I heard rumor swimming around the internet that a guy from California's Bay Area took an NSX and swapped the engine for a 3.0L V10 Honda F1 engine and added a custom exhaust and intake. I did some research on a Honda ran site that such an engine does exist. Anyone have heard this or have more information on it?

I also heard of this. They were still toying with the design last I heard, but rumor has it that it is supposed to be a front-engine grand tourer.

what is the model name? is it still in the concept stage?

The NSX i was refering to was a late 90's, early 00's
