Need a little info on an LSD Selection for a D16Z6. I looked up some information on Honda-Tech and looked through some threads here at hondaswap and found 2 choices. I hear on (on select few)D15 Trannys has an LSD, but only for automatic. and I also hear that Quiafe makes one for the D16Z6. Are those my only choices? And is it true that the D15 tranny only has an LSD for automatic, and is there any way for me to get it to work with a manual?
