casted closed deck or one that's been sleeved closed? I'm assuming sleeved closed because it's iron... but the other is all one material.
here's pics

I've yet to hear of any EJ loosing sleeves or cylinder walls. but i own a nissan so
given those sleeves are pressed in, and not physically part of the block its one more thing to go wrong, while it may be strong it could shift the sleeve leaving no compression chamber.
its a toss up i'd probably go with the stock block.

as far as I know, no one's blown the block up yet... but I dont want to be the first. The stock deck is open... the closed deck is out of another suby that's 2.2L and stroked to 2.4L. That's why I'm looking into blocks... mainly for the displacement. Some people sell the 2.5L sleeved and the 2.2L stroked. Those are the differences.

2.2 stroker is cheaper. The 2.5 needs extra machining done which costs a little extra. The 2.5 is actually sleeved down to 2.4 so there's more sealing surface area. The difference is probably $500-$700. Other than the extra machining on the 2.5, everything else costs close to the same.
So... same displacement, just 2 different ways of getting there. No one's really done a lot of punishment on either type yet. The options for motors I have is absolutely rediculous. No matter what, I don't think I can get enough hp to break either one of these blocks... I'm sure they both hold well over 500hp.

None of those motors are stock wrx motors. The 2.2 is out of an old turbo legacy. I have to buy internals for whatever one I pick. But, I'm not even sure if I'll pick one of these. I was just curious which one would probably be the stronger one since they are pretty much 2 very different ways of doing the same thing.

we were recently discussing this on the mr2 board. the general consensus was to just stick with the stock block. if something goes wrong with that, that is the time to invest in some sleeves. take the money that you would invest in some sleeves and put it towards some good engine management or thermal management. if you dont throw bullets at your engine it wont need to be bulletproof.

*sigh*
Just can't get you guys off the stock block can I?
Stock block is not an option. The whole reason in swapping blocks is for displacement increases. This is not "I'm worried I'm going to have too much power for my stock block."
