FaderUS Posted January 13, 2017 Share Posted January 13, 2017 Hi all, Any issues with swapping a short block from a 2010 turbo into my 2005 legacy gt 5eat? I would be using a VF52 turbo, heads, and all accessories from the 2005. Link to comment Share on other sites More sharing options...
fahr_side Posted January 13, 2017 Share Posted January 13, 2017 (edited) The oil pan on the 2010 has an extra bolt but the '05 will bolt up anyway. Need to look at the turbo oil return as well.

FaderUS Posted January 13, 2017 Author Share Posted January 13, 2017 Thanks. To clarify I assume I would use the 2005 oil pan? I will dig around for some pics to see what extra bolt you are talking about, but haven't had my coffee yet. Do you see the turbo oil return as a problem, or just something that needs a custom line made? Link to comment Share on other sites More sharing options...
FaderUS Posted January 13, 2017 Author Share Posted January 13, 2017 And to clarify this is a short block. No idea why I typed long block in the title. Is there a way to fix the title? Link to comment Share on other sites More sharing options...
Rhitter Posted January 13, 2017 Share Posted January 13, 2017 It's just low mount turbo v high mount turbo. Need to look into how the oil return is done and if that makes a difference to the short block. My OBXT build Link to comment Share on other sites More sharing options...

GTEASER Posted January 13, 2017 Share Posted January 13, 2017 2010-2012 uses a different motor mount system. There is a mount on the front (effectively the pitch stop) and no mounts on the engine itself, they are on the tranny bellhousing in the 5th Gen, so make sure the block has threaded holes for the traditional engine mount locations.

xtea Posted January 13, 2017 Share Posted January 13, 2017 Swapping in a 2010 and doing a low mount build would be amazing! Link to comment Share on other sites More sharing options...

The original motor mount pads are still there on the later block and the 10~ front one just bolts on. I've seen a '10 block in an '06 WRX.

mwiener2 Posted February 4, 2021 Share Posted February 4, 2021 2010-2012 LGT motors mount to the body by the oil pan. There are extra bolt holes (2) along the front edge of the pan mounting surface. These are 8mm holes whereas the rest of the EJ's are all 6mm holes. 4 of the 6mm holes have been enlarged to 8mm for a total of six 8mm mounting points that the rest of the EJ's don't have. The actual block casting is slightly different. It has been reinforced to accept these larger mounting holes. While it may be possible to retap and add these 8mm points to an EJ257, the lack of reinforcement may cause the oil pan to separate and leak, or the case could crack under the stress. Other than these changes to the oil pan mounting, the blocks are the same.
