You should read your own information. Almost half of all NSXs produced till 1998 were 1991s lol. They are the worst year, and are plagued with the most issues(no offense decom, its still a nice car obviously). They are worth the least of any year.

Now as far as his modifications, nothing was done that wasn't tasteful, as well as reverse-able if he ever feels the need. Go be miserable somewhere else lol.

I've seen the production numbers, and there were a ton of NA1s produced. They are plagued by a few problems but nothing drastically more than the rest of the nsx's (there was a snap ring issue with some early 91's). But on the light side of things, 91's had the lightest chassis due to lower safety standards, and also the most rigid, because 95+ all went with a targa top (not including special order/limited editions ie: zanardi, type-r, type-s, type-s zero etc).
I haven't regretted any of the mods I've done, and need not worry there will always be stock examples you can find. What matters to me is that I'm enjoying what I have and everything I do teaches me something about it.

NAAAAAAAAAAAAAAWWWWWWWWWWWWSSSSSSSSSSSSSS!!!

Dude knows his stuff though...

You sound like a whiny bitch.

Not at all in my opinion...in My opinion...he knows his shit about NSX's...

do you plan on any force induction?
i like the NSXs for a while, only reason why i havent really considered getting one is because to be honest, they are pretty gutless. while i know they are a much better track car, the problem is i have no track around here to test it on.

btw hows the ride quality in this? is it good enough for a daily driver?

I daily drive it (except for snow) and its not uncomfortable. Have to be careful with driveways of course. I plan on supercharging this year but you gotta remember this car was released during the gentlemans agreement in Japan so Honda really had its hands tied power wise.

Got the wheel and everything in. Wired the cruise control successfully, horn works, and no airbag light.
