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 ? https://www.autohausaz.com/pn/FJK1001FW

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.

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

Thanks for all the feedback. I will keep you guys up to date on what I do here.

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.

I sent him an email based on his page. Thanks again Max!

Thank you for the reply Max. I will look at this information when I get back in town this weekend.

I am in the market for a new motor as well, let me know what you go with or find out please...
