Ha, my last car with a Legacy GT with the EJ255 (2.5 turbo, same short block / heads / valvetrain as STI, just different turbo). Honestly I think the 2.5's were a step back from the 2.0s. This also looks like an insane amount of money and work just to hit 400-500hp when other manufacturers can get there stock (any chevy/ford engine, especially the LS), or more reliably, like the Honda K series with a turbo. I just wish Honda made better RWD/AWD options to pair.
I think he's smiling because he's literally explaining probably 20 plus years of experience and all the expertise and knowledge he's acquired that its literally a joy to pass on the knowledge. It's like a teacher that actually enjoyed the subject they taught, all of us has had atleast 1.
this is not subaru stuff" specfically this is performance car stuff which transcends makes and model, all the principles he talks about apply to any engine, mean loading, engine speed, ve, etc 90% of what he mentions are things that applied to my non subaru engine build.
Mike is basically a walking automotive-related encyclopedia. Another great advice to add is having a great tune and always addressing any issues that the car has, immediately!!
Improve the pcv setup and do everything you absolutely can to prevent oil blowby getting oil in the cylinders and causing detonation. With such a short small crankcase the pcv for the case is right by the crank which is spinning oil all over and oil vapor and it sucks the oil mist right up and either cakes up in the pcv or sucks into the intake and into the cylinders ruining the cats as well as causing damage under boost, caking up on valves etc. Boosted, even worse blowby forcing it right up the pcv
That's a double edged sword though, I mean you really don't know where you stand till the moment you see him give you a hand,...your hand... , with that delightful smile of his(damn he's got a great smile). He could tell you go to hell and you would look forward to the journey... damnit it's too late for me...save yourselves you fools I will now be doomed to watching and liking every video on this channel......*** Voice is drowned off by UA-cam advert without next botton*** (seriously I'm enjoying this)
As someone who studied automotive engineering, and who has taken material science classes along the way, I absolutely love the technical detail he mentions in this video.
@@Yo-mv6py Hey I am also an Automotive engineer and there are many careers to go into. You can work for big companies like Ford, GM, or Toyota. Also, you can work for Cummins, Peterbilt, bobcat and so much more. There are tons of options in a field with very few people qualified.
Mike, I've spent years building engines and it took that long to dig around and build up the core knowledge you outline in this video. This is without a doubt the most comprehensive and concise run down of building and modification details I've ever seen. Obviously there is some esoteric detail that is Subaru specific but from beehive springs to rod ratio to hone plates to valve shape and porting. This stuff applies to really any performance engine build. Thanks so much for this, man. I'd encourage anyone interested in engine building to go through this outline and dig deeper into each section Mike has covered here. There are ways to do some of what he's outlining in this engine build that are not as expensive. CNC porting is the best but even a little care and skill with a die grinder will yield good results. Blending the valve seats, getting the block prepped well, deburring, matching the water jacket ports with the head, finding the best parts you can afford and parts that work well together. What the running characteristics are that don't translate to dyno numbers but do offer a better, smoother performance. Good stuff.
I love how indepth you go into the how and why of the build, instead of just slappin on parts. Makes me wish I learned more during FSAE before i graduated
I’m addicted to this guy. He’s so smart and genuine. Reminds me of my grandpa and his car shop. Super awesome I’m glad I have the opportunity to watch and learn from these videos
I'm supposed to be writing a report for my Master's project that's due day after tomorrow, and here I am watching full videos on how to build my favourite engine ever. No regrets.
I've never head anyone who sounds so stoned manage to successfully explain a complex topic so well. Great explainations and information. Thank you for sharing. PS I'd love to see a EZ30R build.
imagine having an internship in this garage🤯what a guy he is basically a walking encyclopedia...what a great video with detailed description and explanation...you are awesome👌
I remember Mike Kojima from the Sport Compact Car days. Always a passionate fountain of information! Cheerful explanation of knowledge way beyond what mortals can comprehend. He’s a national hero! If he builds something, it’s the bees knees
I was waiting for this guy to start laughing the entire video. He's so happy about what he does. His knowledge is next level. Youd sleep easy thrashing an engine built by this man.
I don't even own a Subaru never have but I have been looking at the new WRX and the UA-cam algorithm brought me to this video. Even though I don't have any plans of doing any mods I still found this video so entertaining and relaxing love how he smiles throughout the whole video.
I agree the KillerB oil pan, baffle topper and pickup are a worthwhile investment for the Ejs. I actually never knew there was a option besides the harmonic balancer. That's pretty cool! Great video. I'm hoping you guys do follow up videos on the building and final numbers.
Great video. He really knows what he's talking about and explains how all the parts he choose help improve reliability and power. Hopefully there's one about the 4G63 soon!
Finally, a video that doesn’t start off with some guy yelling at the camera. This video is so refreshing with his sensible presentation approach. Thank you! 🤙
It's good to listen to a master of his craft who can explain things they've learned over a lifetime of experience in a way that sounds as simple as "water is wet".
I'm telling ya coming from a owner of a 02 wrx with a ej205 built with a stroker kit hands down love it. 92.5mm pistons and Manley rods h beam. Sti crank heat treat,td05 20g turbo,750cc inj,fmic ...etc,etc. 400whp daily driver 30k miles no problems.
@@nathansmith9812 prob another 45k till I change the timing belt again it's all in how you drive and maintain plus I built it right. Doesn't even burn oil at all just saying.
This is fantastic info. I’ve had an EJ257 that was a bit of a test bed when it was put together about 10 years ago and has been subjected to lots of circuit (road course) use as well as street use. I stuck with stock stroke but used long rods with custom short CP ceramic coated pistons. I’m also running Kelford cams/retainers/springs with high lift 264 cams. I’m using Possum Bourne Motorsport 14mm head studs/TGV deletes. Some things used here are a bit different (probably better here if I’m honest) but I’m cheering about the similarities between this one and my slightly oddball build back then. Excellent content and presentation!
This is at least a 20k motor build with all those treatments, cnc’ing, precision parts and that’s without labor.... I’ve watched it twice now, and enjoyed it a ton.
This Guy is the best, he knows everything about these engines... You can tell this is his passion, and he's happy as a clam to have this engine. I am a Diehard fan of Subaru's too man, Cheers Sir.
Those are great cams for a EJ25 Hybrid or EJ25 with AVCS removed as well. I used them on the latter with e85 and a TD series turbo. I hit 27psi at about 3.8k and it held almost to redline. Because it was easy to keep the car above 3.5k lag was non-existent. But I went with forged internals without any other shortblock strengthening so I ended up with a hole in the block large enough I could grab the crank with the engine still under the hood, haha.
Normal people will never understand this. On the couch at night, watching him smile and talk about all this technical stuff…..something about it is so mesmerizing
The costs are covered in followup vid. Ya the coating/surfacing services aren't inexpensive. Noted: the big thing on this motor is the use of 'torque plates' to duplicate assembled distortion during machining ops. For better power , longer engine survival.
@@peted5217 who use's this exact process when they machine the cylinders? IAG? Anyone you know of? I want to have my RA block honed and maybe bored a bit.
My 2015 STI non ra block lasted 33k 1.5 years. Turbo upgrade and everything. I drove that car so hard lol. Now I’m getting a built engine from metro performance.
Mike Kojima, I have been aware of you since BEHINDTHESMOKE youtube show, where you managed the S13 of Daijiro Yoshihara. You are always so positive and kind. Thank you for the shared knowledge. I listen to this as I fall asleep.
And seeing it actually running and working how they hoped. Not that I doubt it, I just would love to hear this thing and see what it finally put out power-wise.
That right there is passion on his face. So refreshing to see someone who is just happy to talk about and give in depth explanations about something he clearly enjoys. I think we've all gotten so used to negativity that seeing something like this is truly special
Remember the good ole days when we ran extrude honed b series intake manifolds and they kicked all the asses? Well, these oil gallies need that love! Soo many rough and sharp edges, all working against the surface tension of the oil and adding heat and friction!
I find it so soothing to watch Mike smiling whilst talking about how to build a durable ej motor. Just sitting in my wrx in front of my workshop just watching this vid
I like the way this guy presents himself. I bet he's a decent guy to sit down at a picnic table with while eating steak and macaroni salad with while just talking about life in general.
Im going to have to watch this a few times in order to truly understand everything he talks about. Now i have a glimmer of what im missing as I replace the head gaskets on my 96 outback.
Makes me want to rework my wife's 2.5, and that's saying something. I like the fact that he seems very happy about talking details that he not only knows a lot about, but obviously he loves his work. Fun! Insightful!
I wish you would have just stuck with the 2.0. I made more peak torque with my 207 than my tuners 257 with both of us with nearly identical builds, same turbo and boost levels. I just had an extra 1k RPM I was happy to play with. Love me that rod ratio and better oiling ;)
That’s only because you were closer to volumetric efficiency. If you were to run at the same fuel volume and air volume when the 257 gets to its efficiency you’d be out of efficiency.
Wish I found this channel earlier , love it, doesn’t brush passed tips, and gives enough info to know what questions to ask or research for further under
Do I have an EJ engine? No
Do I plan on building an EJ? No
Did I enjoy watching the whole video? Yes
I agree, pretty much every company makes a 2/2.2/2.4/2.5 liter engine that this applies to though
In my instance it was Yes/Yes/Yes.
1. Yes x2
2. Yes x1
3. Yes x10
I have an EJ205 with 7k miles on the rebuild feels good lol

dude just casually dropping MOUNTAINS of knowledge. respect
imagine Mike telling you, your motor blew up with a smile then goes on to explain for 45mins how he's going to rebuild it
That's my dream 😂😂😂😂
So basically every Subaru owner watching this video?
After that the customer says I changed my mind bye

I can’t even be mad at him regardless. I’ll be like, okay take my money 😅
My Sti engine blew up and I am happy because Mike has that mischievous smile

As an owner of multiple subarus and having rebuilt a few motors, this was the most informative, no bs ej video I've ever seen 👏
Ditto!
yup, gave me all the info i needed about rebuilding my shortblock
you'd think you'd learn and buy something reliable lol
Do you need any special tools to get the job done ?
it's refreshing ain't it and so easy to understand
So refreshing to hear someone who understands what he's talking about, explain things so clearly.
That's THE Mike Kojima for ya. A LEGEND in the community.
This guy is a straight up genius. I've never heard someone put so much detail and care into a block build. Kudos
I loved every second of this almost 46min video, even not being a Subaru guy
not a subaru guy at all but would watch twice
Yes the same i don't own a suburu and I enjoyed the video
Im a subaru guy and as such am honor bound to encourage you to become a subaru guy.
this is not subaru stuff" specfically this is performance car stuff which transcends makes and model, all the principles he talks about apply to any engine, mean loading, engine speed, ve, etc 90% of what he mentions are things that applied to my non subaru engine build.
@@canton7180 totally agree
Mike is basically a walking automotive-related encyclopedia. Another great advice to add is having a great tune and always addressing any issues that the car has, immediately!!
Improve the pcv setup and do everything you absolutely can to prevent oil blowby getting oil in the cylinders and causing detonation.
With such a short small crankcase the pcv for the case is right by the crank which is spinning oil all over and oil vapor and it sucks the oil mist right up and either cakes up in the pcv or sucks into the intake and into the cylinders ruining the cats as well as causing damage under boost, caking up on valves etc.
Boosted, even worse blowby forcing it right up the pcv
He must be the easiest person to deliver bad news to.
He always looks like he's about to crack up after hearing the funniest joke.
That's a double edged sword though,
