ok, i read MichealDealney article on Engine Package: Swapping Parts for power at least 4 times, and read up on a few other articles. however, i am still i little confused. I want to raise my CR in my ls, by swapping b16a rods into my ls since its a direct fit. this willl raise my CR but where will my power come in? more low end? more high end? or will i simply have to dyno it. also, after the swap, since my car is OBD I, im guessing i should take it to the dyno anyway and reprogram it? what are the effects if I didnt take it to get tune/reprogrammed after the swap?
