Lsd install question
 

Bought a used factory lsd for my 88 Carrera and there seems to be nowhere to hook up the speedometer ? I believe it came out of a 993 . Did 993's have a different Speedometer hookup ? Is there any workaround for this with my older carrera ? Drilling some holes ? thanks for any input.

Attach one of these to the fender, and learn to estimate speed by how fast its spinning....:D

....more seriously...
I had a similar problem with our Burg 944. It initially had an LSD tranny from an earlier car, whose speedo was mechanical off the front wheel. The later trannys have an electronic pickup. I eventually bought a later non-LSD tranny with the proper pickup that the car could plug into. The earlier LSD tranny went into the race car, which is using a GPS based speedo.

Not sure how the 911's compare speedo-wise. But an option for you might be a GPS based speedo. Is your car using a mechanical or electronic speedo? If electronic, there are some adaptors I've seen online, that can use a bolt or some other spinning reference object, but getting the electronic signal to match the speedo is not necessarily easy.

This would be a more appropriate measurement device:

Scott, the 993 speedo ran off an output from the ABS control unit who's input was the R/F speed sensor.

Stick a TomTom on the dash.

Hey.. what's up Chris Prack..!

I don't know. Just hanging out and enjoying the show. Pass me a beer when you get a chance. :)

My mechanic machined the holes for the speedo. says it is working fine. great improvising...

I had to do the same thing with a Quaife diff once. Three holes for the aluminum ring.
