You say that now. I'd think an m54 would be a great motor. Has s52 crank and more wall thickness IIRC. Plus aluminum block.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

I think its the fact that you have a similar displacement, thicker walls but overall less weight.sigpic

The block needs to be time-serted for studs and the oil pumps have a habit of shearing when the motor sees extended high rpm use. The M52 is the way to go - it has forged internals and will take a LOT of boost. Card counter was making over 600 whp before his stock bottom end blew up at around 680 whp iirc. The M52 is the best stock NA BMW I6 for boost.

But honestly where can you drive around with 630 hp?! Lol. That's so much! I'm not saying it won't be the funnest thing you have driven.. But other then a strip where can you hit full boost?sigpic

I will look into the m52, but i dont like the sound of it being a obd2 n having to put it back to 1:( although... if it has forged internals, then there would be no point of building it! Which that is a plus on the $$$$ side:)
Thanks you guys for the info.sigpic
