Hi everyone, I heard about a 92 NSX for sale, but it had an upgraded tranny to a 6 spd. what would be the advantages (if any) to do this?
Welcome! First of all, welcome. I thought you were the real car guy
You might want to consider changing your handle to avoid confusion.
As to your question, yes, there are lots of advantages to a 6 speed tranny on an earlier NSX.
I have a 6 speed tranny on my 91, and I can tell you it is very sweet. I drove the 5 speed and it doesn't feel as "responsive" as the 6 speed. The 6 speed has better gearing for most conditions, and is just more fun to drive because it feels so flexible. A 6 speed transmission costs $8000+ to upgrade to, so it's a very pricey upgrade, but worthwhile, if you have the money.
Also, you won't have the "snap-ring" issue that the earlier NSX's may have.
