MazdaSpeed 6 & Mazda 6 Engines

[Garry68]

Does anyone know if the internal engine components such as the camshafts, pistons, connecting rods and crankshaft are identical in the MS6 and the M6 4cyl?

 

[EricsMS6]

They're different.

 

[bova80]

yeah completely different

 

[6speed6]

MS6 has forged internals from the get go.

 

[bova80]

so mazda says, but i think someone has tested them and they aren't forged.

Thanks gentlemen, I'm convinced
