Best Headgasket Upgrade for your Subaru | EJ25 l EJ20 ! Subi-Performance 

After a day of dealing with inefficient people, I watch one of your videos and I am instantly aware of your professionalism and skill, it is a pleasure to watch you work, greetings from Canada

I learned how to properly install my ej25 engine main and rod bearings by watching one of your videos...2000 miles on the motor and running strong!

Keep up the Good work! You English is excellent, never worry about mispronouncing a few words.

Well, I never thought I'd see my beloved Subi EJs being meticulously built by German guys, but damn your attention to detail is next level. Subscribed.

Fire rings (copper) are becoming standard for higher horsepower builds in the states. Nice work guys!!

This is what we love seeing all the technical side to this top vids thks

Love the work you are doing and the cleanliness of your shop.

Mate you are unreal! Insane to watch someone so skilled at what they do work. ..Also huge love for dashhounds 🐕🌭😅

Informative and technical upgrade. Great Job on perfection work.

Amazing work, greetings from the UK. We love you here!

Your copper wire reminds me of a similar process we used in a 1000cc hillman imp engine which were called Wills rings. They are complete hollow ring which was filled with a gas at pressure. They were inletted into the cylinder head around each of the combustion chambers with less than half proud. They sealed the combustion side of the engine but a gasket was used for the oil and water. I enjoy watching your meticulous builds and strip downs on a quite complicated engine ( compared to our hillman imps anyway )

The copper wire mod is awesome. I would have never thought of that. Gut sheiß

Magnificent, bro

Kann kommt von Können.. Also nicht nur Kaffee machen.. Aber sich den Kaffee verdienen! Ich finde es immer wieder beeindruckend, wie man solch Wissen, was über Jahre angesammelt werden müsste, selbstverständlich teilt. Da kann man nur den Hut ziehen.. Danke

Love your shop!!!!!!

Love your videos. Great work and nice tools.

The fire rings! 👌🏼👌🏼🤪🤙🏼

Very interesting channel. Accidentally went and not accidentally remained. I love Subaru.Thank you very much for your work.

We used to hand make head gaskets out of sheet copper on racing snowmobiles because they wouldnt blow out at higher compressions. We also shaved the heads to increase head compression. When doing that, we also installed billet piston rods. It was nothing to bust a crank at the PTO however. Nothing like watching the primary clutch blow through the engine cowling! Those were the days!

Good job guys. From California.

Well done! What a shop!!

Chamfered = angles. Beautiful work 😎

Master. Love it. More, send it! : )

This was an awesome tech vid. Always wanted to see O-Ringing and how its done

You're awesome man I have a 15 sti and you make me want to do so much to it lol

I can only wish I had enough money to have an engine built by you sent to Canada lol

Nice to see the dog!

Top Video Andy, grüße

science man, I like it!

awesome by far my fav channel but of course i have wrx s so professional

Nice upgrade

i am trying to find a head gasket for my ej20x, love your video

Russisch. Wie schön das klingt. Ich möchte Urlaub machen in dem Gebiet Nischnij Nowgorod.👍🏻

I only use Subaru oem MLS gaskets. The gaskets used on the XT. Thanks nice work.

Hi Andi, Ich denke einige haben das bei Phil und Björn gesehen und möchten das am Subi auch haben. Das Bohrwerk-Planmaschine flasht mich immer wieder. Einfach geil das Ding.

Very good Job.

Much respect very beautiful work good high-quality could you tell me about the white tables that you have the engine on what is that wood or is it some type of plastic

Great video :) Could you please tell me the type of cutter for the o-ring groove? Is the cross section / side view of the groove like a round U shape, or a V shape, or a square I_I shape?

Your replys to other people's comments and how genuine you seem is why I subscribed. Quick question what gaskets do you use on the ej25?

Super! Blatt !!!

Chamfer the corner. Hand wheel on side is called jog handle or just handle

the word for it is a chamfer at 3:22

Great man

Nice work and nice dog!👍😂

I've never seen that trick with the copper wire, is there any benefit using a larger diameter piece? Thanks, awesome video

Bro you're amazing

What brand head gasket do y’all use? I’ve read a lot about the OE ones being preferred, what are your thoughts?

The groove, and copper ring, is commonly referred to as an O-Ringed block. Very common mod done to forced induction (and in some cases) naturally aspirated performance engines (Gas and Diesel).

Как же приятно слышать русскую речь на канале немецкого Мастера!!! Так держать парни. Не то что 9 45 го))).

Just finished a head gasket job with exhaust valve guide replacement on 07 impreza 2.5L SOHC I-AVLS heads. Wishing I could do work as perfect as yours. Do you prefer certain head gaskets or does the horsepower level determine what to use?

Do you ship to the US? ..every video I'm impressed at your level of detail..keep up the great work

good job and more professional.

Idk much about the machines but I know you can install loaded pistons by hand one ring at a time without a compression tool save you the machine work. Save some quench pad. Though your angle could aide in some low valve lift flow improvements.

What's the correct head gasket size for my 2004 wrx ?

Great work now have a Beer!

О на русском !! ЗБС ! Продолжайте в том же духе =))))

What ej25 head gaskets do you recommend using on a nonturbo forester, im in between on brands or oem right now thanks in advance

Which head gasket is the best for a ej20

I like the mahle brand , I'll be using a set of pistons for my e30 S50B30 euro build

Замечательно!

Would it be better to place the ends of the copper wire at a bolt hole to increase the clamping load on that section of the wire instead of in the middle of the bolts where the clamping load is least?

Да на русском пацаны прикольно что стали делать Респект!!!В русских авто сервисах мало где так идеально чисто как у вас!

Whats the best head gasket? oem? Can the heads be oringed.. Great job!!!!!! thx

The copper ring would be a great upgrade even for the non turbo sohc ejs

Brilliant modification to cyclinder head ..so many ef25 here in the states had head failure due to the design flaw...btw it's pronounced Kop purr..

Is the 2012-2017 STI afected by this problem?I mean head gasket The engine of this Impreza is the EJ257

Привет. Расскажи пожалуйста какую ты делаешь глубину паза под медную проволоку, насколько она должна выступать над плоскостью блока и как при сборке ты затягиваешь головки на таком блоке. Ask Alex to translate my text, thank you in advance, respectfully Alexander.

спасибо вам за интересные материалы) продолжайте в том же духе) еще бы субтитры на русском были, для более простого понимания)))

Buena máquina y mejor trabajador. Lo importante es saber manejar las herramientas. "No es cuestión de tener la guitarra sino saberla tocar". Un abrazo Andy saludos desde España tu amigo José Antonio Gálvez Galán. unos mimos para PINA.

Hey Ich hab da mal ne Frage: Können Sie einen Kostenvoranschlag für einen EJ20 stellen? Noch habe Ich zwar kein Bedürfnis für einen neuen Motor, jedoch spiele ich mit dem Gedanken einen solchen Motor mit Turboaufladung in einem Polo 9n3 Projekt als Umbau zu realisieren. Soll nicht für die Rennstrecke spezifisch ausgelegt sein (sprich nicht max.Performance) sondern eher als spaßiges Alltagsfahrzeug, jedoch schon einiges an Bums unterm Arsch haben (so in Richtung ~250-350PS maximal). Oder empfehlen sie für den Angegebenen Leistungsbereich eher eine Stock-Engine mit Lader, Ladeluftkühlung etc? Grüße aus'm Münsterland.

Привет из Кургана)

Copper pronounced Ca-per you're saying Copper like the BMW Mini Cooper which makes me just giggle. Great video and love the cleanliness of your shop.

Is it possible to do the copper wire ring on a ej257 with closed deck inserts or would that be redundant?

Wie lange dauert Est wann ich mein EJ20 bei ihnen lasst reviseren?

Thanks a lot for the info, I don't think I seen this in the U.S.A. we can get closed deck blocks from IAG.

3:03 It's MPG handwheel :)

Hi what are you doing on 3.22 its called "cylinder bore taper" and should be min.0,015mm limit no more than 0.050mm

Amazing work, greetings from France! What about the FA20!?

Круто, хотя бы русские субтитры добавляйте. В России вас тоже смотрят

What would you say be the best thing to get 300-350awhp safely and reliably for an everyday driver?

In English the angle is called a beveled edge or bevel.

The EJ 257 STI engine is a semi-closed deck , not an open ;-) But awesome job ;-)

How much it cost a closed deck EJ25 from you? Or if I already have one, filling it up?

Nunca había visto algo como eso. Me refiero a lo del alambre.

Подскажите пожалуйста, на J253 началась проблема с проверкой уровня масла, один день на утро после стоянки щуп сухой, хотя знаю что уровень есть, на второй день уровень полный. Место проверки уровня одно и тоже, время аналогично, пробег дневной одинаковый, просто по какой то причине масло не стекает в поддон. Спасибо!

Its called O-ringing the Block ;) i always thought it cant be done on our engines

Всё здорово, но я не понял, как стыкуются концы медной проволоки чтобы не было зазора??

Dobry patent

WHEN YOU MOVING TO THE NEW SHOP. WANT TO COME SEE ABOUT MY CAR BUILD.

Ihre Meinung, welches Material für den Motorblock ist besser? Gusseisen oder Aluminium?

Какой должен быть зазор у поршневых колец?

Подскажите пожалуйста. 257 блок.Все в стоке. Проехал 20.000 Масло motul5w40 мотор не перегревался прямо уверен. Появляется задири!!! Смотрел камерой. Какой сделать зазор для оригинального поршня чтоб не задирало и не стучал на холодную. Заранее очень благодорю.

What’s up with that song at 5:30? You and @mrsubaru1387 both using it! :)

Thank you from Russian freands!) More video on Russian language)

A good word for the edge break is "chamfer".

Chamfer is the word that you were looking for

Где Шурика Инстаграмм?

8:00 am going hard, you need a polycrystalline diamond cutter! PCD.

German engineering at it's finest

What are you doing @9:10 - filing down your fingernail?
