I was looking to get intake manifold cut open ported and polished I have a skunk2 pro series and a aebs manifold to choose from. I am using a gsr head and I heard that the aebs manifold was designed better for the gsr head something about the angle of the runners on them also the plenum on the aebs looks a little larger than the skunk2 one. The manifold will be going on a 2L build that I am putting together (pro2`s,84x89, 12:1). Also what size throttlebody do you all recommend to use? I currently have a 65mm throttlebody and wondered if I may need to go larger. Thanks in advance.

 

Sell the Skunk 2 so you got money to port the AEBS.
