zero Posted March 23, 2002 Share Posted March 23, 2002 where is the weight difference between the 240 and 280z made. I ask this because I am looking for one and 280z's are easier to find but 240's are lighter and i am looking to make a very light car. thanks Quote Link to comment Share on other sites More sharing options...

staledale Posted March 23, 2002 Share Posted March 23, 2002 Wiring harness, doors, and reenforced frame(unibody) plus the above. There is quite a bit more wiring used in the late model Z to meet both safty and smog laws. The doors have heavier beams in them, and there is reenforcements in the sub frames for the bigger bumpers. There is also a frame rail that runs the whole way back the floor that my early one dosn't have. Quote Link to comment Share on other sites More sharing options...
deMideon Posted March 23, 2002 Share Posted March 23, 2002 I have a 73 240 and a completely disassembled 280. It really amazed me how much stronger the 280 is built. the sub frame is significantly larger and longer, and many more reinforcments in the uni-body!

DavyZ Posted March 23, 2002 Share Posted March 23, 2002 I keep tossing around buying the title to a rusty 240Z and swapping over the Vin#'s and stuff to a 280 roller--not very legal, but a 280Z would actually be the car of choice for me--they are stronger, cheaper, and generally in better condition. Oh well, I'll keep lookin'. Davy Quote Link to comment Share on other sites More sharing options...
Len Posted March 23, 2002 Share Posted March 23, 2002 Oh Davyz! I think we had this conversation a few months back Lets not go there again! Len Quote Link to comment Share on other sites More sharing options...
Len Posted March 23, 2002 Share Posted March 23, 2002 In the JTR book in chapter 17 page 1 he breaks down weight difference between 240 and 280. The 520lb. difference was 175lbs. bumpers, air conditioning 60lbs.; as Staledale mentioned doorbeams; electric fuel pump 5 lbs.; rear anti sway bar 10 lbs.; R-200 diff. 16lb.; 3 row radiator, cat converter & heat sheilds 25lbs, Fuel injection,more sound deadening, fuel line insulation,vapor recovery systum.................I agree with Davy; pretty much improvements for the better. Stuff you don't need you can remove, like the bumpers, vapor stuff. Also you save work by not having to install a R-200 rear end, electric fuel pump, Fuel injection friendly fuel tank Quote Link to comment Share on other sites More sharing options...
zero Posted March 24, 2002 Author Share Posted March 24, 2002 so basically if i plan on making a v8z, the 280 would be the best choice and would work with less strengthening of the frame, if any. also one more question, if i have a 280z do i have to be smog legal, because i know with a 240 it predates the laws and you can be as dirty as you want. thanks alot Quote Link to comment Share on other sites More sharing options...
Len Posted March 24, 2002 Share Posted March 24, 2002 I personally kinda favor a 280Z for a Hybrid because of all of the above reasons. Regarding your 2nd question. You do have to abide with the smog emission regulations enacted during the year of your car. So a 70 240z has less smog stuff required as compared to a 78 280z.
