im going to have my buddy make me a top mount manifold for my project, i was wondering what were the advantages and disadvantages to havin a divided collector before it goes into the turbo, compared to having all 4 runners meet into eachother? if i have a divided collector id have to run 2 waste gates correct?

the shodan will probably be able to answer the first part of your question better than i will, but if you run a divided collector, to regulate the boost properly, id run 2 gates.
