I bought this 93 240SX with an SR20, but the speedometer does not work right. It shows higher speed that what I'm actually doing. Was there something needed to be changed or done at the time of the swap? Or do I have to get a new gauge cluster?

 

I know this is ganna sound really dumb, but are u sure it isnt KmH?

 

lol, no it is not dude

 

Just making sure haha. Could be your speed sensor is out of place and reading it totally wrong.

 

Where is the speed sensor located?

 

The Speed Sensor is on the right hand side of the tranny just at the end where the drive shaft comes in.

 

mines about 10mph off....but i got a 99 180sx pupkin and it had a nismo lsd in it and i think the final drive is different.


is yours open diff or a lsd?

 

mine is an open diff, and it is about 10 MPH off. But then also, maybe the previous owner had a the wrong size for the tires, they read 195/60/15, is it the right one?

 

Yea stock size is 195/60/15

 

actually, I think that the tire size is 195/60/15 front, and 205/60/15 rear, and I guess that is the problem. . I still might be wrong though.
