The MOST Power You Can Make With Your 2015+ Subaru STI (Reliably...)

We recently made a video showing you how to make power on your 2015+ WRX and we had a bunch of you guys ask us to make one for the STI! So, while the process is very similar, we thought we'd show you guys how to make some RELIABLE power with your 2015+ WRX STI!

[@PBJ0204]

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

2020 STi owner here.. got 10,000km out of my stock engine before the ringlands went - Subaru only offered new block replacement with a 2 month wait but wanted me to cover labour due to having a cat-back exhaust and 'over-revving' the engine. I said no thanks and had the engine built with forged pistons and so far so good! Love the car more than ever despite the disappointing factory engine being far too fragile for this day and age

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.

[@kmpaton]

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"

[@paulmarsdensr8199]

Well said. I have a 2017 base model wrx and my next car I s an STI. I am not going to upgrade my STI when I get. Stay safe brother.

[@polyscient]

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.

What I will say about the subie community is it's a mixed bag. There's stereotypes for a reason the young kids with a vape will run an ots, down pipe, intake, b.o.v, unequal length headers(it gets hot in there)no oiling or cooling mods on a stock block blow it up and blame the car...... Which is why I won't associate myself with the subie crew in my area. Bought my car knowing what it is and I'm modifying it accordingly. ie you gotta pay to play..buy it nice or buy it twice my dudes

[@Hanibul_Lecktor]

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. Emphasis needs to be driver mod properly installed. 5th Gear Automotive in Nashville Tennessee has 500+ whp 19+ STI still on the factory block. Once you control boost properly, fuel and turbo upgrades to support the power. My son's 19 STI dynos at 350whp, cat back and SF intake only. I feel like this is the second video you guys made missing the mark biggly.

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.

Stage 1 and one level up. Duh

[@LiveYourLifetv1]

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.

Shits weak son

[@mofomoco]

Sti guys are thinking why did i pay so much more for the sti when the wrx makes more ez reliable power

[@minusmartin]

though it’s true, i’m definitely not thinking that.

[@Jman-mj5nx]

If you wanna make easy power wrx if you wanna make big power sti

[@heftygainz]

No one is thinking that champ

[@CarStory]

No one who owns an STI wishes they bought a WRX. It's the other way around.

[@RealAnthonyJones]

Everyone's right, till they all realize they should've just bought the evo showing them tail lights instead.

[@tobyhuynh146]

Do something different. Buy 2015+ wrx. 6 speed swap it and mod the shit out of the fa20 engine. 🤣

[@AntilleanConfederation]

Better option is buy Sti and if it goes boom get a fa20.
