Sure the M53 doesn't go up to 1100hp, but the HPF kits are rather useless for high speed street/track driving, with limited to no control over their absurd power band. An ESS kit would be a better comparison. Using HPF as the benchmark shows how little you know, or maybe how far you're willing to go to fail at proving some new point that you are attempting to make. The comparison was between a relatively similar price range, which is a non-M (330) + FI vs an N/A M3.
Umm, the TT Stage 2 Turbo kit says it needs a new head gasket for the compression ratio(tearing into the head), needs 93 Octane gas(not 91!) and makes 375 rwhp NOT 450 rwhp. http://www.techniquetuning.com/bmw-e...st2-turbo.html
I don't even know what you're talking about with the M53
Oh and btw..Do you have/had a Supercharger or Turbo on your E46? How about a Limited Slip Differential on an non-M?? How about owning an E46 M3??? Well...guess who has had all of the above and has first hand knowledge on this. That's right ME! think maybe I know something now? *rhetorical question

Oh sure that it. maybe there was another reason for it and it's benefits. like:
Compactness is the primary reason. An inline six is longer than a V- 6, and BMW nurtures the inline layout because of its superior smoothness and sound. An aluminum block's cylinder liners take up space; with liners it would not have been possible to achieve the engine's 3.2-liter displacement without lengthening the block.
The second reason is strength. Given that this engine develops fully 333 hp from 3.2 liters - significantly over 100 hp per liter - its internal stresses are immense. According to M3 Project Director Siegfried Friedmann, BMW engineers researched a silicon-impregnated aluminum block (as used in BMW V-8 and V-12 engines), which would not require liners. But they became convinced that a cast-iron block could best sustain the engine's high cylinder pressures and very high piston speed at maximum rpm. (Current Formula 1 engines attain piston speeds around 25 meters per second; with 24 m/sec. at its rpm limit of 8000 rpm, the S54 is very close.)

We are talking about the M52/M54/M56 engines vs the S54.
That's a whole other topic and not in this discussion. You'll get no disagreement about how good that Honda engine is from me.
