I don't agree 100% with F/I over N/A. N/A does have benefits. Biggest one is classing in certain types of amateur and pro racing. F/I places you into a whole new ball game. Also F/I in the long terms cost more. Maintenance and up-keep is costly on a F/I car.+1 if you have all this money to go and build an NA car then just do FI its cheaper and you'll wee more gains for the price of all these NA mods to even hit 300whp you can buy a Vortech SC kit and be throwing down 340whp for cheaper do reaserch.... bottom line
My post you quoted wasn't ment as F/I is "better" than N/A. More of that the owner needs to first figure out what the purpose of the car will be and what their budget is.
IE: I'm seriously considering a Z34 and plan on making it 90% road racing and 10% weekend cruiser. My first mods I feel will benefit me on the track are; oil cooler, better brake pads and, a wheel/tire combo. After that a Quaife diff. As I haven't done much research on mods for the Z34 I don't know what to do after that. But as you can see, N/A is my preferred choice over F/I. I guess owning a TT350Z has taught me a lot of the benefits & downsides of each.
