Here is the manifold. I got it off ebay, but i don't think it is for sale on there any more. The description says it fits RB20 and 25, so I don't know how well it would fit a 26. I will say this though... For a CX Racing manifold, it is built very well. The material used is really thick, welds look good, and looks good inside too. Soon enough I will see how it performs.
