Lol catted downpipe it is then! But I believe my downpipe is fine so if I can save money on that I’ll end up sticking with what I have.

Will do! Thanks. Catless downpipe from 1320 on eBay is about $200 shipped.

Thanks for the responses! I think the AP the seller has is V3 but I asked him to confirm. Either way I plan on getting another tune just so I don't burst my transmission. Will find out what a safe PSI is that would be best for daily driving. Alright I will look into downpipes too. Yes, long block, short block, heads, manifolds/headers, up-pipe, etc will all transfer over from sellers car to my car. Sellers car is MT mine is AT.

Yes I know I will not have the same exact numbers. I also agree I would need a tune. Not asking what hardware should and should not be transferred, just asking what do I need to do to get it working on an auto transmission which I got my answer. The rest the shop will take care of, I will not be doing the swap myself. I will be replacing the entire motor--heads, blocks, intake manifold, etc with that newer rebuilt motor. It will be a straight drop-in minus changing out the flex plate (according to the shop and rhino6303).

Thanks for the response; Yes I will be getting a tune no matter what since my ECM is different.

Thanks for the response. He is selling me everything with the engine--turbo, upipe, intake, intake manifold, exhaust manifold, etc (minus catless downpipe since I have automatic) the full nine yards to make it a straight drop-in with no extra work necessary, besides the flex plate.

Alright thanks. I’ll buy the COBB from him too since he’s selling it cheaper than a new one and get a tune for it. VB? Valve body? Mine is stock. Not sure about his.

Thanks for the comment. I don’t drive very hard, occasionally I like to drive it like it I stole it. But since it’s my daily I don’t beat on it very much. I want more reliability than speed. I was thinking though since it’s tuned (because of vf52) via cobb I could buy the motor and accessport but get another tune for it that isn’t as powerful. Thoughts on that?

Awesome!! Thanks for the response. I wanted to also ask he says it’s making roughly 330whp/330wtq.. and my 5eat has about 190k miles on it. Not sure if it will hold up okay with that much torque? Thanks again.

Hi all, Some know my engine is knocking and I need to get it replaced..so here it goes: This may be a stupid question, forgive me, but I found a guy selling a rebuilt ej255 with 10k miles on the engine and a bunch of goodies. The only thing is it is paired with a manual transmission. I will be replacing the ENTIRE engine-- long block, short block, head, turbo, manifolds, etc. I just wanted to know would the motor also work with the 5EAT or would I have swap things out to make is compatible? Thank you.

Issue resolved. See duplicate thread: https://legacygt.com/forums/showthread.php/need-help-2009-legacy-282633.html

Thanks for the response. I found out I am getting some money from school which will be enough to cover a newer EJ20X motor. I know which route I am going to go with. I am going to sell off stuff from the other motor that I do not need and try to recoup as much money as possible. Will also replace or rebuild turbo (if it turns out to be fine). Hopefully nothing else is damaged and I can get away with just replacing the head and block.

Meant to say if I just replaced the ej20x with another ej20x and not do any work to the "new" one. They have done some great tuning work from what their customers said as I reached out to some. Sadly not many to have legacies. I heard that church automotive which isn't too far from me (granted my car is working by then) does some great tuning as well. A bunch of people recommend me to them.

Ugh I hope I do not need a Cobb AP, that will cost almost as much as the engine lol. I do have a OBD2 to USB as I bought a while ago. There is one shop my friend (he has a newer WRX) recommend me that will do a free e-tune if I buy the Cobb AP off them. Promo is till July. Here are some parts I was finally able to find: Bearings: https://www.ebay.com/itm/King-STD-Conrod-Bearings-suits-Subaru-EJ20X-EJ20Y-Liberty/303188144853 Rings: https://www.ebay.com/itm/Hastings-Piston-Rings-Chrome-STD-suits-Subaru-EJ20X-EJ20Y-DOHC-16-Valve-Libert/293127710223 Head Gasket set: https://www.ebay.com/itm/JDM-Subaru-Legacy-BL5-BP5-EJ20T-2-pcs-Genuine-EJ204-EJ20Y-EJ20X-Head-Gaskets/122669944969 Now the only thing I am unsure about is if the Bearings and Rings are for the bone stock EJ20X or if they are for modified head/block. I did email the seller, awaiting a response.

Thanks for the response. I don’t really remember what the smell is like but I will start the car up today or tomorrow and try to figure out what kind of smell it’s close to. Ah I see, but a blown turbo sending bits into the engine could still very much damage the engine correct? I will just have the shop that did my tune do the full inspection and see what they say. I’ll also take another video from the top of the engine. Edit: Possibly a dumb question, do I need to get another ECU when I get the new engine since I have a tune on it or will it erase itself once I put the new block and head in?

—Bump— Can’t find anything on the ej20x rebuild kit. Can anyone chime in and tell me if piston rings from a USDM EJ20 motor would work? I can not seem to find much info, stuck in a bind. Thanks! Edit: I found this website that sells parts for the Ej20x motor: https://www.precisionintl.com/ just not sure if they ship internationally.

Holy moly thank you for the info! I am leaning towards just spending the money on the motor only and then salvage and sell whatever I can from my existing motor and sell whatever I do not need from the new motor. I have not, I have my tools at my friends home who lives about an hour or so from me and I don't really have a way to get to him at the moment.

Thank you for this informational comment! I will take this under advisement. Just curious to know what a good upgrade would cost for a rod set? I was thinking, to get some money back, when the old motor is out I will have my friend disassemble it and possible rebuild (depending on how the block and head are). If it ends up being too much I might just sell it as it. Best way to recoup some money. I will also sell parts off the newer motor that I do not need such as the intake manifold, turbo, etc. I know it is a lot of money upfront (for a student such as me) but not much else can be done. I have updated the links! Please let me know if it works now.

Thanks for this. I posted a question on that thread, any insight would help greatly. Thanks!!

If I was to rebuild my current motor, I know I would need the crank and rods, but I am not sure where to get them from. There is not much information on the Ej20x motor and I do not want to end up getting the wrong part(s) for it. Anyone know of any place that could help me? Thank you!!

Thanks for the response. I did just notice the knocking noise. I lost power a couple weeks back but never drove it after that. However it is my only car and I need it to get back on the road ASAP. I don’t know if it can be saved without opening it up, that’s my only worry. It would be a big loss of time to me. I have a very hectic summer session ahead of me. Not really sure what to do.

Hi all, I just found out my Legacy's engine is out of commission. Long story short: I got my car reflashed a couple weeks back and decided to get a burble tune (messed with the fuel map) as well. The car was running fine until it was not. It starts up just fine during cold start but it would struggle to start when the car is warm. Come to find out this morning, according to these videos, I have rod knock (yay!). https://drive.google.com/open?id=1cOd-4qKYd4TdQOZFWh3lWCsCAiWqLxa8 https://drive.google.com/open?id=1kLBkcjWGMiSV9U8lwn4IJKopAgPL5hqk It is an Ej20x motor, because back in 2018 I had to get the motor replaced and could only afford to go with an Ej20x. I am thinking to just get the same motor and put it in myself. Any thoughts/inputs? Example motor: https://www.ebay.com/itm/04-06-SUBARU-LEGACY-2-0L-4-CAM-DUAL-AVCS-TURBO-ENGINE-JDM-EJ20X/233549132863?hash=item36609cf43f:g:FuIAAOSwRIleiMfd I might consider doing a rebuild on this (the newer ej20x motor and not my current one) but not sure yet. I appreciate your insight and thoughts. Thank you.

Oh lol I knew that. I guess the only way to confirm is by taking it back to that shop but I have to figure out my towing situation.

Sent it to my friend who's heard plenty of rod knocks and he said definitely sounds like it.
