- Flatirons Tuning Tech Tips - Information you need if you are considering a JDM Engine Swap
It is pretty common for us to get questions about directly swapping a Japanese Market engine (JDM) into a US market car (USDM). And it would be great if it was as simple as it seems like it should be to just install the engine and move on down the road.
Unfortunately it isn't necessarily.
If you are considering doing this swap, there are some things that you need to know so that you can make a good decision about going down this path. So we have put together this video to answer the most common questions that we get asked about doing this swap.
Hopefully this helps you, and thanks for watching! - ยานยนต์และพาหนะ
Thanks for covering this. You saved me from a hellish trip down a nightmare of a rabbit hole!
Ha! Glad we could help.
Thanks for watching and Stay Tuned!
@@FlatironsTuning Looking around for a core for my 2013 WRX. NOTHING to be had. Is it possible to use the case and heads from a JDM to build a USDM unit?
Thanks for all the info. Keep it coming!
Thanks for watching. Stay Tuned!
If you do your homework you can get a non avcs 2.0 from an importer and swap out the intake and exhaust manifolds, couple cam pulleys, and sensors and you'll have an excellent running engine. I'm 3 years on a JDM 2.0 swap and I'm extremely happy with it. Even came with huge ported heads and ran great with minimal tuning.
Nice! Thanks for watching Justin.
Which gaskets did you replace ? Or should replace when swapping parts from us ej205 to the jdm non Avcs ej205. Need help
There's no certain gasket Justin is 100 percent correct there's certain ones that are even ezer than that I didn't even have to swap cams pully just needed the US intake manifold and then boom running and using usdm ecu and cob access Port going on almost 2years at almost 400 wheel these guys are awesome but this video is way way off
An avcs engine plugs right in no problem without changing anything, I don't know what this dude is talking about saying you have to change stuff, you just won't avcs without the jdm ecu. Go to iwire and they explain everything.
I know this is an old post but what kind of tune did you get? I'm in a similar situation where I had a jdm engine put in my 08 wrx. It's at a shop now, it'll idle but has a slight misfire. Again I know this is an old post so thanks for your time.
Great advice in this video. Doing the Ej20x JDM swap in my 08 Impreza. Ended up using a USDM ecu to pass inspection. Had to use USDM cam. Engine CAME WITH turbo down pipe that was cut low (necessary to fit).
USDM exhaust and intake cams? Or just exhaust cams?
I love this channel!
Thanks Ryan!
Experience makes all the difference😎 thank you again for imparting so much subi knowledge! There are too many jaws flapping out here that haven't even done a swap but who are confusing the community by reciting wrong info.
Thank you very much for that, and thanks for watching!
FlatironsTuning : Thank you so much for your info on the AVCS difference between JDM and USDM. This whole JDM thing is new to me as of about 1 month ago. That’s because I am looking to replace the 2.5i motor in my 2009 Subaru Outback at the suggestion of various comments I have received from a Subaru online forum I joined to sort out what I do not know and the best way to solve my problem. I had a feeling it was not going to be as easy as simply pulling the old engine out and bolting the JDM in. I also had a feeling I was not going to do the work myself. I have no problem turning a wrench. But at a certain point I step back and let the pros have at it. And your video convinced me that having someone else do the work is most definitely the way for this guy to go. When there is the possibility something out of the ordinary may go wrong, that’s the time I choose to have someone else do the work with a warranty to back up that work.
Once again, thanks for the very informative video. You have helped put my mind at ease :-)
Great comment, and glad we could help!
Thanks for watching!
i guess Im randomly asking but does anyone know of a trick to log back into an Instagram account?
I was stupid forgot my account password. I love any tricks you can give me!
@Ishaan Andrew instablaster ;)
@Gavin Hank i really appreciate your reply. I found the site through google and I'm trying it out atm.
I see it takes a while so I will get back to you later with my results.
@Gavin Hank It did the trick and I finally got access to my account again. I'm so happy!
Thank you so much, you really help me out !
I’ve done plenty of the EJ20X swaps, you can swap your USDM turbo setup and be just fine. You can run the jdm cams and cam gears with a 2.0 WRX timing kit. All of the sensors are the same as, at least, my legacy gts I’ve done it in. Retard the exhaust cam gears 2 teeth to keep them from free floating. Get a tune for the higher compression and such. I’ve been running it on the track for over 40 hours of continuous beating and it’s loved it so far 👍🏽
I actually just did the ej20x swap to my 2013 wrx with a VF48 instead of using the stock VF52 and TD04, gotta clean it up a bit but it’s running off a base tune right now, after doing some heavy research seems like it’s better for me to just leave the exhaust side avcs unplugged and just go get a tune And build the the USDM 2.5 I pulled out.
@@_icdonuts yep that’s what I do, leave the exhaust side unplugged, retard the exhaust cam gears two teeth. I just swapped to a VF44 EWG setup because I was lacking in low end power. Now I have all of it 😂
I just did a swap from a 2.5 to 2.0 Jdm but having problems won’t start can you guys help
With my ej 255 b25 I swapped the engine it’s not working what can I do to get it to work? If I swap the intake manifold and wringing harness will it work ?
I don’t know what to do I feel hopeless
Pleasure to watch this video this guy discusses the issue in-depth, from his vast experience. May I suggest getting a remote microphone to improve the sound and take videos to the level of professionalism.
Thanks for watching Isaac!
Old video I know but just a little FYI that you might find interesting..during Subaru factory training we were told that tube was to help prevent oil aeration in the pan... I no longer remember exactly how it was supposed to work or if it was really gone into that deep but I definitely remember that is what I was told by Subaru is the purpose of that port/tube.
I have an 07 Forester. I put an 07 JDM legacy avcs in had to add pcv to Japan harness and repin the temp sensor to allow for the us temp guage wire. Took 2 days and everything runs great. I didn't change cams, crank pulleys anything
Did you use the usdm ecu?
I did the same thing! @jrodPhxPhoto my only problem is the engine has rough idle up to 1500rpm before it smooths out still diagnosing the issue. Already replaced spark plugs, wires, and swapped out Ig coils just to see if that changed anything with no luck
@@hal0mann check to see if your timing belt jumped a tooth, I'm having similar problems with a JDM swap with my bugeye
Oh boy. I have an 03 bugeye that im doing a jdm swap. Im getting an avcs motor and jdm avcs ecu. Is that what you did too?
@jackson lieber my post/comment was meant for you asking if you went avcs motor and ecu
I have a 1995 impreza outback with a full 02 usdm wrx swap including dash. Been having a jdm ej205 in for almost 3 years with no issues. It is a single avcs motor that is ran by a usdm ecu. At the time I didn't have an accessport so it got protuned using open source. I did not change a single thing on the motor except the intake manifold since the motor came out of a 2004 forester xt which was drive by wire and everything on the factory manifold was different. My avcs does not work since the usdm ecu are not equipped to run that but other than that it works perfectly fine. I hope this info helps anyone out there trying to swap their car or in the market for a new motor. and one last thing, a tune is a must if you go jdm motor. Usmd motors have air tumblers and the jdms don't, you just simply leave them unplugged and your tuner will turn those codes off.
Francisco Rayado hey so I just bought an engine that has single SVCS for 1300 looks really nice. But I have a question! What parts did you have to swap in order to make it work on the USDM WRX? Mine is an 2002!
@@Cruz0604 The intake manifold was really the only thing and that's because the wiring on the manifold is very important and has to connect to the rest of the harness. If you unscrew your oil cap and look inside it will say what year your engine is from. Mine has "04" stamped on it.
You can find jdm ej 255 sti motor that are plug and play 2006-2008maybe even2004 Forester sti's were made to usdm specifications but never imported the U.S.
Currently undertaking swapping a jdm ej25 into an 05 impreza 2.5rs biggest differences I've noticed is the intake and wiring are slightly different. Do they both need to be swapped or can it be used as is? Any recommendations?
Hey man! I’m swapping a 2.0 2010 Nissan Sentra usdm with jdm, anything to look out for?
Dropped 9 hours ago. Glad I came across this.
My wrx has a jdm swap and I’m planning on reverting that back to an ej255
Very informative! Wonder if you can help me with this. 05 Avalon, 3.5L V6....JDM. After install... starts, runs smoothly for 2 sec. Then dies. I can do this repeatedly... and can even throttle up smoothly.... only for 2 sec. WHY???
Any insight is appreciated!
Thinking of swapping the sti jdm vers.10 ej207 into my 2014 sti, timing tensioner failed and uncle Rodney came knocking.
I chose the vers.10 as its directly from the same chassis as mine, better internals than the 257, elh, twinscroll, higher revs etc etc. Both 32bit ecus, what I've dug up from Nasoic is its not too terrible to get the engine cooperating with the car harness wise. But if I was going to through all that I figured it would be best just to go for a standalone ecu as tuning the jdm ecu sounds very tiresome and limited and converting the engine to the usdm ecu sounds like a harness nightmare. Standalone would give me a lot more future tunability down the road, rolling antilag, launch control, tune the sensors to read the jdm so as to not have to go through the conversion process.
As for the turbo....
**Could I just cut the flange off my existing downpipe to turbo section and weld the proper fitting one for the vf47?**
I have the Cobb turboback, I would prefer to reuse it as I quite like the deep resonance from it.
And I do prefer a twinscroll over a single scroll, I don't plan on doing anything crazy turbo wise, I figured I could just have a turbo shop bore out the compressor housing to fit a larger compressor if I wanted more oomf out of the vf47 in the future.
Thanks for watching and thanks for your question.
The Twin Scroll turbo uses a different flange, so you couldn't modify the Cobb bellmount to work. You would need to replace it unfortunately.
I'd say just stay single scroll as it wouldn't require as much tuning to adjust. Keeps it simpler and all of the exhaust, turbo, and gaskets, etc. are unchanged. It is much harder to find the Twin Scroll parts (though we do try to keep them in stock as much as we can).
The V10 should be fairly easy to tune with the USDM ECU. A local rally customer of ours just did this.
Talk to your local Tuner and you will have a better sense of what your options are.
Hope that helps and Stay Tuned!
i have ej207 v9 with dual avcs and i'm wanting to put it in my2009 wrx what would need to be swapped over?
Got a 97 accord with a Jdm f23a runs and drives but emissions has me in a bind I got a new cat for a 98 accord but wanted to know if it will pass smog in California
Is there a way to run that bottom left port and a tune so you can use it and not throw a engine code
I know this is an old post but my 2008 Impreza has a ej205 jdm swap with avcs but without the turbo, the old owner made it run without the turbo somehow, I think they left the old ecu that doesn't has the capability to move the avcs, it has the wiring and all that but I think it isn't working bc I have the p0011 and p0021 codes always, I have changed the avcs , the solenoids , the banjo bolts and both codes are still there ,the car is running but I feel is underpowered and it has like a little misfire below 600 rpm in idle ( not always), sometimes it shut off when I let the revs come down fast like when you are in traffic and you have to brake in neutral if you know what I mean.
should I put a turbo into it and the ecu with the avcs option or can I still run it without the turbo just with a proper ecu, what do you suggest?
I really want to shut that engine check light off, is annoying
So what do I do I have swapped the ej255 b25 into my 2006 forester and it isn’t turning over
What are common issues when swapping an EJ257 v10 to an EJ207 v10? they both have dual avcs. I'm guessing its the cam sensors.
I've a question maybe you'd be able to help me. I have a 2002 2.4 V4 Toyota Camry. I love my car but recently I've noticed that white smoke has been coming out the tailpipe (Only for a couple of seconds and only in the mornings) . I had it checked out and my mechanic is saying my head gasket is going out. I've noticed that I've been losing coolant every so slightly. My engine has 134k miles on it. My mechanic is charging me 1500.00 to replace the gasket. I have many JDM shops that sell used engines around my area for 1200.00. Labor is around 1K to put it in. A total of 2200.00. I also found a rebuilt engine on offer up for 900.00 + 1K to put it in but I don't know who rebuilt the engine. I don't do any tuning and I'm not a mechanic myself. I just want reliability and I want to get to point a to point b. I live in So Cal. What do you suggest? Thank you for your video it was very informative and your advice is very much appreciated.
Great video. I have 2011 wrx and I’m almost done swapping an dual avcs ej20x from my
Single avcs ej255. Talked to a local Subaru tuner and he assured me that I’d only need to swap the exhaust camshafts and exhaust avcs sprockets with the old static camshafts and sprockets and leave everything else in terms of sensors. And with a custom tune to my usdm ecu I should be good. Would you agree? I’m gonna be dropping the engine in soon and after seeing this video I’m getting cold feet about what I’ve done so far lol
Thanks for your question. You are basically correct. You will also have to swap your intake cams in for USDM ones for your ECU to read them properly. But everything is largely unique on the EJ20X, so I'm not sure if their sensors will properly read the US cams.
Also, keep in mind that this is a high compression engine (9.5:1), so unless you run the car on E85, you will have to be very careful about knock as you tune the car.
I hope that helps, and Stay Tuned!
did you end up doing that? i did not change the cams when i did the swap on my 13 wrx and my tunner said that the cams or left cam is not working properly. i was also having a p0021 code or intake cam position over. would not changing the cams cause this? let me know your thoughts
Hi, could you also do a video about the same issue but regarding European cars? From what I know, ours are built in Japan, but they are made different for the eu market. Thanks!
Thanks for your question. At this point, that would be difficult because we don't get to see much of the EDM cars over here. My understanding is that the EDM cars get mostly JDM components in terms of cams, etc., so it should be close to what the JDM cars have. But there certainly may be some critical differences. Unfortunately I just don't run into them here in the US so I can't advise what to look for.
I hope that helps at least a little and thanks for watching!
FlatironsTuning thanks for the response:)
What happened to part 5??
I have a 13 wrx with high miles on a questionable bottem end. What about the ej20x or ej20y shortblock with the ej255 heads, intake, exhaust, and electronics. The high compression forged pistons in the ej20x block look like they will make up for the loss in compression with the ej20 block ej25 head combo and it migh possibly end up around 8.0 to one. I cant find anything on this anywhere
Thanks for your question. What you are talking about here is basically a reverse hybrid swap. This introduces some interesting issues, but most likely the biggest one will be the quench area between the piston and head. You will end up with a mushroom shaped combustion chamber, and that is not ideal at all, and can present issues with hot spots and detonation.
There is also the issue of what head gasket you would run because the cylinder will not made up with the head ideally.
In short, I would recommend against trying this.
Hope that helps, and Stay Tuned!
Could you use a haltec on this engine? And keep it all running close to oem ? Wouldn’t that let tuning work better?
Thanks for your question. Yes, if you ran a standalone like a Haltec, then you could easily configure the sensors and pick-ups to what you have so that you could properly tune the car.
Thanks for watching and Stay Tuned!
So I have a 02 wrx with a jdm v7 sti transmission. The previous owner had it wired up to his stock usdm 02 wrx ej205 but it blew and I bought it with no motor so if I get a non avc jdm ej205 I don't have to change the cams and pretty much just transfer all the usdm engine accessories like the intake manifold etc. Also would a tune me nessary? Thanks love your videos!
Thanks for your question! I'd say that from what you are saying, yes, you should be able to bolt up a non-avcs basically as the engine that came out. I'd definitely recommend getting the car tuned with the new engine to make 100% sure that it is running properly with the new engine.
Good luck with your swap!
Yup
What do you suggest for a solution for ecu and wiring if you happen to have a 97 LOB w/ JDM ver4 ej207.
If you are doing an older swap where there aren't any options to tune the car with the factory ECU itself, your best bet is a stand-alone ECU. Something like a Haltech, Vi-pec, Autronic, AEM-EMS, etc. And if you go down that road, you don't have to worry so much about trying to merge your harness with the JDM one as well.
Good luck with your swap!
So im still s little confused . I have a v9 ej207 I've gotten with the iwire avcs harness. The v9 seem to have a immobilizer
I've read i can use either a v8 ecu or even a v7 ecu can you all confirm that to be true for tuning?
That is a good question. We have not run into any of the JDM ECU's with immobilizers. They definitely bring their own sets of complexity. I believe that V9 is dual AVCS, but V7 and V8 are single. That would be an issue, but that is all I have off the top of my head.
I hope that helps and Stay Tuned!
I'm swapping in a ej20x into my svx and I'm at the tail end of the swap. One major thing holding me up is I'm using the ej20y wiring harness and ecu but can't find any diagrams to power the ecu? Any help appreciated!
Thanks for the question. That isn't something we have, but hopefully someone that sees this can help.
Good luck with the swap and Stay Tuned!
I'm hoping it will all work together but I have a 6 speed transmission in a 02 bug eye my 04 sti engine started knocking so I got a 06 jdm ej207 v9 with the ecu I'm assuming my ecu right now is still a 02 wrx ecu if anyone has any helpful suggestions please let me know
Thank you for your question. That is a tough one. The short answer is that the USDM and JDM ECU's work differently so at a minimum, they are not plug and play replacements for each other.
I'd recommend starting by deciding which ECU you want to run, and then work through the engine components that you need, etc.
Hope that helps and Stay Tuned!
I really hope you are still replying, i have an 02 wrx with a jdm ej20 and turbo xs exhaust and cold air intake, accessport on the way, but can it be tuned even tho it’s jdm? Can the accessport still read my car? Also sometimes it shifts hard in 3rd gear, is low transmission fluid a possible reason?
Thanks for your question. If you have the JDM ECU, then the Accessport will not communicate with it. You would need the USDM ECU to use the USDM Accessport. But if you do have those, then yes, your car can be tuned.
Thanks for watching and Stay Tuned!
@@FlatironsTuning so it won’t even ready how it’s been driving? Like at all?
EJ20x swap into USDM 08-14 WRX.. do Intake cams need to be swapped? Or can the ej20x intake cams be used and just leave exhaust AVCS unplugged? Looking to keep my USDM ECU, VF52 turbo/headers, and intake manifold. I don’t have emissions checks in my area.
Thanks for your question. I'd recommend taking a look at our blog about the EJ20X and EJ20Y:
www.flatironstuning.com/blog/everything-you-need-to-know-about-the-ej20x-ej20y-engine
The short answer is no, you can not use the EJ20X intake cams or exhaust cams. That engine is not a straight forward swap into a USDM WRX.
Hope that helps and Stay Tuned!
@@FlatironsTuning I'm curious.. if you use the JDM cam sensors, can't you just use the JDM cams also? I've seen videos of guys swapping the EJ20x into their WRX or LGT and just leaving exhaust AVCS unplugged, then having the car tuned. You're saying this can't be done?
@@bankruptsee You can't use the US ECU with the JDM cams. The pick-ups are different so the USDM ECU won't get the signal it needs.
On the exhaust side, you can't run the exhaust AVCS. Leaving the solenoids unplugged is a starting point, you need to deal with the intake AVCS issue.
If you don't get that working, the car will be more or less in limp mode.
Also, with no control of the AVCS gears, there is the possibility that they can drift, and you really don't want them to do that.
hey man you can swap the engine out without changing the cams but you will be running with less power. i just had my car tunned 2 days ago and did the same swap (13 wrx ej20y) and the car barely hit 190hp on the dyno. tunner said the cams are not working properly and that the cams have to be changes. short story i know its the cams. This guys right. a lot of wrong info on the web and this info i correct. i know have to take the car back to my shop and get the cams replaced for the motor to run the right way. i havent had the codes pop up again but if they come up again i know for a fact that is the issue
What about the fa20 jdm? Currently having ecu problems and trying to figure out if I buy a brand new ecu from Subaru if it will just be plug it in reinstall AP and go
Thanks for your question. We haven't worked with any JDM FA20's yet, but the first thing I would do is look at the cam position sensors. I wouldn't be surprised at all if they were different.
I would not assume that a new USDM ECU would work unless you can trouble shoot your issues down to the ECU function itself.
Hope that helps and Stay Tuned!
Did u solve the problem?
Any update?
Can you put nonavcs cams in a avcs cam head on a 207
Thanks for your question. Yes, AVCS cams will fit in non-AVCS heads, and Non-AVCS cams will fit into AVCS heads. If you do put the Non-AVCS cams in an AVCS head, you just need to keep the AVCS oil lines installed to make sure that the cams are properly oiled.
Hope that helps, and Stay Tuned!
Im looking at a jdm ej205 with a wiring harness and ecu. It does have avcs. Would I just need to move some pins around to make the ecu more tunable? What else should I know?
Thanks for your question. No, the Architecture of the JDM ECU is totally different from the USDM ECU.
If the JDM engine is non-AVCS, your best bet will be to stick with the USDM ECU from a tuning standpoint.
Hope that helps and Stay Tuned!
@@FlatironsTuning The engine has avcs. So should I go with the jdm wiring harness and a us ecu.
@@blobeye_rsti Is this an EJ20X or EJ20Y with Dual AVCS?
If you want the AVCS to work, and you want to be able to tune the car, you would either have to switch to the cams to US spec as described in the video, and then do a harness merge to a USDM ECU that can drive the AVCS funcion you need.
If you don't want to go to that extent, my best advice would then be to delete the AVCS, and tune the car with the USDM EJ20 ECU.
The steps to do that are similar to installing a full EJ25 engine as we talk about in this video:
th-cam.com/video/6Xzopgayw7c/w-d-xo.html
Hope that helps and Stay Tuned!
I just tested the compression on my engine and came out really low. I was wondering if I do a non avcs ej205 v5 would it pass emissions?I'm here in Colorado
Thanks for your question Jose. Certainly keeping your stock ECU will help a lot to improve your chances. When you say that your compression numbers were low, how low are they? Were any cylinders below 100 psi? Also, did you do the test with your plugs in or out?
FlatironsTuning it was 110 on all 4 cylinders I did pulgs out.
That is a little low, but actually not that out of the ordinary up at out altitude. It is also a good sign that all 4 cylinders were close. Typically, if one cylinder is damaged, it will test well below the other 3. I'd recommend that before you look at installing a new engine, that you get a solid diagnosis as to what may be going on with your engine. Best to make sure that there isn't something simpler to repair or replace that has failed.
Good luck!
FlatironsTuning Thanks for all the info I guess my next step is to have a leakdown test done to it.
Ya you can
Say I were to do a swap and given the different ecu architecture, would I be able to read obd2 codes with a scanner on an EJ207?
Hello Brandon. That is an interesting question, and I'm not sure. My guess is yes, because it wouldn't seem to make sense for them to put in a completely different set of DTC's just for a different market. But since most of the fault codes that we get are emissions based, and they don't have the same emissions requirements in other markets, they may not work with a USDM code scanner...
I'll have to reach out and see what we can find out.
Depending on the year of ECU that you are thinking of using, you may want to check out Project lambda, as they have cracked a lot of the 2001 and older NA and JDM ECU's.
Thanks for that question!
Yes
So I have a 2008 wrx automatic
Anti e couldnt be tebuilt because it was warped. The shop found a jdm 2.0 motor engine and I was swapped running with the stock turbo and transmission from the previous motor, would this work in the long run? Does the car need to be tuned? In less than a month I've had the check engine light come on. One was the MAF sensor sending codes of running too rich,and the most recent one was I believe a p0021 if I'm not mistaken it was Bank One, which was replaced previously. Are these codes coming up because the computer on the engine don't match up or because the car needs to be Tuned?
Thanks for your question. If I am understanding correctly, you put a JDM 2.0 liter engine in the car in place of the USDM 2.5 liter? If this is correct, then yes, you really should be tuned for the different displacement.
Hope that helps and Stay Tuned!
I’m in the same boat almost, how it go for you?? Please get back
What are some problems that are typically ran into when swapping a jdm ej205 non avcs motor into a usdm chassis
That is definitely the easiest one to work with, and should have the least amount of issues.

@@FlatironsTuning Thanks a ton!!
2002 usdm wrx wagon had a ej206 put in it but keep getting cels for all 4 cylinders misfiring. All cam gears bla bla is swapped. Do I need a jdm ecu to run it? Currently using my usdm one
Thanks for your question. the EJ206 was non-AVCS I believe. If that is correct, the pickups should be the same? But you may want to check the back of the LH intake cam gear and compare the pickup marks to a USDM WRX one. If they are different in location or count, that could be the issue.
Hope that helps and Stay Tuned!
@@FlatironsTuning thank you! I fuel pressure tested it and believe the fuel pump is actually bad. Will know more once I replace it.
I'm buying a half cut 2002 sti and im going to swap it into my 2006 forester xt. Any sugestions for ecu?
I'd say it would be worth sticking with the USDM ECU from your Forester. It keeps all of your tuning options open.
@@FlatironsTuning the forester has an auto trans will that make any difference?
@@FlatironsTuning and I also want to retain the avcs
@@Kado244 Nope. No difference.
@@Kado244 Given that, you would want to keep the USDM ECU, and then you will have to keep your USDM cams.
Just swap the ecu and tune the Japanese ecu. Gey a harness from Iwire and its plug and play if you're doing a full Japanese swap
This is what im doing in my bugeye. Avcs motor and ecu. Im not using the iwire harness, i believe the motor im getting has the factory avcs harness. I heard you have to repin/move a couple wires though. Still trying to find out which ones
So I did the swap and changed all the cams and know I’m getting a p0018 code
I installed ej205 avcs jdm to a usdm non avcs. Wont start seems crank and cam sensor have no voltage.. has any one had this before?
Ray Leal did you swap the crank pulley? And also the intake pulley? Also the camshaft sensor and the sensor above the crank pulley?
any thoughts on the ez30r ?
Sorry, no. We haven't played much with the 6 cylinder Subaru's...
@@FlatironsTuningCan similar concepts apply? Not regarding turbos and tuning of course. But things like emissions and cam sensors and ecu's?
4:06 Talking of access port, "AP will not work with Japanese ECU". How about AP compatibility with EUDM ECU?
There are Access Ports for each region of the world, and they will not work on other region ECU's. Cobb keeps the regions completely separate. So here in the US, we can only get US AP's, and the tuners software will only work on the US AP's, etc.
I hope that helps, and Stay Tuned!

As long as you swap usdm ej205 to JDM ej205 or ej207 it will work fairly easily?
Thanks for your question. As long as the engine you are swapping in is also non-AVCS, then the swap is fairly straight forward. However, especially in the case of the EJ207, you would want to make sure that the mapping will work with the new engine (double check the new compression ratio, cam profile, etc.).
Adding AVCS to the mix is where things really start to get complicated.
Hope that helps and Stay Tuned!
@@FlatironsTuning Thanks for the response! Really helpful information and helping me decide what direction to go... JDM vs rebuilt short or longblock. So many choices and a lot of opinions and info to confuse the situation.
@@rockytopridr7463 It definitely gets complicated fast. If there is anything else you run into, feel free to reach out to us through the Live Chat on our web-site too!
What is the easiest jdm motor to put in a 14 wrx
Thanks for your question. Since the car is single AVCS, I'd say a single AVCS JDM engine would be the most similar. As long as you address the cam issue and run the USDM ECU, that would be a pretty straight forward swap.
Hope that helps and Stay Tuned!
FlatironsTuning thanks a lot that helps a lot
How about fuel? Using american octaine fuels in your JDM engine.
Thanks for your question. Yes, that is definitely a factor. If you are running the JDM ECU, it may well be tuned for higher octane fuel than we have here, so you would definitely want to know that.
If you are getting the car tuned here, provided your tuner can get into the ECU, the octane isn't as much of an issue because the tune will compensate for any differences.
Thanks for watching and Stay Tuned!
Is avcs really that big of a deal? What do you goin from it?
Thanks for your question. AVCS allows the ECU to adjust the intake and exhaust cam overlap to make the engine have a wider range where it is operating efficiently. Basically, a bit better low end, mid range, and high end power. In short a wider power-band.
That being said, if your car didn't have it to begin with, it is not so beneficial that it is worth putting in all the effort to get it to work in most cases. You can have a very good powerband without it certainly.
Hope that helps, and Stay Tuned!
I've heard it's definitely worth it because you won't get the full power without it and it's basically a 20hp difference. Go to iwire for advice not this guy who doesn't seem to really know what he's talking about fully.
@flat iron tuning why do you say that? Everything ive been reading about on doing a jdm ej205 avcs swap into my bugeye saying its pretty much plug and play as long as you use the jdm harness and ecu. Pretty much just move 4 wires and retune. Everyone i heat about that did it says it was simple, they dont regret giving up their AP for it, only wish they did it sooner
what is that
Can you help with my issue? I did the JDM swap and the engine runs fine, but now the transmission doesn't shift properly. Do I need to reprogram my ECU?
Thanks for your question. Do you have a manual transmission or an automatic? I'm guessing Auto?
The short answer is that if you have a manual transmission, the engine swap should not make any difference.
Maybe reach out to us through Live Chat on our site (www.flatironstuning.com) and maybe we can help you track it down.
Hope that helps, and Stay Tuned!
If your running a 02-05 WRX and don’t have emissions, it’s pretty dang easy to drop a WRX EJ205AVCS in. Make sure you get the JDM AVCS ECU & either repin TGV’s and delete them or just buy the wiring kit from iWire or IA.
The twin scroll part is not true, the EJ20Y/X (Dual AVCS, from JDM legacy GT, etc...) that engine is a pain to swap into anything and make it work. The WRX EJ205AVCS is single scroll and easy if you’ll give up your Cobb and go carberry for tuning.
I’m Using a 04 usdm WRX harness with added in AVCS wiring, with factory JDM ECU. Didn’t have to change anything else, it’s common folks tail that you have to swap anything else to make it work with the WRX 205AVCS.
Engine is nicer to drive compared to a USDM 205 and also sad to see it not said the jdm engines are 9:0:1 compression.
This guy doesn't seem to fully know what he's talking about. From what I've learned from iwire and doing research, an avcs ej is probably the easiest swap to do. This guy seems to be giving false information for some reason.
I put a JDM 03 WRX EJ20 in my USDM 03 WRX, and the only codes I’m getting if for the TGV. Should I just delete the code so it doesn’t throw it anymore? Because I read that it doesn’t have a tgv. There’s no sensors on the intake manifold and they’re sealed off
