What would the hp difference be. My mechanic said he can get my whole engine port and polished like he did is 89 accord. Finding the other parts wouldn't be that much of a problem either, but I am also looking at long term. I know turbo is wonderful but they say it is a Bi%^% to keep up on. Does the same go the NA?? I know price difference the turbo might be should be more, but the way people are running today, i am going to have to get the turbo to stay in the game.
