My IS300 has a T66 with all supporting mods and 264 cams. I am upgrading to a SP77 and am going to ditch the cast manifold for sure, and from the little research i have done the next major restrictions are the head/intake. My questions are:

Which one is the bigger restriction? I assume it would be the intake and TB?

How does a ported NA head flow compared to a TT head?

What aftermarket intakes and TBs are available?

Any info would help. Thanks.
