I feel like you should do it, and do an extensive install write up, I know you already have the first write up. You are bound to do things differently this time with previous experience on hand. I really really really want to do a VG30ET swap, or a VG33E-T swap. It is in my plans for the future, but being in college makes it rather difficult to have the time and money to accomplish such a goal, and L28et is much more attainable I feel.
