sorry if im saying somehting that has already been said but from my knowledge there are 3 factors in increasing the power output of any engine. these are factors of combustion to create a fire you need 3 key elements...Fuel, oxygen, spark so to create a bigger fire you increase any one of these but by increasing only one element creates an unbalanced flame to create a bigger and more efficient fire you must increase all 3 elements therefore to increase power in an engine you must increase fuel, oxygen and spark. fuel: bigger pump, bigger injectors, upgraded management to handle increase in fuel oxygen: less restriction but to a certain degree. intake tract lengths can be played around with to altertorque shift and power band (read: hemi intake) longer intake runners will create a more torqier engine, shorter intake runners will create more powerful engine. spark: upgraded ignition eg: msd twinspark ignition system allows more timing without pinging. great upgrade when changing the power band to encompass higher revs without sacrificing low end drivability. the next thing to consider is response. as previously mentioned alterations to heads, shaving, valves, valve springs, high comp lightened pistons to get really good power out of an N/A engine you need revs or displacement. revs: think F1. 2.8L v10? 14000rpm lightweight pistons, short stroke rods, high compression heaps of power high in the rev range anything less than 8000rpm and it runs like shit but when running more revs reliability decreases displacement: one area that might not have been touched upon would be stroking. rb32de?? i know it can be done with L series engines but not sure if it would be a viable mod to rb30de. would involve work on the internals and more specifically the crank. also dished pistons, playing around with bore and stroke. when playing around with stroking a standard production model rb30e might not be able to be used as the bores maybe too close together. nissan patrol rb30 block might be another option for longer stroke but not sure whether it would fit or whether it came with efi or whether it would be viable to turn into rb30de. the r31skylineforums have debated this topic for ages and i know that someone has gone through the motions of extracting 200kw or more NA keep in mind that the particular build in question was a no expenses spared operation. i think i may have rambled on for too long but hey my main point is that there are 3 key elements to extracting more power from any engine forced induction or NA other than that the previous information is quite correct again apologies for the long post
