Hey everyone well i'm about to purchase a skunk 2 pro series Intake manifold for my ITR which has skunk 2 stage 2 pro series cams, the thing is I also want to buy a skunk 2 throttle body and I'm thinking of either getting the 70MM or 68MM but of course the 70mm is bigger but i heard it can make your car loose power if the opening is not the same on the IM????which one should i go with????thanks

 

a tapered 68->66mm tb would be decent. make sure to port match the tb to the manifold opening.

 

does anyone know what the size opening is on a skunk 2 intake manifold??

 

ttt

 

64mm...?

 

65mm i believe
