Have you had a piston out of your motor to check?

I'd take nasioc's info with a pinch of salt.

MRT say that My00 - MY06 all have forgies.

Nope, and so I'll likely never know. but it's not just nasioc that say the v8 STi did not have forged pistons.. It's all over the internet...

If yours has cast pistons you have an EJ205.
Pretty sure my old 204 didn't have forgies, I have the pistons here and there is no HF-3 or HF-4 markings on them.

I'll post a pic a bit later.

I thought so Russ as I looked into it before but Ross is saying "all 207's" are forged.

Yeah it's one of the very few times he is wrong. Let's laugh at him while we can! Might not happen again... Haha
