i bought this awhile back and it's great and all but i was wondering if it's possible to switch the ballast to a 400w or at least something more then 150. and if i can how would i go about doing this?

Anything is possible. Let me tell you what you will need and see for yourself if you still want to do it.
1. need a new transformer with, cap, and igniter.
2. need a new socket you probably have a medium base, you need a mogul base.
3. The reflector portion may not accept the size of the 400w so be advised, also ballast/transformer portion may not accept the size of the 400W also. The mounting bracket is made for the 150W and will need new location to lock down the mounting bracket.
Good luck with your decision.
