Background:
I bought my current NSX in November 2017 from the original owner who had the motor build done by Shad Huntley at Driving Ambition. The motor had failed and needed to be rebuilt. In the effort of full disclosure the owner had been racing the car in the Silver State Classic. The build was completed 10/7/2015 when the NSX had 107,426 miles on it. When I purchased the NSX the mileage was just over 109,000. Roughly 1,574 miles were put on the motor after the build but before I purchased it. Some of those miles were break in miles and some were racing miles. I think about half of those miles were from racing.

I picked up the car November 6, 2017 and trailered it from northern California to southern California and from there I drove it back to Houston. The trip home put 1,620 miles on the car. It ran great the whole way home and never smoked or consumed any oil. I checked the oil every day of the drive. The previous owner supplied me with all the records from new, so I have the build sheet/invoice from Driving Ambition. I also called Shad to confirm that he did the build and that the invoice was correct. He confirmed that it was his work and that he had maintained this NSX since 2008. He said the motor is built for 600whp. Currently the car makes 417whp with the 9psi Comptech supercharger and Driving Ambition aftercooler. The motor has 3,400 miles on it since the build. This number might change a little as I do rarely drive the NSX.

Will be doing a K-series swap

Interested, where are you located? I'm in Canada, I am debating if I should go for your engine or go with sos 3.5l build (spun bearing on my 3.0 with stock bored sleeves).
 
I'm in Houston Texas. I have no problem getting it crated and shipped to Canada. Feel free to give me a call if you would like to discuss further. Thanks
 
Motor and clutch have been sold. Trans and Supercharger are out of the car and ready to go.

Supercharger will also come with the SOS big bore throttle body that I left attached to it.
