I have a 90 prelude 2.0 SI. It has the 2.1 dohc b21a1 motor. My car is in excellent condition. It rides and handles very well. I have read about the problems with this motor, but mine is in good shape. I am interested in improving its performance. I am new to this Honda, but I have considerable experience in mechanics and electronics. Due to this motors reputation, I am not interested in high dollar mods. However, I would like to make the most of what I have. Any tips on performance tuning or low cost mods would be greatly appreciated. Thanks, Tim
