Thanks for the info...I'd bet it's the exact same as US. But there are a few other variants of TD04 that might have been used, such as the TD04HL-19T (a turbo I'd like to have!). Next, hopefully someone w/the JDM EJ205 from a 5-speed / Manual-equipped car will reply. TD

Hoping somebody can help me out with the following. My nephew has just ordered a 2000 JDM Subaru Legacy B4 from an importer here in Canada. It has a 2L twin turbo engine. So it would be a EJ20? What is the proper designation of what model of engine that it has? What is the correct oil filter for this engine here in North America? Thanks in advance for your help!

jdm ej 205 swap
I recently ordered a JDM ej205 with avcs, intercooler, and mafs from japan direct in Canada. motor has 51k on it not sure what year. to do the swap all i did was remove all the wiring that went to fuse box alternator etc. dropped it into my stock 02 wrx it bolted right in with no issues timing looked new along with the other belts plugged everything in, adjusted the clutch, and had to replace the iacv. been driving it for 3 days now with no problems or cels. don't know if this helps anyone but if you have any questions feel free to ask.

I changed the IAVC because when I did first start it threw a CEL for the IAVC so I took it off and it looked pretty dirty.so I took the one off the motor I was replacing cleaned it up and put it on. started it and she hasn't thrown a code since. The throttle is cables. Timing, I did not have to change anything. and AVCS, I honestly don't know i was reading threads today trying to determine what people meant by AVCS wiring and having to order a different harness? forgive me I'm pretty new to really working on subi motors i plan on using the motor i pulled to learn more about the motor by doing a rebuild. It was hard to get a pic of the whole number in one frame with it installed but here are the numbers as I can see them EJ205DX3BE-1BA 068026 EF10 I was also reading that some JDM motors are a 9:1 compression but I couldn't find out how to find out. I also plan on getting a tune done but was looking for exhaust first. hope this helps and again plz forgive my newbness. |

^^Thanks for the info.
I believe there are 3 plugs for the harness(es) that run from the engine to behind the battery. You reused your original harness for the AC and Alternator, and used the two other JDM harnesses for the CoP (coil on plug), etc. , correct? "ECU wires"...you did NOT run the harness wires to the ECU in the car, correct? There should be wiring for the AVCS on the JDM engine. Since they DON'T exist in the harness to the ECU from by the battery of your car, you'll need to buy the http://www.iaperformance.com/ harness that'll run from the AVCS connectors on the engine back thru the car's firewall to the ECU to run the AVCS. Yeah...you'll need a tune if it's indeed 9:1 CR. I don't know how to tell. Thanks again |

yes, there are 3 main plugs coming off the motor, but two are on the driver side behind the battery and one is on the passenger side. there are two other plugs for the passenger side but one is an exhaust temperature sensor the other is a front o2 sensor.
Correct, I used my a/c, alternator and fuse relay box and wires, but kept the CoP and the main harness with the three plugs that came with the motor. The only wires I plugged in were the main wires; the two on driver side behind battery, and the one on the pass side, along with the temp sensor and o2 sensor. so no i didn't run any wires straight to the ecu. I think the wiring for the avcs was on the fuse/relay box harness that i didn't use. i took pics but am new to this sight and don't know how to post them. Sorry for any confusion. |

Cool - thanks for clarifying.
Pics can be UPloaded (hosted) to a photo sharing site (free) such as flickr. Then copy the URL from the site and paste into the image (mountain/moon) icon. Search online for better instructions, but I don't think pics are necessary in this case. td |

Hi,
Im currently about to drop in a v7 JDM ej20 with AVCS into my 2003 v7 usdm wrx. AVCS will not be activated. Emissions are not an issue for me, so the intake manifold from the JDM motor will be retained. After it is placed in the car I will have a dyno tune by Cobb. From what I have read, it seems that v7 motors will run properly without switching cam gears and the main crank sprocket? There seems to be a lot of confusion when people post without clarifying which generation motor they have. My question is, if the JDM engine is from the same generation as the USDM, all that is needed is to plug the wiring harness in at the proper junctions (brown & grey near the battery)? |

My engine was a 2002-2003 JDM EJ205 that came with a JDM STI ECU and I just dropped it in, plugged the harnesses together and wired the AVCS in with the IAPerformance kit and then tuned it with Steve at IAPerformance. Very easy to do and no swapping cams or anything. Complete plug and play. You don't have to wire the AVCS at all but why not? It's an extra $200 but super easy to do if your engine came with the JDM ECU. Just keep the USDM one and plug it in when you need to do emissions or smog and get the tune ported from the JDM one to it so you can safely cruise with the USDM one if you need to drive far to get to an emissions/smog place.
The only issue I had was with my ECU not being in the ROM Raider system cause it was a rare option, Automatic JDM STI. Just unlucky but after I got around that issue with Steve it was easy. I ran out of time to finish the tune but I'll have 2 weeks off that I can knock it out and finish it. Its an easy swap and a bit nerve wrecking while waiting to see what condition the motor you get is in but I was satisfied with Dallas JDM |

Hello all,
I am currently trying to drop in a JDM ej205 engine with no avcs into my 2005 WRX. Bought the engine off of ebay, shipped from Canada but assuming it was imported from Japan. Went into the shop today to switch out the turbo and injectors that I was going to put on my old USDM ej20 engine and noticed that the JDM ej205 had the yellow sidedeed injectors? Didn't notice anything else that was completely different. Both engines have been stamped with "ej20". Still confused with the yellow STI style side feed injectors. Is it just a matter of switching over the fuel rails from my wrx? Is the engine still plug and play after that? Would it be a better route to return the injectors I had bought for my wrx and buy larger sidefeed injectors? If I do go that route would it still be plug and play and just in need of a tune? Thanks |

Hi,
I'd just swap the Intake Manifold (IM). Injectors go into the TGV's and I'm not sure if the TGV's are swappable between the Top-feed and Side-feed and still fit the US IM. And are you sure it HAS TGV's? This ONE on ebay has side-feed yellows too. Depending on the year of the JDM 205, those 'might' be the older 480cc injectors ( I doubt it), which were NOT interchangeable w/the US STi side-feeds injectors. GL, Td |

If those JDM side-feeds ARE 440cc or 480cc the stock WRX ECU should be OK? But as a reference, JDM STi PINKS (565cc) and USA STi/WRX Dark Blues (565cc) are NOT the same. Cobb and others say to NOT interchange when using their OTS maps...due to latency, I believe. BUT You can use most any injector size (and maybe style - top vs side) ONLY IF YOU GET A TUNE. The problem I see here is that you don't know exactly what injector you have on the JDM. If you pull one, take a pic and note the P/N there may be help on here / online. I still vote for swapping IM's. .....and replace your turbo inlet hose while you're @ it. Read thru THIS post too.....probably covered on here, but didn't look.

Rumor is the CR is 9:1 on the JDM EJ205, but AVCS or Non-AVCS? I don't know. Get a conservative tune and go from there.

Got a reply on a set of JDM 205 SIDE-feed injectors on Ebay:
Subaru Impreza WRX JDM EJ205 Side Feed Fuel Injectors w/ Rails OEM 02 03 04 05 I wouldn't call this definitive, but worth noting: Quote:

Talking to a mechanic Monday and seeing what we can do then. I think 444cc sounds about right. Wondering about switching over fuel rails from old wrx engine and going with top feed? Ideas?

Sorry I was a little confused I thought you meant getting an STI IM to match the side-feed injectors! So switching over my wrx IM and fuel rails, correct? Wondering if I should port the TGV's and IM while it's off... The bigger injectors I have are top feed to replace old WRX injectors

Jdm Ej205 Into Usdm 03 Wrx?
For anyone wondering...another option is buy an ej20g long block and transfer the ej205 heads, manifolds, accessories and all timing components to the ej20g shortblock using cometic 1.3mm gaskets and you'll have a BEAST motor for the price. My jdm ej205 blew up after 6k miles...still an open deck motor that cant withstand a good beating, while my ej20g is closed deck and comes with forged pistons and sti rods

^To clarify, not all the EJ20G's are closed-deck. Only the very early years, from everything I've read, and not that common any more.....and the forged pistons depend on the year.
List HERE. EJ20G Open (left) vs. closed: |
