Well, unfortunetely, the system that I am going to build is almost EXACTLY like what Nubius has. He took a RAD from a 1977 Bonneville and modded it, and I got one from an 86 Chavette and I am going to mod that. Other than that, I am getting the same pump and the same size hosing. I may be getting a different waterblock, but I'm not sure. I am going to sell my Aquarius to my friend, it does suck. I get 107F with that, thats rather high for H20, put since it is low end, I guess that is what should be expected. The waterblock is also Copper/Aluminum, so I imagine it is starting to corrode. The pump is also small, and the tubing is ery small. I think 1/4".
