Default 550cc vs 740cc injectors?

If i want to run 350 - 400bhp in the future, is there any reason why i can't oversize the injectors for my current needs? i.e going for 740's when 550's will do?

Cheers

Dave

None at all , have had a car running around with 740's at the 400bhp level for 6 months knowing that a 450-480hp 2.5 conversion would follow....

should be ok yeah, making sure its mapped accordingly, or else the car will run very rich, bigger injectors should be able to run a lot lower duty cycle than smaller ones for any given load placed upon them too

Going back to the original question - you say you want 350-400bhp in the future, why do you need 740s for this? 550s will do well over 400bhp.

He had been offered 740's and is having difficuly getting hold of 550's so he wanted to know if using 740's would cause a problem?
