While we will be running the Toyota 5 speed in the TR4 at Lime Rock that ge=
ar box and engine are slated to go back in the BajaTR3 afterwards.  The mot=
or that is being built for the TR4 is being mated to a 4-speed TR4 box that=
 has been order.  Trying to determine what gear ratios to run in it.  Will =
have both a 3.71 and 4.11 final drive and the motor turning over at 6k with=
 about 175 hp at the rear wheels.

Currently the Toyota boxes we have are running...

1st           3.950                    3.830
2nd          2.140                    2.060
3rd           1.38                       1.430
4th           1.00                       1.00
5th           0.810                    0.840

Anyone care to share the hot setup for a 4-speed TR4 box?
