=== >Manual Transmissions ===

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, while the FS5R90A 5-speed found in the 1983 280ZX Turbo is a "wide ratio" transmission. Close ratio transmissions 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.
