I have a pair of 1980 280zx's 1 is stock 1 has a 60mm throttle body and I get average 29 mpg and 27 mpg the 1981 is the same L28 engine so should be about the same unless its a Turbo then I dont know and 1981 is the first year of the Turbo option

Checking my mpg many times for several years on my 1981 280ZX, I averaged 23.7 MPG. With the cruise control on 55MPH, I never approached getting 25MPG even when driving 100% on the highway. I don't believe the above poster, Arturo, is getting even 27MPG with his 1980 models, let alone 29MPG. I consider the 29MPG ridiculous. And no, I didn't have the "turbo option" on my 280ZX that Arturo mentions.

Yes, nothing really changed bodywise until the 1982 model year.
The 1981 Nissan 280ZX was available without a turbo (NA) and with a turbo. With the turbo Nissan only offered an automatic transmission for this year. It was the first year for the Z series to have a turbo.
The gas mileage of a 1981 Corvette can depend on whether it is automatic or manual transmission. With automatic transmission, it gets 15 mpg on the highway, and 21 in the city, but with manual transmission, it gets 14 mpg on the highway, and 22 in the city.
8 To 10 miles per gallon on HWY if your lucky.
4 1/2 US quarts
4,5 galons
yes, its the same engine l28e
Yes it will. Also if you have the 5-speed (borg-warner t-5), you can also use one out of an 80s Camero or foxbody Mustang.
I have a 1983 280zx, so I can tell you based on personal experience that it will run, however your mileage and performance will go down and it could damage your fuel system.
