have any of you modified your tailhousing for the jags that run kit for the cable driven speedo with a t56? is it easily done? got pictures of the steps to do it? thanks

or....
is the Cable X box that Abbott sells worth it? which is better. abbott says that there is +- 2% error in the speed, that isnt significant is it? i mean at 100 your speedo will read 98 or 102.
whats all your opinions? i really want to get this taken care of. thanks alot!

 

I just bought a t56 with ripper shifter for 800 bucks, so id also like to know if people went with the JTR mod (i have access to a mill and a lathe) or if the cable x ticket is the hot one

 

how's about a search? I have one and it works fine. They only sell you the parts now so you'll have to find somebody willing to tackle the machining if you aren't capable of doing it yourself (mill required).

I can re-host the pics if you want (on the second link).

 

thanks james, if you dont mind would you rehost those pics for a little while? id appreciate it. i guess the cable x thing is easier but im still thinking i want the JTR kit, id have to find someone to do the milling though.

 

they are back up.

 

I have the cable x box on my Iroc, but be warned they aren't cheap. I don't remember how much mine was exactly but I know it was a little over $300 or so.

 

i htink it is about 293 bucks, but the jtr kit is around 300 too.
how do you like the cable X?

thanks for the pics james!!

 

I like it alright, there is a little bit of lag, but that is to be expected I think. The worst part was ripping the dash apart to get to the speedometer cable, mine was being a pain so I had to end up pretty much taking the whole dash apart. Wiring it is a simple 3 wire operation. And then you just figure out how you need to set your dip switches with the manual they provide you. I went with the cable x box because I didn't have the time or option really of taking my trans apart and letting it sit to do the JTR mod. As it was my only car at the time.

 

i think i might go with the jtr mod. i just have to find someone with a mill who likes doing favors

 

Im confused with this cable x vss whatnot. Is the vss hooked up through the factory speedometer unit and then to the computer or is it a wire near the 700r4? Im doing a t56 swap on 88 5.7 iroc. what pulse per mile do i look for when i program it? any help would be sweet - i can seem to get a straight answer....

 

If you modify the tailhousing like the JTR kit, you will use the factory stock T5 VSS, either cable or electronic. If you use the Abbot Cable-X box, then the T56 VSS sends a signal to the box, then it turns the gears inside it which turns the cable to your speedometer.
I have a modified tailhousing like the pics in post #3.
