If they're injectors designed for use with a 2.0 8V motor and you're running a 2.0 8V motor they really should be about right, unless I'm missing something here.....
A slightly hairier cam and a flowed head with the injectors might improve performance a bit, but you really need to be running a lambda on the management, so the ECU can manage the mixture properly - for that you'd need a Euro loom and chipped ECU.
