^^ you wont need an Intake
or header. about the only thing you can get would be ..(to benefit N/A and still be used on turbo)
1) new oil pump
3) better valves/springs
5) PFC (00-02 models) even with this your tuning will need to be redone one you get turbo.
Other then that everything else will over lap.
it's best to pick a route and go directly, trying to do both at once will waste money. better to stay stock while your gatherong all your parts and then one day have a bad ass motor. you will save a lot of $$ and trouble.
actaully i have heard a lot of problem from people running more than 7psi on stock intrnals
hmmm must be poor kits or bad tuning. done properly it will hold IMO. I also can't recall anyone having promblems with boosting over 7 on stock internals. got any links?
