welcome to the family!!!
white's a gorgeous color... was pretty close to getting that color myself (but i already had a white civic)...
anyway, have you checked out
www.evolutionm.net ? lot of good info there, if you can get past the "i'm better than you" attitudes, and infighting and Vishnu vs. Dynoflash bullshit that always pops up.
as far as mods, your first power upgrades should be turboback exhaust. intakes really aren't going to do much for the evo, as stock as it is. the stock unit is very good as-is. there have been some instances in which people have LOST HP with an intake. if you DO get an intake, you'll have to get flashed for it, and then you'll see moderate gains, so the cost adds up. i think you should just go turboback exhaust, boost gauges, turbo timer, boost controller, all the basic s**t first... and then get tuned as you put the intake on (and whatever else) so you save on cost and efficiency... some people have seen good gains with a K&N Air Filter. lot of people prefer the HKS RS Suction intake; there's an injen intake out for the evo now as well, and comes with upper IC piping--it goes well with the injen intercooler, which comes with the lower piping. but that's just my opinion of course.
anyway, awesome car bro, welcome to the fam... just don't launch it a million times and expect the warranty to cover that piece of s**t clutch
