dont think you need a k04...i have kept even with my friends HR 350z with dual intake and exhausts and im just stage II with a HPFP. with a upgraded intercooler and meth it should be a steady pull
Sweet runs man....K04 FTW!!!!....ppl constantly overlook this turbo and how cheaply you can build your own kit....I have a tweaked tune on mine w/ meth and let me tell you its pretty damn quick for such a tiny turbo
