So i want to ask which engine is the most powerful and the best. As far as i know, this is 2JZ, but i want to tuning my ford mustang and dodge challenger but this engine is not available for them. I know also one 1 engine is good too but it is not also available. Can you tell me which is the best for these 4 cars cuz they do not have 2JZ as an option
