How to make a WRX/STI Reliable

You wake up one morning, go to start your car and you hear it.... Knock...Knock....knock.... You smell the burning oil and you see your dashboard light up like a Christmas Tree..... You've done it, ya blew your engine in your Subaru.... WELL In this video Im going to show you how to avoid all of the nonsense of blowing up your engine while modifying your WRX or your STI. These tips can be cross transferred to other cars as well! Please note I am not a Subaru master mechanic by any means. But I do know these cars very well!

Having driven Subarus for 27 years as well as working in the service department at a Subaru dealer for a few of those years, I have some issues with this. Oil, trans/diff, replacement intervals are great. Acutally, the trans/diff could go every 15k. Most don't realize how hot the diff fluids actually get. It's easy, cheap insurance. I see no reason to replace coolant every 15,000 miles. Spark plugs on the other hand, can most certainly wait. You run the risk of messing up the threads in your heads by doing it more than needed. A properly tuned and maintained Subaru does not detonate anymore than any other turbocharged car, and surely not enough to damage spark plugs in my experience. If you are wearing out spark plugs, there are other issues. AOS? Meh. I don't think a properly set up one is a bad idea, but it is surely not absolutely needed. Subaru's PCV system is complex and designed to be as efficient as it could be with restraints for emissions. If you have THAT much oil getting into your intake system, there might be other issues. For a non-tracked daily driver, money could be better spent elsewhere IMHO. A tracked car is a bit of a different story. Oil pick up? I don't disagree with the fact that a KillerB pick up is great insurance, I do disagree with your excitement that someone's stock pick up WILL CRACK. There are over 200,000 WRX and WRX STi's sold in the US, plus Forester, Baja, and Legacy and Outback turbo cars as well. The amount of cracked pick ups is a fraction of a fraction of the cars that are on the road. Now, if you are paranoid, by all means, replace it. You don't want to be the "lottery winner" when it comes to cracked oil pick ups. Radiator. Unless you are doing track days, there is no good reason to spend money on a radiator. Subaru's Calsonic radiators work perfectly fine for almost everyone. I believe the older WRX STi Group N(and possibly even Group A) cars all used the oem radiator. STi does now offer a Group N radiator for the VAB cars, but it may have as much to do with not getting clogged with dirt/mud/etc as it does with actual cooling efficiency. Cooling mod I have no issue with. But it works by getting hot coolant out of the head faster, not by pumping coolant into the head. A proper tune goes without saying. But, while it's not a fail safe, I would go to a Cobb Certified Tuner. This industry is weird in the sense that anyone can call themselves a "Pro" and because they know a bit more than the customer, the customer thinks they are a genius. The end user REALLY needs to do a lot of research before they gave the local "pro" money to tune their car. I'm surprised you did not touch at all on an equal length exhaust manifold at all. Just by design, they are more efficient with removing exhaust from the engine. I am not saying unequal length manifolds are the "smoking gun" when it comes to un-reliability, but I surely would spend the money on an equal length manifold before an external wastegate if reliability is your main concern. A good piece of advice is to always use OEM parts until you can't to achieve your goals. The best tuner parts in the world cannot come close to the amount of R&D and real world testing an oem manufacturer can provide, not to mention quality and fit and finish. The farther you stray away from oem, the farther you stray away from reliabiltiy. If an EWG or oil cooler or FMIC or whatever is absolutely necessary to achieve your goals, than fine. The problem is for the vast majority of car owners, it really isn't. You may be talking about new Subarus in this video, but I would have to say the number one problem I have seen over the years is that guys buy a WRX with 120,000 miles on it want to start modding it immediately. Ever pull your coolant temp sensor to see the corrosion on it? Think your stock O2 and MAF sensors are still reading spot on? Your ECU kind of relies on your MAF for...everything. Just give it a spray with MAF cleaner, I'm sure it will be good as new. How long you going to keep driving on oem coolant hoses? Not the radiator hoses, but the heater, TB and turbo coolant hoses. How about all, and I mean ALL the vacuum lines? You think they are still nice and soft and sealing perfectly? How many times in the last 18 years do you think your coil packs fired? They begin to wear out before they actually start "missing". This is the number one problem with Subaru and reliability. Before you buy a used Subaru, you should put aside $2,000-3000(just for parts) just to get it back up to spec before you ever think about doing any modding whatsoever. These kids only see videos on "Built blocks, AOS's, EWGs, FMIC's,etc." and then get pissed because they are stranded on the side of the road because their 17 year old alternator died.

[@PQR5CHE]

IscaSullo What oil would you recommend for a 2020 STI? Thanks

[@tristansomethingsomething7059]

@IscoSullo I have a question. I just bought a 2010 impreza for a steal of a deal but besides it being stock I have no clue what maintenance has been done to it an was wondering what a 100k mile service would look like? I'm thinking spark plugs, coil packs, timing belt alignment, fuel filter. If you have anything else to add that would be awesome. Im someone that cares more about reliability then big power. Thankyou

[@lifeisgood070]

What temp does the diff hit extended driving 80mph, 100mph, 120mph? Just curious as I've had very cool tacoma differentials before. The outback differential seemed faily cool. But I've also seen some hot subaru differentials like there wasn't enough backlash or something was wrong.

Welp kinda late to say this, but don't. Plugs are not worn out or fouled at 15k, and if they are, you got bigger problems.

Subaru recommends 60K but when you start making more power I'd still suggest swapping them at 20-30K. More powers going to reduce the life span of the plugs.

Awesome energy and great advice. Thank you.

[@Smeedia]

[@Greyknight308]

Overall great video, although a few things I'd recommend differently are installing the cylinder 4 cooling mod and the oil pickup even if you are stock. The pickups can crack/break at any power level because they are garbage and the cooling mod will allow you to push your DD more reliably and its only $80. If you are considering an oil cooler, CSF racing actually makes a radiator with a built in oil cooler which is a great package. Also one of the biggest bangs for you buck as far as mods go (I know this will annoy some) is pick up a set of equal length headers, and lastly what should be common sense.... find a local reputable speed shop and talk to them about your goals to get keep your baby running happy. For oil, you really should be using a higher quality ester based oil like Motul/Redline/AMSoil/Schaeffers. They have a much higher HTHS rating and will better lubricate and protect your car, running Brotella is the oil equivalent of slapping on a VTA BOV and saying "Well my car hasn't blown up so it's not hurting anything"

[@Smeedia]

I'll look into the CSF, haven't heard of them before. If it has a built in oil cooler that's fantastic. I agree with you on the ELH, I've always swapped out for a ELH, with this car I'll be swapping to the Killer B when the time comes. I had the Perrin set on my 07 STI and they were alright ish. I use Motul for all my other fluids, I'll snag some of their 5-30 and give it a try.

Awesome video; definitely saving this one! Been in and out of the Subaru scene since about 2002, so I knew some of these already, but having just bought my first STI this summer, it's nice to have a basic rundown of what to do all in one place. Haven't done much this year other than a catback exhaust, short shifter, front and rear shifter bushings, and various little cosmetic bits, but next year I'm hoping to get a bit more into it so I really appreciate seeing your experiences with the car, as well as watching the install videos.

[@Smeedia]

Im glad that these videos are getting out there to help everyone! Ive been so consumed by Subaru that I can't get away from them. After having about 16 Subarus Ive made my fair share of mistakes over the years. Trying to get some of the good info out there that I've always seen posing up on Forums and Facebook postings covered. Really appreciate the support and its awesome to see that your getting some value out of these!

[@saviordream]

@@Smeedia Between my wife and I, the STI is our 9th Subaru, but only the 2nd one I've bothered to do any modifications to (the other being a 2018 BRZ that I had before the STI). Other than that it's been mostly various incarnations of the Legacy, and also 2 Forester turbos. Always wanted a WRX/STI, but always ended up getting something else for one reason or another.

[@Smeedia]

@@saviordream I also had a 2018 BRZ! Fun cars to drive but just super slow. I couldn't do it anymore lol ended up selling it for my old Skyline a few cars ago. Ended up coming back to Subaru after that. Totally understandable, what forester generations have you had? Ive always wanted a 2008 Forester Xt but they're unicorns up here. Glad to hear that you made it back into an STI!

[@saviordream]

@@Smeedia My wife got our first Subaru, which was a 2005 Forester XT. I got my 2015 Forester XT when I left my job at the dealership (where I had demo cars to drive). In fact, we've had nothing but Subarus since 2005, with the exception of the Evo IX MR I bought in 2006. That was a blast, and really hoping the STI gives me half the enjoyment I had with that car (so far, so good, although not nearly as fast as my modded Evo!).

[@Smeedia]

@@saviordream Evos are hard to beat when it comes to the bang for the buck, I almost bought a Evo 9 a few years back, few issues with the one I was looking at and they're so hard to find stock. The STIs have always satisfied every box that I've needed to check when it comes to a car and the newer ones are a much more adult version I think. I do miss my 2007 STI that I use to have but at a certain point you've got to keep up with the new tech that's coming out. Subarus are where Ive been, My lady just got a 2017 Impreza sport the other day and for just being an Impreza they are crazy nice now that they are on Subarus global platform.

[@Reksir]

This is a great list! I hate seeing so many subarus not well maintained espically modded out

[@Smeedia]

Ive seen too many ill maintained 😖

[@octurbojoe]

Great vid! However I must say that the GDT cooling mod pulls hot coolant out of the head via low pressure return of the heater hose and back to the water pump rather than pushing coolant into the head. The biggest factor that makes this car "unreliable" is that owners think this is a race car from the factory. It's not. End of story. Thanks for giving the community a different insight for a mod path.

[@Smeedia]

Thanks so much for the video! Only found your stuff recently but I'm really enjoying the Subie-centric content. I'm looking at modding my 2010 STI (we talked on another video of yours about transmissions) and my goal is ultimately for a "powerful, reliable daily driver". I'm looking at an AOS, oil sump, cylinder cooling, downpipe and potentially injectors. And a tune of course. Maybe the rebuild isn't as necessary as I thought, but this video suggests I'm finding some good answers and going in a good direction. My target is about 350 HP. I guess if I was adding all this stuff, I'd pretty much have to tune it upon installation, right? That goes for about $700 USD where I'm from. I can't really buy everything all at once, so what's the best way to do this? Just buy the parts, and then when I'm ready install + tune all at once? Also, does it sound like I'm picking a good path to get my EJ257 to 350HP?

For example, Mishimotos oil cooler setups come with a "Thermostatic" Sandwich adaptor that utilizes a small thermostat that allows the oil to get up to temp and circulates it similar to what you expect from your cooling system. Great for cold weather climates. Some systems use a wide open cooler which would obviously be detrimental in cold climates as oil wouldn't get up to temp, but for strictly track cars could prove useful in certain climates.

[@YocoWheelin]

Don't modify it. Problem solved.

[@Smeedia]

Well that's just no fun

[@saigoneze4465]

you can still do basic mods ie:bolt-ons only and it will not risk or change the reliability of it all

[@sleeper.simulant7327]

YocoWheelin stock EJ’s spin bearings and crack ringlands just as much as modded ones, they are ticking time bombs. You can stave off some of the factory defects with mods, such as a oil catch can, EL header, oil cooler (basically every cooling mod you can do really), and a quality protune.

[@Infamous21304]

AznPitbull 23 yeah like straight pipe it and get a cold air intake without a tune, that won’t hurt it at all

[@YocoWheelin]

You seriously mean to tell me, modding a EJ motor doesn't effect the probability of a spun bearing?

[@scoobystichris790]

Spot on buddy couldn’t agree more. You missed how important high octane fuel is on level 1. Here in the uk, 360hp (crank) is about max you should but through your stock internals. Some are running 380-390hp with no issues in stock internals, but if you drive like a granny it will last. 👍

[@Smeedia]

Assumed that it was a given that people need to use the correct fuel, however you are right have to make sure the proper fuel is used and without doing so will jeopardize the integrity of your car

[@OG_DSM]

Looked at a lot of your content and it's great. I just bought an 08 a month ago... Sadly my experience hasn't been well... I'm having a no crank issue with my 2008 WRX, everything lights up but it just doesn't crank at all I don't hear a fuel prime nor do I hear relays or switches in my cabin when I put the key in attempt to start the car. The car was running fine prior to this... All I did was swap out coil two and four along with new plugs and put the battery back the car started up just fine. I was getting a P0304. She started up and ran for about 30 minutes with no issues. As I pulled away it's simply stopped running while my instruments and everything else was on at the end of my block. I turned the key.. Panel lights up but no crank at all. Everything has red 12.6 and I have not found a blown fuse yet. After several hours of testing I gave up and sent the car to the dealer. Subaru is the 1st car to ever defeat me. What do you think it could be? 2008 wrx 2.5L turbo 5 speed with 166xxx miles. Thanks

[@Smeedia]

From my experience with an issue like this it's bad battery, blown fuse, bad relay or a damaged harness. From what you've already checked I'd say something in the harness. Not a fun time 😕

[@g1g1ddy]

Hey Tanner! I’m building my 2012 wrx to be a fun DD street car. I have just about everything you’ve mentioned on this list except for a built block and gauges. I also have the killer b header and process west TMIC as well. I’m planning on going for a pro tune in the spring. Do you think I will need any fueling upgrades with this setup? Power is not my concern at all. Not really concerned on how much power I make. I just want to make sure it gets tuned properly. Reliability is my main concern.

[@Scattmann619]

Only thing I'd add is properly warming up the car (driving habits) and when you get a tune, get an electronic boost controller.

[@IFxSI]

+1 hell yes, I notice that even the newer ones (19Wrx for me) there is so much fluctuation in my boost readings. Gotta install my boost controller and get my retune asap.

[@didyaboi237]

Hey man loved the video! I have a 2018 and have been doing the oil changes at every 6k because it’s what my dealer recommended. Do they use oil that lasts longer? Lol or should I just change it at 3k from now on

[@Smeedia]

Subarus OE oil that they use is not the best. If your still within your warranty and want to retain it, I would continue to go by the dealers recommendations until your warranty is up if not I would suggest doing them every 3K miles though. I've always done 3K changes on all my subarus and never had a single issue with any of them. I wouldn't trust mine at 6k intervals

[@ThatWasherNerd]

I have a 2005 Legacy GT, which the previous owner modified heavily. I'm planning on investing in these mods to keep this thing reliable. I already have a tune, catless up-pipe, AVO top-mount intercooler, Stage 2 Clutch+flywheel, etc, but I want this thing to last a long time.

[@Smeedia]

[@Smeedia]

@@ThatWasherNerd Anytime! 😁

[@TheChemisch]

3k miles is a good rule of thumb if your car is semi-new and you don't beat on it. Better practice is to check your oil every time you fill up it's pretty easy to tell when your oil is getting worn out. If you happen to have a tunnel in your daily commute like me you might be looking closer to 1.5k-2k miles, check your oil not your odometer.

[@Smeedia]

Lol the tunnels get us everytime 🤣 but your right checking the oil when filling up is good practice to follow. Especially if your car consumes a good amount.

[@CousinBowling]

​@@Smeediawhy tunnels?

[@keithprinn6900]

I and my family have run numerous subarus for 20 years never had reliability issues when standard and even when modded went to 150000 kms until signs of engine wear. No issues with changing plugs at manufacturer recommended intervals and yes I put an aftermarket alloy radiator in my highly modded Forester XT after 6 years. I have a Perrin AOS on the modified Foz. Dump pipe and quality 3 inch TBE wakes the car up. I changed the oil pick up at 150000 to the Killer B set up and sump when the engine was swapped out. No issues but when dismantling original block saw the signs. Aftermarket air intake mods and blow off valves ? forget them total wank factor until you get highly modded.

[@apachelives]

High mileage EJ22 NA owner, i was getting hesitation and poor performance from the old girl - catch can helped (blow by / oil fumes = oil + fuel = lower octane = pinging = timing retarded = hesitation, also oily carbon deposits), also did a knock sensor mod (rubber between knock sensor and block to limit what it detects, moved it back near the transmission) - helped, finally did a knock sensor delete (resistors to ground, no knock sensor) to kill the hesitation (no pinging unless i run crap fuel) - my valves / piston slap / worn engine seems to trigger the knock sensor/ hesitation. Even the old 4EAT auto box shifts smoother (i have heard the transmissions can misbehave because of the ECU, can confirm). Don't do this until you have exhausted the usual suspects because usually hesitation is because of actual issues/faults causing the knocking and the ECU doing its job. Hopefully this might help someone out there, the knock sensors seem far too sensitive.

[@mike63ful]

I have a 16 STI, just do regular maintenance on it and make sure you monitor the oil level often and you should not have a problem. If you mod. it make sure you get it tuned ....

[@Smeedia]

Pretty much, regular maintenance goes far on these cars and is so often over looked for some reason.

[@Jfromes1]

Leave the car stock and follow the maintenance schedule set forth in the manual. In addition, don't thrash on the car till its warmed up. I think it also helps to keep the car clean inside and out.

Not fun to leave it stock though, you can modify them reliability

Everything else is still stock and i’m sitting at 44k miles. Does this sound reliable or kind of a disaster waiting to happen? I don’t drive my car hard really ever but I do live in Texas so every now and then there will be a pull or few on the highway? I’m just so nervous about these subies man.
