Even then some people were still adamant that the STi's had forged pistons...lol...

I actually will not believe that the pistons are forged untill someone tears a block down and posts picks. It wont be long untill someone puts a MBC in a new 08, boosts to 25psi, gets afr's at 15:1

Agreed. Within the next 90 days some unfortunate scout will play around with an open source reflash, and grenade his motor in the process - it'll get opened up and then we'll know.

We also heard that the 07 had forged pistons.

Obviously, this wasn't true.

dareseven · 12-28-2007, 03:49 PM

Man I hope they are forged. But, I have high doubts.

JJ18Sniper · 12-28-2007, 11:09 PM

Any news?

pantag · 12-29-2007, 10:13 AM

I highly doubt if they are forged. It would be in the official release statement from SOA.

***Szumita*** · 12-29-2007, 10:17 AM

how nice would this be... they should for the bigger price tag...

JJ18Sniper · 12-29-2007, 10:29 AM

It would be the ideal OEM replacement block for us too...

Im no tuner, but wouldn't it need the 08 ecu as well due to the extra cam adjustment taken on by the ecu?

Updates on this?

This was posted over on NASIOC this morning:

"FYI: The 08 has the same pistons as the 04,05,06, and 07. The crankcase is a new issue number, but backwards compatible, so likely not a significant change. The rings however are a new part number, not listed as backwards compatible. They look the same, but perhaps have some difference in material. Everything else in the block seems to be the same. The 08 WRX has the same shortblock, so all internals are the same as well. Obviously the heads are different, but they have the same size combustion chamber (56ccs), and similar size ports.

I knew we wouldn't get that lucky.

Flycaster · 12-30-2007, 07:17 PM

BTW, I just thought I'd add that all of this is "eyes-on" confirmed - Sponaugle tore his brand new motor apart just to have a look-see.

He referred to block replacement. With only a short block mod, you can use your old ECU.

Well thats that...another letdown about forged stuff...par for course.
