The small fitting in front is for the boost gauge. The one in the rear is the 993 compressor bypass valve. I bought the core from a guy that builds custom cores. The reason I went front to back with the charge air is because I wanted to eliminate boost loss. Side to side has a chance for more boost loss. I bought the tubing from Burns Stainless. The size of the core is 22"x3"x8". I could have gone a hair wider but I didn't. The other reason some go side to side is the plumbing is different with the stock 3.2 manifold and side to side makes sense in that application. I would buy a Spearco core next time. I had to wait too long for my core to be built.
