from memory ( 10 years) when i did this it was like the third one down. it was off an audi. you need to make sure it has the pipe on it as i bought one which didnt off a 16v i think. the third one down has the pipe shown. hopefully somone who knows will come along soon!

This TB is the closest to what your looking for. You can strip the linkage from the original TB and refit to the Audi item.

Thank you very much does it need or is there anything missing like part from the smaller throttle body circle end out of the side of this Throttle Body like a brass part or a tube or does our mechanics take it off the throttle body which is on Sally ?

If your running the standard distributor then it will need the vacuum advance port near the idle adjustment screw. When it stops raining here I will try get you a pic ( and part number ) of some of the bodies I have...

No I'am running the standard distributor so we will need the vacuum advance port near the idle adjustment screw.

Think i used an Audi 80 5 cylinder one many year's back. The inlet needs to be filed to suit throttle body. Some 16v throttle bodys do have the vacume pipe on the rear again there a audi item, early type 90s

I've not done this mod or up on throttle bodies but does the number on the flap mean the size?
As the one in the link above has the same No.14 on the flap and looks the same size as my standard DX engine throttle?

The number on the flaps (butterflies) is the bore of the throttle body.
I assume the numbers on this on are greater than the standard one on your DX ?
when you fit it to the inlet open up the butterflies and your see a ridge around the bore holes , as manifold is to small. This needs to be flied out.

Managed to wade thru the shed junk....
Small vac port for running a vaccy advance dizzy..

Image

Ports left undrilled, some of the other bodies had a breather port about 14 mm drilled. Some are threaded and I just screw in a sealing plug ( tapered thread)

Image

Unsure if there is any coding to these numbers...
Image

Original bores are 35/44 larger body goes to 35/52. Velocity tuning in the states modded bodies to 56 mm but pretty sure that business is now gone.
You likely will need to change some of the linkage for the throttle cable and can dump the switches if not needed.
Other bit of the mod is to locate an adapter or have the flange on the manifold welded so there is a bit of meat between the bigger bore and edge of manifold and the bypass port for the idle adjustment, they both run with very little sealing area to the outside of the manifold ( potential air leak later down the track ) Have to take a snap of the modded manifold on Valeries cabrio..
