Sorry for the thread jack :P

well i thinks its the fact that manufactures are building more reliable more fuel efficient cars hence the high compression and advanced computer systems. now granted the n54 motor is great with forged internals (from what i have heard from bmw techs) but the built it with really high compression for a turbo motor... beats me why but my guess is economy. but that prevents increasing boost safely. thats why 2jz motors can hold up to 750whp, cause the whole motor is forged and the compresion ratio is somewhere around 8:1 stock. just my .02 cents any body else with more info can chime in but as for the op's original question someones just gunna have to push that envelope!! haha im def curious
