If you still want to do a V6, I found it to be a faster and easier to remove the body off of the 4 cylinder and put it on a v6 frame, You get beefier frame rear springs and better front brakes, you can gen 2 alot more stuff and the swap is pretty simple. Don't forget to change the fuel pump before putting on the body. (no access panel in the 2.6 over the V6 fuel pump plate) and a good time to do a body lift. I found a V6 real cheap because the body was so rusty and then took the left over parts to the scrap yards and got most of my money back.
