Want this question answered?
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.
yes
Nope, im looking for it also but for a Datsun 280ZX Nissan and Datsun are the same thing, however if you have the Chilton's Repair Manual for the NISSAN Z&ZX 1970-1988(which you should) I believe it's number 52800, you can find the vacuum diagram in section 4 page 26 That diagram is for a N/A 280ZX and only for the emmissions. I need a complete diagram for a 280ZX Turbo, 1981. I have the Automatic Climate Control and it is a California model. Can anyone help?
No, not in 1980. Nissan first offered a factory turbo as an option on the 280ZX in 1981. It was available that year only with an automatic and a 2 passenger car. In 1982-83 the turbo could be purchased with 5-speed manual, auto, and in either 2 or 4 passenger versions. The L28 turbo engine can be installed in the older model Z-cars though.
idle air control valve needs work. either clean it inside and out or replace it. could also be the maf sensor
firewall passenger side just below the spark plugs
on a Nissan 280zx from 1979 to 1981 everything on the entire car is the same even down to the body doors and hatch
Negative battery cable - a solid metal part of the engine
yes. it has the L28e or L28et. It will fit in any of the Z's. If it's turbo and the other tranny and rear end you have are for a non-turbo then you need the turbo tranny and rear end
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 Arturo 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. Curtis
Firing Order of Nissan's L-6The firing order of the 1982 is 1-5-3-6-2-4 (1982 Datsun 280ZX Service Manual, October 1981 edition), all L24-L28E engines use the same order (240Z-280ZX till 1983). In 1984 Nissan changed to the VG30E for the 300ZX which has a firing orde of 1-2-3-4-5-6.
Yes, nothing really changed bodywise until the 1982 model year.
