Hehe, yeah I know about the value of the cars. In fact, some consider the b16a a downgrade to the b18a so it's not going to up the value much if at all. The good thing is that the engine probably has less miles. But anyway, for the GS-R, if it was a real GS-R and they swapped out the b17 for a b16 then that would certainly lower the value. The question I have is if it'll be slower too.
