Wow. That is odd they decided to number it like that. Just to be be totally clear, NA1/NA2 isn't *just* the engine designation. Even the service manuals list those digits as "body type", apparently that includes the engine type on the NSX. The following two digits designate it as manual (15) or auto (26).
Ah grasshopper, you have a service manual and are reading it. Good start.:smile:
You will find more that is odd as you continue if you are paying attention and it seems you are!
Bear in mind, the manual was written way BEFORE they had a NA2 engine or a 2002+ model and such might of not been anticipated when they chose their verbiage for the translation. You will find as you continue your studies that the manual has errors and information that is outdated as time went on and never corrected and passed from the first edition to the second. LarrryB, Pres. of the NSXCA and mechanical master, and I have noted and discussed them on occasion.
If you show up to the NSXPO2011 and join us at martini time we can discuss this some more.:biggrin:
There is NO chassis change. There is just one chassis. Except for the addition of a few reinforcements when the T, the removable roof panel, was introduced and slight modifications(a hole cut, small bracket added and some pieces at the right inner quarter) for the fixed headlamps and emissions pump, the chassis is the same throughout production. Same metal gauge, grade and construction as well.
It is delightful to have a new member who is obviously serious and earnest is his pursuit but before you feel too confident quoting scripture about this car you may consider there are some who have been studying it with your verve for many years before you arrived.
We have cut, unbolted and taken them a part and bolted, welded and put them back together again and then went to the fellows that made them to find out even more. Every time we meet them we have a new list of questions.
There is more to learn especially as parts supplies dwindle, disappear and replacements/repairs are needed and our combined knowledge and sharing as a community will be essential to the cars survival.
I am absolutely sure you have much to offer and will be a asset to our community. I can tell I already like you. Again, welcome aboard.
