Could you be clearer about what the outputs of the design projects are? Is this a full concept design where the output is a complete design ready for manufacturing and assembly? Or is this simply a concept brain storming exercise? I am assuming you are not actually going to design and build an internal combustion engine.
Since this is a forum for the Simscale simulation software, perhaps the most relevant thing to ask is how can the software be used to help you in your design. Examples are to optimize the aerodynamics of the car, to make sure the brakes do not overheat and to check the rigidity of key components. If you can ask me a more specific question, I will happy to give you general engineering advice, but currently I don’t even know where to start.
@jousefm I have noticed quite a few questions like this where the poster asks for general engineering advice rather than specific simulation advice. Have you considered opening a forum section for this type of question?
