I am in the process of gathering parts to add a 14b turbo to my D16a6 - 90 civic si hatch. I understand that I will need a hf header to mount my turbo to, but when I went to the pick and pulls, all of the model numbers were missing. When I say model numbers I mean hf, si, ect... I am not sure how to tell if the civic I was looking at was a hf. What sitcker says what model number the car is, and what am I suposto look for as HF hints. I know exactually what a hf header looks like, but the header sheild is always in the way.
