yeah the 1st gen can handle it with a lot of internal work. you'll need to lower the compression and beef up the internals quite a bit so that the motor can handle high boost AND nitrous.
you can get any intake system you want, just the CAI's benefits arent as great on a turbocharged car so i wouldnt go blowing your money on an AEM when you can just get a short ram and add a CAI.
also, be sure to choose a quality BOV.
www.turboxs.com has incredible BOV's. most think "oh hey thats loud, i like the whistle" etc etc. a BOV should sound like a loud sigh of sorts, not chipmunks giggling (due to the fact they are not made as well and serve more of a "sound" purpose than a "performance" purpose).
also you'll probably want to run a nice 3" cat back system (not sure if you want a cat on there or not, but if so 3" that badboy as well).
electronics come in many forms, blitz makes a GREAT boost controller, its so easy to use, on the expensive side since its EBC (electronic) and not MBC (manual). but damn its wonderful, and you can set it with 2 diff settings (one for street, one for race).
GReddy gauges are also pretty good investments, Blitz and APEXi as well....and of course autometer which will probably run you the least amount of money. unless of course you like real lit up gauges then there are the units from VELOX which light up diff colors and such.
you will really have to spend some time on the dyno to get everything working properly and in unison to get the most power.....remember its important that all yours mods work well together, not that they do amazing crap all on their own.
if you have any other questions feel free to hit me up on AIM (hybrid3do0rcx) anytime and ill be glad to try and help you out.
