Yes, upgrades are available. Alamo City Paintball (alamocitypb.com) sells delrin bolts. Viewloaderparts.com (or paintball-parts.com) has both upgrade and replacement parts. I would change the bolt and cocking knob. An upgraded barrel (the T-Storm is Spyder thraded) would be another good addition to your setp. If you are playing with a gravity hopper, I recommend a Tacamo (criticalpaintball.com) has them. My T-Storm also has a VL Pro Grip with a EMX 1000 board, but that took some hunting to hind an mount.
