Forte Throttle Linkage on Complete Car

[FarmerDave1321]

Has anyone accomplished or have advice otherwise on installing the forte throttle linkage on a completed car? Photos would be great...

Thanks in advance!

Yes it is doable but you have to like being a contortionist. I did it because I did not like the cable arrangement.211647

I can't imagine how un-fun that would be on a complete car.

You need to drill the holes for the cross bar supports close to the main frame that goes across the dash chassis. Reason being, if you drill too high the upper linkage lever will hit the top of the footbox.

I did mine in a completed car (Mk III) as well. I am quite slow when I work so it took a weekend. I wish I had started yoga before....

What you cannot see in the picture is inside the footbox there is a linkage lever that faces up on the end of the shaft that goes through the footbox. It swings through an arc form about 10:00 to 1:00 and if the supports are drilled to high above the cross frame it will hit the top of the footbox. I drilled mine about 5/8" above the cross frame. A linkage rod goes from that lever down to the foot pedal. If you have a stock firewall it needs a fender washer on both sides of the firewall. for the inside I ground a flat side on a fender washer so it would sit close to the cross frame and not hit. That was the only pic I had of the linkage.

Yeah this is the part that I was curious about. The components in the engine bay seem straight forward enough, but getting the rod from the pedal hooked up looks like it's far from fun with limited access.

I drilled out the rivets and removed the top of the pedal box - made for easier mock-up and installation.

[ggunter]

If you remove the inspection cover on top of the foot box, you can get some view of what's happening and some limited access.

I did it on my MK2. Have multiple videos on the install in my build videos.

I just finished mine on a MK3 Challenge car. It was an extra challenge as my doors don't open. Laying upside down, feet in the air under the dash was less then fun. But doable. I took out the driver's seat and removed the steering wheel to give me more room to work.

[ggunter]

Wow! Upside down in that footwell that is real punishment.

I was looking through the forum today and saw a picture of Brew city Cobra's throttle linkage with a better picture than mine that includes the inside linkage. 211681

You guys are the best, thank you! Pretty sure I have a really good idea on how to approach this now.

[CraigS]

Do yourself a favor. Before you start do this. Step #1. Remove the driver's seat.

I am considering doing just the opposite, going back to the cable linkage. My MK4 has the Thompson pedal and Forte linkage, but the previous owner installed the levers in the direction so that the carb throttle shaft is pushed rather than pulled toward the firewall.
I have drilled and pinned the shaft to prevent slippage, but I still cannot get enough movement to open the secondaries. I have run out of adjustment on the threaded rods and nothing has worked.
As indicated these systems are impossible to work on in a completed car.
So, I am contemplating ordering the stock pedal assembly from FFR and going that route.
Good luck with your project.
