			Lots of different ideas on this.  I looked into engine mods a few years ago as I used to hot rod a lot of Fords, Chevys, Hondas, and Nissans.  With very few exceptions I found engine mods on a 2.5L to be just a big black hole for Benjamins.  Very little performance return/dollar spent.   
 FWIW every Boxster class track record on the West Coast was done in a car with a stock motor.  No turbos, no chips, no plenums, no nothin.  They did their mods on suspension, weight loss and tires.  This is where I am doing my R&D.
 
 Ultimately it is your car and your dough.  Do whatever you think will make your car what you want it to be.
