The EJ25 is essentially a bored-out EJ22, so logically this must mean the EJ25 pistons have a larger bore, so no, I don't think they'll fit...

You'd be better off getting custom pistons ground. What kind of "big power" are you looking for?
Also, do you have an extensive mod-list and dyno-chart? I'm curious as to how you got 180whp and what the power curves look. Also curious about the 17" "icw" rims.

There are a couple of ways to approach this.
1. Overbore using the stock sleeve. Many will tell you the sleeve gets too thin to use at this point, but others have done it.
2. Overbore and resleeve for the 2.5 pistons
3. Get custom forged pistons for the 2.2 from someone like AxisPowerRacing.
As for stroking, which is a totally different beast, you use a 2.5 crank, but had better be sure your pistons are matched to the new stroke.
You really haven't given us a lot to work with here. If you want more detailed and specific answers, give us more info. Like budget, desired HP, what turbo and boost you plan on running, etc. But the basic answer to your question is NO, EJ25 pistons do NOT fit...
