Couldn't resist.

just start a new thread sheep. this one doesn't belong to you anymore.

LOL so true...

Guilty.. In all fairness, the answers to his questions were... Has anyone obtained 570hp from their E63, and the question about differences in the SLS and W211 E63 engines was answered. Unless I've missed a thread, nobody has added enough mods to their W211 E63 to make that much HP except the people on youtube that added a weistec..? Anyone getting 570hp?

No, but if I ever blow up my motor, i'm at 73k now. I will go ahead and put together either a custom job, or I will go through OEM for SLS parts.

I want forged pistons, connecting rods, a nicely balanced crank, etc.

But I really think this motor will go another 70k problem free.

any other internal differences (cams/injectors?). If nothing big, i'd figure efficiency upgrades (headers/exhaust, throttle body/filters) would naturally open things up, once the tune is matched to the new components, as well as perhaps pulling a little more power from the tune itself (think about how much power is robbed from the C63 engines just by its tune).

Any 63 guys done the full Kleeman setup as listed above (tune, headers/exhaust, TB/filters? even if not through kleeman)
