My EZ30 is at almost 200,000km and it is running stock head gaskets, no leaks, no knocks, nothing. And i redline it pretty hard, head gaskets are not a common failure point on the EZ30.
I gotta say I love my EZ's, I've run them in swaps with no radiator fans and they never overheat! Ok well not never, but they're extremely resistant to it.
You failed to notice the EZ30 is smaller and lighter than the EG33, making it fit almost anywhere the 4cyl will fit. That is a huge difference when doing swaps, like a 914..
Would love to see an ee20 opened up by these guys. I got the dreaded euro 4 in my impreza 😅. 68 thousand miles so far. Only issue I have is engine stalls with ac on sometimes so I don't use ac 😂
First of all i have to say thanks so much for this video to my knowledge its the only one ive seen on youtube showing the differences between Subarus two 6 cyl engines. Awesome awesome job! You clearly showed now why you much prefer the EG33 but i have to say im confused since one of the main guys to work on the EZ30 on youtube from The Skid Factory says the EZ30 is very strong and can take a lot of boost no problems [he covered this in one of his videos not long ago], but he didnt show evidence unlike how you have done here. I guess this is the reason why not many people have modded the EZ30 hard. Finally i have to say here in Australia at least the EZ30 is absolutely not known for head gasket issues at all. its pretty much regarded as bulletproof unlike the subaru 4 cyl engines where most of these problems exist. thanks again!!
There are two generations of EZ30. The first generation was made at the same time as the version of EJ25 that is now legendary for its head gasket issues. This first generation seemingly shared a similar head and gasket design to that EJ25, and suffered the same issues as a result. The second generation EZ30 has a quite different head (and by extension gasket) design, and is known to be very reliable - when stock, of course. Important to note too that both generations are officially designated as EZ30D. The 2nd gen is referred to by the community as the EZ30R to differentiate it. Obviously, this can lead to some confusion when one is reliable and one isn't. Al has turbocharged a few EZ30Rs now, and they seem to do quite well. But like you would expect from a man of his experience, he keeps the boost fairly low on unopened aspirated engines (around 10 PSI ish). These cars are also street cars, so they aren't experiencing the huge constant stress of a race engine. Not to mention that Al normally puts them on E85 which keeps cylinder temps and the risk of knocking down. I really like the EZ30 (I own a Liberty 3.0R-B) but if you were to spend the money building a motor, the EG33 is the better option for your dollars. It's much better for boost, and performance internals are readily available for them because they share so much with the EJ. And if the EG33 is physically too big for whatever you're doing, you'd still skip the EZ30 and go with an EJ20/25 because it would be so much cheaper and easier to build, and there are well known formulas for how much power you can make and how reliably.
@@t_z1030 The first generation EZ30D was produced in 1999, the first EJ255 came about in about 2005. The heads are totally different to that generation EJ, in fact, the intake ports resemble that of a Mitsubishi 4B11T whereas the exhaust ports are similar to that of a late model VW/Audi 4 cylinder. The head gasket design between both EZ engines are remarkably similar, the primary difference is the later model head gasket has room to allow additional oil flow to allow the heads AVCS/AVLS to function. That's it. In terms of reliability, both EZ's are fairly even. At this age, the older one is seen with more leaks/blown head gaskets because it's older and likely done a lot more driving. That should be common sense. Also, you reference boost levels being low on a factory N/A engine with a CR of 10.7:1? That's not very fair, considering the majority of N/A+T EZ30s are being done with GT3076 turobchargers at a minimum, but typically using GT3576 or even GT3582 sizing, which is a very large turbo when you consider the factory turbo that is often seen on EJ engines. The EG33 is a terrific engine... if you have the money. Not only that, it is much, much larger than an EJ (for example, you would have to relocate the radiator if you were to fit an EG33 into a 2002 Legacy RS30 - which comes factory with the rather petite EZ30), also, *this* "and performance internals are readily available for them because they share so much with the EJ.", while true, is a moot point for the EZ series of engines. There is an entire aftermarket for the EZ30 now. You can just about build a high power EZ with off-the-shelf parts. However, 9 times out of 10, people just go with what they have. It's easier, and cheaper. If you're building a race car and couldn't give a shit, EG33. If you're building a street car and you want to keep it *relatively* simple, EZ. Either or, cool engines and make all the right noises. :)

@@Sireristof1332 I know guys that boost ez30's and have for thousands of miles with zero issues. The main head gasket issues on the ej25's was the graphite coating wearing off after 100,000 miles or so. The block etc are great.
This. Here in Russia you'd rather have the body rusted through beyond repair than EZ30 broken. I believe it would last for a million km easily, if not the rust. Reliable as hell, if you don't drink the coolant and piss into the oil then.

No, you're not correct. Yes, EZ30 not meant to be boosted, but this is an excellent NA engine overall. (I'm not speaking of those crazy guys who made that 1200hp impreza with EZ30) The head gasket problems come basically from poor cooling, like failed fan, or low coolant, but it's ok (I guess) for a gasoline engine to require a good cooling. I've been driving H6 for 8 years, and my personal experience is rather positive. It doesn't consume oil (depends on oil though), it starts good at -30 C (and it doesn't overheat at +30 C if the cooling is ok), it never fails in any meaning and, with some service, could last for a million km for sure, and, speaking about service, you don't have to change the time belt, because there's really good chains. If you were gonna to show us some disaster by Subaru, did you consider to make a vid about diesel boxer? It would be nice to have some insight.
you gotta realize this guy has a ton of experience building subaru engines, so he’s probably seen a lot of the common failures, i’m a technician at a subaru dealership and the EZ30 leaks like a son of a bitch, the double front timing cover was a terrible idea, almost every gasket is just silicone, which is prone to leaks if not done properly, chain tensioners go bad frequently, lots of cooling issues. i agree that chains are better than belts as far as maintenance goes but for ease of assembly and disassembly i would much prefer working on an EG33. EZ30s do typically have a lot of headgasket problems but most of the time they leak externally instead of internally. not the worst engine i’ve seen but if it were my choice i would take the EG33 for the larger cylinder separation, partially closed deck, and shorter stroke for more top end hp. also parts for them are much easier to find than the EZ30.
I just serviced a 05 Outback,for a lady,she wants to sell it for 3k,its got no oil leaks,and the motor runs silent...i cannot believe how well it goes,200km but everything works...
@@Fearlessphil100 I've watched his stuff and he has a hella built motor. These guys are claiming that the eg33 will do 700hp standard with headstuds. Having been a mechanic at Subaru, I know for a fact its bullshit. The eg33 is a stout engine, I'm not dissing it, just calling out their bullshit claims.
My boss supercharged his ez30 and has 290kw atw on e100. It's a Raptor super charger kit. He doesn't know how long it will last at this level so it will be interesting to see how his build progresses. EG33 only DOHC? Can you do another video with the head comparison :)
How did your boss's EZ30 go? I just picked up a EZ30R for $300 AUD, a well known Motorsport shop in NZ called 'Possum Bourne Motorsport' does CNC closed decking, + forged rods and pistons, along with head work. They have even improved the timing chain, ARP studs and closed decking allows the motor to be pretty heavily boosted.
I've read a couple places that the EZ30 can take a small to medium amount of boost, and seen a couple rather professional builds with a turbo or a supercharger, but I assume you have a reason for not even bothering that sort of build even with mods. Is there a reason besides the deck design that makes you feel that way? The deck design?
Vielen danke! I appreciate your in-depth explanations and opinions about the EG33. I chose this engine years ago for my Lancia Montecarlo engine swap resto-mod. You give me more confidence in my choice all the time! Great videos.
The bores being Siamesed is actually a point of strength. Take 2jz for example, Siamesed as with quite a few other bullet proof engines. It won't ping at all with those bores, especially being alloy. The engines can also handle 5 to 10 psi in stock form EASILY and can produce 250wkw. The claim that ej25s can do 750hp on stock liners is absolute bullshit. They're known to move around at 500hp. There are plenty of 1200hp ez30 builds around, might be worth doing some research....
The ez36 is siamesed as it has asymmetric connecting rods where as the ez30 dosnt. The ez30 has even thinner walls to add the extra .6 litres of displacement so if he had an ez36 he would say it’s an abomination if the ez30 is a disaster …
Hallo, habe zufällig dieses Video gefunden... Sehr cool. Ich teile die Meinung, der EG 33 ist ein echt guter Motor. Die Nachfolger sind irgendwie verschlimmbessert... Aber meiner braucht 'ne Überholung...
Is there enough clearance from the case main bolts to run Darton MID sleeves in the EG33? You above all would know best if you've used them in the past on any motor. They only require 3-5mm wall thickness where they insert at the base of the sleeve. The top will require a welded in closed deck at least 13mm thick I would say. Tapered edgr deck plate multiple passes until it's filled in. This keeps the cylinders from spreading apart or walking under heavy boost. Holes for the case main bolts aren't necessary because they can be installed with the sleeves out. The bore can be as large as bore spacing less 6mm. I hope it's possible, I'd like to build a short stroke high rpm motor.
EZ30D was a much better version after EZ30, anyway both could take some boost like a Raptor kit gets you to 300~ to the wheel. That's more than enough for a luxury sedan, a SUV or if you want to swap it, definitely more than enough for a SVX, XT or even a 914.
only issue with the EG33 is that it’s a very rare as a standalone motor and the car it came out of the TSX is a rare vehicle and feels wrong to just yank out of 😔
Is it true that you can use ej22 rods and pistons on an eg33? I was told that by a friend but am not sure, itd be great if it's TRUE for using 22 upgraded parts
Why don't you like EZ30? There have been many many boosted builds that have made good power. Yep one had been sleeved but if you can sleeve the EG33 why not the EZ?? Closing the deck isn't too hard either and you could easily make an insert with your equipment and skills... ARP head studs are available and I'm sure high volume oil pumps too. It's lighter, shorter and has better cooling abilities, so it's far from a disaster!
Gutes Video. Mal ne frage. Ich habe mir ne Legacy gekauft mit diesem ez30 Motor und wollte es gerne bei euch bringen für ein Closed Deck zu machen weil ich gerne mit turbo Ausstatten will. Aber wenn ich dich rightig gehört habe machst du das nicht? Weil? Muss ich dan ja wirklich mein Motor zu New Zealand schicken lassen?
Thanks for showing me a eg33 that you can not find anywhere but your shop. Plenty of ez30 I have two of them but now you say there junk. The good old days have come and gone and all the eg33 are gone with them.
The EZ 30 looks wimpy wimpy wimpy. 😂🤣 now EG33 is very much stronger block . I love the staggered oil jurnals. You may lose oil pressure on one side persay but half the crank will still be oil . Awesome stuff THANKS 😲👍👍👍👍👍👍👍😂😃😂
Dass der Motor nicht sonderlich gut tunbar ist is mir schon klar, dafür hab ich ja den impreza. Aber das hat sich findich stellenweis so n bisschen angehört als wär der Motor selbst stock schon quasi über der belastungsgrenze und die erfahrung hab ich bei meinem zum glück bisher noch so nicht machen müssen
So I have a question. Its obvious you see the EG series as the better engine for HP output, but there appears to be less than 30,000 SVX sold globally. But the EZ was used in the B chassis Legacys in sedans and wagons across multiple years, so it seems finding them is much more possible. Also, the EZ went from high compression at first to low compression in 2010, do you think there is something else thats workable with the EZ?
2005-2009 EZ30 can handle 10lbs boost without mods. That's the one you want, plus its the only EZ that has aftermarket support (to a degree) they're still not the most popular but they're gaining a following finally. The open deck is definitely the limitation. If you can get a closed deck, you can build that thing to insane numbers
@@IamTheLocalHam interesting. Why do you think those higher compression engines ended up being the choice compared to lower compression versions that came after?
The ez36 they had to make it even shorter liners to make the extra cc and they use asymmetrical rods to do so because they basically Siamesed the engine
hola Subi Performance como conoces muchos los autos subaru y tienes mucha experiencia, que motores subaru son mas confiable y duraderos en promedio ? 1) serie EJ 20 y EJ25 2) serie FA Y FB 3) serie EZ30 y EZ36 espero me puedas dar tu opinion saludos
@@5325max sure, it'll mount in to the same location, although a tribecca is running an ez36 not this ez30. and you'd need to go standalone ecu, wiring merge and tune as well as fittings for anything like cooling and power steering. plus retrofit a drive by wire to ur eg throttle body. im sure there's more, but tldr, you may want to just modify that ez36 you've got unless you've got experience/bankroll to make the eg swap happen.
are EZ30 so bad? russian friends ( ruclips.net/video/xkvhgdZZBD0/видео.html ) have 399HP at the crank on stock engine with compressor? ok, it's a spec-b, but i doubt the the engine(block) is different! ok, it comes with STi 6speed gearbox.. but if it was so bad they would kill it already :D
No no no this guy is bias. I bought my ez30d for 160$ canadian, good luck finding an eg33 at a bargain. The ez is fine. Not everybody have deep pocket to run a 1000hp subaru on the street. Myself I’l be fine with 350hp at the crank with low boost.
My EZ30 is at almost 200,000km and it is running stock head gaskets, no leaks, no knocks, nothing. And i redline it pretty hard, head gaskets are not a common failure point on the EZ30.

@@altruismfirst6489 if you destroke an ej it can rev up to 12k with ease. If you don’t believe me search “ Betty the Subaru” and give it a look
So is it almost basically an EJ22 with two extra cylinders.
yep, that's how they designed it
I'll have to buy an eg33 one day when you start making closed deck options lol
He could do it any time with that new fancy CNC machine
Good to see them side by side, thank you!
Hello from America... thanks for taking the time to make these videos. Awesome content.
No, you're not correct.
Yes, EZ30 not meant to be boosted, but this is an excellent NA engine overall. (I'm not speaking of those crazy guys who made that 1200hp impreza with EZ30)
The head gasket problems come basically from poor cooling, like failed fan, or low coolant, but it's ok (I guess) for a gasoline engine to require a good cooling.
I've been driving H6 for 8 years, and my personal experience is rather positive. It doesn't consume oil (depends on oil though), it starts good at -30 C (and it doesn't overheat at +30 C if the cooling is ok), it never fails in any meaning and, with some service, could last for a million km for sure, and, speaking about service, you don't have to change the time belt, because there's really good chains.
If you were gonna to show us some disaster by Subaru, did you consider to make a vid about diesel boxer?
It would be nice to have some insight.
you gotta realize this guy has a ton of experience building subaru engines, so he’s probably seen a lot of the common failures, i’m a technician at a subaru dealership and the EZ30 leaks like a son of a bitch, the double front timing cover was a terrible idea, almost every gasket is just silicone, which is prone to leaks if not done properly, chain tensioners go bad frequently, lots of cooling issues. i agree that chains are better than belts as far as maintenance goes but for ease of assembly and disassembly i would much prefer working on an EG33. EZ30s do typically have a lot of headgasket problems but most of the time they leak externally instead of internally. not the worst engine i’ve seen but if it were my choice i would take the EG33 for the larger cylinder separation, partially closed deck, and shorter stroke for more top end hp. also parts for them are much easier to find than the EZ30.
@@bradytollefson9895 Oil leaks are only caused by pcv valve getting stuck and not being replaced. It makes the pressure go towards the seals instead

You are doing an awesome job with the English. Thank you for the video and all the information. (: Blessings on your year
andi: "how do you call the diesel engine"
camera man: "müll" (garbage)
I just serviced a 05 Outback,for a lady,she wants to sell it for 3k,its got no oil leaks,and the motor runs silent...i cannot believe how well it goes,200km but everything works...
Thanks for the information, really enjoyed it. Love this channel!!!
Thanks mate from Cairns Au just bought an Outback H6 donor car
The FA is good it’s just not smart to go over 400 WHP on stock cylinders. And as you mentioned the FA has great cooling.
How is the diesel engine called?
"Müll"?
Da hats mich gebraucht, danke Alex ;)
hahaha 😂
☹ well I love my boxer diesel
If the eg will hold 700hp stock with head studs how much will that build one make?
Joseph Bucko 1000+ easily
Load of shit, they don't.
@@pheonixfps9248 Well this fella's building one right now ruclips.net/video/s-dGlcRb68M/видео.html so we will soon find out cos target is 1100-1200WHP
@@Fearlessphil100 I've watched his stuff and he has a hella built motor. These guys are claiming that the eg33 will do 700hp standard with headstuds. Having been a mechanic at Subaru, I know for a fact its bullshit. The eg33 is a stout engine, I'm not dissing it, just calling out their bullshit claims.
@@pheonixfps9248 Sorry seemed like your reply was to the 1000+ built claim
My boss supercharged his ez30 and has 290kw atw on e100. It's a Raptor super charger kit. He doesn't know how long it will last at this level so it will be interesting to see how his build progresses. EG33 only DOHC? Can you do another video with the head comparison :)
How did your boss's EZ30 go? I just picked up a EZ30R for $300 AUD, a well known Motorsport shop in NZ called 'Possum Bourne Motorsport' does CNC closed decking, + forged rods and pistons, along with head work. They have even improved the timing chain, ARP studs and closed decking allows the motor to be pretty heavily boosted.
@@77knives wow where did you find one that cheap? every where near me wants 2k...
I've read a couple places that the EZ30 can take a small to medium amount of boost, and seen a couple rather professional builds with a turbo or a supercharger, but I assume you have a reason for not even bothering that sort of build even with mods. Is there a reason besides the deck design that makes you feel that way? The deck design?
Eg33 can handle 800hp with bigger headstuds , sign me up lol . I know what my next swap will be now
Thank you. GR8T insights 👍😎 (SUBBED)
p.s.
Your English is EZ on my ears. Good job!
Vielen danke! I appreciate your in-depth explanations and opinions about the EG33. I chose this engine years ago for my Lancia Montecarlo engine swap resto-mod. You give me more confidence in my choice all the time! Great videos.
Just simple curiosity, why won't you make an EZ30 block closed deck? You are simply hate this block in general? I have an Outback 3.0 :P
The bores being Siamesed is actually a point of strength. Take 2jz for example, Siamesed as with quite a few other bullet proof engines. It won't ping at all with those bores, especially being alloy. The engines can also handle 5 to 10 psi in stock form EASILY and can produce 250wkw. The claim that ej25s can do 750hp on stock liners is absolute bullshit. They're known to move around at 500hp. There are plenty of 1200hp ez30 builds around, might be worth doing some research....
The ez36 is siamesed as it has asymmetric connecting rods where as the ez30 dosnt. The ez30 has even thinner walls to add the extra .6 litres of displacement so if he had an ez36 he would say it’s an abomination if the ez30 is a disaster …
Hallo, habe zufällig dieses Video gefunden... Sehr cool. Ich teile die Meinung, der EG 33 ist ein echt guter Motor. Die Nachfolger sind irgendwie verschlimmbessert... Aber meiner braucht 'ne Überholung...
Love the 6 cylinder engines👍👍🇬🇧🇬🇧
Which would be the better motor for high revving application using ITBs
Is there enough clearance from the case main bolts to run Darton MID sleeves in the EG33? You above all would know best if you've used them in the past on any motor. They only require 3-5mm wall thickness where they insert at the base of the sleeve. The top will require a welded in closed deck at least 13mm thick I would say. Tapered edgr deck plate multiple passes until it's filled in. This keeps the cylinders from spreading apart or walking under heavy boost. Holes for the case main bolts aren't necessary because they can be installed with the sleeves out. The bore can be as large as bore spacing less 6mm. I hope it's possible, I'd like to build a short stroke high rpm motor.
What's your opinion on the reverse cooling mod, for subaru?
You guys should build the BMW M57 diesel engine. They are awesome!
EZ30D was a much better version after EZ30, anyway both could take some boost like a Raptor kit gets you to 300~ to the wheel. That's more than enough for a luxury sedan, a SUV or if you want to swap it, definitely more than enough for a SVX, XT or even a 914.
Thank you for sharing this vid! Super cool 😎
my dream is a twin turbo 36 in a gc8 body
only issue with the EG33 is that it’s a very rare as a standalone motor and the car it came out of the TSX is a rare vehicle and feels wrong to just yank out of 😔
Is it true that you can use ej22 rods and pistons on an eg33? I was told that by a friend but am not sure, itd be great if it's TRUE for using 22 upgraded parts
Yep. Few sneaky people swapped EG33 pistons into their 2.2 for higher compression.
Why don't you like EZ30? There have been many many boosted builds that have made good power. Yep one had been sleeved but if you can sleeve the EG33 why not the EZ?? Closing the deck isn't too hard either and you could easily make an insert with your equipment and skills... ARP head studs are available and I'm sure high volume oil pumps too. It's lighter, shorter and has better cooling abilities, so it's far from a disaster!
Gutes Video. Mal ne frage. Ich habe mir ne Legacy gekauft mit diesem ez30 Motor und wollte es gerne bei euch bringen für ein Closed Deck zu machen weil ich gerne mit turbo Ausstatten will. Aber wenn ich dich rightig gehört habe machst du das nicht? Weil? Muss ich dan ja wirklich mein Motor zu New Zealand schicken lassen?
I would love a built eg33 for my 22b replica
That workshop though.. 👌
@6:20 do you mean the windage tray?
Nice to see the differences between the old and new.
I have Legacy 2004 with the EZ30, over 240k km...what would you advice? What can I do to make it serve me another 240k km?
Ничего не понятно
Но очень интересно)
We call it a crank brace
Which of those blocks bolt to the sti 6 speed?
Is it possible to use the cylinder heads of the EZ30R into a EZ36 block without modification?
Thanks for showing me a eg33 that you can not find anywhere but your shop. Plenty of ez30 I have two of them but now you say there junk. The good old days have come and gone and all the eg33 are gone with them.
The EZ 30 looks wimpy wimpy wimpy. 😂🤣 now EG33 is very much stronger block . I love the staggered oil jurnals. You may lose oil pressure on one side persay but half the crank will still be oil . Awesome stuff THANKS 😲👍👍👍👍👍👍👍😂😃😂
Awesome video!
Jetzt mach mir doch meinen EZ30 nicht madig 😢
Der fährt sich ganz wunderbar im Outback als daily und macht keinerlei Probleme mit seinen 240.000km
Naja es geht hauptsächlich ums tunen, und da ist weniger leider nicht besser
Dass der Motor nicht sonderlich gut tunbar ist is mir schon klar, dafür hab ich ja den impreza.
Aber das hat sich findich stellenweis so n bisschen angehört als wär der Motor selbst stock schon quasi über der belastungsgrenze und die erfahrung hab ich bei meinem zum glück bisher noch so nicht machen müssen
unfortunately EZ30 is the much more readily available engine EG33 almost feels like a museum piece how rare it is
Danke!
Hi what Are the cars the run on this engine
From the factory
10x for your video
MORE EG33 VIDEEOOSSSS!!
Давно ждал именно ez30!!!
Diesel EE20, can you ask what you thinck about diesel?
Лайк, после просмотр, у тебя крутая мастерская
need to do a eg33 vs ez36
what about ez36? overheating and cooling?
What oil pump can be used now that the EG33 has discontinued the OEM oil pump?
Ej oil pump is my guess
Can a Eg33 be opened up to 3.8 or 4.0 naturally aspirated ,high compression?
if you custom 83mm stroker crank and darton sleeved use 100mm pistons, it could
6:18 Girdle? An upper oil pan thing, right?
Lower block girdle, upper oil pan casting....
So I have a question. Its obvious you see the EG series as the better engine for HP output, but there appears to be less than 30,000 SVX sold globally. But the EZ was used in the B chassis Legacys in sedans and wagons across multiple years, so it seems finding them is much more possible. Also, the EZ went from high compression at first to low compression in 2010, do you think there is something else thats workable with the EZ?
2005-2009 EZ30 can handle 10lbs boost without mods. That's the one you want, plus its the only EZ that has aftermarket support (to a degree) they're still not the most popular but they're gaining a following finally. The open deck is definitely the limitation. If you can get a closed deck, you can build that thing to insane numbers
@@IamTheLocalHam interesting. Why do you think those higher compression engines ended up being the choice compared to lower compression versions that came after?
What turbo would you run on a stock eg33? Also what injectors?
I think rb26 injectors will fit but this reply might be a little too late
Is the EZ36 pretty much just like the EZ30 but more cc? I take it that the EG33 is the best platform for big power.
no very thin bores no where as reliable as the EG33 or ez30.
The ez36 they had to make it even shorter liners to make the extra cc and they use asymmetrical rods to do so because they basically Siamesed the engine
The Internet:
This NA 3.0 l engine makes 180 kW and redlines at 7000 rpm stock.
But it won't make 700 - 800 hp stock with a race turbo so it's garbage

can you swap the ez30 from a tribeca for an eg33?
I have the same question.
@@5325max sure, it'll mount in to the same location, although a tribecca is running an ez36 not this ez30. and you'd need to go standalone ecu, wiring merge and tune as well as fittings for anything like cooling and power steering. plus retrofit a drive by wire to ur eg throttle body. im sure there's more, but tldr, you may want to just modify that ez36 you've got unless you've got experience/bankroll to make the eg swap happen.
@@alextaitt5604 the tribeca 2003-2009, comes with the EZ30R
Ez is better?
Lmao was not expecting a very strong German accent and then realizing you’re putting them in air planes not cars really surprised me
are EZ30 so bad? russian friends ( ruclips.net/video/xkvhgdZZBD0/видео.html ) have 399HP at the crank on stock engine with compressor? ok, it's a spec-b, but i doubt the the engine(block) is different! ok, it comes with STi 6speed gearbox.. but if it was so bad they would kill it already :D
but EZ30 much easier to swap in sti

No no no this guy is bias. I bought my ez30d for 160$ canadian, good luck finding an eg33 at a bargain. The ez is fine. Not everybody have deep pocket to run a 1000hp subaru on the street. Myself I’l be fine with 350hp at the crank with low boost.
