The first won't fit, ad is a bad idea. Think about it, the air coming in a t both ends will cause soooo many problems with the 2 and 3 ports. I like the 2nd type. It's more direct to the port runners and won't conflick each others flow. The one you have pictured on Chee's thread would be good except for the clearance to the bonnet. Best for a MAP system, but we could do it with an AFM. A little magic with the plumbing and..........
Hey! We have no firewall to the trunk!! Look at #2 and think about putting the TB's on the other side! How about eliminating the plenum altogether and mount the TB's on the lower part of the runners and eliminate the port dividers!
