The question is why would you do this.
You should stick with whatever injector your tune requires to run correctly. If you're stock, keep with the stock ones. If you're running a bigger turbo tune, then use what ever the tuner suggests. Those G60's are probably low impedance OBD1 injectors too.
'00 Beetle, 1.8t T3S60, Brute Rods, Supertech Valve train (stock cam shafts for now), port and polished small port head, custom FMIC (pain in the a** on a Bug!), Bosch 440cc injectors, 3.5FPR, Catch Can, 2.0 Coils with Iridiums, Wilwood BBK, too much other stuff to list, too much $$ spent.
