well, its got a dc sports header, jdm password carbon fiber intake, skunk two intake manifold. The man i bought it from (yes its bought not built, that only downfall) said it had type r pistons, and something about hotter cams. the only reason i'm wanting to upgrade the brakes is out was out driving rather aggressively the other day, and both front rotors were glowing orange, and the brakes got a lil spongy. when i stopped the drivers side caliper had actually caught fire.
