well you have a 280zx which is a S130 car.. total different car then what i have.
they still make air dams and etc for it though.
the green one has a 240z style air dam w/o air ducts (its fiberglass).
the blue one is a 280z style with air ducts (its platsic, well not but u no).
both can be bought threw MSA www.zcarparts.com
you can also get 280zx stuff there too, but my stuff wont work for your car.
the intake manifold on the blue Z is a 1975 only unit.
its a N42 intake manifold which is alot cleaner, has no webbing between runners and has no egr crap. I made mine as smooth as i could get it with little time spent on it and then i powdercoated it.
the wideass wheels on the blue Z are old old oldschool Ronal Racing wheels, they stopped making them in the late 70's.. it was a lucky find for me thats for sure, the rears have a -30 something offset lol.
the green Z's wheels are 17x11 rear and 17x9.5 front CCW wheels, they were custom made to my specs... i looooooove wide wheels on my Z's.. hell even my black mesh enkei 92's thats on my blue Z right now is 15x8, which is wide for those wheels and very rare. just sucks cuz it takes lots of money to just fit wide wheels on a old Z.
