If it's a throttle body injection system then they will probably work fine, though grossly oversized, it'll likely work fine. The one thing to check is that it can handle 6 cylinder timing (60* firing instead of 45*).
If it's a multi-port system, you would have to come up with your own intake with injectors and fuel rail, but any of the ECU's should be able to do 6 cylinder timing.
