Here is a model of a SR20DET engine block that i designed in Fusion 360, it has the correct cylinder bore and crankshaft size. It was rendered with a cast iron texture to give a realistic look to it
Best for in-game use and just modelling, feel free to add on to this model as id love to see it used in many different ways
