hahaha your s14 looks like a shopping cart
and why would you put babies on a rb25? JK :P
I would just stick to a GT30, much less effort thant running twins, and would be equal or better, the rb has so much output that it will be very responceive, becouse of the starting tourque, then the turbo so it should be fine. I also designed mine for quick responce by building a custom intake manifold
and by the looks of your set up currently I see that your going v- mount? this will also add to responce by having shorter piping, we org were going to do a vmount but there is no room in a stock bay, soon i will have a v mount something in the z, becouse of the space if i use a 4 cyc like a sr or something.
