it is neccessary to port out the intake manifold to use a 58 mm TB? I haven't taken it apart yet, but i dont want to, not get the manifold ported, and then find out that I need to do so to run the 58 mm TB which seems like it's going to be too big. Also what elbow to use to make that work? stock seems too small also, just looking at..

stock elbow should work
and the openings will need "bored out too 58mm too work right
a 52mm will work without any boring at all
