I'm working out how to attach my v6 throttle cable to the northstar throttle body on my l67 swap, I bought the bracket from zzp and modified it so it attaches, but the actual end of the cable is where I'm stuck at the moment. I've seen recommendations to use the 87-88 4cyl throttle cable, but I'd rather not try to track one down if I can help it unless someone has one to sell on here.

The half moon piece is plastic so I can't weld a nut to it like I've seen done on the stock 3800 throttle body. Anyone done this before? Pictures and threads seem sparse on this. Two of my current ideas would be to either drill a hole through the plastic on the side and use a bolt or if I pull the cable all the way through the half moon piece I can use a screw to attach it on the flat part. The latter however opens the throttle a degree or two.

Any help or pictures would be appreciated, if anyone wants further clarification of my ideas I can take pictures.

Just went through this on my swap. I ended up drilling a hole in the plastic rotating arm and secured the cable end with a bolt. Don't have any pictures of it yet, but measure it out and you should be fine.

I also do this on 3800SC swaps and it works fine but I fabricate the throttle cable bracket from a piece of the Fiero bracket and some L channel. The only fine point is making sure that the cable is tight enough to open the throttle body all the way at WOT. The cable should have very little if any slack in it.

Thanks everyone, I'm working on planning it out, don't want to screw up the brand new throttle body, if anyone could snap a couple pictures that would really help, if you don't want to mess with photobucket, etc, you can just email them to me, or picture text (just pm or let me know in this thread and I'll pm you my number) I'd appreciate it.

Here is the item I used. I got it at a local auto parts store.



I had to slightly open up the hole in the TB. I then cut the factory eyelet off the cable, pushed the cable thru this thing, made it snug, then tightened down the screw. Its been fine for like 5 years.

I've searched, and can't find any good pictures anywhere. Here is one showing the modified cable bracket. I just opened it up a bit for the fiero throttle cable to fit through.


Can almost see it if you look close here..


This is a stock throttle body, but same idea.




Link to when I first did it with stock throttle body. I reused cable/barrel when I upgraded to the N*:

Just a reminder to anyone using this method is to periodically check and make sure the set screw is still tight!

My dad did the same thing on his car and it came out on him one day while he was out driving

That is a good thing to keep in mind, I went out and bought one, when I was sizing up where to drill the hole in the plastic as I was going to insert it sideways I noticed it was just long enough to reach the recession in the bottom of the plastic half moon (I wish I knew what that piece is called).

So at the moment, I cut the metal eye part off the stock cable, and inserted it into one of those "Dorman - Help Cable Stops" as they were called and put it into the recession. It is tight enough I had to pull the cable out of the bracket to put it there. Here is what it looks like:



Personally I think it works, as long as it doesn't come loose on the cable stop, I was thrashing the gas pedal to make sure it wasn't going to pop out, like I mentioned, to get it out you have to take the cable off the bracket. I took some vice grips and tightened the cable stop down for now. If it's a terrible idea just let me know, but it seems functional. Also, couldn't you use some lock-tight on the screw?
