Yes , that's very true. I guess I will find out when I put in the 5speed tranny. Maybe someone could suggest me a differant rear end?

Thanks everyone for your inputs, I'm trying to find the tranny that has the longest gears, because I do alot of highway driving.if I'm not mistaking it's an (FS5R90A )now if the car is slower on city driving, I just won't shift into 5th.

Thanks 78zcar blue

Thanks SteveJ this what I found, it might help someone else like my self:Datsun/Nissan made several 4 and 5-speed manual transmissions available in the second generation Z car or S130. The 1981-1983 FS5W71B is a "close ratio" five speed transmission where the FS5R90A 5-speed transmission found in the 1983 280zx turbo is a "wide ratio" transmission. Close ratio transmissons are preferred for road racing as they allow the driver to maintain a tighter rev range between gears compared to wide ratio versions. Finding the "optimum" transmission for your car all depends on what you are wanting from your car. For most people the "best" transmission is what is already in your car. You can tell the difference between the FS5W71B and the FS5R90A by the shifter mounting.

I own an 83 280zx 3 speed. I would like to do a five speed swap because I ejoy driving a manual car, I feel more ''connected'' with the car. The only thing that I'm afraid of is that my z will still ride at high rpms going down the highway. I travel 60 miles to work and back everday. My z at 70mph is at 3500 rpms.. A little to high for my taste. If I were to change over to a five speed, will the top end speed increase? Thus lowering my rpms ? Btw my car has stock tire size, not smaller diameter wheels. Any input will really be thankfull.

Thank you very much guys I really appreciate the information, I think I came to the conclusion, that the small harness that has a positive and negative wire was faulty. It wasn't making a good connection so it was causing a bad connection and it would melt and smoke.

Hello I'm new to the site. I was wondering if anyone could help me with the fallowing issue I'm having: I bought my first z (83 280zx) last month and the alternator was overcharging. I went and got a new one, and I tested it before installing it on the car, and it was good. Now for some reason I think somehow put thenwires on wrong. There is a white cable wich is the positive, and off that there's a thinner one. That thinner one runs to a little cylinder like thing wich is grounded to the alternator.Then the is a harness wich has two wires on it. As soon as I started the car smoke came from this conector and it melted ... Can anyone assist me with any info, I would greatly appriciate it.
