So you'd have to bore your engine?
What about the piston compression height, deck height and chamber clearance/squish?

Wat is wrong with the pistons? Are they really the weakest component in the rotating assembly? Just asking.
yeah - first I heard of this, plus, aren't some newer pistons having cracked land problems? Dunno that WRX would be an upgrade.

I would spend the money on the right size forged pistons before boring it out. You are talking a big jump in bore size which will probably require a re-sleeve. That money and effort is better spent on real pistons.
Get the tune right and keep dumping water/meth in there and the stock pistons should last a while.

pistons same dimensions as the wrx one just slightly smaller the wrx ones. Is there even any forged pistons avalible for a 3.0 six ?
That's the first result I pulled up. Wouldn't hurt to call wiseco or any of the other big piston manufacturers and ask what they have.
A 2.8mm bore is big. The stock steel sleeves would probably be weakened enough by that to split under boost. So you're looking at re-sleeving the engine with these:
You'd want to use forged WRX pistons too, so add that cost on top of the sleeves and the machine work.
That still leaves you with the stock rods. I found a few references to forged ones made by Pauter, but that's another $1400.

The WRX pistons are 2.8mm bigger diameter than the 3.0l ones.
... the wrx ones are bigger so it might not work ...
...unless you send the Block to a Machine shop to change the Cylinders (Walls) on the 6 with the WRX ones, but that should be very expensive, isn't it?
