I am torn between doing a B18B ls motor swap or a B18C gsr motor swap in my 90' crx si. I recently had a SOHC ZC put into it, but with the increasing number of discontinued parts and the 332k miles in the car, i have defined my motor swap options to only these 2. Since they are an american manufacturer, parts will be easy access. What i am wondering is which motor would be better for my car. I do have plans for the tracks, but keeping it borderline street legal. I was told that doing the LS would require a suspension conversion AND axels... but what about the GSR? i know the GSR offers less hp promise than the GSR..... and now my mind is running faster than i can make sense... what should i do?
