HO Upper and TB

[GilroyRacing]

I just read mrltd's write up saying

"The 2 modifcations needed:
The linkage arms on the throttle bodies need to be swapped. It's easy and straightforward. Grind, swap reattach with screw, JB weld, or actually weld it."

Does anybody know where I can get a write up with some pics for this process?

I am going to be doing this, this week and would like to have it figured out by the time I actually do it.


thanks.

If you look at the linkages, you should be able to figure out what it means....


Grind the mushroomed part off the linkage, gently pry off the linkage, swap linkages, bolt/weld/whatever to mount the linkage on the new TB...

H.O linkage on the left, lopo on the right. Have to grind both of them off and then swap the lopo onto the HO one, then tack it back in place.



Difference in the throttle bodys



Lopo linkage on HO throttle body



Lopo EGR spacer on left, HO on the right, before boring out.



Lopo on the left, HO on the right, after boring out.

Why not just drill 2 new holes? 1 for the TV bushing and another for an aftermarket throttle stud?

[mrltd]

Because it's easier to swap the whole linkage than to attempt to get the correct location for the stud and TV bushing. It's be pretty tought ot get the stuff centered, since you would be drilling into part of another hole...

What would you need to do for an '86?

We are going to try it since I can't find my 2 spare lopo tb's any where.

Junk yards around here want $75-$100 for lopo TBs.... im not paying that much!

You swap the lever.

Thats fucking insane. I have like 3 of them laing around, I'd just give you one if you lived by me. Or you go to the yard, pull off the TB, hacksaw the lever off with a little of the rod still on it so you can get it in a vice, and slip it in your pocket. $100 is a bullshit price.

[gadget73]

oh are they trying to sell them as a "fuel injection unit" or some bullshit like that? I've seen that before, it is BS,

Not really.....

I just lined my mustang TB lever with the lopo TB lever, marked the locations,drilled the holes and installed a Throttle Ball from the Holley Carbs TB Kit, available from jegs.

Once the original Throttle Ball is ground off the HO TB, the TV Cable hole is the only hole that will remain in the HO TB lever. The hole for the new throttle ball is drilled to the left outer edge of the old Mustang TV cable hole, and does not even come close to connecting with the old TV cable hole. The new TV cable hole is drilled slightly to the right of were the old throttle stud was, and since the throttle stud was ground off even with the surface there was no hole left behind from it, to interfere.

I just took my time with it, and it came out right the first time. Didn't even have to adjust my TV Cable.

i still find it easier to swap teh levers

[gadget73]

Maybe its the air tools. Makes swapping the levers a simple matter. Probably sucks doing it by hand with a file.

my first one was done with a bench grinder, craftsman dremel, and a borrowed tap and die....
