it IS going to cost a lot to build up that engine, but its an expensive hobby no doubt. The money factor made me think about just trying all motor on my stock d16 engine, but then a stroke of luck hit me last night when my friend told me that he could get his hands on a gsr motor (the last year before the rsx came out) for atmost $500. And its a brand new, never been raced, never been driven hard and is so clean you can eat off it. What do you guys think? Should I take him up on his offer?
