Yea I understand the wiring, I actually did swaps for a living for several years. I am 100% comfortable with going in either direction as far as the work goes. I didn't know the charger was the same as the d series I did know it was smaller than the vtec one. Still though on a auto CRV it should still do what I want.. I could do GSR-JRSC since I have the engine already. I was thinking of selling the GSR to cover some of the cost of the charger but?
