i'd also look into getting and over bore tb.

i have a skunk2 manifold for my b18c1 sitting at home, and it's mated to the ericks racing 70 mm tapered to 68 mm tb. i'm having the skunk2 manifold port matched. 70mm is a tad big for a NA motor, but eventually my motor will see boost.

you could look into the 68 tapered to 66 tb from ericks. but it looks like your down with doing engine build up. so i'd recommend the 70mm tapered to 68, and look at doing vafc or a chipped p28 or something, or even a hondata but i find that hondata is beneficial to the boost motors than the NA motors.

if you plan to rev your motor past the stock redline upwards of 9000+ rpms, than the JG may make more sense, but honestly the skunk2 would make more sense for the street since you won't be redlining it at the merge lan.
