speedo calibration

[warpz0r]

hi all

got a rb20det in a vl and as you all would know the speedo is out.

is there any device that can be connected to the speed sender unit on the gearbox that will convert the speed to what it should be?

thanks

Maybe try for a sender unit out of a VL gearbox. They are usually a gear set - a worm gear on the output shaft, and a helical gear on a removeable unit. The helical gears usually come in a variety of "teeth", so you can change them around to get the right ratios.

the gear unit doesnt fit in the hole...

and doesnt the determined speed come from the diff?

as it doesnt allow the wheels to turn as fast as a skyline diff?

my diff is 3.45 skyline is like 4.3 isnt it?

The gear ratio of the speedo drive takes account of the diff ratio.

Check the Yellow Pages for "Instruments - General" for people who can re-calibrate the speedo.
