I am new to Hondas. I just sold my Mazda Miata and bought a pretty mint 89 civic dx hatch, it has a D16b2. I have been noticing the possibility of interchanging OEM parts from different models to gain performance. What parts and from which honda/ acura models/ submodels will benefit my car? And if you know, how and why as well. ( like to know the technical side) Also any drawbacks.
