Expert please ??
Yeah, I know I keep changing my mind :o

I found an EJ257 short block for a great deal, and it's an '08. It has a different part # than the up to '07 block. Doe anybody know if there are any significant changes that would prevent it from working with my 2.0 heads and pan. Thank you in advance

It will work fine for you.

What are the differences? I'd be scared to walk into a build with just this reassurance^. lol, no offense Kjott.

An EJ257 is an EJ257 no matter what the part number is. There are some differences in the parts used or something like that but the block has the same dimensions and everything.

Best way to get your answer is to call someone who builds Subaru motors and ask them. Ron from Raw Performance or Dom at Maxwell Propulsion will be able to tell you for sure what the differences are.

I just looked at the Shop Manuals for each and they both appear to have the same mounting points and use the same parts except the shortblock has a different part number

Further research shows that while this block would have worked for me for certain, the '08s are having major breakage issues. Both PDX and Cobb recommended replacing pistons before doing a hybrid (2.0 heads) set-up with an '08.

I opted to take the path of least resistance and just bought a used EJ205 (complete) with a one year warranty. I should be driving the wagon again in about a week !Thumbs Up

sounds good...I thought the breakage was limited to the 255's though??...I still find it strange that these things are breaking so much when there like the same thing as 07's...and both of our wagons are going to be together in about a week YAY!!!!

Chase 05-22-2009 10:32 PM

Ok, I actually wasn't sure if they used the same block. If you already ordered a 205 then it doesn't matter, but you probably know the 257 has had continuous problems with broken pistons since 04. Unless you were trying to save money and were hoping they had upgraded the pistons since all the problems... I'm surprised they haven't.

I really dont get how subaru has had such lax quality control on these freakin pistions...I mean last weekend I saw an STi with stock internals throw down 540whp...but I've also seen them grenade at 400whp its rediculous

Chase 05-22-2009 10:52 PM

I've heard of them going as early as 11,000 miles on near bone stock setups.

On NASIOC you hear stories of people with 08-09's that are going with less than 5K

baller_v24 05-23-2009 12:54 PM

True, when i was getting my car tuned, I was talking with my tuner (Keith, and he said that subaru have started going with a different manufacturer that uses a different metal for the pistons. As subaru is cutting costs. It has the same part # though.

If I remember right i think they either started with the 07's or 08's. Dont remember.

basco 05-23-2009 01:26 PM

yeah i remember my mechanic telling me the same thing last year when i was thinking of going hybrid (victor @ BigValleyPerformance)
