Subaru Engine Swap Must Have Parts! 

More old Subaru content please. There is a lot of us.

I am shocked MotoIQ doesn’t have more of a following. These Subaru videos are some of the most helpful and informative videos on RU-vid!

Subaru needs to hire this man and remake their engines. Imagine all that he spoke of STOCK!!! and straight from the factory, Beautiful.

Mike I emailed you like 20 years ago about what spring rates to run on my B15 sentra. You didn't reply until a year or so later and I've always felt so honoured by that. Keep up the content I love listening to you talk about car stuff. Your modest but laughing its fun to watch

I can tell you love your trade. You say everything with a smile. Keep these videos coming please! Currently building my IAG motor and these help a ton! 🙏

Wrx /sti are a treasure people are catching on to these cars !!! These cars will be wanted like the skyline in the future get one before these cars go parabolic in prices

Great video, Subaru motors are crazy money

these types of videos are very interesting to watch! love it!

Great video guys and thankful for those that sent you guys our way!

Just when you think your build is over. ...It's never over. :D

Great video, it's really comforting to know that I managed my subaru's engine build to this level of precision. I'm an aircraft mechanic so I get very picky about replacing components even when no wear is visible for sake of overall longevity and efficiency. I also enjoy the format of these videos and the delivery method, there's no fake over the top energy, just a guy giving some honest info. Keep it up, subscribed.

I've been dealing with Subarus for 7 years and still I was able to learn something here. The chilled way of spreading knowledge is just great!

In other words if you're broke avoid Subaru

Good work guys. Keep it up. When I get my funds together you're gonna be the guys to build it for me..

I would love to hear what type of problems people with older subarus who thought they did everything right ran into at the track. MotoIQ certainly covers 99% in this video.

I love these videos. I would love to turbo my brz so hopefully y’all can help me get set up right

I went the overbuilt route for my WRX built too, LOOOOTS of IAG goodies on my car, the AOS, TGV Deletes, Fuel System, and the like, and cant forget the IAG Stage 2.5 block, they do an amazing job with their closed deck conversions. For the under armor, I prefer the TBW under body tray, but that one is just as good too, anyone with a subaru should get some sort of metal underbody tray.

excellent in depth explanation on going the next level. I'm good where I'm at with stock with spt add ons.if I was younger and had the cash would ship to your shop. God bless from hamden,ct

Amazing video once again. Love you Mike! Please post more Subaru related videos in the future as well

“But we’re old and grumpy” lmaooooo

Step 1: Throw Subie Engine Away Step 2: Buy Honda Engine Step 3: EJ Conversion Plate Step 4: Enjoy Superior 4cyl

Totally thought Mike said, “Slippery Nipple” at 4:37 😂

Love this guy!

great content from a very knowledgeable source. how about this one; why do some aftermarket downpipe manufacturers put the high flow cat at the end of dp vs some put them right off the turbo? any reason why?

A sect. 80 engine swap guide would go hard

I must say thank you for bringing the xclutch sprung organic twin disk up on my radar. I installed one on my longrod 257 build with an fp blue. Got about 1500 miles on the new longblock and clutch. Made 404awhp @20 psi on 93octane. Would be really cool if you could do a video on cobb FlexFuel alternatives besides open source and Haltech.

I've owned quite a few Subarus and currently on a built STI Hatch and these videos still blow me away, good stuff!!!!

16:25 I liked the video as soon as i heard him say Bittch! Lmao 🤣 😅 But i have an 09 Wrx that could use some newer parts

tgb deletes can be done with factory parts. my 06 non-turbo legacy wagon has them, and they are 30-50 bucks at times from ebay, or 5-10 bucks each side at a pickNpull

Great Subaru content. Made me rethink my engine power plans. It's just so $$$! Crying 😭

Wish I would’ve went with iag, outfront blocks don’t have clearances meant for engines that will last. After spending my life savings on a brand new fully built ej spun a rod bearing. Sadly I’ll have to wait another lifetime to save up to fix it.

:SLIPPERY NICKEL!? Isn't that a fancy liquor shot?

So in depth makes me question what I’m getting into ahahhaha

I'm running the IAG stage 2 tuff block, milder heads, Blouch 440xt, and Tomei Poncam cams. Other than that my build list was pretty much the same. Four years of hot Florida summers plus several track days and the car still runs as strong as it did on day 1. That iWire kit is pretty sick and worth every penny. It's a shame they can't keep them in stock. I've been trying to get ahold of one since February. I don't feel too hot about 120f fuel temps in bumper to bumper traffic.

class is in session! love the older subies too :D

I want to fully build my 2000 Impreza outback to 400 whp with STI power train. That’s why I play the lottery😂 keeping my fingers crossed 🤞

I have an 04 wagon had ringland fail spent 4k and it was a shady place and had it so called “rebuilt” never ran right but made it a year and all 4 rod bearings failed both heads are no good along with a bunch other stuff. Now my question is does it seem average to be quoted $13,195 for rebuild? They said they have extra heads ready to go at the shop already. This is a legit shop by the way but it really seems like I could possibly find a somewhat nice sti for that price and I have no way to get my car right now they have already billed me 4k just for the labor I’m not sure what to do. I just want my car to run right and solid and reliable. Thanks in advance and this channel is the best thank you so much for being real when it comes to prices I soak up most of the knowledge this guy gives out besides being able to pay for my wagon

just came across this channel and by far this is the best content i've seen for this topic. i have over 8 years experience being an auto technician and i like how you explain each part and why its an upgrade. also i drive a 2012 STi so of course im gonna watch all the subaru videos lol

There goes Scottie Ks gorgeous former 76 SR-5 again. 😍 Had one when I was in the Military . What great car. Keep the nice videos coming 👍👍👍

Hi hola yo tengo un 2005 Subaru impreza no turbo creo la bomba del aceite se arruino es mi primera vez en mi vida tengo un Subaru

Great video! You have a wonderful style for communicating technical info. With an easy-to-listen-to nonchalance. It is obvious why you narrate. Very cool man, from another grumpy old man.

For all the guys looking to save a couple bucks on their build I highly suggest going the extra mile on the block and maybe save a few bucks elsewhere by picking up used parts in instances where the part isn't prone to mechanical failure, like downpipe, TGV, intake tube, ect. Had my block done by a reputable shop but decided to cheap out on the closed deck option because they rated the open deck at 400hp and that was right around what I expected to put down. When all was said and done I ended up at 450hp and about 7.5k miles later one of the rods ended up snapping in the middle and went right through the block, next to the turbo. Well, a lot of oil flies out of a fist size hole in an engine block and it started a fire. It would have been a true disaster if I wasn't on my way to a BBQ with a big cooler full of ice/water/beer in the trunk but there was enough in the cooler to put it out.😂

I like this guy in the way he explains everything is so awesome. But he's a expert.. I wish he can work on my Corolla GR.

Like how he says “…tell us what you want. Write us a kind of INTELLIGENT description, and we’ll get back to you.” 😅✌️

Super informative! Great vid guys!

Aah love this guy 😂aah!!!

Best builder hands down

I love these videos so much, the super chill delivery of facts is so good. I can't find the article now but I remember reading about a lossless exhaust that was developed, I think it was on a corvette. They used all kinds of trickery with the pipes to keep the horsepower the same between open headers and full quiet exhaust withs cats. People don't understand there is actual science behind this and "butt dyno" usually lies (mostly in the form of the loudness went up disproportionally to the acceleration).

Haha write an intelligent description. "I Dun want my car make more power" awesome video.

I am looking at an IAG 750 on an EJ257 from an O7' STi. The short block is reasonable at $5K. I am planning about 450 to 475 WHP on 1050cc injectors. Probably drop NEW radiator, alternator, oil cooler, IAG oil 11mm pump, IAG oil pan that carries an extra quart of oil, with a cylinder 4 cooling kit, 1050cc injectors, and maybe a new fuel rail system for top feed injectors and the I-wire fuel pump rewire kit. So for maybe 475 WHP... it should be OK on stock head. The question is: Should I just sell my stock STi long block for maybe $4K and drop the IAG 750 LONG BLOCK in its place????? WITH ALL THAT, I would like to use my stock head if it isn't an issue. Thoughts?

The parts on that table cost more than the car. I'm seriously considering selling my Subaru just because of how expensive it is to make good power

That is a lot of great information shared. Thanks for putting this together. It's very useful for those of us who don't live it every day.

Seems like IAG has a product to improve the EJ in everywhere. Great video!

I appreciate you sharing all this knowledge. you are like the Subaru Sage.

Were you making 400whp on pump or E85 with the Precision turbo?

Mike seems like the chillest guy ever. All he needs is a blunt and I'll smoke it with him and listen to him talk about cars while we fixing one

I don’t have the type money to put in my car- looking at at least $20,000 - My motor for free ( haha 😂) jaja ❤

i Smashed that like button! shared and commented for the algorithm !

SUBARU ENGINES ARE FACTORY JUNK AND THEY SHOULD BE AVOIDED IF POSSIBLE!!!!

Mike: take it to the next level. Vegeta: ITS OVER 9000!!!!!!

Just what your gunna do is.. dump almost every dollar you make into this and maybe it wont break but until then *ssssttuuuuu* really nice

This guy could be feeding me complete bullshit and I would still trust him and his smile.

This man is high af

great vdieo 100 percent. you guys should think about doing a gc8 4 door build!!!!

Timing chain on an S4 Audi dosen't seem so expensive or complex now.

Mike I hope to see you at the Pikes Peak Hill Climb Race!

I would love it if you would do a video on the new impreza 2.0 & 2.5Lt. It has 2 or 3 major issues, one being the " advanced " Thermostat. Basically how to turn this model into as much as possible trouble free machine. eg. proper maintenance of CVT. Sorry did I just type a 3 letter swear word?!!🫡

No superdamper? Fluiddamper is the shiz and a must on any baller motor.

Let's see an AMS manifold on this project no tgv deletes needed.

Really helpful!!! The EJ motors have come a long way.

the next level $$$$$$ too much denero for me. 70 on a fixed budget,

Can't wait for you guys to rip into those FA24 turbo engine and give em the sauce 💪

So, is this thing running yet? Where's the big reveal party?

I would also like to advise since the oem alternator can’t handle the power output needed, the DC power performance alternator does wonders to all electrical parts needing that great supply of power. The oem alternator causes that subaru “dip” that everyone noticed during idling or at the traffic light. This aftermarket alternator fixes that issue because it supplies the car with better power output than the oem one. Mike I’m sure you can look into DC power performance alternators and explain it way better than me haha.

Amazing how much stuff needs to be done to a Subaru 😅

I always come back to your videos, no matter how old. The ej20 would you ever recommend a build using that block and valve train for a daily around the same bhp that you recommend on the ej25 of 500bhp

@MotoIQ Do you guys have and engine build kit for the OBS Impreza's? I have a 97 wagon I'm tearing down (rebuilding transmission ATM), and I'm look for around 350WHP replacement engine. Knowing what must be done to build a truly "Bullet Proof" engine I'd like to outsource for a short block and heads. Got anything like this?

Mike, what software/hardware will you use to tune it? I know Cobb is not an option with the TGV deletes and speed density. Thanks

Looks like you're missing the speed controller in that kit. The black part you held up is the relay block. A common upgrade for the controller is the GTR controller. They're plug and play. This must be an old video, "TGV Deletes" is a dirty thing to say these days.

Wonder if the WCP treatment to the engine components would benefit or last thru the years... sounds good tho

Just bought my first STI SUBIE some months ago, had to have the wing model, they have always had my attention N owning one, its blast to drive!! put in the invidia exhaust, sounds bad ass distinct subie sound and did the cooling N oiling upgrade N ts been a dream!!! FYI SUBD!!!

One day...... ill get a fully built motor for mine

LETSSS GOOOOOOOOO!!!!! @4:43 that's what she said 😏😝

Doesn’t setting up parallel fuel rails also help pre-detonation in cylinder four? The path the fuel takes from the tank being routed oem goes in a loop not directly to four being the last to get fuel so the lack there of can cause pre-detonation hence knock.

always here for the subie content

you may know. i have a 2002 outback with a 2.5 flat 4. i have another 2.5 from a 2007 suby. can the 2002 parts work on the 2007 engine????????????????????????

Can someone pls tell me the best engine to switch with a 2018 BRZ unlimited budget

FYI... IAG 900 is $12,749.99 You're welcome.

Bonjour, votre chaîne est vraiment géniale car vous faites cela de manière bienveillante. Vous parliez de ce "subaru Idiot"(mon interprétation) que pensez vous des collecteurs d'admission Spec C ? Ils viennent directement sur les culasses, les tubulures sont plus longues car plus de TGV et les injecteurs viennent se monter dans les portées de joints au niveau de la culasse. Salutations de France 👋🏻

how do you address the rod bearing failures? best remedy to prevent this and drive hard

Your mic is picking up this nasty neck sound

@Hagerty This is how to build an EJ. Yeah, you probably did it cheaper, but this will last a lot longer.

You mentioned "tgv deletes" and "flex fuel"... What's the plan with the Cobb Access Port not supporting that hardware anymore? Is the accesstuner software jailbroken yet, the "green speed" update was just a month ago. Super interested in your plans here.

All this talk about LS motor swaps etc. How does one do this and keep awd? Cost?

Amazing video but what’s up with all the Velcro noise

Was just looking at the guys from gears and gasoline which lead me to here. Those engines appear to be terrible from looking at you and them.

When talking about the MAF and air speed density, is it a swap, or all the parts mentioned make it air speed density? Also, where can I find those parts because my engine is getting bogged down from my cold-air intake, and the stock MAF does not like the intake at all lol. I sometimes have to give between 75%-85% throttle when up shifting to keep the rpms at a higher point. It's almost like there's toomuch air and it's choking the engine if I push the throttle to 100%.

IAG uses only 2816 forged pistons as opposed to 4032. Should this be a concern for me since I'm looking to daily it in the winter?

Woowwww Dominic doesn't even get his credit for his product

Question with the newer subaru 2.2l fit a 1995 legacy automatic transmission ???
