I have recently have gotten to a settlement with a private owner of paying monthly for his 300ZX, along with a down payment. It's my first car and I am pretty excited to meet with the seller early start of the week. Anyways, I know of the base 300ZX, 300ZX TT, and the 300ZX 2+2. Though, I never heard or found any details on the N/A version. What is the difference? Is it a slightly upgraded engine over the base 220HP one? What does N/A stand for? Thanks!
