The N54 engine pistons are cast (and not forged).

I had a shop open the motor up to determine any upgrade routes or to see how much HP it should support. They took the piston and compared it to some other cast BMW pistons. The pistons were forged and comporable to something like Wiseco.

No question was dedicated or referred to the old built date N54... So... Remember, 3 guys with earlier built date engines opened their engine in a reputable shops and got confirmed by their shops that pistons are forged. I think that's enough as I agree with you, it make NO sense to use a cast pistons and forged crank.

Oh nice you opted to get the rubber pistons. I knew I f__ed up when I requested my pistons to be made of styrofoam.

I heard from my SA that the forged internals came with the sport package...
(<-- That means I'm kidding FYI)

I think it would take a pretty experienced eye to spot the difference btw a forged and a cast piston without one or the other to directly compare it to. That said, lostmarine and numerous others have been running around on 500+ whp for a while and Shiv and Terry have literally beat the fuck out of their motors with no issues. Unfor hitting 660 is further evidence that this discussion is rampant speculation and fail. Until someone blows with "cast" pistons being the cause, you can all rest assured that your motors are bombproof. |

Thanks boom.
Guys, BOOM is/was ? a cp-e expert. So they never disassembled the block , good to know. But it does appear more and more the 2006 builds get the good shit, so to speak . Personally, my car was making 660rwhp and the motor was taking it just fine. |

I am by no means disputing what manufacturing process went into making our pistons. HOWEVER, Honda uses a boat load of forged cranks and cast rods and pistons.
