Default Finding good Short Block?

Well i found out my 07 STi has rod knock... i need a new short block.
I am wondering if I should buy a new stock shortblock, or rebuild mine...
At the moment what I want most is reliability, i can do with the stock power.
but then again i dont want to tell myself "man i should have just bought a built motor while i was at it.

Also what is the difference in ej255 and ej257?

Let me know what i should do, I'd like to stay at around 2-2.5k (which a new stock SB is 1.7k online)

Thanks (:

Preferably find a vendor near you so you can avoid huge shipping fees

Also if you have any metalic particles in your oil make sure to replace the oil cooler and oil pump. A killerb pickup while you have it apart is cheap insurance too against your pickup breaking and going through all this again down the road

I just bought a new stock short-block (EJ255), master gasket kit and new head bolts from Flatirons Tuning (SB was $1800) and the shipping was only $80 to my semi-rural corner of Kalifornia...

And their customer service is the BEST I've ever seen from a parts supplier! They called me in the middle of their epic flooding (Boulder, CO) to make sure I was ok with everything...

And if you're doing the work yourself, don't forget the AVCS system (solenoids, pulleys, cams, etc...)

nice shop, but i only see the ej257's and that was my question, whats the difference? They say "If you are putting this block in a car that it was not originally designed for, it carries no warranty expressed or implied." so i guess i would like the warranty.

Why not the sump? That's the easiest thing to clean when off the car and there are no "trap doors" or crevices for junk to hide in.

The EJ255 is specific to the WRX and the EJ257 is specific to the STi. The differences used to be more significant but Jon at Flatirons explained to me that the only difference in the new version factory short blocks are the pistons. The EJ257 blocks have a different piston installed.

And please don't skimp on the parts. I've found rod bearing "glitter" in every part of my motor including between the cam bearings and journals.

I know the oil cooler is expensive but there are dozens of threads where the owner opted not to replace the oil cooler and they were soon doing another rebuild.

I'm personally replacing my oil pump (new one is ACL/Orbit), pickup tube (new one is KillerB), oil baffle plate (new one is KillerB) and all three banjo bolts with mesh filters in the oil supply system since I can't ensure I'm getting everything out. My heads are disassembled and going out for professional cleaning with all the galley plugs removed and I'm disassembling my turbo and AVCS pulleys to inspect/clean them as well...

Good luck!

Thanks for the help and for the brands too, very helpful! (: Would this be managable by me and a friend who knows more about cars than I do? :P

Please keep in mind those brands are upgrade replacements, not OEM.

How comfortable are you and your friend at doing open heart surgery?

If neither one of you have ever rebuilt an engine, I'd STRONGLY recommend finding a third friend who has experience. Otherwise, it can be a very expensive way to learn.

I don't do this for a living but it's been a hobby of mine for a loooong time. My grandfather was a mechanic his whole life and got me started somewhere around age 7 or 8 (40+ years ago)...
