to go fast but it’s also good to stop too, don’t neglect brake and suspension mods

[@Smeedia]

Brake and suspension are always high on my list, but this video was geared just towards the power aspect of the car. But I definitely agree, no point in having the power of you can't properly use it!

[@creator4413]

I bought an 06 STi from a shady dealer in Washington now out of business... it blew up the same day. I didn’t have a garage at the time but I found a great shop. I was angry about everything and threw 5 figures at it over the next few months. New Forged 8.7:1 engine with bearings and head studs, Gates timing belt, killer b oil setup, tvg deletes, SRI, full exhaust (minus manifold) oil catch can, walboro 450 e85 pump, injectior dynamics 1050 set, bigger better turbo inlet & intercooler plumbing, new Blouch dominator 1.5x 8cm ceramic ball bearing turbo, new shift linkage, tein coilovers (replacing with feal struts & mild springs) group n hats, kart endlinks, whiteline center raising ball joint/rod end kit, custom tune. Stock intercooler and bpv and maxing our maf voltage still made 345hp and 325 ft/lbs. all that’s left (for power) is upgrading those and doing e85 tune or meth injection. I’m at about $15,000 right now with labor for engine build/install included. It’s the fastest car I’ve personally ever been in. It’s my fucked up baby, my repossessed rescue soobie.

Love it! Sorry to hear about the unfortunate experience though. Unfortunately I can relate. But glad that it's sorted out and your enjoying the car now 🙏🔥

[@ChasWG]

I only heard a few sound issues with this episode. I imagine you use headphones when you edit and heard it all crystal clear. In all honesty the viewers are going to be listening to this on probably their laptop speakers or maybe some music based headphones which are not the best for listening to the human voice or critical listening for sound issues. (28 years of video production and sound mixing experience here...) It wasn't that bad. Had you not said anything most would have not known anything was wrong. I did notice you added a very low music bed. Smart man! That can fix a lot of sound issues. LOL! I've often told clients who ask me if that loud sound that happened during a take can be covered with a music bed, "Yeah, some AC/DC should cover that up!' Then we reshoot the scene... Look forward to the build! I love that you tried to find everything on Amazon! Great idea. I just found a set of Goodridge braided brake lines for my 2020 WRX with CVT on Amazon. Yeah, they're different then standard trans brake lines. The park brake is way different on the CVT and that changes the rear brake calipers and lines. Anyhow, fun video man!

[@Smeedia]

Yes, I normally use headphones when editing and the echo was so bad before fixing the audio. Well I felt it was bad but I'm also very judgemental of the edits and quality. Lol love the idea of the AC/DC response 😅 Wanted to try and challenge the search a little bit more, I order a handful of parts on Amazon when I can for the free shipping 😅

[@fritziepup]

I do have to say in my experience with buying quite a ton of the same parts, the few things I've gotten from Amazon in the past few months have all had issues. Open box, wrong part, etc. If you're serious in the parts and making sure you get the best support, it's best to buy from the manufacturer direct if you can. Not only that, but most of the time it's similar in price, but the piece of mind knowing it's going to be exactly what you order now is very much worth it.

[@Smeedia]

Always good to do ypur research! And interesting the recent Amazon ones I've done have all been solid. Most are shipped and sold through thr manufacturers as well

[@fritziepup]

@@Smeedia I've just been burned too many times from Amazon in the past few months to feel comfortable ordering from their system. Even though they say they come from a manufacturer, it seems that the Amazon orders are in a lower 'tier' than others, coming from the same warehouse. I've had 2 orders from the same manufacturer come from the same warehouse even! (Returned the Amazon one being open box and missing the sensor on the AEM Gauge, other direct from manufacturer). This wasn't the first instance of it though. It seems as though a lot of the Subaru parts suppliers in the past couple years merged into the same warehouse group. The invoices all seem to come from the same place, and shipped from the same locations (KY, UT, etc).

[@Smeedia]

DI cars are much easier to get E85 to work with 🔥

[@Cobradaddy]

While a lot of the things you've listed are needed, some are not. I just did my build last year and it netted around 350 on a Mustang dyno. EWG, uppipe, intercooler, radiator, BPV, header, turbo inlet tube are all items that are not needed for this goal. Replace those with the COBB 20g turbo and you'll be better off. I didn't want the lag a even bigger turbo would bring and the extra cost, which would then need the EWG, uppipe and a extra 3k. The only thing I will prob add to my setup would be the TMIC and maybe the radiator, just because I like to buy shit I don't need, but without them I still made that power. The better spent money instead of the parts I said were not needed, is the turbo. The Stock one falls off pretty hard up top, there's a pretty big difference.

[@Smeedia]

Totally agree, ive seen people push it that high on ethanol but the VF48 sees so much stress when pushed that hard and like you said just falls on kts face in the higher power band.

[@Cobradaddy]

@@Smeedia The next step in power that was recommended on the stock block, was E85. I don't drive enough to carry that stuff in my tank that long, so I choose not to, but they did want me going bigger on the turbo which would have gone the EWG setup. I just didn't see the performance per dollar value. I did have them go colder on the plugs and delete the TVG and EGR shit. The most important in my mind was the AOS.

[@dej_photos]

I know this is an older video, but I just wanted to mention the Rev9 high-flow catted downpipe I bought when I was on more of a budget. It has served me very well. Welds on it are good, comes with a bung for your AFR already welded in, gaskets, full 3" - no complaints. My bill came out to $206.70. Between that as part of my 3" turbo-back, my GrimmSpeed intake and a pro-tune, my 2010 WRX hatch is making 313 whp and 315 fpt on a Mustang dyno.

[@henry6777]

Honestly, fuel pump, injectors, catless up and catted dp , bigger 18G turbo would be enough. Stock headers, stock IC can be kept. pump is around $180, UP/DP you can just decat it yourself or buy new ones for like $350, 1050x around $600, $1200 for the 18G and a pro tune would be enough to easily hit 350whp

Do you think 350whp is possible on stock header and downpipe (2021 STi)? If not what is a realistic goal on FBO minus header and downpipe (i.e. intake, fmic, bypass valve, internally gated, flex fuel, and fuel mods (maybe if I add FP Blue too)?

You will unless you match the Fuel pressure to stock

[@DJDekgit]

3:28 "Boost Threshold" :) aka boost target/level

[@Smeedia]

Lol thank you 😅 🔥

[@boisetkai]

What’s the different of running catted down pipe with no external wastegate to catless down pipe with uppipe with external wastegate?

[@Smeedia]

Catless downpipe will be more prone to boost creep due to the smaller IWG hole. The EWG will be able to balance out and get rid of the excess exhaust gasses. Catted downpipe with IWG is more so used in states with stricter emmisons but the cat helps create some backpressure to help keep the car from overboosting.

[@boisetkai]

Smeedia what makes you go with catless?

[@Smeedia]

I was catted 🙏

[@boisetkai]

Smeedia with out looking at the performance, what do you prefer? Catted or catless with EWG?

[@Smeedia]

Catless with an EWG set up

[@opadilla123]

I’m happy I went with my type r got 375hp and all I have is front pipe Intercooler and tune thats it ,

[@Smeedia]

🔥🔥🔥

[@ivanvillarreal8804]

Thems fighting words bro! 😯

[@ИванДинков-ъ8й]

I have sti from 2011 I want only intake and Downpipe i have good tuner but do i need something more i dont want huge boosting the car

[@avantnarde2815]

No cylinder 4 cooling mod?

[@trigun989]

Cant find an up pipe for the FA WRX. Is the only way to add an EWG is by headers?

[@Smeedia]

Yes, the FA20 does not have an up pipe so it would come off of the header

[@DREAMS2REAlITY]

I know this video is old but you mentioned having to go ewg so would you also have to pin closed the internal waste gate on the stock turbo?

[@bradgreen987]

That's a solid list. Got all those mods except the external waste gate. Planning on going E85 in a 2016 wrx. Do you reccomend that for these cars too? Thx

[@Smeedia]

Yes I do! I'm going e 85 as well have all the parts and the tune is set for may. I left out E85 because not everyone has access to it

[@jameskocks4734]

Shit! You'll make around 300 to the wheels with not much on fa on e85. You go stage 2 and run e85 on a e50 blend ive heard your making 375 to 400 on a fa. Now you do need the flexfuel harness and the proper fuel pump.Now the the problem is transmission clutch and rods if you cant drive or dont maintain. Still pay to play.

[@JJRod225]

Hey whats up bro! With the tial 38mm wga, did you use it on your stock turbo or fp?

[@Smeedia]

I used it on my FP but you can use it with a stock turbo as well you just need the eastegate bracket

[@JJRod225]

@@Smeedia ok I gotcha. I'm just wondering because when I had my evo 8, I had used external wga on my stock turbo as well but I had the turbo rebuilt and increased the hotside to the 10.5.

[@GIXXRBRAH750]

I should be making about 350 or more don’t you think? I also just got a mamba GTX2971r ball bearing

[@alcaraballo4211]

I got pretty much everything you described+A professional tune on my 2019 WRX rally blue 👍🏼 Off course ,lol and I'm a bit shy of 350hp 😉works for me and still pretty reliable. Ps,my neighbors not to happy.

[@Smeedia]

Lol.my neighbors are the same 😅 but a very usable and fun power level youve got 🔥😁

[@kimofromkalihi]

I also have identical setup on my 2017…. Invidia catless downpipe to remark muffler deletes. My neighbors bought window ac units a month later 😂

[@phillipcastro4494]

On the stock turbo Before you got the FP Blue?

[@kingmidas_fpv430]

if your going to get it tuned, then why the access port?

[@Smeedia]

Most tuners use Cobbs tuning software to tune the car so the access port is needed for them to be able to tune the car unless your doing open source tuning

[@stefanvanbraam9792]

Won’t running catless set you in the problems of not passing a smog check? Live in ky now and they don’t have them here but moving to Nevada in a month.

[@Smeedia]

Depends on the state regulations, we don't have them here in Washington, I know California would have an issue on it. Not sure about other states

[@williamslipkovich4499]

What's your wheel and tire setup?

[@Smeedia]

At thr time of this video worl emotion D9R 18x9.5 +38 on 255/40/18

[@TheXiguazhi]

I've got an STI with Invidia J pipe and catback 3" with SF Cobb Intake and just upgraded to 1050x and AEM fuel pump. My biggest issue I'm having is my LT Fuel Trims are high in AF Learn C when im cruising. Smoke tested, no leaks....do yout hink this could be because of fuel pressure regulation? It boosts fine, but it does stumble a bit between 2500-3500 RPM, especially in lower gears.

[@abelaguilera9330]

Do you need headers to run the catless downpipe safely? Or is the up pipe with the ewg enough?

[@Smeedia]

An up pipe with EWG is enough 🙏

[@TermofDeath]

I know you're against OTS maps but I have the stage 2 from MAPerformance and was wondering if I need a pro tune for a fuel pump and larger injectors.

[@Smeedia]

You will need a produce for bigger injectors, no tune is needed for a fuel pump

[@GR8GUY54]

All I wanted was a daily 2021 STI that was decent fast and without the fuel mods. Apparently an intake and catback is all you can do? No one seems to have parts yet and hopefully I don't have pay $7k just for a tune. I don't race or track my car and essentially wanted to go as fast as possible without all these extra fuel parts. Apparently you can't and need to spend $7k just get like 300ish WHP

[@damionlabounty7116]

easier way to get 340 whp in sti, you drop it off at crawford and have it tuned and put crawford aos, done

[@guillermo5701]

dude, you should totally record a video driving the sti as fast as it can pov style (in mexico obviously, wink wink)

[@Smeedia]

Will be doing a POV drive here soon but not taking it as fast as it will go 😅

[@bbelvito]

so e85 doesn't exist in my area. is 350whp is that still possible for a 2015 sti

[@Smeedia]

Yes but you'll need a different turbo 🙏

[@Plus_Frames]

At what point should I start worrying about the internals?

[@Smeedia]

Whats the car? 🙏

[@Plus_Frames]

@@Smeedia it’s a 2018 STi.

[@Smeedia]

Wouldent really send the stock block past 400 🙏

[@evlx14]

Love your videos man 👌

[@Smeedia]

Thank you! Appreciate the support! 😁

[@evlx14]

Put in more screen shots of the products if possible 😎👍 Or when you do the installs is good. Keep up the great work.

[@Smeedia]

Will do and going to record everything when we install it, appreciate the support! 🔥😁

[@triloxogy3211]

I’m a little late but what about the fuel rails, lines, and ethanol sensor for e85? Or is that not needed to go flex fuel

[@Smeedia]

All needed 🙏 some cars come with a fuel system that can handle E85 others need those parts swapped

[@dulagaferhatovic1426]

Holy shit I subscribed when you only had 1k, great content keep it up

[@ALLIX79]

Wouldn't that big a jump in power require a clutch upgrade?

[@Smeedia]

Nah, thr Stock STi clutch can hold it. We were making 401/388 on the stock clutch without issue

[@tian2339]

Damn this guy just read my mind, exactly what i have been looking at for the past couple weeks.. Not sure why i am doing this since i just got the car and want to keep it under warranty. This is additive. Couple question i have if you could help - Whats the difference between the cat and catless downpipe besides the external waste gate needed to be added? - Is the FMIC going to cause more turbo lag than the top mount? - If we are going to get tuned, will it be better to get the IAG Competition AOS? Will that just be preparing for later if we want to go higher HP? - Is updating the header to improve the airflow? Will we still be able to make the goal with UEH? - I am assuming we would put those on ourself and then have a tuner tune it right? What would be the price for that?

[@Smeedia]

Should be able to install all of these no issue, would ned a base map to drive to your tuner though. I would suggest the street series AOS. You should be able to hit these numbers with an UEL Header, I would suggest ELH for reliability purposes and the downpipe question and intercooler ones I've got super in depth videos on both of those topics 😁

[@car_man5043]

Would you have to change the internals and the block if you want to go higher than this

[@Smeedia]

400 is what I consider the safe spot for older EJs 🙏

[@loboviews4219]

What do you need to make 350 hp for a 04 blob eye?

[@Smeedia]

Cobb 20G, injectors, downpipe. Fuel pump, intake, boost controller, Ideally an intercooler, accessport, turbo inlet, TGV Deletes

[@loboviews4219]

I have a 02 bugeye wrx but man after repairing some parts on it I’ve decided to get rid of it and I’m currently waiting on a buyer. I’ve been watching your vids for a while and I’m set on getting a 2015+ wrx just to be at ease to throw on parts without worrying anything else because the car is a lot newer

[@Smeedia]

The newer WRX will be much nicer 🙏🔥

[@blurry01]

If I have a catted downpipe, do I need an upipe?

[@Smeedia]

No you do not 🙏

[@rezop52]

I owned a '14 WRX and abused the heck out of it, but never had any problems with it(aside from clutch pedal stiffing up a bit that was when I realized about the horrors' of Subies). I now own an STI and baby the heck out of the car(due to horror stories of the knock and it costing me a fortune lol) I definitely don't drive as spirited as I once used to, I guess you can say I think of the consequences now. I would love to be at a 350-360hp(I guess safe HP range) in the future. How far could I get the car to go without worrying on knock issues or blowing out the engine? I know blowing up your motor depends on how hard you drive the car so my real concern is could I get the car up to 360HP and not worry about any engine issues? Also as I said earlier I definitely don't launch at every red light anymore and I am currently working on more of a "Show" kind of build, but would love to get my build up to 340-360HP for a nice fun pull from 2-3rd gear every now and then. I'm kind of traumatized from all the horror stories about the knock and blown engines.

[@Smeedia]

Easily do-able to get the motor to make that type of power on the stock block. I pushed mine up to 401WHP without any issues on the stock block. Just make sure you add the proper longevity and reliability mods and you shouldn't have any issues. 🙌🔥

[@turbogeoduck]

Howdy! Have you done anything to help dial out the understeer? I test drove an '18 STi Limited, and was totally blown away. Except for the understeer. In a past build, I installed an adjustable rear sway bar (among other things, including coilovers). I value handling over brute power (although power is awesome, too!). I'm asking because I'm taking the STi plunge this spring, and will be buying a 2018 or newer, as stock as possible (I want to do my own modding), and likely at Subaru of Puyallup, as wifey wants me to get new or CPO if possible. Thanks for the great videos!

[@Smeedia]

Rear sway bar and a little chassis bracing helps to fix the understeer 🙏 totally understand and subaru of puyallup is the only dealer that I will go to! 🙌🔥

[@turbogeoduck]

@@Smeedia thanks for the quick response! Subaru of Puyallup is where we bought my wife's Forester, and where we get all servicing done. Love that place!
