im wanting to know what the longest geared rear end would be for the R180 rear end. the race track i attend is a VERY fast track and i dont want to run out of RPM's halfway down the straight? help me please

3.36 is the tallest gear ratio I know of. It was also stock on manual 240Z's so is probably the most plentiful R180.

With a stock 240Z 4 speed and 3.36 and 225/50/15 tires you're going to be gear limited to 153 mph. You'll never get there with anything close to a stock Z though.
