This video was fantastic. I am saving up for an FA20DIT rebuild and have been trying to learn more about the Subaru engines in general. This was exactly what I was looking for.
Really appreciate the technical information and example engines you set aside to demonstrate to us. I'm pretty much just a beginner when it comes to motors, but thanks to channels like yours I'm understanding and expanding my mechanical knowledge. Fantastic to get ideas and know what is possible from experts like yourselves. My EJ20 is currently undergoing an engine rebuild here in Auckland NZ, and I'm learning heaps in the process. I have been documenting the progress in a special video series called "Project WRX" on our TH-cam channel called diecasttvchannel (aka DCTV). We've subscribed to your channel and look forward to watching many more of your awesome videos. Thanks mate.
Hello. I like to video very much. I have an Ej20 with around 118 Hp, i dont know the exact engine code, and cant seem to find out wich model it came from, i have it en my vw t3 caravelle, but it just took the bevaring for the piston rods, and now im lookout for a New one, could you tell me wich engine i have, if ill send u a picture?
Thanks Brett for the insights on Subaru engines. I'm currently working on a STI conversion of my MY99 Impreza GT including the complete drivetrain with 6-speed gearbox and DCCD. I wasn't sure if the EJ207 always came with forged pistons or just specific model years. So thanks for clearing that up for me.
Excellent video sir! Thanks for all the info - really helped to clarify the differences in motors and applications. I do have one question on the EJ207 and ‘257 (STI’s) though - Q: Are the blocks on the STI motors actually stamped “EJ207” and “EJ257” or will they still just be stamped “EJ20” and “EJ25” and then differentiated by additional stamping/coding to identify whether/not for STI application?
I just bought a 99 Forester S with the EJ25. Has 110,000 miles on it. It sounds pretty good and your video was very helpful. I dont know much about these engines. I live in Amaerica and I like my V8s lol. Is there anything I should really worry about these engines or are they pretty reliable?
Run an AOS / get an equal length header (i know no more rumble)/ get it tuned according to the mods you got/ service regularly with premium synthetic oils..you'll be suprised by the ej257's efficiency & reliability 😎
Thanks you. Informative vid. I am in the market for a turbo SUV and looking at Santa Fe or Sorento. Do you deal with these models? Maybe you can shed some light on reliability of common rail fuel systems, fuel choices (reliable suppliers) and DPF filters. I am reluctant to spend a lot of money on cars with diesels that may be fragile.
At the 5:00 mark you talk about the FA series "being a worthwhile engine from a performance point of view". That was in 2016, do you feel the same way about them now, 5 years later? Also, I've read that the FA series uses the same piston make up that the EJ series did, which made them brittle. Are the FA series pistons also brittle like the EJ series or are they stronger than the EJ series?
I’ve just bought a ‘05/‘06 Liberty GTb tuned bySTI which I’m assuming is the twin turbo EJ20t? Is it possible to swap it for a ej207 straight out of an actual STI? Does anything else need to be changed? Due to physical constraints I had to buy auto, would the gearbox be able to support the extra load? Is there anything that could be improved with the gearbox? TCU tune? I LOVE the size and shape of the gen4 Lib wagon but I’m coming from a Golf R wagon and could always use MOAR. I’m in AUS so would have to get you guys MRT to look at it, I just wanted to ask first so as not to waste time for either of us. Cheers!
Great video, I have 2x ej25 blocks one from an 08 sti, one from an 08 wrx (non sti) the casting stamps is 703 they look identical. Looking to use one in my bug eye. Are these identical blocks? Pistons rod crank? Or does the sti version have any stronger internals?
Not sure if people are still active in these comment sections. I have a scion FRS and I am looking to swap an EJ motor from a salvaged WRX or WRX STI. Im looking for an EJ motor that has forged internals from the factory. Which engine should I be looking for and which Subi does it come out of? Doesn't matter if its 2.0 or 2.5 liter. I would appreciate the info thank you!
Not discussed was the major difference when going from a 2L, in the crankshafts, rods and pistons, but should that be obvious? All newer 2L/2.5L cranks/blocks are directly interchangeable, but the stroke is different. Main & rod bearings on recent turbo EJ20 and EJ25 are identical. If you mix older stuff you will run into issues with the thrust bearing being on main #3 instead of #5. They can be machined to switch to #5.
hey, im a big fan from brasil, I watch all your videos. I have an ej207 that spun bearing and had a cilinder scraped by the piston, with some axyal spacing on the crank... and my friend has a ej204 that is disassembled and ready to sell. is it possible to assemble this ej204 block with ej204 crank, ej207 pistons, rods, heads and eletronics? (i have a spare piston to replace but a ej207 block is too expensive here in brasil) regards and thanks for sharing so much valuable infos on subaru engines!!
My 2013 Scion FRS had a recall on FA20 with Valve Springs that crack and timing breaks! What I wanna know is, what i can replace it with that is a direct bolt on? EJ20 or FA20 out of the 2017 Toyota 86 GT?
What type of turbo kit would you suggest for a 2016 subaru liberty 2.5 premium? i dont intend to race or anything like that. Just looking for something that will spool up quickly for better performance from low RPM. The CVT seems to be flat until it hits the 3500-4000rpm range. I have read in the US Subaru released a Legacy 2.5 B4 Turbo.
Great video on the differences of the Subaru lineup of engines. And, I am glad you said engine instead of motor. ;) Do you all know of any reputable places in the good ol'e USA that we can look into for Subaru engine builds? Thank you either way.
Do you guys have any video on what stuff you use for your rebuilds? or a rebuild video? Ive heard the head gasket and cylinder head bolts needs to be of specific brands or Subaru themselves.
Hey I have a 2008 Subaru Impreza wrx 2.5 turbocharged with an engine EJ25 and I bought a new engine but this one is JE20 almost everything is the same from the old one but have 3 hoses i think is for the coolant but for the old engine only has 2 on the engine so my question is the engine gonna fit on my old engine?
Hi mate. Id love to see a video on differences between the different ej20 blocks. Have bought a TT legacy as an engine donor for my beetle- its an ej20h but no idea how that compares to similar years wrx motors etx
One question regarding the ej20, the wrx block it self is the same as the sti one? Only the inside is different? So it would be possible to just put in the internal if the sti ej207 and i would have all the same advantages? Greeting from Europe
almanu04 get an evo! Some dealerships still have them and are letting them go for less than msrp. I picked up a brand new 2014 evo x gsr in July 2016 for $30,999. Came out to $34k and some change with taxes and license. I can beat on that engine and I don't have to worry about engine issues. But if you really want reliable hp, get a mustang gt. I have (still have it) a 2012 mustang gt and have zero engine problems. It has 77,000 miles. You can get these for even less. Both my cars are stock and I drive them hard.
Hi.. I bought a Subaru ej20 (written on engine body) imported engine (so I have no vin).. I was told by the seller that it came from Australia and probably MY 00-07.. the motor number is 730128 and has 4 valves per cylinder... is there anyway I can know more information on this engine trim and specs.. I searched a lot online and I’m can’t be sure what exactly is it.. any pointers will be very useful..
Bought a used '10 STI with a rod knock engine that turned to have a 2.0L 207 engine in instead of 2.5L 257 usdm that it supposed to have and now I don't know if that's a bad thing or a good thing
I can answer that for you easily. NONE !!! An airplane will require an engine similar to a marine engine - they need a very flat power and torque curve throughout the rpm range. These engines are all designed with a peak torque and power at specific rpm. Put a simpler way, for that aplication you need an engine that will produce, lets say 200 hp at 1200rpm, and still 200 hp at 4500 rpm, with little variation. Look for a marine engine.
hmm , not sure what I was thinking late at night, but the answer is still blatantly NONE. You need an air cooled engine. There is no way you are going to get a rad etc on an ultra light. You need an engine designed for that exact purpose :)
Actually, these engines are quite popular in autogyros, which are often enthusiast home built small aircraft. I have been a passenger in a two seater autogyro with a scooby turbo flat four. I didn't ask the owner which version, but it was beautifully built.
i have a legacy 2005 gt 2.5L turbo so the ej25 and the engine went out at 150k miles ive had that car for 10 years , i bought a jdm 2.0L turbo engine and its getting installed i hope the engine works good and it lasts , i was told by the shop thats doing my swap that the ej20 will be a direct bolt on to my ej25, is that true ?> i wanted to get your opinion . also the 2.0L engine i bought its jdm and i have an american ecu is that going to cause anything to go bad i was told by the shop no and that the car will run the same as the 2.5 , was wondering what your thoughts are
why did you go backwards on size when all you needed was new pistons? I hope the JDM engine is an old type as the newer ones do NOT gave forged pistons you will need a custom ECU tune immediately
On my GT86 (FA20 engine) I've noticed the cam solonoid covers going rusty after just 4 years! Seems to be quite common so that might be something to look out for. Luckily they are easy to get to and only held on my a couple of bolts, so rust treating them is easy to do..
RexSpec555 I'm sure you have already heard about the reliability issues these engines have. There are plenty that have issues when 100% stock. They get covered by warranty. But the ones that mod do not get covered. Many agree that Subaru really needs to address the issue. No sports engine should be blowing with minor mods. Shit, it would be nice if these didn't blow stock. You should be able to drive the sti like you stole it. I just bought a 2014 evo x gsr (just bought it new in July 2016) that I drive daily. I've tracked it and had (and will continue to have) plenty of fun with it. I'm not babying it at all. I have 6,000 miles with no issues at all. I also have a 2012 mustang gt with 77,000 miles. I have beat on that car and have zero engine issues. Subaru better update engine ASAP
The flats are kinda like rotaries... You have to let them warm up before you can beat them or drive them normally. Im pretty sure 80% of people dont let their engines heat up. In an inline its less a problem.
What does the new Forester XT have and how reliable is it? I had a turbo fail on my Audi A4 thus I am hesitating on getting another turbo charged vehicle. I know Subaru engine tend to use up oil, does that include the XT?
So what of those engine is the best engine for a impreza that i can built and stay strong. All the letters and numbers gets me all confuse. I have my eyes on a 2005 rs impreza, obviously i want a better engine to run. When i mean to run is race another car. I knew that to get more hp i have to upgrade internals and everything. I heard something about hybrid but dont know what that is.
Seems the EJ257 is mainly made to cater to the US market which has shitty gas vs. Japan and other parts of the world. This explains why JDM Impreza STI always exclusively employed the EJ207 but thanks to a twin-scroll turbo, significantly higher redline (the forged pistons?) makes equal hp to the larger EJ257 but in a smaller package. The EJ257 makes better torque which Americans seem to want in cars which is likely why it continues to be employed after all these years. However knowing this I wonder how Subaru will go from here, as separate castings & engine sizes are going to be costly for the small company. Given the new Ascent announced the FA24, would the USDM & EU market get a FA24 powered STI while JDM switches over to a high-tune FA20, or all future STI would use one single engine size?
I recently bought a 2010 Subaru Forester (non turbo) which I bought knowing it's an STI. It has the STI badge at the back. The Engine is EJ204. Is it possible that it's actually an STI engine? Am not very good in knowing the differences. If anybody could help I would appreciate. Thank you!
I had been debating building a suby to put in a Factory Five 818. what are your thoughts on building a durable 325hp-350hp, 2.0lt. and how pricey of a proposition would you say that would be?
MRT Performance I'm in the United States so I probably wouldn't be shipping it back and forth overseas to have you all do the work unfortunately, so I was really just hoping to pick your brain and get some ideas from someone with the real knowledge.
You would be well-served to build a 2L or a 2.34 destroker for racing with DS. I have an 818R and have a destroker for it. Supposed to be good for 9-9.5K. Look on the FFR forum/818 if you haven't.
Wait please, the twin scroll turbo its not good for performance but it can be fixed if you do an conversion? What conversion? Just got an EJ207 spec-C vf36 twin scroll I dont know much about this engine or this car, and im trying to learn before doint ANYTHING to it. Its a dream, its a big toy, but its still a car. I need it to bring me from A to B.
So basically the FA20 is the better engine over the EJ25, I was gonna get a 2015 wrx but I'll probably just buy a 2016 or 2017 model to get the newer engine.

Great video...
You could do something similar on turbos. Subaru have used td04, vf22, vf28....
ok
Hello. I like to video very much. I have an Ej20 with around 118 Hp, i dont know the exact engine code, and cant seem to find out wich model it came from, i have it en my vw t3 caravelle, but it just took the bevaring for the piston rods, and now im lookout for a New one, could you tell me wich engine i have, if ill send u a picture?
This was very informative for me thanks for going into these details.
Great insight into these Subaru engines. Glad the brz can handle power. Great expertise
2015, FA20 WRX here! I hope it holds up!
ALT3REDB3AST has it held up?
Great video! Great to hear from a Subaru expert on the various engines and there differences.
thanks
Love your videos! Very informative! Keep them coming especially the FA20 updates and info!
Wow! Great video-thanks. Good to know that my brand new 17 STI has hypereutectic pistons.
Peter Varacalli sarcasm? lol
Yeah.... Im just getting an 04 and swapping for a ej207.
Inverted V12 Powerhouse army the ej207 a lot more expensive than a ej205
Thanks Brett for the insights on Subaru engines. I'm currently working on a STI conversion of my MY99 Impreza GT including the complete drivetrain with 6-speed gearbox and DCCD. I wasn't sure if the EJ207 always came with forged pistons or just specific model years. So thanks for clearing that up for me.
Version 5 and 6 EJ207 never had forged pistons regardless of what he said in the video. I think the RA models might have but not a normal STi.
Or wait, I think it's Version 8 and up that used Hyper-Euteric crappy pistons, the older STi's (like my Version 4 STi) had forged pistons.
5/6 sti ej207 is forged pistons, they also have a smaller piston skirt than previous versions (I pulled one apart not that long ago)
Excellent video sir! Thanks for all the info - really helped to clarify the differences in motors and applications.
I do have one question on the EJ207 and ‘257 (STI’s) though - Q: Are the blocks on the STI motors actually stamped “EJ207” and “EJ257” or will they still just be stamped “EJ20” and “EJ25” and then differentiated by additional stamping/coding to identify whether/not for STI application?
should do a video on the differences of the ej22e, ej222, ej22t, and ej22g
And note what can fit what with no mods needed please .
forgot the ej20k
I'm so glad I found your channel. This is incredibly informative!! Thanks :)
Fantastic information.but I have a question . I have a 2003 Subaru Forester X 2.5L MT (EJ251) Can I swap the engine EJ251 to 2014 or 2015 upper ?
I just bought a 99 Forester S with the EJ25. Has 110,000 miles on it. It sounds pretty good and your video was very helpful. I dont know much about these engines. I live in Amaerica and I like my V8s lol. Is there anything I should really worry about these engines or are they pretty reliable?
Man learned so much, so specific and so on point.
Run an AOS / get an equal length header (i know no more rumble)/ get it tuned according to the mods you got/ service regularly with premium synthetic oils..you'll be suprised by the ej257's efficiency & reliability 😎
Ive got all that and more but still would not want to push past 350awhp on the stock ej257 block
Thanks you. Informative vid. I am in the market for a turbo SUV and looking at Santa Fe or Sorento. Do you deal with these models?
Maybe you can shed some light on reliability of common rail fuel systems, fuel choices (reliable suppliers) and DPF filters. I am reluctant to spend a lot of money on cars with diesels that may be fragile.

Very interesting show in my 2019 Toyota 86 I have a fa20 which is the newest boxer engine
He's like my well informed Subaru 'Aussie' uncle. 😄
I’ve just bought a ‘05/‘06 Liberty GTb tuned bySTI which I’m assuming is the twin turbo EJ20t? Is it possible to swap it for a ej207 straight out of an actual STI? Does anything else need to be changed? Due to physical constraints I had to buy auto, would the gearbox be able to support the extra load? Is there anything that could be improved with the gearbox? TCU tune? I LOVE the size and shape of the gen4 Lib wagon but I’m coming from a Golf R wagon and could always use MOAR. I’m in AUS so would have to get you guys MRT to look at it, I just wanted to ask first so as not to waste time for either of us. Cheers!
Great video, I have 2x ej25 blocks one from an 08 sti, one from an 08 wrx (non sti) the casting stamps is 703 they look identical. Looking to use one in my bug eye. Are these identical blocks? Pistons rod crank? Or does the sti version have any stronger internals?
Can you do a rundown of all the 6 cylinder engines like you are doing on the 4s?
"the heads have had a birthday" hahahahahaha never heard anybody say that about new parts!!
Not sure if people are still active in these comment sections. I have a scion FRS and I am looking to swap an EJ motor from a salvaged WRX or WRX STI. Im looking for an EJ motor that has forged internals from the factory. Which engine should I be looking for and which Subi does it come out of? Doesn't matter if its 2.0 or 2.5 liter. I would appreciate the info thank you!

(i have a spare piston to replace but a ej207 block is too expensive here in brasil) regards and thanks for sharing so much valuable infos on subaru engines!!
My 2013 Scion FRS had a recall on FA20 with Valve Springs that crack and timing breaks! What I wanna know is, what i can replace it with that is a direct bolt on? EJ20 or FA20 out of the 2017 Toyota 86 GT?
The newer fa20s are better but you could also just get new valve springs
What type of turbo kit would you suggest for a 2016 subaru liberty 2.5 premium? i dont intend to race or anything like that. Just looking for something that will spool up quickly for better performance from low RPM. The CVT seems to be flat until it hits the 3500-4000rpm range. I have read in the US Subaru released a Legacy 2.5 B4 Turbo.
All those engines and my 2001 Legacy outback in the carport needing one...✌️😢👍
How do you get these engines so clean ! Look how big that engine in the back is..looks really wide.
Great video on the differences of the Subaru lineup of engines. And, I am glad you said engine instead of motor. ;)
Do you all know of any reputable places in the good ol'e USA that we can look into for Subaru engine builds? Thank you either way.
great video, makes me wanna bring my subie over to your shop in australia to modify it :D
Do you guys have any video on what stuff you use for your rebuilds? or a rebuild video? Ive heard the head gasket and cylinder head bolts needs to be of specific brands or Subaru themselves.
sorry not in that detail
Very informative, thank you.
Hey I have a 2008 Subaru Impreza wrx 2.5 turbocharged with an engine EJ25 and I bought a new engine but this one is JE20 almost everything is the same from the old one but have 3 hoses i think is for the coolant but for the old engine only has 2 on the engine so my question is the engine gonna fit on my old engine?
Hi mate. Id love to see a video on differences between the different ej20 blocks. Have bought a TT legacy as an engine donor for my beetle- its an ej20h but no idea how that compares to similar years wrx motors etx
Thanks for the information. Love the channel.
Love the simplicity.
From the us doing a RHD swap on a outback legacy with a twin scroll 2.0 not forged unfortunately
could you do a video on what JDM engines can be swapped into certain USDM models specifically the bugeye?
One question regarding the ej20, the wrx block it self is the same as the sti one? Only the inside is different? So it would be possible to just put in the internal if the sti ej207 and i would have all the same advantages?
Greeting from Europe
IYO, has Subbie fixed their famous ''blown head gaskets'' issues with their newer models, say 2016 onwards ? Thanks for the great video.
My legacy 2012 ,i changed engine because blown head gasket 😟. Shit engine. I think so right now is a Fa engine or Ej25
Love your videos very informative for Subie enthusiasts!
thanks
I'm kinda new to the ej25 motor. I have a 01 impreza rs2.5. Nothing extra just stock, do sti come in ej25 engines too or only ej20?
just to clarify a 1999 subaru outback engine would be dohc and would need new heads before you would even consider adding a turbo to it?
Wowowo awsome video
i guess im screwed coz i got the 2016 sti. it sucks paying all that money and have a weak motor. whats your advice? maybe trading it in?
wait for the new STi with the FA20 OR trade it for a WRX!
almanu04 get an evo! Some dealerships still have them and are letting them go for less than msrp. I picked up a brand new 2014 evo x gsr in July 2016 for $30,999. Came out to $34k and some change with taxes and license. I can beat on that engine and I don't have to worry about engine issues.
But if you really want reliable hp, get a mustang gt. I have (still have it) a 2012 mustang gt and have zero engine problems. It has 77,000 miles. You can get these for even less.
Both my cars are stock and I drive them hard.
super informative!! well done!
thanks
wow awesome video, very informative
Hi.. I bought a Subaru ej20 (written on engine body) imported engine (so I have no vin)..

I searched a lot online and I’m can’t be sure what exactly is it.. any pointers will be very useful..
North of 16k on my 2015 STI build at the moment. 675bhp
Have you had or dismissed the idea of a front mounted turbo setup on an EJ engine in a GC8? Would you advice against such a configuration?
for road cars a FMIC these days is not needed unless you plan HUGE mods
The Aussies are Badass! Go MRT!
Bought a used '10 STI with a rod knock engine that turned to have a 2.0L 207 engine in instead of 2.5L 257 usdm that it supposed to have and now I don't know if that's a bad thing or a good thing
very informative cool thanks man
thanks for informative video , can you advise me which of these engine would be better for ultralight airplane
hmmm, not sure,we have never done one for that application

I hope the JDM engine is an old type as the newer ones do NOT gave forged pistons
you will need a custom ECU tune immediately
Whats the most common failure you see on a subaru engines? like the non-turbo ones because less people trash on them
it varies!
Matt Coffey man! Those engines suck. I'm happy I can redline
On my GT86 (FA20 engine) I've noticed the cam solonoid covers going rusty after just 4 years! Seems to be quite common so that might be something to look out for. Luckily they are easy to get to and only held on my a couple of bolts, so rust treating them is easy to do..
What did the owner do to bring in an FA20 engine into the shop so quickly?
Interesting video, nice calendar.
great info!
Great vid good information!
Amazing explanation thank you!!
Was thinking of getting an 08 Sti.. Is the fa20 a better bet in the g4 wrx?
Nice video mate
If you leave an EJ25 STi completely stock, will you still have engine reliability issues or is that only when you start modifying?
i have 17 sti that is completely stock. at 1838 miles, i cracked a piston in cyl 4.
Well that sucks! Were you rev limiting it or otherwise driving in a way that could cause damage?
RexSpec555 I'm sure you have already heard about the reliability issues these engines have. There are plenty that have issues when 100% stock. They get covered by warranty.

Subaru better update engine ASAP
I love FA's. I love ej's too. I just love subies.
Que motor es mejor? Ej o Fa. Saludos desde chile
great info!!
my f20 rod knocked bone stock no mods toyota didnt want to help me and wanted 10k$ 32k miles on the motor.. sued the fuckers now i have a sti :)
thatonebeone I have a friend that had the same issue with his stock STI @ 18k... After the law suite he now driving 3 series.
john jay That's funny because my 5 Subarus (all turbo and tuned ) I've had over the years have been reliable as fuck.
The flats are kinda like rotaries... You have to let them warm up before you can beat them or drive them normally. Im pretty sure 80% of people dont let their engines heat up. In an inline its less a problem.
Inverted V12 Powerhouse Care to explain why?
Is the liberty ej20t and s-gt ej20t has the same engine or there is difference?
What does the new Forester XT have and how reliable is it? I had a turbo fail on my Audi A4 thus I am hesitating on getting another turbo charged vehicle. I know Subaru engine tend to use up oil, does that include the XT?
they are a good car
Fanbtastic video, thanks a lot.
So what of those engine is the best engine for a impreza that i can built and stay strong. All the letters and numbers gets me all confuse. I have my eyes on a 2005 rs impreza, obviously i want a better engine to run. When i mean to run is race another car. I knew that to get more hp i have to upgrade internals and everything. I heard something about hybrid but dont know what that is.
Seems the EJ257 is mainly made to cater to the US market which has shitty gas vs. Japan and other parts of the world. This explains why JDM Impreza STI always exclusively employed the EJ207 but thanks to a twin-scroll turbo, significantly higher redline (the forged pistons?) makes equal hp to the larger EJ257 but in a smaller package. The EJ257 makes better torque which Americans seem to want in cars which is likely why it continues to be employed after all these years.
However knowing this I wonder how Subaru will go from here, as separate castings & engine sizes are going to be costly for the small company. Given the new Ascent announced the FA24, would the USDM & EU market get a FA24 powered STI while JDM switches over to a high-tune FA20, or all future STI would use one single engine size?
Great video!
you earned a new subscriber lol great video very informational
thanks
I recently bought a 2010 Subaru Forester (non turbo) which I bought knowing it's an STI. It has the STI badge at the back. The Engine is EJ204. Is it possible that it's actually an STI engine? Am not very good in knowing the differences. If anybody could help I would appreciate. Thank you!
Which its the best and easy engine swap for a 2003 aubaru legacy wagon L?
will a 2005 ej20 wrx sti engine go straight into a version 1 wrx with little having to be changed?
So Ej207 with a modern twin scroll turbo is the way to go?
If you have an ej205 in an impreza rs 05, are you able to swap to a ej207 direct?
Hello brothers, i has question : you can put turbo a naturally aspirated engine uj255?
I had been debating building a suby to put in a Factory Five 818. what are your thoughts on building a durable 325hp-350hp, 2.0lt. and how pricey of a proposition would you say that would be?
its best you call us 0297674545
MRT Performance I'm in the United States so I probably wouldn't be shipping it back and forth overseas to have you all do the work unfortunately, so I was really just hoping to pick your brain and get some ideas from someone with the real knowledge.
:(
You would be well-served to build a 2L or a 2.34 destroker for racing with DS. I have an 818R and have a destroker for it. Supposed to be good for 9-9.5K. Look on the FFR forum/818 if you haven't.
And my question is seen I have a fa20 boxer engine is where would I look for heads for that engine
great video ! thanks
can you do a video for the twin turbo ej20 how different are they to the ej20 sti or 2.5?
Wait please, the twin scroll turbo its not good for performance but it can be fixed if you do an conversion?
What conversion?
Just got an EJ207 spec-C vf36 twin scroll
I dont know much about this engine or this car, and im trying to learn before doint ANYTHING to it.
Its a dream, its a big toy, but its still a car. I need it to bring me from A to B.
best visit your preferred Subaru specialist before you do anything
:)
Yes, thats the difclt part of living in Russia. Find this guys....
Anyway, Thanks!
v7 ej207 vs v8 ej207 ? ej207 is stronger to my understanding ?
Which gearbox properly suits ej25 Subaru forester?
nice video mate...
So can I put all the parts from EJ257 to my EJ205 built shortblock ?
Awesome info Brett!! thank you
Great video! Cheers m8
thanks
So basically the FA20 is the better engine over the EJ25, I was gonna get a 2015 wrx but I'll probably just buy a 2016 or 2017 model to get the newer engine.
Any heads up for 2013 WRX common problems?
Can the ej20 and the ej255 use the same clutch kit system??
Great info, thank you.
thanks
