Its a combination of factors to route the headers that way: mainly the orientation of the type 1 ports and my desire to construct a equal length system with as short pipes as possible.
The horizontal cooling made it then possible. It also neccesitated that the turbo was placed over the transmission and hence the need for the firewall to be replaced further backwards.
It took a LOT of work to accomplish those goals, but thats why its a hobby right?
