It doesnt matter if its a GSR (its not an ITR motor). Its based on the mileage and the condition of the car. If anything, you can replace the ITR parts with stock integra parts and sell them separately instead of selling them w the car. You probably make a little bit more that way. But that is up to you. Exterior is not so great. It all depends on the buyer. But go with KBB value first, then look around and see what they sell around your area or somewhere close by. You can price it accordingly then. Hope that helps you out.
