Audi 2.2 throttle body on a Mk1 Golf

Am I right in thinking that an Audi 2.2 throttle body is an upgrade for the Mk1 Golf Gti?
What's involved in the conversion, any other parts needed?
Anyone done this and noticed a difference!?

 

you need the warm up regulator off the 2.2 or the 2.3 you could also use the 2.3 TB too,

 

The bit with the 2 braided hoses on the front of the block?

 

yeh thats the one

 

Jolly god, those are the bits I got from the breakers on Saturday, just need to dremel out the inlet now

 

UPDATE.

I fitted the Audi TB and warm up regulator, but I'm slightly confused as the inlet didn't need any reshaping at all, it was exactly the same shape as the new gasket & TB, I wonder if this car's had this done before

 

Do you mean the audi80 ones?

You should be able to tell if it's already been done, as the casting lines will have been removed where the manifold was opened out.

 

It was from a 1989 Audi 90, looks just like the one pictured in the first thread

 

Seems I need to connect a vacuum feed to it still though, I might use the MFA one as the MPG bit doesn't work any more.
