all that will cost you half of what suggested above and will produce 85% of the gains.
The text that I put in bold isn't entirely true, if you had enough money you can throw an S85 engine in there which would make it more powerful than a 335 in every way and there was somebody from 1-Series forum who completely rebuilt his N52 engine that produced around 340+ HP naturally. No SC or Turbo but it cost him a fortune.
