I don't know exactly what modifications are needed to make the 2820 fit into the stock box, but I don't think it is that hard......someone else has to know. I also think that they have that info. on the "other" site ( http://www.honda-tech.com/ ). I would love to take credit for my own design of the DIY Icebox, but after reading and looking around for a bit, this was the best, and simplest design that I found, so I pretty much simply followed the directions..........

Again, there are countless ways to do this, I just thought this was a good one. Conversely, there is a thread over there right now

discussing a design that is flawed for a few reasons......

If you want more links or info, let me know I think I still have a few sites saved.

I don't know what this did as far as power goes, but according to the butt dyno (and we all know how reliable that is) it is great - especially considering the price and difficulty. Basically, I am very happy with it - also considering this was my first attempt at modding.......I know, I know......I am a noob. I have been lurking around here for a while trying to pick a few things up here and there.
