@@maverick021981 Your ringlands will blow soon. Sorry Bud. Happened to me at 350 WHP. Save yourself some potential damage and drive like a granny or get forged pistons and other beefed up internals ASAP.
2008 STI peaked at 350 whp and 360 tq before I had it detuned to 320 whp and 330 tq. The detune was to reduce injector duty cycle and increase reliability. Engine let go 8 years later with 216+ thousand miles.
What’s the longest time you held WOT without lifting to shift or whatever reason. Aka: did you ever hill climb it at 120mph+ or hold WOT for more than 10 seconds? And no if you lift to shift that’s a different scenario where oil gets to the crank more easily so im asking a different question
Been pushing 451 to the wheels for over a year now on stock block. Upgraded turbo and fuel system full e85. 378 on pump gas. Get a protune not a ots or "off the shelf" map tune. Yimi motorsports santa clarita. Mustang dyno
I own a 2019 STI and I've watch a lot of these kind of videos. I don't think upgrading the STI to make it faster is worth the money and risk. I'm keeping mine stock. I didn't buy the STI for impressive 0-60 times or for racing. I bought it for the all wheel drive and overall amazing 1990s connected feeling to the car and road. No other car feels like an STI. You have to drive one to understand.
Same as you. I have a 2020 Series White STi and the only thing done is a Cobb Catback, and that's it. When I worked at a Subaru dealership I saw so many engines grenaded by poor tuning, and that was 15 years ago. I feel its even worse now with every person with a laptop is now a "Tuner"
From experience, you're absolutely right. 2015 STI bought new in 2014 for about $45k. Since then I have blown the motor twice. Once was covered by warranty and was Subaru's fault for using trash crank bearings. The second time was after I started modifying and had 350 WHP on stock turbo and motor. It was ringland failure. Since I bought the car I have spent at least $55k repairing it and trying different upgrades. I could have bought a very fast GTR for $100k. My STI is still not as fast as I want it to be at 466 WHP. It's a huge disappointment and the worst waste of money in my life.
I have your stage 2 + on my 15STI, and I can confirm that come late fall and winter you will max out the fuel system on 93 octane. 120% IDC on WOT. I upgraded to 1050x injectors and 340lph pump and now hit 330wph 340tq at 60-70% duty cycle now.

Should say 15-18 STI, 19+ got the RA block with better ring and bearing tolerances. They hold hella lot more power reliably than any previous year. Coming from a performance channel, you definitely missed the mark on this one.

Hey there, nashville local and 19 sti owner, thats the reason i went for a 2019 as well for the upgrades you mentioned. Thanks for the info about 5th gear i will look into them, keep spreading the well informed subie info man. Well said,
19+ do NOT have the RA block. Subaru aren't stupid. Your sons 19 also does not make 350whp with catback and SF only. My 19 Sport Tech STI with the same mods, same year, on a Dynojet makes 258whp/310wtq on 94. Welcome to reality. To get 350whp, you need a fuel pump, regulator, 1050x injectors, intake and a turbo back exhaust. Lie much?
330 HP & 340 ftlb I agree. I blew a ringland at 350 WHP on my stock turbo with a tune by Cobb SoCal on Flex Fuel. I was autocrossing and had plenty of fuel injector and pump. Engine internals need to be upgraded above 330 WHP.
I make 321hp 345ftlbs catted DP and catt back exhaust, mishimoto top mount, panel filter, custom tune on 99 octane at 1.25bar. Standard Injectors and fuel pump are fine upto 390-400hp here in the UK.
@@VanIsleNuckFan I think our 99 octane is the same as the US 95 and our 97 is the same as your 93. But we have a different way of rating the octane. We also have a few garages near race tracks with 102 octane, but I've never seen or used one.

It has the 10103ad020 block instead of the previous 10103ac890. The only difference is the pistons as they're from a different manufacturer, but keep in mind they're still cast made. I've already seen 19+ STIs blow up like every other b4 it from the typical mods most dumb ass owners do to them .
@@mengdynasty6034 protune could’ve been better but it’s the piston ring that gave out. Apparently after 07 they started using cheaper material on the rings.
Hi. Great video. Very informative. I just fitted an Agency Power cat back exhaust. Feels like more power already. Next step is just what this video showed
I'm confused, the '21 STI is producing 310hp stock. Are you saying you can only add 20hp before you start running into issues? That seems like a super low ceiling.
If power was the only thing that mattered there would be no reason to drive anything that wasn't powered by a V8 at least. So sure, while you can mod the FA to 400whp, it will never be an STI. The STI is just flat out a better performance car overall.
Do what he said; add flex fuel kit from Cobb, killer headers, oil pick up and baffle, 1020 ejectors I think, plus all the other supporting mods. Add whatever reliability mods you like as well. Now go to YIMISPORT in SoCal. Let him do the rest. My STi makes 365 whp and 465 wtq on the dyno when it was 103°. It’s been tuned for 5 years and 45k now. Not a drip!

This is a bad tuner recommendation. It’s widely known you must upgrade injectors if you upgrade downpipe and intake. Injector duty cycle is probably at 99% lol.
How is the intake in rainy conditions? Do you guys sell a box to protect the filter from getting water in it? Or is the design protective enough to not allow water in
Does the downpipe have 2 cats and are they high flow cats I can't seem to find the answer and thats the only thing holding me back from the maperformance stage 2 package for my 17 sti
Have a ‘21 STI, tried searching your website for either a package deal or the parts to make this happen, with no luck. Do you have the stock for this still? I realize the video is 8 months old.
@@maperformance I know that the tune would but I’m more wondering about the intake and downpipe. I’d just uninstall the tune before going to the dealership. Do you think the intake and downpipe would void the warranty alone?
@@FreshlySnipes of course a new intake and down pipe will void warranty you just changed the design/characteristics of the engine (warranty covers stock from factory not mods) plus uninstalling the tune won't work anymore either they're hip to that now even if you re-installed OEM intake and down pipe. just accept the fact that as soon as you change and/or tune your engine say goodbye to the warranty. they'll even void your warranty now if you hit red line even when stock they're cracking down.
For the downpipe does it need to be catless or can it be catted aswell? awesome video btw thanks for the work you guys put in to make this tune reliable for these EJ's
liked my WRX it was great.....but when it comes to adding power, too many sacrifices...sacrifice low end torque to make some more peak HP...no thanks, Got a Kia Stinger GT1 , JB4 tune, 416 WHP 500WTQ
For real. You want power you have to build the block. STI is a beast of a car if you do that. Built blocks are actually reasonable and are comparative to a built K20.
its easier just to go with the direct injection 2015+ wrx with the fa20. you can make close to 400 wheel on ethanol with these motors running an ethanol blend of about e60 with the cobb flex fuel sensor and pro tuned. the sti ej motor is kind of a dinosaur but the fa20 motor will race your 380 whp k20
It’s not worth it plus y’all lie on the website it says 330 WHP on this video y’all say 330 HP stock STI makes 260 whp and 305hp honestly it felt like 315 HP not 330 at all I’m hella disappointed I wasted money on that stage 2 I also said this on Instagram and y’all didn’t say anything
A little confused by your comment here, our stage 2 93 octane tune is good for up to~300whp, we always use wheel horsepower. That can vary depending on where you live etc etc. Our stock car made 272whp / 288wtq.

I thought exactly the same thing. Plus no engine will ever perform the same. I would never use a pre program tune
How is the intake in rainy conditions? Do you guys sell a box to protect the filter from getting water in it? Or is the design protective enough to not allow water in
It gets wet
Does the downpipe have 2 cats and are they high flow cats I can't seem to find the answer and thats the only thing holding me back from the maperformance stage 2 package for my 17 sti
330whp or 330hp? Cuz 330hp is only 20 over stock... which sucks...
face it dude you wanna get 350hp+ you're gonna need a built block ....that is if you want it to last for a while.
@@redpillpusher I have a 2021 which means I have the type RA block from the factory and reinforced pistons so I should be able to handle more…
@@Gii1234 ...oooo niiiiice :)
Have a ‘21 STI, tried searching your website for either a package deal or the parts to make this happen, with no luck. Do you have the stock for this still? I realize the video is 8 months old.
Great video.
Glad you enjoyed it
0:01 how you setup the launch control to bounce on the rev limiter? when i do it, it just revs out.
iam using ots stage 1 91
Do you have Cobb Accessport V4? You need to set your launch control RPM in the menu. Try 5000 and go up if that's not high enough.
I just got a new ‘21 STI and it’s slowww lol. Will this stage 2 void my Subaru warranty??
Unfortunately, I would guess it would void your warranty.
@@maperformance I know that the tune would but I’m more wondering about the intake and downpipe. I’d just uninstall the tune before going to the dealership. Do you think the intake and downpipe would void the warranty alone?
@@FreshlySnipes of course a new intake and down pipe will void warranty you just changed the design/characteristics of the engine (warranty covers stock from factory not mods) plus uninstalling the tune won't work anymore either they're hip to that now even if you re-installed OEM intake and down pipe. just accept the fact that as soon as you change and/or tune your engine say goodbye to the warranty. they'll even void your warranty now if you hit red line even when stock they're cracking down.
305-330 is not a CRAZY power jump
extremely conservative
Making 369hp and 385ft-lb
I am still stock but a cat back
How much for the whole kit
Starting at about $850 without the Cobb Accessport!
Yess thank youu
Can you do a wrx
Already done and posted!
For the downpipe does it need to be catless or can it be catted aswell? awesome video btw thanks for the work you guys put in to make this tune reliable for these EJ's
Our downpipe is only available in catted, thanks for watching!!
liked my WRX it was great.....but when it comes to adding power, too many sacrifices...sacrifice low end torque to make some more peak HP...no thanks, Got a Kia Stinger GT1 , JB4 tune, 416 WHP 500WTQ
stingers go hard in a straight line but I bought my STi to go around corners...fast.
But 2019 is different form a 2018 Reinforce Pistons
no they aren't. Don't listen to youtubers, ask a pro.
Max RELIABLE hp? 230hp
Dont know I dont have any money to get my motor installed lol!!!!
Has anyone done this with a cobb dp & Cobb intake?
That’s what I’m wondering Cobb says their downpipe only with their stage 2 tune maxes out injectors.
I got told I needed an external wastegate to run both on cobb parts.
So the same as a wrx but these are 10k more!!!
What i got from this video , Sell Sti buy Evo X , enjoy life
425whp cobb 20g flex fuel stock motor
still running?
dam i feel sorry for subaru owners, my bone stock turbo k20 at 12lbs of boost making 380 whp with 220k miles & still pushin😂😂
For real. You want power you have to build the block. STI is a beast of a car if you do that. Built blocks are actually reasonable and are comparative to a built K20.
its easier just to go with the direct injection 2015+ wrx with the fa20. you can make close to 400 wheel on ethanol with these motors running an ethanol blend of about e60 with the cobb flex fuel sensor and pro tuned. the sti ej motor is kind of a dinosaur but the fa20 motor will race your 380 whp k20
@@ironmandingo1 if your just going for a power number sure get the FA20 wrx .... sti still a better car ..
Shout-out BaylorOG
So pretty much buy a evo instead lol
About 20 hp less than stock for a Subaru ;)))
It’s not worth it plus y’all lie on the website it says 330 WHP on this video y’all say 330 HP stock STI makes 260 whp and 305hp honestly it felt like 315 HP not 330 at all I’m hella disappointed I wasted money on that stage 2 I also said this on Instagram and y’all didn’t say anything
A little confused by your comment here, our stage 2 93 octane tune is good for up to~300whp, we always use wheel horsepower. That can vary depending on where you live etc etc. Our stock car made 272whp / 288wtq.
Evo owner here...what the hell is a "stage 2"
It's a cobb thing we wouldn't understand. But it's when you get a set of upgrades to match these tunes saved on the cobb tuner
Stage 1 and one level up. Duh
Trying to upsell people on the intakes.... for shame...
What a joke. STI’s are trash as far as building/power and takes way to much cash to build them. I regret spending 20K on mine.
Meanwhile a frikin Evo with an intake and exhaust makes 30whp with out tune. I agree our cars are trash when it comes to modding
All the 2021 STI boys just sitting here waiting and licking our lips.
Shits weak son
Do something different. Buy 2015+ wrx. 6 speed swap it and mod the shit out of the fa20 engine. 🤣
Better option is buy Sti and if it goes boom get a fa20.
1st
Sti guys are thinking why did i pay so much more for the sti when the wrx makes more ez reliable power
though it’s true, i’m definitely not thinking that.
If you wanna make easy power wrx if you wanna make big power sti
No one is thinking that champ
No one who owns an STI wishes they bought a WRX. It's the other way around.
Everyone's right, till they all realize they should've just bought the evo showing them tail lights instead.
