I want to ask where to mount external wastegate? Will it be ok to mount on 2 cylinders on 2wd manifold (on one side of the header)? As you know 2wd manifold is of 2 parts and them are divided. One side flows from 1 and 4 cylinder, another side is 2 and 3 cylinder. will it be ok to waste only form one side? in other words from 2 cylinders only?

What are the disadvantages of such setup?

Thanks
