Also has anyone chased any power with the M54 on here? I've never build an engine up for an SUV and I know the drivetrain and 5,000 lbs is going to change the game but curious to if anyone has done so. The torque being as important as it is most common mods you see on a 3-series, you intake/exhaust bolt on stuff kind of becomes irrelevant.

If anything I would want to stroke the m54 to make it a 3.3-5L but a $4,000 crank shaft is a little excessive on these old beasts.
