Hey, i was wondering if anyone would like to collaborate with me in making an engine system consisting of various inter-changable parts to make different engine configurations. As an example, you would have an inline 4 block to start with and you can then add different exhaust systems, intake systems and even down to switching out different fuel types. 

A lot of time could be cut out if there is already a solid but simple engine model out there so it can be modified instead of having to build one from scratch. Other people could then download ours to try their creations on it.
