300zx help, Updated: pics on pg 2 Options

[samir0189]

Found a great deal on a 1990 nissan 300zx, t-tops, 2+2, non turbo, mint. 74000 miles on it.

Just wondering if anyone knows what the common problems with this car are? What to look out for, etc?


price is not the issue so don't worry about that.

Thanks in advance..........

I've worked on exactly 2 of those from that vintage and they just seemed to have any of the normal problems a car thats 20yrs old would have, which was any of what I had listed above. one was a beaten to hell daily driver than was owned by a 65yr old black woman on welfare and was about as safe as golfing in a thunderstorm ontop of a hill. the other was a well taken care of black one that was nearly mint inside and really nice outside as well. both had all of the rubber parts rotten, every bushing, line, hose, caliper hoses, etc all rubber was rotten. it just goes with age no matter what you do, it dries up.

the nice one needed a fuel pump and then plugs and then had stuck injectors and then the wiring to the injectors...ugh. the insulation on the wires was soo brittle and heat cooked that it all cracked off the wires when I unplugged an injector.

the nasty one...was rusted out, front brakes barely worked due to seized calipers/slides, the rear brakes barely worked for the same reason, 2 struts were frozen, ball joints and tierods were about to fall apart, rear diff leaked very badly, every rubber was rotten.

yup from what i understand the injectors do stick and the one im looking at has one stuck, in 1993 they seemed to correct it so if i end up getting it i might swap them for 93+ ones. i read the wiring does that same crumbling as well.

Ill have a better look at all the rubbers later today hopefully they are in decent condition... i hadn't read anything about that on the Z forums, but that's exactly the kind of info i was looking for. Thank you. Either way its normal for rubbers to dry up, its happening on my 6gc as it is.

Im gonna look at it later today and maybe post some pictures here.
