Mazdaspeed6 engine?

[mspeed101]

I was trying to do a search on it but could not find the info I was looking for. Will the mazdaspeed6 be using the same 2.3L engine as the regular 6 or will it come with stronger internals or what? Also what size turbo will it be equipped with? thanks

the internals are forged

Different fuel system (Direct Fuel Injection).
Different Compression
Different internals

Its a nice built up engine, but its had issues in production with both the turbo's and the DFI, so reliability will be a ? until the second batch is avail.

No way the internals are forged, maybe upgraded, but I doubt their forged

They are forged. I read it.

I do know for a fact they went from a cast iron crank to a forged steel crank. Since the rods in the standard 6i are sinter forged steel, I'd assume they are also forged in the DFI MPS 6 engine as well. The pistons are at least hyperleutic with moly coating on the crown and graphite coating on the skirt. Don't know 100% if they are forged or not.
