Best Forged Pistons for EJ257
Hi !
As you may know, I have head gasket failure
I'm in shock because I've never take part in any track day runs !
I have used search engine but i haven't found any useful (for me) information about forged pistons.
Subject: Stock Subaru Impreza STi MY06 with EJ257
I'm very keen on buying and rebuilding my engine on Cosworth forged rods and pistons, but my goal is to minimize piston slap. Is it possible ?
Cosworth is the only brand i know and wich I trust. i dont like go with Mahle or CP piston or other brands.
I've read that the pistons are gaining volume when there get to right temperature, and the oil consumption will much increase, due to lose piston fitment to cylinder.
I'm using my Car as a daily car but i'd like to have circa 320-340 hp
Please help guys !

Cosworth supply a plus .25 piston which would suit you. I wouldn't recommend just "dropping in" a forged piston in the hope it'll fit.
We can offer you various solutions, some of them with a discount!

Thanks chaps for quick reply. It wlil be first time that im doing this operation, not by my self but well respected tuner. But im concerned about the piston, it will be smaller about 0.007 than the bore and is it a bit loose ? Could it be more thigher ? Like 0.005 ? Will it be safe for the bore to avoid scraching it ? How much forge pistons expand in optimal working temperature ?
Im a bit frightened this whole operation.
