Great app! But could use a some work.

Please add Diesel engines such as
5.9 liter cummins and the 6.6 liter Duramax. Also add more components like turbochargers and superchargers.
And maybe make the engine building feature more useful by having the option to change the valve train from 2 valves per cylinder to 4 valves. And more option like that. Thanks for the app. Please continue to add new engines.
