JDM swap
Hey guys new to this forum I have been apart of several other Subie forums I like this one! seems like a bunch off good guys!
Anyway if someone could give some input that be awesome I will post all updates through the process to help future members . I have an 08 WRX ..an engine supplier me and my partner have been getting engines from for a while gave us a JDM 2.0 to put in the 08 wrx to replace the 2.5 ... Are there any issues to worry about? I want to retain the USDM ECU not sure if the engine has AVCS or not does this matter? please help if you can thank guys!! |
If you're looking to do a complete engine swap I would imagine you will need the original loom from the donor car and the original loom from the USDM car receiving the engine.
You'll need to pull the ECU and engine loom from the donor car's loom, remove the engine loom from the USDM car's loom and then splice in the engine loom and ECU from the donor car in to the remaining USDM body loom. |
I think you will run into a fair few issues tbh.
Do you have the complete engine or bottom end only? Have a look at this thread for potential issues, it's obviously not the same engine/cars in question but you'd probably run into similar problems: http://bbs.22b.com/forums/showthread...into-2006-WRX& |
Hey guys thanks for the input i have a complete engine with harness as well as donor , apparently the year model i have is a tricky one.. an in (between) if you will. It will use single AVCS like the USDM vehicle has currently the engine was matched side by side at the supplier. any of this sound familiar to anyone?

You have not stated what your 2.0 engine is sourced from, year etc saying its a tricky one is vague.
If your 2.0 has 2 pin cam sensors, the WRX 08 has 3 pin & the cams also have very different trigger patterns, easy to overcome with an aftermarket ecu but not on the std oe one. |

MOTORS thanks for your response.. what i meant by the year is a tricky one was the AVCS im sure youve seen in a lot of post people say all 08+ have dual AVCS this wasn't the case for my car that's stamped 09/07 in the door jam...
the 2.5 i pulled out is single AVCS I have a single AVCS JDM EJ20 not a 100% on the year but i think its from an 06 i can post a pic of it if you think that will help you identify it.. thanks for your help |

The WRX 2.5 Hatches have always been single AVC's, the STI's dual AVC's 2.5 or 2.0 JDM, your 06 will be as you say single AVC's, its the cams & trigger patterns as I mentioned will be your problem with the ECU, the biggest change is the trigger that picks up on the back of the l/h inlet gear on your 2.0, that is not there on your 2.5, instead it has a missing trigger slot on the inlet cam to know its cam position in relation to the crank, with 3 wire sensor not 2, the sensors are different to each other & not interchangeable without machine work, all doable on an aftermarket ecu, but not an oe one.

Yeah there are people all over claiming the WRX 08+ are all dual AVCS.. Thanks MOTORS for the help, if I post a picture of the engine do you think you could help me correctly identify it? Also does it matter what year JDM EJ20 it is? or will I run into the issue you explained above with all JDM EJ20's? despite year..

You will run into the same problem with all 2.0 single avc's engines, with the swop you are trying to do, you would be better sorting your current 2.5.

What about the engine management? are you talking about using like AEM or something? I can return the engine and nothing against your knowledge you know your stuff but hasn't this been done? Im guessing with a stand alone ECU?

Yes it has been done, I have done a few, but you will not do it on your ECU, as mentioned before, its not a straight forward swop, look at your two engines & compare the differences its staring at you, but you can put the 2.5 triggers into the 2.0 heads with a modifications to the head fixing, & bolt position, then you will need to remove a specific trigger lug from the inlet cam to give its position relative to the crank, as you have no l/h cam pulley trigger on the 2.5.
The few you did what did you use for engine management or did you do the mod work? |
