Thanks for the shout out! Just a heads up that we sell the kit with the wiring for the sensors and solenoids because we don't want to hijack TGV wiring due to the EPA enforcement. This method of repurposing shown here definitely works but we recommend running fresh wire for both so you don't have to worry about it. This is probably more of an issue with the JDM 205s with TGVs than the JDM 207s that do not.
More shout outs to come, hope you don’t mind. Yes Ive used your avcs kit a few times.Your wiring solutions are the best in the biz. Most the 205’s I do, i will just put the usdm 205 intake manifold on in entirety and supplement your bulk head harness and remove the avcs wires/plugs from the jdm intake mani. Most the 205’s I get end up being drive by wire 16bit so the harness otherwise is a no go in the drive by cable cars. Keep up the great work and support for the subaru community!
Great video! I am about to swap a v7 into a 2003 USDM WRX. Do you know of any good written out guides? Love the video, but I prefer something written when I am working. Also, when ordering parts like the valve cover gaskets and timing belt can you just order stuff for a USDM WRX? Thanks in advance!
@@calebcartmell7855 an upgraded fuel pump is 100% not needed. But doesn’t hurt i guess. As for a written how to, i feel there is certainly some on the naisoc forum. All the gaskets are the same as usdm ej205 with the exception of: Valve cover gaskets (jdm v7-v9 205/207) can be ordered on ebay Intake cam gear seals (06-14 ej255)
How did you pass emissions on the jdm ecu, asking because I can’t seem to figure that out. Since the cobb AP wouldn’t work with the ecu, should I go open source? I just want the car to pass emissions without having to buy a different ecu just so the computer can read it. Any advice/ suggestions?
@@GusDiaz-t8j In Ontario, Canada. they pass without issue as long as no CEL on, they were able to pass my personal car with jdm ecu no problem with hooking it up. Any scanner will/should read a jdm ecu without issue. Unless you live somewhere with some sort of extra extra step in emissions testing
How did you know what ecu to get with the engine? Im trying to order a replacement because the one i have in my 05 wrx with the ej207 but having some issues finding the right one any help would be great
You could use any drive by cable, manual transmission, 16bit avcs ecu. Unless your not planning on getting a tune. Then id recommend ecu exactly for your version of 207
The pass side engine harness stays the same. But the pass side with respect to car side to ecu, does get additional wires which would come in a bulk head kit and or you add in yourself.
Should the v7 ecu have a 6L on it? Mine came with a 4L and I'm just hoping it's the right one. I've seen others for sale online come with a 4L too though.
They can range in codes. I have a loose one at my shop. Cant recall code on it. But there are a couple jdm v7 type 205/207 ecu’s available. All work the same in the end as long as 16bit, dbc, avcs and manual!
Do you NEED to swap intakes from usdm 207? If it's a jdm engine running on a jdm ecu..? Have a 205 working avcs swapped. Could a jdm 207 plug and play 100%? Referencing my first question.
Running jdm ecu for avcs. You can leave on jdm 205 intake mani as long as it is drive by cable. But a 207 intake manifold will also plug and play on the jdm 205 and work without issue as long as it is also drive by cable (most early ones are)
I'm just now seeing I watched and commented your video already. Thanks for guidance. I went JDM 205, us mani, V7JDM ECU & iwire bulkhead/intake. with a wicked tune! @@TheSubieSanctuary
Awesome that your in Ontario, I'm familiar with engine swaps but this would be my first with a subaru. Mine Is a 2004 wrx, wanting to STI swap it with same motor you guys used. What do I need to search online to understand the wiring part you guys did and as to why. Or do you have forum for it
The V7 is the most stout of the bunch. The v8/v9 cost alot of more and then gets into the need for twinscroll downpipe. The customers do what they want i guess but it’s probably the cost difference and the required hard to find twin scroll DP. IMO the v7 due to standard fit turbo leaves more possibilities for turbo upgrade where as the twin scroll after market turbos are pricey new and rare to find used
Sounds like cyl 4 is getting tired. Typically the piston rings/ring lands start to fail/crack and drop compression. Its a quick decline from there. Could be months
In this swap we used the matching jdm ecu. So no you definitely would not want to change the cams. I also have how to video’s on swapping without using the jdm ecu in which we still dont replace the cam shaft or gears. Hope that helps
You have more info about the complete AVCS wiring? I am actually trying to reverse to order to get my USDM TGV work again with the USDM harness. I want to see how's the harness look like before modded for AVCS wiring. Thanks!
Question: why would you want tgv’s? They are a just a problem waiting to happen. Id recommend deleting them. But if you choose to keep them then i can email you the iwire link to the wiring and you can just reverse it
@@TheSubieSanctuary I know it's sound stupid. I am doing it to for stock condition for DMV registration. It will be temporary condition, I will go back to AVCS and JDM ECU afterward.
They turning it down because its a massive job. To be successful you ideally need whole sti as a parts car as its a lot more then just the motor that youll need. If you have the motor already then you can talk to iwire about getting the merge harness.
@@TheSubieSanctuary do you have the exact number difference? I just bought a 207 swapped 04 wagon and would love to know how much power it’s putting out
Yes this will work with an auto wrx. But you will need a jdm ej205 16 bit ecu from an auto wrx. Even though its a “wrx” ecu it will still run the ej207 just the same. However like most swap you will need a tune. Cobb does not support jdm, you will need an opensource tune.
Any of the 207’s will do be capable, thats a lot of power on these old engines though. But with fuel lines, rails and big injectors and turbo the motor will make the desired power
Ej207 is a few weeks from going in to my 05 wrx! Nice video man!
Edit: its in and it is great!

LOL this is *exactly* what I'm doing, but with a 205. Thanks for providing the engine, my friend!
This makes me feel much better about just getting the jdm motor. I did more to get my “bolt in” h22a swap into my accord. Thanks for the video.

Is it a lot more shifting with the shorter gears? Are do you even notice a difference?
Depends on your track. I went from 4.44 in a car to 5.11 and it was more shifting and kinda had to re learn all the local tracks

Iwire sells the wiring side of it.
Ej207 swap into 02-05 wrx should do!
I noticed you do a lot of v7 and not V8/9, what's the reason?

Have a 05 wrx w a compression of
Cylinder 1 to 4 in order
150
132
Cylinder 3 : 145
135 cylinder 4
Thoughts ? Mechanic said needs a new motor soon
Sounds like cyl 4 is getting tired. Typically the piston rings/ring lands start to fail/crack and drop compression. Its a quick decline from there. Could be months
roughly how long does it take to do by yourself/with a mate?
With a friend it could be done in a day
2 days by yourself
Looking at doing this in my 02. I can’t seem to find any info on it but do you know if you have to change out the nps polarity?
Not that i no of with the v7
Would u have to change cams for this swap?
In this swap we used the matching jdm ecu. So no you definitely would not want to change the cams.

I hear ya there! Cant you just turn off the tgv codes? Then leave tgvs in place to give the appearance of them being there?
@@TheSubieSanctuary well, CA DMV check ECU now, so they will fail you if you delete the code.
Ah yes 😭 the most hardcore state when it comes to emissions and inspections
Im trying to swap my non turbo motor to an sti motor is it possible alot of mechanics are turning me down SMH how can I make this possible
They turning it down because its a massive job. To be successful you ideally need whole sti as a parts car as its a lot more then just the motor that youll need. If you have the motor already then you can talk to iwire about getting the merge harness.
Is there a horsepower and torque difference between the ej207 and the ej205?
Yes, 207 has more torque and hp

Does the wrx the same automatic car

What ej207 Version you Recommended v7/v8/9/v10??
V7 is the best stock block, V8/V9 is the funnest stock turbo setups.
They are all good though motors though
@@TheSubieSanctuary so im about to buy full ej207 what you Recommended v7? My goal is 400 450 hp
