So cool Rally crew chief here: These engines have a real issue with a few things. PCV should be scavenged through a catch can via the exhaust as a venturi. The computer sees the PCV as fuel (O2 sensor) under boost and leans out accordingly and or pulls timing when it gets knock from becoming lean Cylinder 4 has poor cooling and can have predet because of this. There are fixes made by several companies The turbo inlet pipe should be replaced as it is prone to tearing and any post MAF leaks will cause headaches The knock sensor should be replaced and sprayed with a dielectric layer (they all crack and suffer from moister intrusion) Coil packs are important and have a shelf life of about 60k kilometers Oil pickup/baffling is an important for rally along with a skid plate reinforced under oil pan but actual tarmac racing will require a dry sump system. The up pipe, header flex pipe and flanges are all prone to leaking and should be replaced and flat faced. The TGV valves can be removed internally to avoid issues. The stock top mount intercooler should have heat shielding on the turbo side and a chimney set up to direct air from the hood scoop to the turbo to push hot air under the car. The rear of the hood should be spaced to allow excess hot air to escape when racing to avoid massive under hood temperatures. The rear differential outrigger arms need a "cushion" installed as a shim abover the outboard mounts to avoid clunking (truck mud flaps cut into circles work) So many more things important to racing but who knows what direction you guys are going with this. Good luck.
As rally codriver/driver as well as sf5 owner and mechanic by hobby, 100% on this... On other note often overlooked when using subaru in rally/motorsport application: TUNER! There is differences between dyno queen tuner chasing beautiful grapgh and big power... Then there is proper tuner knew how to make the engine last whole rally season...
@@AmirPomengreat note, I couldn't agree more. Not so much for performance as for longevity. Making it to the last stage is how a podium finish happens. We prefer road tunes vs dyno queen tunes. Better to have it work well in the condition you intend to use it rather than have bragging rights for telling your buddies at car shows and vape store parking lots
I have a renewed love for YT and it's thanks to you guys, keep doing what you are doing this is history in the making for the viewers in the future who decide "You know what, I can tackle that project" thanks to Davin and the team.
you guys should inspect the rear suspension top hat/strut top mounts and arches around there. in canada, those are very notorious for rusting out on an otherwise decent looking vehicle..
I realise that it must come as a big surprise but there are other engines other than a small block Chev. They are not weird, they are just not what you are used to seeing, and that makes them different, not weird. The Subaru boxer engine, in all it's variations, is incredibly successful and versatile. I hope you enjoy doing what ever you are going to do with it.
Fun to see Davin get into the Subaru! See it's not as hard as it look! It all comes apart as little sub-assemblies. That intake will come off with almost all the fuel, vacuum, and sensors as one unit. You'll be down to a long block in no time.
Never seen a Subaru motor pulled this way haha! They’re surprisingly easy to yank out from above, since the bell housing is in the middle of the engine bay and just about all the hoses and lines come off with the intake manifold. Can’t wait to see how weirded-out Davin gets once this thing’s apart lol
I believe Davin stated this car had 300k on it and I don't know how many Michigan winters, frankly I thought the undercarraige would mostly be a collection of air spaces held together by wishful thinking Coukd be worse, we've all seen it.
A few years ago I bought a beater '97 Outback to play with. It had multiple issues and was already mechanically totalled, but I got a good year and a half of fun out of it. I see the attraction. The top mechanical issues, BTW, were a dead clutch pack, weird noises from the transmission in reverse, and no service history on the head gaskets.
I love watching your rebuild projects, but this one is especially sweet. We have a non-WRX blob eye of similar vintage, and I've become a big fan of the marque since I've been driving it (girlfriend's car), so it's going to be quite cool watching you tear down that boxer engine and rebuild it.
Awesome, I am working on a Subaru Legacy right now. The original owner had the timing belt break. I am in the process right now of over-hauling a junk yard engine to put in it. Its an Arizona car and completely rust free.
Love watching your videos. I used to be able to rebuild straight 6’s and flathead V8’s (yes I’m old). Never tried a newer engine and not sure I could do it. You make it look so easy. Thanks for sharing.
This is easily my favorite body style of WRX in my favorite color! I'm not a fan of those wheels, at least in black, but I like the rest of it! It's a great starting point.
I loved this video, the Subaru Impreza WRX is amazin' and I love this car, I never saw how remove the engine, I hope watch the rebuild of this engine soon
Nice job , Gents! always looking for Hagerty content especially for beater wrx's..... i'll try to makes sure i give mine the beans at least once a drive...
what'sapp-line+ with Hagerty's Icon or whatever it's called. Smells fishy to me. Two other channels I watch have had issues with scammers pretending to be them. Could this be another example?
I've loved this channel (and the services of the parent company) as long as it has existed on YT; Davin and Tom are tops! That said, this particular project can be summed up for me with a simple phrase: "a LOT more fun to drive than to work on". Will I continue to watch Davin anyways? Of course! - Ed on the Ridge
Have you wrenched on a Subaru? They're actually very easy to work on. He did it a bit the hard way, but good enough being that the subframe is getting refurbished too presumably.
Careful with the machine work on the case halves if that needs to be done. They are really sensitive to shifting without proper torque plate setup and the bores and mainline can end up all over the place if done improperly.
So, what was the purpose of pulling the whole subframe assembly? Are you replacing it too? I only ask because I usually just yank it out from the top for rebuilds. I typically get it done in about an hour that way, but you seem to have bigger plans. I gotta say though, I'm really excited to see this channel take on a Subie. It definitely caught me by surprise. It's definitely out of the norm for you guys. I think the closest I've seen on this channel was the Beetle. That was also worth the watch. I can't wait to see the progress on this. Keep up the good work!!!
Yes, I saw all the rust, but he also said he broke a couple bolts he had no intention on replacing. So, now I'm confused because he'd only be snapping bolts from the subframe to the unibody. There's only two nuts holding the engine to the subframe and those usually come right out. And the way he beat on the car early on makes me think the rest of the car was going to scrap. Either way, his process was interesting to watch.
@@michaelmaas5544 that's what's confusing. That's an awful lot of work...just to pull the engine. Especially when they come out through the top hella easy. I saw he pulled the trans too, so, maybe they're restoring both. Idk. Just seems like more work than necessary and makes for entertainment.
Davin I will add to the Rock auto tip to dip the end of the fastener in a little oil before putting it back. Especially when dealing with rusty M 6's. Great use for that little bit of oil in the bottom of the oil bottle.
Fun fact, you can mostly rebuild a Subaru Boxer engine with just a 10,14 & 17mm wrench/socket. They are actually very simple to work on once you get past the wierdness. Really looking forward to this build!
Stage rallying is relatively popular in Michigan, but I can't in my wildest dreams imagine Hagerty spending the money to make this legal for competition. Maybe gravel TSD Rally car for events like POR? Both these type of events are run on backroads like those in the intro. Easiest/quickest would probably be rallyx.
Looking forward to this build. You guys should really consider putting the completed engine in a street-legal dune buggy/sand rail and lift the front tires leaving from every stoplight. It would definitely have the power.
If this is your first metric engine, have fun not losing your 10mm tools. Everybody who works on modern cars likes to joke that when they need a 10mm tool the most, they can't find it. You might be able to locate a beefy subframe made of welded chromoly steel. They make great replacements for the stock stamped steel ones cars come with. Since you need one new subframe anyway, that's not so bad.
My favorite part about putting the hardware back in the holes as you remove parts is getting a part almost all the way reinstalled before figuring out why it isn’t seating correctly, then realizing I forgot one bolt
I don't know how far ahead the project is, but Subaru fans love their cars. Popular mods are JDM engine swaps and STi conversions. Even a six speed manual transmission is considered an upgrade. And, yeah, the frame rails and body needs much needed attention.
That rusted “subframe” is actually a US spec piece for crash safety. They don’t sell it on them in the JDM market. If you don’t put one back on it’s a nice weight savings for the front end. Cheers.
Having made the exact same journey from classic American cars, go slightly less classic American cars, to funky, older imports and then eventually hitting subarus, this is gonna be a fun one for y'all.
The casual mention of how bad the car is makes me wonder what this engine is going to be going into when it's finished. Then the seemingly random shot of a Beetle in the back ground shot at one point. These engines are often used in Beck Spyders and similar low production cars. I'm curious where this engine will be put after it's finished. Can't wait to see the series. I've never seen a Subaru engine taken apart.
Clean it first for as someone use to say when I was in the military, "A clean shop is a happy shop and a happy shop is a clean shop." Plus who like having dirt in their eyes? Anyway from what I have heard Subaru's are built to last but I admit I have only owned one in my life and it was doing well until I went to Japan for a year as my cousins never moved it in LA and it got taken by the state and that was the last I ever herd of it.
As for the Red Annodized Pulley on the crank if it also has lightweight flywheel then its a very much worth it mod as the pulley is cheap and flywheel not so bad. But the Engine revs upto that 7,000 rpm almost half the time (or about 35-45% reduction in Wind out time depending on how light the flywheel is) Majorly improves Throttle response and drivability and also performance as the engine revs out much faster just doing this mod alone takes more than 1sec of 0-60mph times
Engine comes out the top mate. Not the bottom! Be sure to put a new turbo on it and some new headers - easy power gains and sounds way better - the OEM exhaust is crud and weighs a ton also. Have fun - your first JDM!
yall flew the hood off and damaged it on purpose :( fasniating professional engine work. cool to see how you will replace the rusted parts in the future
Yeah I would be to thrilled at working on modern stuff either but every days a school day My guess is it's going to be some sort of cross cart when done considering how the body was treated
So cool

Awesome seeing Subaru content on here and love Davin’s commentary 😂Boxer engines are so weird if you’ve never touched one before!
As a previous owner, I can't wait for this! I know what is coming and your educational reactions will be great as always.
Keep it up Davin.
I can’t wait till he gets to the wrist pins!
you guys should inspect the rear suspension top hat/strut top mounts and arches around there. in canada, those are very notorious for rusting out on an otherwise decent looking vehicle..
I don't think, I mean, I'm sure he won't put the engine back on this rusted POS.
Always look forward to the new projects on this channel.
The process of teardown and reassembly is so entertaining.
Thanks Hagerty
Awesome, I enjoy hearing the reactions of guys used to working on older stuff when they work on more modern/weird stuff like Subaru flat 4s

Love the good humor, and bravery to try something new. I love all things greasy and oily!
Awesome, I am working on a Subaru Legacy right now. The original owner had the timing belt break. I am in the process right now of over-hauling a junk yard engine to put in it. Its an Arizona car and completely rust free.
I like seeing someone who isn’t afraid of getting a little oil on their hands and drains oil without using rubber gloves. That always cracks me up.
That WRX was hot in it's days. Serious performer and quick !
Love watching your videos. I used to be able to rebuild straight 6’s and flathead V8’s (yes I’m old). Never tried a newer engine and not sure I could do it. You make it look so easy. Thanks for sharing.

Takes out on a dirt road and presumably thrashes on it a bit. Then says he wonders if it will hold together when he puts it on the lift.
what'sapp-line+ with Hagerty's Icon or whatever it's called. Smells fishy to me. Two other channels I watch have had issues with scammers pretending to be them. Could this be another example?
so so excited to see this teardown
That intro was just.... 10/10
Who’s idea was this anyway? I don’t have high hopes for this project but I did enjoy seeing that ‘assembly’ sitting on the table. Good luck!
Never dove into Subaru. My parents went from Toyota’s to Subaru. But WRX would be my choice. This will be interesting, thanks

He pointed out major rust on the subframe. Probably going to replace it would be my guess.
He showed in the beginning the subframe was so rusted he could put his hand inside it.

1:49 Jeep owners laughing at the little bit of dirt coming out of the Subaru bumper.
You work really fast!
That intro was the best lolz
Uhhh this looks promising! Keep going Davin ! Love Subbies
Wait and see you'll love that car when it's done. Cheers 🇨🇦

The bugeye wrx! Dont forget to change that head gasket! Those model years are notorious for head gasket failure
This was fun!
Great to see you working on something I can relate to, here in the UK (I hate MINIs so that didnt count) Anyway, Nice one!
Definitely see the love you have for that car! More than ever!!
More WRX here Love it

Great car and great project. The Subaru is really a good car with performance which many other car manufacturers wish to have.
no other manufacturer is jealous of subaru
@@jradish many years best 4x4 and rallye cars
Love it man, so relateable now. Love to see a Toyota
Maybe he could build an AE86 to drift.
Remember to keep track of your 10mm. You're going to need it a lot.
The hood flip was a nice touch. You are a glutton for punishment!! Good luck.
Just did my 3rd engine on my subaru forester. Very easy.
And that's why I'll never own a Subaru.
awesome content. this is a very hard build because I can't imagine what Davin is gonna do with it. dune buggy? in Michigan? ok, then snow plow? wtf?

Good thing the hood didn't come off on the interstate as it happened with me. It makes for alot of calamity

thats what i love about Subaru s no door frame
Something I can finally relate to
This is going to be fun! What vehicle is this going into? I hope not the one it came out of...

Davin should watch a couple of Subi Performance vids to get an idea of what's to come 😉
Lightweight pulley or timely oil changes and maintenance...
LET'S GET THAT SHINY PULLEY!
Engine comes out the top mate. Not the bottom! Be sure to put a new turbo on it and some new headers - easy power gains and sounds way better - the OEM exhaust is crud and weighs a ton also. Have fun - your first JDM!
yall flew the hood off and damaged it on purpose :( fasniating professional engine work. cool to see how you will replace the rusted parts in the future
I've heard of having your doors blown off but having your hood blown off is a new one to me.
Working under a rusty, dirty, sandy car with no eye protection! Genius!
Yeah I would be to thrilled at working on modern stuff either but every days a school day
My guess is it's going to be some sort of cross cart when done
considering how the body was treated
How does that thing not have a knock or knock on warm up that goes away at temp. Most to all I buy or find do even low mileage ones
Lol it's like making my dad pull my wrx engine. It is what it is haha
Thank you all. The bug eyes are my favorite.
I like the Copart portion. Too many cars that need to be saved are salvaged and left for dead
If the fr subframe is that bad the inner rear strut towers are probably a distant memory unfortunately
Nice...👊🏻...
Hey man were do send your gauges to get refurbished
Good Old Faithful Sun Machine in the background
Probably dont need to tell yall this, but make sure you use a torque plate when boring the cylinders!!
YES!!
What happened to the beetle in the back? Is it broken? I ask because you have that done that motor a few episodes ago.
