I'll be following this... Nice write up and you picked up a nice car for a great price. Nice early NSX's have been going for what you paid or more.
Frank at http://strutwise.tech/ in Canada does a fantastic job rebuilding and re-pressurizing the stock struts. They are better than when new when he gets finished with them. I just had him do all four of mine last year. It was about $110 plus shipping. My two trunk struts were getting weak and wouldn't hold the trunk up if it was cold or cooler. My engine struts where still okay, but while I was doing it I had him do all four. They really pop up and stay open now.
You already have new struts so you won't need them for a ling time. I have a 91 and just had the originals recharged. The only issue I read with the aftermarket struts were where the brake light wire bracket attaches to the strut, the aftermarket ones are larger in diameter and the clip doesn't fit like the original struts.
You can always search nsxprime.com forums for 1st generation NSX/s for lots of information. I don't logon to their site very often anymore. I mostly follow NSX stuff on FB NSX Prime, NSX Owners (for owners) and NSX Club of America (for club members).
You might want to become a member of NSXCA (nsxca.org). You get a quarterly magazine, plus this next year they are having their Annual NSXPO in San Francisco, CA Wednesday September 26 through Sunday the 30th. The track portion of the event will now be two days at Thunderhill Raceway, the 26th & 27th, with the social part of the event Friday the 28th through lunch on Sunday the 30th...
They select a different site each year, have various fun stuff planned and usually have a couple track days. They usually begin taking reservations for the next year even in February or early March, so if you think you might want to attend you should join fairly soon.
Somebody posted seeing NSXs for under or near $10k years ago. I've never seen them for that unless they were wrecked or somebody wanted you to wire them some funds electronically to some Western Union account (scammers).
Funny to me, several comments about converting a 02 & newer NSX-T lights to pop-ups. . . I've heard and seen so many wanting to do or have the opposite, purchasing a 02 conversion kit to turn their pop-up light cars to the 02 bug eye lights. I'm guessing so they look more modern. Personally I'm a pop-up headlight fan, but would keep a car original or slightly modified. They hold their value better.
If you want more power the CompTech superchargers seem to be used most often. They were installed by the dealerships and on the 1999 Zanardi Edition coupes they came supercharged from the factory.
You don't have to worry about the snap ring issue somebody had mentioned earlier. All first generation NSX's have the same snap ring. The issue affects some late 1991 and early 1992 NSX transmissions. Honda was using a three part tool to cut the case where the snap ring fits. They would calibrate the tool and make the cut and after ten cuts or so would recalibrate the tool. The issue came where the tool, since it was in three parts would go out of tolerance and cut a groove larger than it should have been. This left room for the snap ring to move and twist allowing them to break. Honda resolved the issue by changing to a once piece tool to cut the case where the snap ring fit. The issue affects transmissions within a range of transmission VIN's. And not all transmissions within the range are affected. Those cut right after the tool was calibrated or shortly there after would be fine. It's been 25 to 26 years, so hopefully most of them left will be okay. It's similar to Russian Roulette, some are fine and some may break. But I personally don't see it being a deal breaker. I believe I read somebody purchased a new case for $900 or so. I suppose it could break and leave you stranded, but so can a blown coolant hose (I know a transmission is more costly fix).
In my opinion you received a great deal. Barrett Jackson in Las Vegas October 19 - 21 just sold a 91 NSX for $71,500. The 2005's have always been valued quite a bit more, plus you have the final year of the first generation NSX, 2005.
There were only 248 NSX-T's made in 2005, 240 MT and 8 AT cars.
45 New Formula Red cars: 20 New Formula Red/Black interior, 22 New Formula Red/Tan, & 3 New Formula Red/Red interior.
I've had my 91 since March of 2008 and still love it. It's a very fun car to drive and where I live it breaks lots of necks.
I didn't mean to ramble for so long... thanks again for the write up. I plan to check in and see how it goes.
