Thanks everyone for your input. How would I know if my current turbo is a HF? Can you tell by looking at it???

I would have to go out and drive it to be sure but Iím thinking that it starts noticeable spool somewhere around 2500rpm. Also... there has been reference made to the "cool" side of the IC. Which side is that??? (Sorry my knowledge base is very limited. but I'm working on it...) The weather isn't too bad today so maybe I'll drive it to work and get a accurate spool point.
