enjoy it for the quick car it is no matter what you do to it it's never gonna be a land rocket even if you get an srt6 unless you plan on doing some serious work and spending serious money, if you want more power then the n/a offers get an srt6 or jump in on the begi turbo project...as for NOS i myself and a couple other guys have it on the forum it's only gonna get you to about 13.5 or so at best in an n/a your gonna need to supercharge or turbocharge your car if you want 400 whp...
