THE COMEBACK

[@senc94]

DONT CALL IT A COMEBACK!! -LL Cool J

[@gameabetic]

Sooooo glad this series came back the way it did. Would like to see one of a 300zx in the future!

[@MartiniWorksOfficial]

300zx IS SUCH A GOOD CAR! Subscribe for more!

[@KAOtero22]

“…We own it now.” THE ENERGY! Got me fired up! Been following since the FI days! Your killing it Alex, thanks for being down to earth in your own channel too. I’m deciding between a 10th gen SI, civic hatch (adding an LSD) (I like the looks more than coupe or sedan lol) and the VA WRX as a DD/ beginner track day car. So glad this series is back!

[@Thequincedence]

The song. The comeback, the vibes, the approach that made me enjoy your videos so much! I hope this series stays for a while !

[@DakotaStone]

Owning the song is the biggest flex of 2023

[@codenamedesertviper1825]

THIS IS THE GREATEST COMEBACK OF 2023!!! LFG BABY!! The So You Want series is what got me into modifying cars and I am HERE for this

[@MartiniWorksOfficial]

THIS IS THE TYPE OF ENERGY WE NEED

[@JhoanciCarmona]

Pretty glad to see this come back very nostalgic to me. I love this series and you should really do a new/updated video on the Mitsubishi 3000GT. Great content man keep it up.

[@Lumlums]

All of this is valid. No shitting on the platform just straight facts. Love this kind of content, each car is unique in its own way and they all have issues of their own.

[@AlexMartini.]

Let’s make something magical again 🎉 SUBSCRIBE BOYS

[@garyharris9750]

This dude was the highlight of fitment. Thank God your back. Your channel will grow. Don't stop. Subscribed!!!

[@macrol4323]

Way more well put together than videos in the past. Really good takes in this one.

[@ebredenberg]

Love the song coming back! And the layout for the vid was great! I have the WRX as well and watch smeedia. Your points are all correct!

[@justinshute5726]

Alex and Dakota were the soul of fitment industries glad to see them killin it in new adventures. Always great content done right👍👍👍

[@sneakynut9107]

Awesome vid man and good timing! I just picked up a 2016 in January and its a blast! Got some wheels, the coils and exhaust are next. thanks for the help!

[@nilyaj]

Just know this is why I’m a fan of Alex taught me everything I know about modifying

[@derekrogers5037]

Thank you so much. The smile I had when that music started. Keep it going.

[@Gtotheyo]

I LOVE that you brought back the music! 🔥 🔥 🔥 gets the people GOIN!

[@paulhelden]

Excelent and welcome back🎉. I just got a FXT and this is very helpful

[@drummeralex9198]

Awesome way to bring the series back!

[@MartiniWorksOfficial]

Glad you enjoyed, subscribe for more of the videos coming!

[@angeloah]

Wanna know how I know you’re getting older? You favor the maintenance rule. Welcome to the top Alex, all down hill from here. When it is time to freshen up my rig I will buy from y’all and setup my build thread. Much love keep it up, this is why I listen/watch your shtuff (yes I combined shyt and stuff) my guy.

[@acid847]

Excellent video sir, I never thought I'd own a 2015 STI because they were too far out of my price range for a daily. But three months ago I decided to pick up a sketchy one with mods for 16k, and after getting a tune for the parts on the vehicle, and fixing some body issues the car runs great! Smeedia has been a great resource to maintaining an STI. My journey isn't done yet as there are still things to do but what a fun daily. Cheers!

[@SenorRobb]

Love these videos, glad to see them back! Is it possible you could do a video for the new VBs? Getting a 2023 wrx soon!

[@CoolioAlert]

333 subs, so glad to see you back!

[@SitTime]

Great vid!!! Can you please do a beginner drifting build with 350z 1. Which year 350z 2. What need to be taken out 3. What parts needed 4. Welded diff or buy one 5. Who’s KZbin channel you learn how to drift 6. Do you drift ?

[@HotBoiRicer]

Titan7’s are my go to wheel recommendations for 2015-2021 WRX/STI’s. They are the chef’s kiss🤌🏻

[@dhyatt2403]

I've adopted this recipe before buying my 2015 STi and it taste good lol

[@visionreptiles]

You should have more subs. Great video production.

[@BlooBaroo]

Matini seems like the last person to do a video like this... But its amazing none the less!

[@mustang6x285]

Just got my 2016 WRX Sport Tech and I love that thing

[@joehu2015]

Great video, thank you for making it!

[@skippylegrandgourou2069]

I 100% agree, boxer engine need a remap after modification. Jdm Subaru has to be tuned for your local gas since 100 octane is not available everywhere. Got my 1998 JDM B4 RSK tuned for 98 octane and making 330 HP.

[@jptothetree]

Your content is great 😆 Super solid delivery and editing. I'll make sure not to blow up my WRX lol

[@MartiniWorksOfficial]

Love you

[@pvtspankygaming4635]

I love these seres . And the energy smacks

[@shark2u6]

I agree with the views of this video, anything past a stage 1 tune STI should be considered not a daily driver. make sure you have another car to daily before you go above 300 at the wheels. Definitely keep up on the fluids and regular maintenance and checks. Pro tunes are definitely the way to go in that department off the shelf tunes are for getting to the Tuner.

[@mauricegramajo964]

The song! The come back!

[@natefisher1867]

This was great

[@RealSpaghetti13]

The song brought me wayyyyyy back perfect intro

[@CharlieDaMaster]

AYE THAT INTRO WAS COLD

[@WalesSvt]

Im happy this is back, any chance can Dakota bring back a version of driver to driver?

[@dose_of_j]

Yesss!! Missed this!

[@NickFinesse]

When alex said when you blowing it up I felt that, just recently blew my fa24 lol

[@paidbenss122]

The introooooo hell yeah!!

[@depl0rable_scum254]

the smeedia shoutout :)

[@generalgriffus2151]

Gotta love smeed

[@gozer1907]

Used to own an '18 Sti. Did the basic stuff, and started looking into increasing power. For "reliable" 400-450 hp, parts alone were around $14k. ($9k for IAG block Rated for 500hp). Not worth it. Throw some nice wheels and coilovers on it, catback and maybe a short shifter, and leave it alone. If you want a car with more power, WRX / Sti isn't the right choice.

[@jmsti]

IAG blocks overrated and overpriced

[@drewmiller3447]

2019 and up STI came with type RA block n internals I have a 19 with 70 k has been tuned on flex since 14 k at 487 WHP 520 TRQ SO it’s possible with the 19 n up STI no problem a lot of people making me power than me n doing just fine

[@Jeff-xx3ok]

YOOO I NEEDED THIS

[@abrill7913]

So good. The TUNE Zone, you should trademark it.

[@slacksthegreat]

How did I miss this ❤

[@jackmorrill2947]

I love this guy

[@abrahamhernandez4345]

"You like the song,we own it now" best part of the vedio.

[@zacharypotter7160]

For the AWD, 4 banger platform. Golf R seems to be the most tuner friendly for performance. But the WRX and Evo do look amazing.

[@MartiniWorksOfficial]

Golf R's are underrated honestly

[@nycyabber7103]

Yup, the EA888 can take on a lot of reliable power. Fwiw, the S3 looks pretty nice if you're into the WRX and Evo look and is the same exact car (at least 8V and MK7, the MK8 and 8Y have some slight differences). I went the S3 route just because it's cheaper than the Golf R.

[@justinshute5726]

Love my va wrx but golf r is the car I’ll be hunting for

[@triplemag124]

That intro was amazing hahahaha

[@ivrgn1720]

I MISS THIS SERIES

[@lloyddardenjr3151]

Damn this just feels right! LFG Alex!!!

[@shockzhdo2912]

Yo the intro 😭🔥

[@femiamo-appiah9236]

Honoured to be the thumbnail, entertaining as always

[@MartiniWorksOfficial]

We appreciate you letting us use that gorgeous photo!

[@femiamo-appiah9236]

Keep up the amazing content

[@corndog_5264]

when are the banners coming out my boi my focus would look great with a white one

[@dspierre28]

Love this subi gang

[@Danything123]

Sick intro

[@souza5160]

Can’t wait for you to do evo 8 and 9 !!!!!!

[@souza5160]

And I’ll say it again the best part is the intro music !!

[@MLH0214]

Alex, luv the content, the track is dope. Bringing back some of the OG flavor. Do an update on the VB. It's a great car. I own an MGM and have 57DRs. We have to agree to disagree. Rays Wheels are better quality than Eneki, that's why they cost more LOL. Would be nice to see the old crew back for a video or two.

[@justinshute5726]

Please no vb content 💩👎🤮

[@findingmovement5824]

Wonderful video!

[@MartiniWorksOfficial]

Glad you enjoyed! Subscribe for what's coming!

[@Econo.rocket]

How about a video on the Mazdaspeed protege? Nobody talks about them but they're so fun LOL

[@blackstormflow3881]

Hilarious, but so true. Thanks bro

[@njfynestnum1boi]

Well said !

[@constructapex2021]

Intro was a whole flex

[@justinbermingham2198]

You should definitley talk about Evo 8/9. Also, Blobeye>Bugeye (unless its the wagon)

[@grimmone6213]

didn’t really dig you!!! TILL YOU WERE GONE! GLAD YOUR BACK, KEEP PUSHIN HOMEZ!

[@Mrdoggy-co1og]

That song slaps though

[@LegendaryGarageYT]

As a subie owner first thing I did was aos cylinder 4 coolent mod iag oil pan/ pick up better radiator

[@stephenthompson8840]

You should put the link in the description. Also everything he said is true don’t be like me and do all the tone necessary stuff unless your car is bulletproof because you’ll break down on the way to the tune appointment. Which then leads to over a year of trying and failing to get it ready 😢

[@MartiniWorksOfficial]

The link is in the description!

[@galax1ez347]

@MartiniWorks can you do a video on modding a Fiat 124 spider

[@leombele9310]

Can you do a video on the older generations

[@melvinbrumski1446]

Been finding a lot of busted Subies in the classifieds lately, very tempting to swap in a carbed Chevy v6 and call it a day.

[@lbeqts7344]

the amount of times of cut corners for mine lmao.... but the corner cutting is catching up to me as now i have loads of problems that need addressed asap.

[@danielroman4554]

For those who own/owned a subaru wrx sti do yall recommend it??

[@babykitty90]

Like that song Long pause The most in your face speech ever heard WE OWN IT NOW

[@kevind_53]

Lets goooo🚀🌛

[@ivanmedina8487]

Yo man I’m stuck between getting a 2019 Honda accord 10th gen or 2015 Subaru wrx sti. I want to mod them but I’m not sure which to get. Can I get some help?Please!

[@goofofff]

Do I need a tune for just mufflers? (No mid pipes or anything)

[@crazyloco8844]

Love It!!!😂🎉💯😜

[@Derexwinn]

Doing an exhaust won’t hurt the car right? Like don’t need a tune or anything?

[@MoxxyEvo]

We're back baby! Hell yeah! (Do Evo X... Again)

[@MartiniWorksOfficial]

Aight bet

[@MoxxyEvo]

@@MartiniWorksOfficial Hell yeah 😎

[@damnrlly]

I agree with the video.. let’s point the obvious out. If you can’t do maintenance or keep up with scheduled maintenance work on your car.. probably shouldn’t own a car or even be thinking about doing engine modifications

[@SlyBurrito360]

Can I use that song for my gaming channel? That be Sensational 🧐☕️

[@Skopes]

That thing in the past got a 4k update!

[@Harambe_Drift]

Thank you for mentioning me.

[@justinbellavance4838]

Can you do a build on a jetta 1.8tsi

[@oscarrr9953]

Do axle back exhaust require tune for 23 wrx vb ? Since it’s just reliving back pressure stupid question I know but I rather ask then have a blown engine lmao

[@victormaciasjr.1615]

Wait even changing the radiator requires a tune? I know changing TMIC to a FMIC does. But a radiator you got me all confused lol

[@cjober6328]

Hi, 2021 wrx owner who will not modify the cars engine. Wheels, tires, suspension and a cat back and that is it. I daily my car and just use it for fun on the weekends through winding country roads

[@rudyada33]

I went crazy when I heard the song!!! My two year old is looking at me like wtf is wrong with you dad.

[@thestarswain]

Anyone know what wheels are on the first sti when the beat drops? 😅

[@GotBoostMyBoy]

Lmao never stop playing that song it gets the people going !!

[@bigslowbro]

It would be more usefull if you discussed the different engine options

[@digonderongedonga]

s/o for the MULTIPLE pieces of content dedicated to the Subaru heads LOL

[@kylewilson1011]

YESSSSSSS

[@Sope-gj2ki]

Do the engine covers actually do anything some say the actually work others say it’s doesn’t work

[@itsmetzl1097]

I've got a very clean bugeye 192k on body and trans 60k on JDM rebuild, and its my daily

[@MartiniWorksOfficial]

We also like to live dangerously

[@ballenwallen]

My 2015 has been stage 2 pro tuned since about 45k and im at 100k with no issues other than stock turbo seals and CMC gave out. With regular maintenance these cars are as reliable as anything else.
