How to run the throttle cable? (question for turbo guys)

coupe diem · 03-09-2005, 01:27 PM

I'm coming to the final stages of my swap and the little details are starting to haunt me. I was just wondering how anyone who has done the swap ran their throttle cable and linked it to the actual lever that opens the butterfly valve. On the 5000 it runs the cable down to the transmission and then there's all kinds of linkage and what have you, and on my old coupe the throttle it just ran the valve directly. So far i'm thinking that this is going to have to be a custom job, but if there's something i'm missing please enlighten me. Thanks.

From what I've seen you'll have to figure a custom way. But let me know what you come up with. I'm about 3 or so weeks away from hooking mine up

not sure i completly understand your issue... is there something more complicated on the other turbo motors??

It sounds like you have an automatic donor car because of how you describe the linkage from the transmission to throttle. Keep the bar coming from the throttle going to the first pivot point at the back of the intake manifold. Use your 4000 valve cover and throttle cable to pull this pivot similar to the stock 4000 throttle lever.

I used an urq cable but since my donor was automatic I had to modify the throttle end of the cable. The manuals look like your 4000 does. The autos have a ball and socket instead of the black cable guide and clip. To adapt the cable I cut one of the ball/socket ends off an automatic linkage bar, drilled a small hole in it near the socket, fed the cable through the open end and out my hole, then hammered the thing flat against the cable. It's held up that way for several years now.

My roommate used the 5ktq cable which works great at the throttle end but needed some sort of adaptation to the 4000 pedal.

Hope this helps.

Im not using my UrQ throttle cable or manual 5ktq throttle body if someone wants them cheap. Might make things a bit easier.
