The stock and Neuspeed/Audi TB have the same primary. The difference is
in the secondary. The stock diameter(as measured on my 85 8V) has a 44mm
secondary. The Audi/Neuspeed unit is 52mm. This 8mm difference equates to a
little more than a 1/4 in. And they do have slightly different shapes on
the intake boot side, but the Neuspeed one will still fit. So it sounds
like you should upgrade. But unless you just like pissing your cash away,
I'd get one from a junkyard for much cheaper.
