Bigger Nozzles Or Bigger injectors?

Hello!
Ive got a 98 seat tdi 90 (non pd) and I understand that the 110 bhp engine uses slightly larger injector holes .205 I was wandering whether I can just change the nozzles on my injectors or would I have to swap injectors completley.
Also where would I get injectors from? I can find nozzles for sale but havent been able to find any nozzles.

Thanks
Jason

any help would be greatly apreciated!

Buy some nozzles and get them fitted and balanced by one of the vendors on here, I'm getting the bosio pp764 nozzles from kermatdi and they're getting setup and balanced by drivbiwire and this should give me the extra 20bhp, I'm on a standard 90 too. The 110bhp cars use slightly bigger nozzles and slightly different tuning in the ecu from what I've heard but the 764 nozzles are good for 220bhp apparently.
