akaziggy Posted June 16, 2015 Share Posted June 16, 2015 Mine is an '09 LGT. 2000 miles ago, the entire upper was replaced (heads, gaskets, cams) new. About 1000ft ago the lower went on me. Now I'm told I need a new short block. Here's the question: What kinds of short blocks will match up? Do I have to find the factory correct one (or only one from an '08/'09 LGT), or can I use anything from a turbo engine from '02-'09? Anybody seen/done this one before? Or anybody have a lead on one I can get my hands on? Link to comment Share on other sites More sharing options...
V8lolsubie Posted June 16, 2015 Share Posted June 16, 2015 Need to search buddy. Shortblock replacement is so incredibly common on here. Otherwise your stock block is coded as an EJ255. You need to source one from an 08 and newer STi for the best overall bang for your buck. Those are coded as EJ257. ANY EJ255 or 257 shortblock will work. Those coming from 06-09 WRXs or even newer up to 2014 as well as 04-15 STIs. Easy math with bring you to this. Search ebay and buy one new from a dealer or distributor. They are like $1800 brand spankin new from Subaru. If its a 2.5l turbo engine that needs replacement, Subaru will use an EJ257 shortblock. Link to comment Share on other sites More sharing options...
ras06LGT Posted June 16, 2015 Share Posted June 16, 2015 Heuberger Subaru (a vendor on here) has the best prices for a new EJ257 shortblock. Buy one from them with a gasket kit. Link to comment Share on other sites More sharing options...
akaziggy Posted June 17, 2015 Author Share Posted June 17, 2015 Okay, V8. What if I found a block from an '05 LGT - coded EJ255. Can I plug it in? Link to comment Share on other sites More sharing options...
rmoore5 Posted June 17, 2015 Share Posted June 17, 2015 Okay, V8. What if I found a block from an '05 LGT - coded EJ255. Can I plug it in? The 2009's have an air pump. The heads are different. There are mods to allow this swap. The short blocks will interchange, there might be a slight c/r difference I think I read here. It is highly recommended against using a worn turbo engine. You know by now the reliability of the a worn subaru block in a performance application. Do some reading on this site and you will learn a lot about these motors.

You know by now the reliability of the a worn subaru block in a performance application... Yeah is this a used block rebuild by someone or junk yard unknown miles as is at a steal of a price compared to a brand new one? If you find a rebuilt block, see if you can find some papers with it saying specs or something. You don't want to pull the engine twice for the same reason in such short a period of time. For less headache I got a new block and called it a night. You still have to deal with water pump, pulleys, oil pump, timing belt, oil cooler, head studs and a few other things to kinda put all that effort, trust and money into an unknown dirt cheap Trojan horse backpage shortblock. <Had a simple fix, took cheap way out and haven't really driven the car in years. Shortcuts cost you a shortblock, a turbo, some cams or maybe even the longblock. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...

akaziggy Posted June 29, 2015 Author Share Posted June 29, 2015 Hey guys. I found a reman'd ej257. Do you know if that will match up with my upper (because that's all new)? And is there anything else I need to put it together? Max-you talked about a gasket set?? Link to comment Share on other sites More sharing options...
Max Capacity Posted June 29, 2015 Share Posted June 29, 2015 The ej257 will fit, you need the gasket set for your year car. That's so the head gaskets match your year heads.

akaziggy Posted August 17, 2015 Author Share Posted August 17, 2015 Update: The 257 is in. Now I have new reasons to worry. The new motor is a little 'knocky' sounding - I can hear it working. And yesterday we had a scary moment: I was on the freeway and downshifted (to make up some time...), and when the engine started working hard 2 things happened. The motor "missed" badly (which is a real scary feeling) and immediately threw a code - P0244. I found out that the shop DID NOT reflash the ecu after the new motor was in. I've talked to two people that think a reflash will solve it. What does the forum think? Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted August 17, 2015 Moderators Share Posted August 17, 2015 Isn't P0244 an overboost code? If so, that's a terrible feeling when it happens, but not really bad for the car. If you have mods that are unaccounted for by the current ECU map then loading a proper tune should certainly help.

akaziggy Posted August 17, 2015 Author Share Posted August 17, 2015 There are no mods at all - I only replaced the motor (as if that's a small thing). Help me out with verbiage: tune=reflash, yes?? Link to comment Share on other sites More sharing options...
ras06LGT Posted August 17, 2015 Share Posted August 17, 2015 A re-flash is just re-loading the existing ROM. A tune is modifying it. Re-setting the ECU allows it to relearn the stored values for fueling and whatnot, but doesn't change the engine performance. Re-setting the ECU with the new short block is a good idea. Check to make sure all the vacuum lines are connected correctly, specifically anything going to the BCS. You shouldn't really be overboosting on a stock vehicle with stock tune. If you are still on the stock tune you should fix that. A solid stage 0/1 will be better for the car. Link to comment Share on other sites More sharing options...

And another thing since my car has been sitting for at least 4 months or so and about a 1/2 tank of gas should I do a full tank before I start it? I find it extremely odd I was able to get it to start it once to move it off the flat bed but I can't get the car to start at all anymore not that I really care at the moment.

You use stabil in the tank when you left it? It's not nearly as bad as my tank of gas from when I started this rebuild in 2011. 2005 Satin White Pearl Subaru Legacy 2.5 GT Unlimited 5EAT (Project Car) 2019 Agate Black Ford Explorer XLT 4WD (DD) Link to comment Share on other sites More sharing options...

Nah I forgot to put it in I mean if I'm really anal I guess I can figure out how to drain the tank.. I don't think it's going to be as easy as getting to as my outback wagon was... I'm guessing 1/2 is about what 8 gal or so? Link to comment Share on other sites More sharing options...

Cable and software is all you need to datalog and send to a tuner from here to tweak and send back to you.
