Something I never realized as a first time subi owner, but i do now. Anything over 400whp is almost un usable on the street. The internet wants us too think 400whp is slow.

[@imoffendedthatyouareoffended]

After driving a few outrageous cars, one of them being a 2018 g wagon awd with 566 hp and tq and it was an experience for sure. But it’s useless. I think that 300 hp and tq in a car like this is absolutely more than enough. If you plan on tracking the car then obviously then it makes sense, but for daily driving even my 2020 stock wrx is more than enough.

[@AlexanderPews]

Good point, I live in Norway 🇳🇴 and own a blobeye STI.. its properly tuned, forged internals, spec-c twinscroll turbo, reversed inlet for even lower turbo lag cuz of less piping.. power? 380 hp. Its built like that to last as long as possible, but that horsepower is more than enough on the street.. I could lose my license in a few snaps of fingertips, and going full throttle.. it doesn't take long before you are already at dangerously high speeds, so yeah.. subies are lightweight and dont really need like 500-600 hp to be fun. You want usable power, not so much power that you cant use.

With driving it so much, I’ll stay catted for a while. Starting all my fueling mods and a few other support mods now.

[@Autofreakgarage]

Good move!

[@arod7130]

I really like my '14 STI hatch, but 100% agree on the fact that it is not the right platform for high HP, specially on stock block. I've done my research prior to starting my build, and come to quickly realize that it takes alot to squeeze power of these flat 4 and a comfortable/reliable number is between 350-380 WHP... of course with a $10k+ budget, a built block would get you that and more.

[@skepticalskeksis221]

It’s funny how tons of people think that EVOs can run 1000 hp. Well technically they can for like 5000 miles. A Evo motor can run reliable at 450 hp where in STI can at 400 not that big a difference.

[@joshuawagner8511]

[@isaacsanta1503]

Just to add something. I have a conversation with a over 12 years experience Subaru mechanic. The Intake change would not affect the engine. The car have a mass flow sensor. The sensor will calculate how much flow of air and the computer ajust the consumption of gas. The only thing tuning car helps is to adjust to get better performance with what you have or add.

[@khogan7281]

This. Ive run the Perrin intake with no tune for 15k miles with 0 issues. If the change of air flow were enough to cause a problem, you would throw a CEL

Other than certain parts of the longblock these Subaru STI's are super tough. I've seen 1000whp cars run multiple seasons on the stock 6 speed. The brakes are bomb, the axles are pretty dang strong, the diffs hold up to a ton of abuse, really is a great platform. Great video and I agree with all your 5 do not things though man, great video.

[@pauloquintana2511]

Disagree. these are incredible cars to build for high hp. High revving can throw all the boost at it. Either more bread or more knowledge for you my friend. Anything can be fast. And maybe you pay more than an evo or a supra. But that's just pride my friend. Rods pistons ported heads if u want. Fueling and a turbski.

[@PleadTheFifth_Racing]

@@pauloquintana2511 Ummm...that exactly what I said, these cars are great performance cars and with the right mods can make impressive numbers. Mine was making 551whp and 561whtq before I pulled the FP Green for a rotated 6870. I'll have it back together next week and we'll be shooting for low 700s on the stock motor (not for long, a built long block this summer will help push it over 1000whp).

I’d rather swap a Honda K Series into this car than try to build the EJ257 out. WAY MORE bang for the buck!

[@PleadTheFifth_Racing]

@@mr.carguy3161 Yes it is cheaper to build a Honda. Making 900whp with an LS is even cheaper and easier. Sometimes it's not about the most cost effective way to make power. The Boxer 4 cylinder is unique and a really cool driving experience. That's like comparing the I4 in my Honda Fireblade to the V4 in my Ducati Streetfighter. Both make over 200hp but they are radically different in how they make that power and how they feel to operate. Again, my Honda is cheaper to modify because it has one header, one head, one set of cams, etc. while my Ducati has two of everything.

[@dreambigaerialimaging9125]

At the 1min mark, you talk about needing a tune for a CAI. In general I agree but you go on to say there no way around it…that’s not accurate. I have a 2017 STI with a PERRIN CAI. I’ve had the car for the entire life of the vehicle thus far and had the PERRIN CAI on since like week 2. I’ve never tuned it, it’s my daily/farm car. Runs perfect. Fun fact…PERRIN is the only company that made their intakes to Subaru spec’s and as a result you end up with an intake that doesn’t require a tune. I’ve spoken to PERRIN myself to confirm (4 times, 3 different people). Like I said, in general I agree with the “CAI needs a tune!” sentiment but in this case there is no need.

[@nthgth]

That is very interesting. I don't want to tune my STI for fear of needing the engine warranty, but this could be the ticket. (Unless the intake has the same warranty drawback)

@@nthgth no noticeable difference in my opinion but I’ve talked to guys that swear it feels like it has more pep. I disagree.

I highly disagree with the lighting topic. I run the OLM Halo fog lights/ with the DRL Bezels plus LED turn signal lights, nothing too crazy. But the car looks definitely more modern.

But it also has me worried the dealership put the wrong gas in, feels like the car if pulling timing at higher boost. If anyone has suggestions i'd love to hear em, gonna run out this current tank of gas and put in the good stuff to see if it helps. Car is stock

[@Mr.Wongburger]

Came here to find 5 things I should never do with a wrx or sti. :Changing the intake without a tune. Excellent. :Putting lights on the front of your car. Personal preference. :Fully venting bov, bad. Don't do this. :Carbon fiber. Personal preference. :Catless exhaust system. Personal preference. But good advice if you aren't getting tuned. I would have liked to hear your thoughts on why with these 5 specific things to never do. 1.Intake without a tune is bad because the ecu needs to know what the new Maf scaling is because the metered air coming into the engine is being changed. Therefore your fuel needs are also changed. 2.Swapping your blow off valve which recirculates the air that has been measured by the Maf is bad. This means that if you vent the air to hear that sweet swish sound it isn't going to mix with the fuel that the maf asked for causing the engine to run rich momentarily. You can get an aftermarket bov that has recirculation function kept in. Go fast bits offers an adjustable bov that allows you to partially vent and also recirculate. All the way to fully venting. 3.Catless downpipe can cause boost creep because you are increasing the flow of exhaust out of the turbo and allowing the turbine to spin more freely. The stock waste gate and boost controller can have a tough time managing this. But that also applies to high flow cat down pipes as well. So it comes down to personal preference. If you change the stock downpipe at all you should be upgrading the boost control solenoid and getting a tune done. 4.Too many lights on the front of your car. While completely personal preference, it can lead to issues in the charging system. Having too many things drawing a load on the charging system can lead to issues with engine performance. The more voltage drawn away from your fueling and ignition system the more likely you can run into injectors not pulsing correctly and weak spark delivery. This isn't likely with oem lighting, but if you're slapping those giant light bars on adding rally style fog lights, a sub woofer and 3 amps, you can see how this can lead to issues later on. 5. Carbon fiber. Completely personal preference. If you have the money and want to slap carbon fiber everywhere that's up to you. This isn't something you should never do. If it were me adding one more to the list. Never launch your wrx or sti without slipping the clutch. The awd system isn't likely to spin the tires and you're just going to shock the shit out of your drive train. Also roll into boost after 3k rpm. Don't just jam the throttle in low rpm as it puts a lot of load on the engine. Super clean Sti, appreciate the content. 👍

What’s your opinion on the single exit exhaust on this car? My 2018 sti has the tomei ti titanium single exit with the catted downpipe, I think it looks pretty great and gives a clean sound without being too obnoxious and ricer sounding

[@jeprodigalson792]

Hmm… I agree with having an access port and tubes ready. But.. doesn’t the stock bov leak with even 3lbs of air pressure? I’ve seen so many people take them off new blow into them manually to show a leak I see a lot of pro racers ride with some of the items you complain about I prefer a lot of suspension and chassis upgrades first then stage 2 to 3 “For me personally” I think your advice is for everyday drivers vs race weekend daily drivers

[@angrychihuahua7923]

I agree with much of what you said. I like more subtle tasteful mods. Different but it looks stock or that is, something Subaru would have done. I see so many mods that really don't do much or even makes the car even slower/worse. (see mighty car mods videos) Cat-back exhaust doesn't do anything if you keep the small stock headers. It's said you need to increase HP by 15-20% in order to feel a difference and be truly faster. That's a 45-60 Hp increase! You will never use it on the street so don't bother unless you do regular track days. Doing any engine/exhaust mods will need to be tuned on a dyno. To make an STI faster takes a crapload of money. The best way to be fast is to sign up for racing school at a local track.

[@Autofreakgarage]

I would love to know what modifications he has on the car when this happened. My guess is he went stage 2 (possibly with an intake and catless) and didn't have any supporting fueling mods to accommodate the increased power. To blow a transmission on an STI is pretty uncommon. I would assume this fella launched the car 10 times a day and/or a very inexperienced manual transmission driver. I could be wrong though. There are instances when cars have had issues completely stock. However, that goes along with any performance car.

I personally use manual all the way back (loosest setting). I feel like auto implies that adjustments are being automatically made from time to time as you drive, causing wear on the parts involved with making the adjustments. (Servos and stuff)

[@barringtonrecords3976]

what about going catless just for the noise? say I go catless and dont tune the hp up too much, would that be reliable?

[@Autofreakgarage]

Definitely don’t do that. You need a tune if you change the downpipe (catted or catless).

[@barringtonrecords3976]

@@Autofreakgarage Oh thanks bro 👍 I’m still learning

[@anguswett]

For my 2020 sti: Accessport w protune Cobb intake kit Catless dp Exhaust cutout BOV Adjustable short throw What's your thoughts?

[@Autofreakgarage]

Don’t recommend going catless as I explained in the video. You would need proper fueling upgrades as well.

[@marvinabitia6874]

You will need a fuel pressure regulator, fuel pump, fuel injectors and a ebcs if you want to run safely

[@Autofreakgarage]

As well as rails and lines.

[@anguswett]

Scoobyfreak86 okay, if I were to run with cats would I be able to burble? And I don't need those fuel upgrades for stage 1 right?

[@Autofreakgarage]

Yes you can run a burble tune with stock cats, but wouldn’t recommend running it 24/7. Doing so will end up blowing the cats out. It can also cause premature turbo wear if running all the time. No you do not need fueling upgrades for stage 1.

[@isaachouse5539]

What's your wheel and suspension setup? I'm very curious. Great looking ride brother.

[@sivadharmadas4667]

Spot on video. When less is beautiful, clean spec STI. Amazing job.

[@jellyyt5946]

i’m very undecided on what to buy, at first i was all for a wrx/sti but i began looking into q50’s as well. it seems that wrx has super low reliability ratings and i don’t know why, what do you recommend? keep in mind i just want to do aesthetic mods rather than performance

[@Autofreakgarage]

I suggest watching my video on this topic. It should answer many of your questions. kzbin.info/www/bejne/aZzaZpunjqx_a6c

[@muliasido3469]

Great video! i really liked your tail lights - whats their name please? i have a new S209 and this video helped me to keep it simple!

[@Autofreakgarage]

Thanks! kzbin.info/www/bejne/gX6xc3qXjcyViNU

[@trvpluiss]

do you have tints on ur window?? If so what percent are u running? i want something that won’t be getting me inna lot of trouble

[@Autofreakgarage]

Yes 30%

[@michaelcarrafa8766]

apparently the auto transmission cant be tuned? its apparently to fragile and all im wanting to get an intake and exhaust on mine and i was told that by a tuner

[@Autofreakgarage]

The cvt is very fragile and most tuners won’t touch it.

[@jfjhtfghgfhgf]

Up pipe with ewg to prevent boost creep.

[@ZPLGarage95]

What about catless cat back and catted down pipe?

[@bryanpineda9150]

Modding these cars seems like such a troubled. I’ve never own on it I’m looking into them. It’s seem like every mod you do you could break it. Do example the air intake. I had a genesis and obviously my first mod was the air intake and I never had an issue. Is modifying this car really hard? Need help guys

[@Autofreakgarage]

[@robbiexiong3508]

Agree with everything you mentioned. I do almost exactly same with mine. Just catback for slightly different tone and remove tht nasty rasby cold start

[@patrick0uch]

Can’t get over how clean your subie looks. I’m interested in picking one up but not sure whether to buy now vs wait for the next gen. but if the next gen sti looks like the leaked images on the web... hard pass.

[@Autofreakgarage]

You might find this video useful. I go over if someone should wait for the new gen or not. kzbin.info/www/bejne/p6PEm5VphqmCgck

[@danielcastillo8802]

I ran a intake on my 16 sti with no tune for 70k miles and no issues what’s so ever.

[@Franklinevo10]

I have mine about 3 weeks now and I didn’t think I had to get a tune

[@ardikasulistija6574]

Nice wheels! what are they?

[@Autofreakgarage]

Enkei rs05rr

[@blackmantis6443]

Man I love the way you keep it simple. Nuff respect.. it is true what you say about a lot of addons.

[@carlitosverduzco88]

Man I completely agree 100% with everything you said 🎉

[@jpd3070]

Agreed! Key words "me personally" "daily driver". For me personally I do have c-light switchbacks, but kept the stock front turn signals as a safety back up in case the switchbacks fail. Couple ques. I see you're married, but don't know if you have kids. Either way how do you go about budgeting & convincing your wife not to hate you for your mod purchases? Also I see you have side skirts & rear spats but no front lip. Personal choice or in between lips? Thx! Fellow Jersey 2015+ GBP Rex driver via the shore.

[@jpd3070]

Oops just saw your end of video link for the Bayson R lip. 😎

[@Autofreakgarage]

I try to always say it’s my own opinion anytime I’m speaking about a subjective subject. People take whatever people say as the end all be all. As long as you convey is your own opinion, people tend to accept it a bit better. Yes I have 2 kids. My wife has known me since we were 18 and has known my hobby and what I do. It’s nothing new to her so a few boxes of car parts that show up at the door step is something she doesn’t question haha. She enjoys cars as well so she understands my passion. Yes I was in the middle on converting to the 2018+ front bumper so I stripped my 17 bumper down to stock and sold all the pieces off. Looks like you found my recent video on my kit I’m running. 👍🏻 local. Bennies go home.

[@l3ugl3unny10]

What’s better getting a wrx that cheaper and modify up or and Sti with slight mod ?

[@Autofreakgarage]

Depends what you want to do with the car. Personally, the STI is a far superior car in regards to overall driving experience. Wrx is cheaper to make faster than an STI. But it’s not all about horsepower. STI wins in my book everytime.

[@l3ugl3unny10]

Scoobyfreak86 thanks for the response currently looking on buying one but idk if I should get a new one or older model . What’s year u recommend between 2015-2020

[@Autofreakgarage]

2019 is my favorite year. All the updates. Better looking wheels than the 20 imho.

[@l3ugl3unny10]

Scoobyfreak86 thank you

[@Jayflex23]

Hey man just got my 2018 sti, and it came with a blow off valve unfortunately.... Am i in deep shit?

[@Autofreakgarage]

I’d be fairly concerned. It could be tuned for it, but even so. A pretty much stock ej25 should not have a bov on it. Asking for trouble.

[@Jayflex23]

@@Autofreakgarage thanks for the reply man, I'm guessing i should go to a tuner to see if it's tuned for it? Any signs i can tell it's not tuned for that bov

[@Autofreakgarage]

Did it come with an accessport? If so, most likely tuned, but you can run some data logs to send to a tuner to read. You can tell if the car is running rough or cutting if out under wot. There’s a lot of issues that can present themselves when driving. Nothing you can physically see other than the part itself.

[@Lana18177]

What’s up Scooby? Love the wheels! What’s the name of the wheels? Also what’s the of both your tire and wheel?

Me with carbon fiber front fenders and was thinking about a hood🥲

[@weberwilson6092]

And a catless pipe oof

[@markbarrett2686]

I realize you have an STI and the drivetrain is very different from a WRX but you seem to have a wealth of knowledge about popular mods and hopefully you can help me. I am going to purchase a new 2020 WRX and I don’t care for the stock shifter. I was going to have the dealer install the short throw shifter but I see there are a lot of aftermarket systems. What do you think about the difference between doing that or installing the Boomba short throw shifter. Pros vs cons? Any advice from you would be appreciated.

[@Autofreakgarage]

Go with the boomba and parts. As well as a Perrin shifter stop. It’s cheaper and you’ll get a better result over the stock ssk.

[@markbarrett2686]

Scoobyfreak86 Wow. That was fast. I was leaning towards the Boomba. I like the fact that it’s a lot shorter and cheaper. The only problem I have is how close it is to the e-brake but I could get used to it. Thank you for your time and expertise.

[@markbarrett2686]

Scoobyfreak86 What is your shifter? Stock, aftermarket, combo, ??

[@Autofreakgarage]

Kartboy

[@jerodcombs2545]

If you don't like how the boomba sts sits back and to the left (hard pass for me), check out billetworkz sts and get the shift plate as well. Definitely go with the Perrin shift stop and grab the brass shifter bushing as well. Will feel like a brand new ride 🤙

[@calvinhamilton1501]

I got a 2016 a few months ago. Whoever the previous owner was spent a lot of money under the hood, including BOV. Been wondering if it’s around that 400hp mark at least on e85 since he also did that upgrade as well

[@Autofreakgarage]

Get the car on a dyno and see what it’s pushing. Just because one car made xxx power doesn’t mean the next car will make the same power with the same mods.
