I am doing a LIM this weekend, so I might as well grind a little on the blower while I am in there, but I am new at this so any more info is appreciated. What do you mean by 'tape up your needle bearings'? Where can you get a coupler, and what does that usually cost? Can you port on an otherwise stock car, or is this only for modified cars? Same with the open cone-is that only for modified cars or is it fine if this is the only mod so far? Will I need to replace anything else if I port (like the bearings, shafts, etc.)?
