    Use a good quality oil and get a good quality tune. That should be it.

    From my understanding, correct me if I'm wrong... The ring land issue is mainly on the the STI's. And it happens on completely stock and can happen on any tune.

    IMO if there is no tune, there is a better chance of warranty coverage if it does happen. A tune can have the dealer deny the warranty claim no? One of the reasons why I'm keeping mine stock except for the tints and overlays.

    Do your regular maintenance and keep receipts!

    I wouldn't worry about warranty, if it does happen I'd want to replace the pistons with quality ones because it would prob eventually happen again. I'd rather just drop in some quality pistons and not worry about it.

    Well Im not worried about the warranty moreso to say, but I do want a reliable car, seeing as the car I came from was damn near bulletproof.

    Stock is boring. You can't back up the stock tune & replace it if you need to see the dealer?

    Wht mostly on stis if they have the same motor?

    It was on an earlier thread... It was discussed... Not sure why more on the sti and less on the wrx. I'm on the iPhone so it makes it somewhat difficult to search on my end and post. When I get on my notebook, if I remember I'll post the link up if I'm able to find it.

    I still really can't find out why wrx's aren't mentioned. They have the same motor. Different tune b/c of the different turbo I would assume.

    The EJ257 and EJ255 are NOT the same motor. There are a number of differences: pistons, piston dish, crankshaft, main bearings, oil journals, head volume, quench area, compression, etc.

    Who told you they were the same motor?

    ^This. They aren't the same.. most notably concerning ringland failures is that the pistons are different.



    How to prevent ringland failure? Install quality forged pistons (CP, Weisco, JE, Arias, etc.). You're not going to crack a ringland on a forged piston unless there is something seriously wrong with your tune (or something else fails, like your fuel system).

    I assumed they were the same b/c they are both 2.5. I just thought the turbo was different. So I'm guessing the EJ255 is the wrx motor? I need to research the specs of both motors, now I kno they are different.

    Well yea but I'm saying without dropping in a built motor.

    255 is the N/A engine, 257 is turbo'd
