There isn't much on a 16V in the way of emissions control that is worth 
removing for performance reasons other than the catalytic converter.  Sure 
there are the OXS sensor and evaporative emissions controls, but they don't 
really hinder performance.  You can certainly lose the cat without hurting 
anything other than the atmosphere (heh).

You can remove the charcoal canisters and the other crap if you just despise 
it all and want a small reduction weight.  I don't think it'll affect the 
fuel injection at all as long as you plug up or re-route the disconnected 
vacuum lines properly.

There are limits to what the KE-Jetronic fuel injection can deliver, although 
where those limits are is debatable.  Going to carbs would only be worthwhile 
if you exceeded the capacity of the stock fuel injection (which is probably 
good for 160+ hp or so), IMHO.  (I suppose I should confess that I am fond of 
fuel injection and biased against carbs for a number of reasons.)
