it sounds like your sold on the itr swap.. and since you want a comfortable 180 that is what you should go with, but just fyi a 96 to 00 b18c1 with just the newb thing to do...which is i,h,e puts down about one 160-162 to the wheels, but i'm gueesing with cams and valve springs and being tuned right it would be put down a greater amount of power.
