This mite be a re post so if it is I apologize I was thinking about it and what's so different from the "N/A" supra and the "twin turbo" once? I know the fact that the "twin turbo" has 2 turbos and they are 6sp or auto, but I mean can you make an "N/A" turbo? Like built the engine and put together a single turbo kit? Or can you just put together one with the stock engine? Do you have to swap the engine? Is it even worth it?
