Hey guys. I have just got my new swap in my 1990 240sx with a 2jzgte engine. I was told that it is possible to get the stock speedometer to work (mph gauge, rev gauge, temp gauge). Is it possible and how? I had already changed the speedometer on my car from a 93-up 240sx that can read the sr20det swap I did before (ka24e to ka24de speedometer). I want to have a clean swap and use the speedometer in my dash rather than buying a huge tach and bolt it on the side. Any help or suggestions would be great.

MOST people use the dakota digital speedometer and tachometer signal interface boxes. they can be had for about $80 a peice.

you will also need the Dakota Digital 8K magnetic pickup (assuming your running the R154)

then you will need to recalibrate the boxes (which is kind of tricky) My Tach works just not the speedometer (yet)

Thanks a lot. Kudos
