Just an update here. The swap went well, no issues that I know of. Turbo rebuilt by JPM, what a wealth of Subaru info he is. If you guys haven't talked to him, you are missing out.

I am at 200 miles. 300 till clutch is fully broken in. I will know more then

He followed up with "this is ej25 not ej20" So I am hoping this is what I need...

Any input on this clutch and flywheel ?

seanyb505:

I am looking at replacing the flywheel and bolts for sure. i have seen the Exedy's around.

Infosecdad:

Thanks for the info. I have asked him the question, we will see what he comes back with. as for the tranny, I figured I would sell it or something, it was a package deal so I just bought it that way.

If this is a 2.0L and I end up with it...how boned am I ?

Edit: from the Ebay seller "This is 2.5L thats why more expensive cylinder block has ej25 marking not ej20"

Thank you very much for taking the time to respond.

I basically found one on ebay and had it shipped. I don't have the motor in hand yet.

The posting stated it was an EJ255 2.5l. The exact reason I purchased it. I will have to determine the rest of that information once I get it.

There is a tuner about 2 hours from me, I will be sure to take it in.

EDIT: Also since the motor is coming out, I am assuming it's time to put in a new clutch...any suggestions for a daily driver ?

Hello all,

I have scoured many a forum and many a google search has been had. I have seen many posts here about swapping "this" engine for "that" engine but I have learned very little. I apologize I am not very smart.

So my questions are...

I have an 05 LGT limited 5MT.

The kid that owned the car before me did all kinds of unknow things to this car I am sure. Long story short, I am getting a missfire code. My mechanic thinks it's the heads. Fast forward a few weeks and I purchased a full engine as this one had 180K+ on it. I purchased a JDM "2005-2005 Subaru Impreza wrx EJ255 2.5L Turbo Engine SINGLE AVCS Forester EJ255".

I assume I need to take the spark/fuel/air system off the current motor and move it to the "new" motor ? If I do this, can I keep the current ECU ? I have read many a post about having to accommodate for the AVCS system, but I currently (think) I have a single...and I am putting a single in...is that straight forward enough ?

I am going to keep the and maybe rebuild the current hardware, maybe add some power. Who do you trust to rebuild the heads/engine ?

I am sure I will have more stupid questions I am sure...thank you for your time.

An important difference between JDM Subaru motors and USDM motors are the cam sensors and the placement of those sensors as well. JDM cam sensor sends a sine wave and USDM is hall effect. You could swap the USDM cams in, but the placement of the sensor will need to be modified in the heads using a Dremel of some sort to move the sensor directly over the trigger.

This sounds like it would better left to a pro. I would hate to purchase 8k worth of parts to mess this up...

Thank you, I have looked at your link...I will be putting together a project soon I think.

edit: it might be easy to order those things. Having the knowledge to put a motor together on the other hand, That's what has me nervous right now...

I can be of no help here. I am curious about some of this as well. Not exactly your specific case, but I am interested in a JDM engine swap into a USDM car. I believe from what I have found the ECU will need adjusted or even swapped.

I will be watching this thread and hope you (and I by proxy) find the answers you need.
