That's actually not a bad idea. I'm in Oklahoma. And I've thought about calling DA to ask some general questions. By the looks of the FB page, I'm not sure whether I'd even get anyone on the phone as busy as it looks.
I'm not sure if you're talking about Jinks suggestion or what I had done, so I'll throw out two more NSX experts you could try to talk with:
Autowave (CA) and Applied Motorsports (CA). I highly recommend each.
Obviously, a lot of work is subcontracted out for these engine rebuilds. The NSX experts dis-assemble, supply the parts and the specs to the machinists or specialty shops, and then re-assemble. Rightfully-so, there's some markup involved for their efforts and knowledge, but for those of us that have some mechanical skills, knowledge, and are looking to learn more, it can be a bit frustrating.
DLC coatings on piston wrist pins for normal engine rebuilds is rare. Even then, I haven't heard of anyone else do it for the C-series engines. As such, if you suggest it to others they will probably dismiss the idea and say it is unproven, unreliable, or too expensive. Well, I've been at 550WHP on a custom twin-turbo build for a few years and about 7500 miles without any problems. I have a Canton oil filter cartridge that makes it easy for inspecting what's been filtered in my oil, and there have been zero indications of any DLC flakes. Calico coatings assured me it would be fine for my application and it has so far. You'd think they would know :wink:
Good luck on your build.
My mild build was sort of documented here:

I'm not sure what happened to the pictures, and I eventually stopped updating it since I was the only one posting in it... but there may be a few good tidbits of info or at least some good links to other interesting info.
