all in all, being a first timer, I'd try to get one already swapped and learn from it. It's basically all done so you can take it appart and back together and learn as you go. It would be harder to build from the ground up being a first timer to this. I also agree with the other guy, RBs are heavy and unless you're going for the RB26dett, won't really get you a whole lot more than a built SR20det would.
