Mark, Here is some of your answer, compliments of the Brindabella Motorsports club with some of my comments.
Ratio sets for the "option" boxes (Nissan Motor sport boxes) The F5C71B, same case as the 240K. Steel syncros Option 1 1 2.818 2 1.973 3 1.470 4 1.192 5 1.000 Rev 3.382 Option 2 1 2.348 2 1.601 3 1.296 4 1.138 5 1.000 Option 3 1 2.192 2 1.601 3 1.470 4 1.138 5 1:000 Rally 1 3.321 2 2.270 3 1.601 4 1.240 5 1.000 The above are rare 1:1 5th gear close ratio clusters. They were always every expensive. These days unobtainable and if found extremely expensive for well worn (motorsport use) boxes. Great ratios for motor sport use, if you can find them. The K and Z boxes are K box, or Zed WR, Brass syncro 1 3.321 2 2.077 3 1.308 4 1.000 5 0.864 CR Zed box, steel syncro 1 2.906 2 1.902 3 1.308 4 1.000 5 0.864 The F5C71A, otherwise known as the Sports 2000 box, in the short tail, and the early zed box in the long tail. They have a flange drive at the rear and need a tailshaft with a slip joint in it built to suit. These boxes can be used in 1600's in historical trim. These are a steel syncro box Standard 1 2.937 2 1.858 3 1.311 4 1.000 5 0.852 Option 1 1 2.678 2 1.704 3 1.262 4 1.000 5 0.852 Option 2 1 1.858 2 1.388 3 1.217 4 1.000 5 0.852 I remember Hollinger Engineering made a close ratio 1st, 2nd, 3rd cluster for the 240K case. Cant tell you how to track these down. ----- Original Message ----- From: "Mark Overend" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, May 05, 2005 1:50 PM Subject: Gearbox > G'day, > Does anyone have info on gearbox ratios for Datto's, i'm looking for another gearbox.
