Electric or manual?

[caliber05]

Which NSX came with electric power steering and which did not? Were some 91's electric and some manual? Would it show up in the vin #?

 

[MANIACura]

In 1991 all manual transmission NSX's came with manual steering. The automatic transmission models came with Electronic Power Steering (EPS). You can see this in the VIN by looking at the seventh digit (right after NA1). If the seventh digit is "2" it is an automatic trans which means it has EPS. If the seventh digit is "1" it is a manual trans and has no EPS. (By the way all automatic NSX's are NA1 regardless of what year produced which means they have the C30A engine.)

1991-1994 with manual transmission didn't have PS, and neither did 1999 Zanardis.
All other NSXs sold in the US market have PS.

It is coded the VIN, as described in the wiki.
