I'm working with an engine importer on an EJ205 (w/acvs) and they told me they could sell me this ecu pictured here which DID NOT come with this engine. To me this looks like an aftermarket tuned ecu with the giant Zero Sports sticker on it. That has me concerned.
If it is aftermarket tuned, can I have it returned and use it with my EJ205? The seller also had an auto ecu (swapping the engine into a 5 speed USDM wagon) or do I look for another ecu elsewhere? |

I did the exact same swap with one code. P1507 . I took the Idle air control valve apart . I found would looked like carbon build up in it. Cleaned it, put it back togther and code was gone . Those engine sit for a while before being sold i guess.

Can someone point me in the right direction. Doing a JDM ej205 w/ AVCS into an 04 WRX. I have the JDM ECU and wiring harness. Which wires can I use to activate the AVCS? Is it easier to just buy the wire kit?
I'm doing intake, equal length headers, uppipe and downpipe. Replaced timing belt, water pump, valve cover gaskets, spark plugs, upgraded sti oil pan and pick up. Anything else? Car will be tuned once I get it running. Thanks |

JDM swap- no crank issue
hey guys, this is my first post on nasioc ever so hopefully I'm writing in the right place. I just swapped in a JDM ej205 w/AVCS into my '02 WRX w/oAVCS. I left all JDM accessories, intake, cam gears on. I also swapped ECM's so I can maintain whatever JDM specs with all the JDM things. To my surprise everything hooked up except for the AC compressor (and obviously AVCS). I go to start it up for the first time and I run into a no crank/no start issue. of course it HAS to be electrical! sometimes it will crank over, usually it wont...So I've been troubleshooting over the last couple days. I have a brand new battery, my starter has been tested, it's good Ive even swapped into another starter, and scrubbed all of the surfaces to ensure a ground connection. I have good voltage all the way around from the ground to the positive, and I have power running to the solenoid from the starter switch. I've also connected a wire straight from the solenoid to the battery to bypass the whole ignition system. I've also tried swapping the ECM back to the USDM one. when I turn the key or connect the wires there's a loud clicking and the fuel pump I'm stuck and frustrated, I just want to take this thing for a drive already! (it sat in agarage since last year so I could save up the money for this swap.) Oh, and yes the JDM engine was pressure tested and it does turn over by hand. Any suggestions would be much appreciated. Or heck a phonecall or text would be great! 8479753480

JDM swap- no crank issue
Tone, thanks for the reply. I see where you thought so seeing that I ruled out the ignition system with a straight wire. I also have full voltage on the positive end on the starter, and every point I tested on the starter. however I have swapped in 3 separate starters that I know work (special thanks to That One Guy!), and all of them work with jumper cables and a screwdriver.
I looked at the 12lb(?) XTD flywheel I have on there. I had the same flywheel on prior to the jdm swap and it had no problem turning over and running. I also managed to get the starter to turn over a couple times. the one discrepancy that I saw was some chipping on the paint in front of the flywheel teeth. that indicates to me that the starter gear is shooting out to the flywheel but not turning. the scientific process does not apply and I am officially in a twilight zone. any other other tips or tricks? on 26DEC, I am pulling the motor back out. FML. at that point I will mount my old tranny up to the engine, mount the starter and jump it to see if it will turn over.Im also assessing to see if this aftermarket flywheel may be the wrong one for my 5 speed tranny. any thoughts or ideas? update: I pulled the motor mounted up my old tranny and starter to jumper cables. it turned over immediately. I only had a bad ground to the starter despite the attempts to fix that, and despite measuring 12.6? volts all the way around. unfortunately, I got the engine back in and started with immediate knocking. I returned the engine, reinstalled another jdm engine and it runs ok. I notice the occasional misfire, and it smokes like a freight train, I suspect it's burning oil. the warranty period runs out in 2 more weeks, so I need to make a decision and fast on what I need to do. for now, I'm going to run it softly and see if I just need to burn up some carbon, also I'm going to swap in the USDM timing gears, and reinstall the USDM ECM. I'm using the USDM intake so I suspect the TGVs aren't wired up with the JDM ECM. I have no clue how to tune, and any advice would be appreciated about the smoking oil smelling exhaust fumes. ( I have the catless uppipe until I can replace the EGT probe on the USDM uppipe.) my phone number is 847-975-3480. Last edited by jonpers172; 01-22-2016 at 08:06 PM.

Vehicle:2003 wrx sonic yellow |
I'm relatively new so I hope I'm posting in the right area and this hasn't been covered but I haven't seen it exactly anywhere. I have a motor on the way for my 03 wrx. Its an ej205, and after calling dealship they told me based on the serial number it's a 2.5l shortblock legacy gt sti wrx. My question is based on this can anyone give any insight as to what I might need to change during the swap. I will not be hooking up avcs so using stock ecu, I understand I have to change over the IM and EM for sensors to read right, what about the cam gear? I'm also concerned about compression. Any insight would be amazing and thanks for the help
Update: For anyone thinking about doing this swap and considering where to get the motor I got mine from jdmracingmotors.com they change the cam gear and crank gear to usdm so that you do not have to change them yourself. I wasn't overly thrilled about having to take them off and change them so if you're looking for a more plug and play motor swap experience that company might be the way to go.

Need swap too

I also have an 02 with a motor in pieces. So if I get this right, an import engine will work fine as long as I retain intake, harness, and perhaps the pulleys? Is it this easy? Mike (MA) |

Anything pre 2000 motor needs to swap over intake and harness, some pulleys. If you get the right JDM wrx motor that has AVCS everything will be plug and play. No changing anything and it will work. |

I swapped an jdm ej205 into my bugeye did not switch a single thing, simple plug and play, it fired right up the first try...2 years later still running strong....
i have not hooked up the avcs yet but do have a full uncut harness to harvest the wires from and a jdm ecu. i bought my motor from dallasjdmmotors.com i got complete motor with a harness and ecu included! I called them and spoke with them after finding them on ebay! i highly recommend replacing the up pipe with an aftermarket one to remove the cat(this will save your motor from immanent destruction), also replace any and all gaskets, timing belt and water pump while the motor is out! along with new plugs. check all vacuum lines and any rubber lines on the motor, if you even have a doubt about them replace them!

Even bewteen 99-00 subaru GT engines which are EJ205 the crank and cam sensor are identicle. They are different color sensors but they are interchangable. How do i know this because i have swapped cam and crank sensors from 03 jdm wrx ej205 into a EDM/JDM 99 GT EJ205 and car ran perfect. |

Hey, So I have a 02 wrx and I'm swapping a 04 EJ205 w/AVCS into it. We did the whole swap put the motor in using the old 02 ECU and harness. The motor turned over no problem but after driving down the street for about 1 minute it started violently rattling. Any suggestions as what I could change or swap in from old motor? Also have JDM ECU and wiring harness if necassary

ej205 in 06 baja
I'm considering buying a Ej205 to replace the 2.5 turbo that needs a valve job in my 06' baja. I've read that if I swap my manifolds and sensors that the 2L longblock will run just fine with the 2.5 ancillery items without throwing codes. Does this sound right?

JDM 205 with single AVCS-maybe.
But why put another used "unknown" engine into the equation ????? Fix the heads. |

jdm ej205 not starting
I recently swapped a jdm ej205 non avcs and to my understanding it is a version 4. I was told to swap the cam gear, crank gear and crank sensor and it should start and now when I turn it over it sounds like it wants to start (making popping noises out the exhaust) but just wont fire up. The car has compression, fuel, and spark. Any suggestions? Thanks

Any exact answers???
I've been reading and haven't got an exact answer. So my 03 has a blown engine. And I would like a long block. Jdm is the better price. But will it actually work correctly. I have no problem getting a tune. My tuner is just 4 hours away so it will be a mission. Looks as tho jdm has the non avcs and avcs engines. Both 9:1 (no jdm has 8:1?) so can I take the avcs engine and swap my cams from my usdm motor? Block off the avcs completely? And is it the head that bumps compression? Rods? Pistons? Maybe the short block is different? Can you swap your heads on to the jdm short block? This would be my first ej motor experience. I have the fa20dit so that's what I'm familiar with. Any help is appreciated
