question for those other apexi turbo cars out there:

I have the 'a' version on my track car and I am interested in the 'b' version manifold setup since it positions the turbo in a bit better location, I just dont know all that is needed for moving to the B version setup, obvisouly i dont need the actual turbo if the A version fits the B version manifold and DP, so anyone have some info for me?
