Modifications That Will RUIN Your Daily Driver!

[@Immortalcheese]

Your subuaru channel is like the ONLY good one out there because you actually talk succinctly and don't ramble and you're not yelling at us or acting like a total hoonigan. I'm really enjoying this content

[@Smeedia]

Eyyyy thank you 🙏🤝

[@Eri94]

I'll take quality springs and shocks over cheap Coilovers any day. I love how the Bilstein's with the Swift springs feel and drive.

[@Smeedia]

Fantastic set up 🔥

[@WRXMAN-ms2mm]

Bilstein and Eibach for me. Subaru put Bilstein on the S209.

[@Grooove_e]

I'm running Swift springs on OE replacement KYBs and it's absolutely gorgeous, still handles like a beast but maintains much of the comfort of the stock suspension

[@FatalFist]

That just goes with the saying, you get what you pay for. I don’t even trust wheels that are $200 a wheel, I’d feel like I’m driving on cardboard.

[@evan_n6136]

Same, I’m running bilstein b12’s with H&R springs. Ride quality is very close, maybe even better than stock, but feel way better in corners. Coil overs are nice if you’re tracking your car and need to be able to make adjustments for track conditions but usually overkill for daily drivers especially if you don’t know how to dial them in (which I don’t think most people do lol). Also, I used to run coil overs on my last car and during the winter the perch ring threads would get loaded up with salt and debris and became an absolute mess. Spring/shock set up is much easier to maintain imo

[@TheoRunt]

I'm so glad I found your channel when I started modding my wrx. Watching your setups and recommendations compared to using my friends advice ( he blew threw two motors in his sti) has helped me pick the right parts and is the reason why my car runs so good

[@Smeedia]

Glaf to hear that the videos have helped and hopefully your buddy doesn't blow up anymore engines 😬

[@kennethbellamy5502]

This is completely true. Before I had the money to get an Etune I was running Cobb catted dp with a k&n intake and the car ran horrible and had so many issues that I couldn't figure out but once i went and got the tune all of those problems went way and the car runs phenomenal now. Love the vids man.

[@Smeedia]

Glad to hear things got cleaned up after the tune 🥳

[@jamessanderson3498]

Etune without an accessport or is that even possible I'm have a hard time finding an for with this one

[@cynoshifter]

This is well thought out and delivered in a good way. Getting your car tuned properly for any mod is HUGE!! You can do exhaust all day and not worry, but if you touch ANYTHING on the intake side you need a tune. I would add do not get an etune if you have replaced anything. I had an appointment at fathouse fab for a dyno tune before I replaced part one. Of course part one was $6k in parts and had my check engine light on all the way there, but the drive home was fabulous!

[@Xerber85]

Excellent list and couldn’t agree more. Might I add ‘track focused mods’? Many car enthusiasts don’t seem to understand that a car set up for the track, will be a very poor daily driver street car. Examples would be track brake pads (which are generally noisy and require heating up before braking properly), solid mounts and metal bushings (which you touched on already), brake bias controllers and semi-slick tires (if you see any rain during the year).

[@Smeedia]

Ohhhh love this idea for a video! 🔥 totally agree, track built cars that are still street legal aren't always a good idea 😅

[@MrTypcyman]

Gotta give a big shout out I order a hoodie for my wife for the first engine giveaway but it unfortunately arrived with a big burn from the printer. But not the point my wife messages and was immediately taken care of with a replacement on the way so if you're even the slightest worried about buying his merchandise just know he stands behind it and makes sure everyone is happy. Thank you tanner for helping her and it's awesome to see the channel and blubaru growing.

LOVE LOVE LOVE these discussion videos! Please do a DEEP DIVE video on suspension / handling upgrades. I have almost all of the Whiteline suspension parts + BC coils on my car, and addicted to the grip! I would love a video on levels of suspension upgrades, whether (and what kind of...) chassis bracing is worth it, and what is / is not worth the $ for suspension parts. PS... I'm the white SF5 Forester you smashed on the last live stream! I promise to take better photo next time so you don't have to hum/haw about the smash lol

[@loganbandoli6534]

Yes please do this!!! I am building a 14 wrx and don’t car much for any power over 300 whp but would love for a sweet video from you on suspension upgrades so I can tear up the canyons here in Utah!

[@tattooedthinker3500]

Current set up: JDM 4/2 pots with braided lines, and BMC brace (trying to source an STI BMC if you think it’s worthwhile) BC Coilovers Whiteline sway bars + endlinks (switching to GNP end links soon) Roll centre kit + anti lift (caster) kit STi carbon Front / WL rear strut tower bars She’s a daily so open to suggestion on keeping stock bushing, or which to replace. Also looking for advice on whether (or WHEN) lower control arms / trailing arms are worth the expense. I have a set of STI aluminum control arms ready to install but want to finalize my suspension set up because that will be alignment # 3 since I keep upgrading the suspension set up :) Working on a 2.5L RS-Ti street + track weapon build next, so I’d love to hear recommendation on daily v track day suspension upgrades. Fozzy bear (my SF5) is a 2000 JDM Forester St/B. OEM+ theme inside and out. Apart from the turbo back and suspension, all OEM+ STI Type MII interior (full black/on/black), V1 STI front seats, V9 STi wheel, STI TMIC, gold BBS wheels (summer), forged pro drive wheels (winter). Just missing the SF5 STI rear seats and e-brake handle to finish the STI interior. OEM drivetrain since I cannot open source tune the OEM ECU… so big sad, and hence the RS build next

[@ItsScrambledGaming]

you have the front and rear white line sway bars and end links? I have them on my list and you seem to love them haha

[@nicknsb1064]

Ive had my Raceland Primo coilovers on my 11 WRX for about two months now and they are phenominal so far, only oddity is shock noise on the fronts. Ride quality is pretty good and they're 15-way adjustable. Only thing left to see is longevity.

[@THTRB]

Great list - I think another important thing to note about OTS maps and why I ALWAYS recommend a Pro tune or at the very least an E Tune is that not only are OTS maps a generic tune for the specific parts they are meant for (like Cobb) but every environment is different. An OTS map in a place way above sea level won’t perform the same as in a place below sea level. But a pro tune done in both of those places respectively will be fine tuned for those conditions

[@Smeedia]

Big facts, always suggest eyunes and protunes. But for those who do run ots for long term. They gotta stick to thr map notes

[@gojilover5250]

Currently laying on the couch with a sore mouth and hating every second of it but the whole “Luther the Armadillo” thing was funny and made me feel better. I love the random tangents. Thanks for temporarily making me forget about the pain.

[@Smeedia]

Glad I could be of assistance and hope ya feel better soon!

[@kzz8971]

One thing to add is polyurethane shifter bushings. I bought the Kartboy short shifter kit with those bushings and now I’m getting noticeable NVH through my shifter 😭

[@chrism1106]

Agree completely with everything on the list. Especially the tuning, I ran ots stage 1 with a catback for 7-8 years and over 100,000km between two different wrx's, and never had a single issue. The most important thing is, I'll say it louder for the kids in the back, HAVING THE RIGHT PARTS FOR THE TUNE!!! Lol. Side question because I keep getting distracted by it, but are you planning on sealing the headlight/inlet? I keep meaning to ask but always forget by the time I'm done watching the video

[@Smeedia]

No I don't, I've got another headlight set on the way. So this one will just be used for racing or shows 🙏

[@AutoXStang]

Just traded up to a 2021 STI from a 2020 WRX Premium with stage 2+. I 💯% agree with tuning!!! Tune for everything and try to stick with the same manufacturer. I went Grimmspeed everything engine wise with a Tomei cat-back and BrenTune 93shell map and loved it. Daily driven. No issues. Keep up the great content bro!!!!

[@Smeedia]

Glad to hear it has been treating you 🥳🥳

[@rudecanadian9916]

But Tanner, I put an intake, downpipe, and blowoff valve on my 16 sti on an OTS tune and it ran great! Then I cracked 2 pistons because I leaned out from my blowoff valve leaking and ended up costing me thousands. Now I'm in the process of doing it correctly so it never happens again. Learned the hard way but I learned!

[@Smeedia]

Your not alone my friend 😭😭😭

[@ogfromutube9649]

Wouldnt that richen fuel? Not lean.. As the motor is losing air post maf. meaning it thinks its getting more air then it is thus adding more fuel. Least in boost. It leans the idle with air leaks as your losing vacuum.

[@rudecanadian9916]

@@ogfromutube9649 yeah, my car ran really rich in boost and really lean on idle and at slow speeds. I assume thats what caused my pistons to get hot and when i sent it with too much boost it caused cylinders 2 and 4 ringland failures and cylinder 4 to have a few small cracks around the top of the piston

[@ogfromutube9649]

@@rudecanadian9916 ouch... I ran my aem x series wideband into stock ecu. Since it has much faster response on short term fuel trims. One time maf was dirty i noticed afr was staying in 14s under wot so immediately let off. This is why wideband arer so important on higher then stock power levels and even stock. Modern volvo uses wideband from the factory. Also have my ecu tuned to flash engine light when knock/detonation is detected. Not super sensitivie tho. If more then 2 knocks deteced in a 1 second interval it triggers and i know to let off. Or if water meth isnt triggering. Also have low windshield washer fluid light on gauge wired into methanol resevoir. Stock ecu had a 3 bar map soldered in as well as stores 2 maps that i can switch on the fly. However i did not setup safeguards to auto switch maps on knock. The main difference between the 2 maps is ignition timing. Nor do i have flex fuel sensor for fuel quality. But we have no e85 here. So i use vp racing octanium with 93 super and am able to run 39* of timing advance. My ecu also had no way to control vvt cams. So we repurposed the rear o2 preheater wires to power the vvt solenoids at certain rpm/load points as the rear o2 is disabled and am running catless downpipe. Lots of stuff you can do to save your engine. Im running 23psi on a 50mm with stock internals just wont ramp in boost til over 3k to avoid bending rods. Also my 5cyl 20v is 8.5:1 cr. Headgaskets arent really a concern until much bigger turbos. The 2.3 with 83mm bore has thick cylinder walls so cracking is less prone then the 2.5 engines with 9.5:1 cr.

[@cade_44]

@@rudecanadian9916 same thing here, put a bov on when I was in highschool bc it “sounded cool” and don’t get me wrong, it sounded awesome, but I was losing SO MUCH AIR. It was dying at idle. It had some really nice pops and bangs as well, thankfully some other minor parts went out before any real damage was done and that scared me into going back to no bov. Could’ve been much worse. Not a very smart decision😂

[@jimrustle643]

Solid info. A few other mods that can ruin your daily driver are cheap cast wheels that crack and fall apart (any size cheap rims will do this), cheap brakes and cheap brake rotors, cheap exhaust systems, and cheap ebay turbos. Every one of those listed I've seen end up bad.

[@Smeedia]

Cheap ebay turbos are a big one

[@emmanuelgalindo7594]

Tanner what about bypass valves on FA20? Does the same thing go? Is it a big no if I’m not getting it tuned cause I already had it time a year ago?

[@Smeedia]

Bypass valves are safe 🤙

[@illegalLettuce]

Local cat from Renton here! Another great vid bro! Ive never broke any of these mod guidelines myself, but one of your vids a while back talked me out of a 50/50 B.O.V. ...So I installed a cobb sf intake with their "airbox" and I hear all the bypass valve i need and am loving it on my pro-tuned cobb stage 2.5 2004 wrx wagon daily driver. A mod I say to avoid is EBAY headlights... spec-D or anything like that. They "might" look cool in daytime but at night the light output and beam pattern are SHIT and unsafe at best

[@Smeedia]

Ohhhhh EBAY headlights are always bad, they leak, have a terrible light pattern

[@Smeedia]

Yesssss going to sound good!

[@ogfromutube9649]

Totally agree on the bov!! I put upgraded diverter valve with a stainless tube inlet and open filter.. Still sounds amazing and no unaccounted for unmetered air.. The ecu assumes that air is being recirced on throttle lift. Which is how you get rich spikes on shifts. And more drop in boost during shifts as well. Mines custom tuned and even my tuner said DO NOT use a bov... Heavier spring and silicone diaphragm is all you need for higher then stock psi...

[@TheDigitalArchangel]

Great informative video! I'd like to make a suggestion, if you don't mind. When making a video involving a list, can you either put time stamps in the description, or have an indicator on the screen as to which number of the list you are on? For example, if I already know solid mounts are a bad idea on a daily, I'd like to skip ahead to the other items of the list but don't have any way of knowing where to skip to, so it's a guessing game as I skip 10 seconds ahead over and over until I hear you talk about something else, and I might miss something that I wanted to hear. Otherwise, really enjoyed the video!

[@bthrock980]

@@Smeedia now I want to be sure, in terms of reliability, the muffler delete shouldn’t affect the behavior of the car too much right?

100% agree with everything on this list I have one more huuuuge thing: 1.) If you decide to do a full "build" be brutally honest with yourself and set REALISTIC power goals. Nothing comes without a compromise. For example choose clearances that match how the car will be used. You may find yourself stuck with a noisy, piston slappy car that may be capable of big power, but it won't be a car you want to drive to work everyday.

[@RebeccaCampbell1969]

13:30 OTS Maps are just temporal If plans are to reach certain hardware: full exhaust, bigger turbo, FMIC, Freektune, etc... these, at least in my case, were achieved 5 years after buying the car... I even planned the whole thing before buying the car. So I installed the Intake, then bigger TMIC (in my case), better recycling valve... and used the first OTS map (Stage 1), then added the rest and kept climbing... specially the new fuel pump. The plan was not to use the OST, but to keep going until I could get a real tune from professionals or go to a dyno Once I did it was happiness... slow, perhaps, but I am a woman and geez installing the exhaust and specially the DP was hell and I had to ask for help

Man I know you’re crazy busy but I’m in the process of doing a rebuild with an OEM shortblock and would like to ask you a few questions. I do have the service manual. - Rocker arm sequence. 2015 wrx, they all fell when I first pulled the cam carrier. Labeled 1 and 2. Cannot find anything anywhere on them as far as a reference to what the numbers mean. Closest thing I believe I found was someone saying wear pattern is why they need to go back where they came off of. - LW Crank Pulley. You explained it in the video, however, I only ask I need to replace the OEM. OEM is $120 or so, same price as an aftermarket. Car is FBO on E60 401 whp. If oem is the way to go and it’s not worth explaining - I completely understand. - creating gaskets. Is there a way to verify or check if it’s sealed right aside from a start up?

Hey man, I liked the video. I think something you could add, and im not going through all the comments and what not to see other suggestions, but my sti, I tried to do things that were just like.... weight reduction. I thought no tune needed, I could handle it etc. 2 piece rotors, carbon fiber driveshaft, and light weight flywheel. lots of rotating mass reductions, that you wouldn't think would mess anything up, but they added up. I had driven only manual for about 10 years at that point and when descriptions of clutches say about track use only, they mean it. I killed my car a few times breaking it in, pretty embarrassing. I wont lie, once I figured it out it was very quick, but it was hard to nail down constantly. I did snap motor mounts, and went solid, and I agree with what you said (tho i like the sound and feel) I would argue motor mounts on the list, before clutches and flywheels that are arguably more "upsold", should be added to your list at the very least.

The lightweight crank is super dependent on the style of engine you have, like inline 4s will kill themselves with one, but an i6 will be perfectly fine. I remember reading somewhere that the older ejs dont even have a harmonic balancer because the boxer cycle of the engine is supposed to be self balancing

[@Smeedia]

Definitely engine depending, would still use a damper over a light weight pulley personally

[@That_Puppet]

@@Smeedia for sure, the difference between an OEM pulley set and a lightweight/underdrive pulley set is minimal at best, and the $200 or so and time spent replacing them could easily be put into something like braided steel brake lines or lightweight flywheel that will drastically increase performance

[@foxunfocused]

Yeah, the idea is balance. I know that longer living and higher revving rotaries get the rotating assembly balanced with the flywheel and crank pulley to ensure minimum front to back forces. A lightweight flywheel will throw off crank balance just as much as a lightweight pulley.

[@ogfromutube9649]

What real benefit does light crank pulley provide that a light flywheel does not?? Lightening the mass of the rotating assembly..

[@ogfromutube9649]

@@foxunfocused idk im running a ttv 11lbs chrome moly single mass flywheel as it was pinned for a better heavier sachs 707 pressure plate. Little harder to rev match and harder on the calf muscle. But once used to it, it shaves about .2 off 1/4 mile. And has less drop during shifts. Also impossible to slip even 4th gear 3500rpm launches.

This actually had useful information in it, and didn't default to common answers. Though, I would like to add: Bigger turbos (not just slightly), FMIC (on WRX hatches in cold areas) and turbo blankets. Subies already lack in low-end torque to begin with, so having a significantly bigger turbo will make it annoying in stop-and-go traffic. As for turbo blankets, they're a major fire hazard, as they're a perfect wick whenever oil gets on them. Lastly, front-mount intercoolers are fine on most Subies, except for daily driven hatches in cold weather. This is pretty niche, but it's also incredibly annoying to deal with. To install a FMIC, you need to relocate your battery into the hatch. Except, there's no mechanical backup for the hatch, so if your battery ever drains, you're nearly screwed. You have to climb through the interior (between the front seats if the rears are locked), manage to fold down the seats while you're cramped in there, get into the back and pop off a little plastic cover to even access the hatch release. And that's not even including the possibility of battery acid leaking into the interior (you should have a box, but battery acid causes rust and the fumes are highly toxic).

Tuning n00b here. How long can you go without a pro/dyno tune once you've added bolt on mods to your car? For example, say you've get an intake, AOS, BPV and catted J pipe but can't get an appointment with your pro tuner for a week or more and there isn't an OTS map for your particular mix of parts. Should you wait to install until just before your tune date, or can you get buy for a while? Also, most dyno shops want everything to be as perfect as possible before you show up; if you've just built everything, how do you ensure it will pass their pre-run inspection?

Kind of a late question but ive seen a lot of debate regarding tuning for a fully recirculating bypass valve. If youre running bone stock on sti can you use it without a tune? I know blowoff is kind of pointless for a stock motor and you absolutely should tune but the only answer i seem to find on forums is "just keep the stock one bro" or i use a 50/50 or 60/40 and its fine.

[@orig6redwings124]

As an ASE certified tech, who's been through all of this (and as an Evo X owner, which also uses a MAF sensor setup). On a stock setup, with a MAF setup, use a bypass valve (BPV), not a blow-off valve (BOV). Especially, if you don't have any supporting mods or tuning. I'm at 500 whp & still use a BPV (I'm not tuned for speed-density - i.e. no MAF sensor). You will not see any gains by tossing a BOV on a stock setup. As he mentioned in this video, installing a quality air-intake will amplify that "pffftt" blow-off sound that you're most likely looking for. Adding an upgraded BPV (Cobb), with an intake, will further enhance the sound.

@@gxbeeee I've run gfb bov on my last 3 Subaru. I've never had one leak for me personally. But those pops aren't a good sound. You should close it up I would recommend checking the adjuster screw as well to make sure it is closing quick enough. I have mine fully closed in winter and usually open it up to about 90% recirculation for summer time. The pops you are hearing are caused by running rich between shifts. The air that the maf read coming in is dumping to atmosphere and the ecu is sending the fuel it thinks it needs. Explosions in the exhaust sound fun, but they prematurely damage the turbo and catalytic converter if you have one.

There's two tabs open in my browser, one is a fluidampr, the other is a lightweight pulley set. The other side of the argument I've heard is that the dampener is only needed because manufacturers bulk produce heavy cast pulleys to keep costs down. If I'm keeping stock power and just looking for the engine to be a bit more lively under heal toe blips, is there any harm in going lightweight?

[@Smeedia]

I personally wouldn't run one, IMO the extra vibration is not worth sending into the crank. I'd take a lightweight flywheel iver a pulley any day of the week. I understand that it's less rotational mass and you get slightly better throttle response. But I'd either stay with stock or a after market damper

[@wahtay917]

@@Smeedia haha the flywheel is an open tab too. I suppose you can drop significantly more weight with just a flywheel than an entire pulley set. Alright man, thanks for advice 🤙

[@thefisch1332]

Dominic acia has a good video about how lightweight pulleys on a Subaru are a big no no

[@Mr.Wongburger]

The crank pulley is designed to balance the rotating assembly. The higher you go in Rev range the crankshaft vibrates. There are going to be specific rpms where the vibration can be damaging your bearings. The crank pulley is supposed to counter the vibrations so that doesn't happen. The fluidampr pulley will help significantly with that. I believe it's called resonance if you wanted to look into it further. You see this on fuel systems too. If you remove the fuel damper in your fuel system the opening and closing of your injectors will pulse back into the rails and fuel lines causing the fuel to stop flowing at certain rpms. To also add, the flywheel mass helps with Rev hang between shifting. If you lighten the flywheel too much, you'll gain quicker rpm and spool on the turbo but, you will drop the rpm between shifts leaving the turbos peak boost range. So you have to be really quick with the shifts or you are going to bog down between shifting.

[@user-lz3sv5sw9u]

I'd definitely go with the lightweight flywheel. I just recently put an ACT Streetlite lightweight flywheel in my 2009 Forester (non-turbo) and it's absolutely worth it. Throttle response is noticeably better, it chopped around a full second off my 0-60 time at stock power (average time is between 7.5 and 8.5s), and daily drive ability has not been impacted at all. Almost forget to mention that it has helped slightly with rev hang, but rev hang is a software issue that still needs to be tuned out manually.
