If you have an eprom ecu you can have a chip programed for any size injectors you need. So your car will run like stock. I would just go big the 1st time.

No problem.
The only way to tell is to take the ECU out and open it up. You will see it in the corner. Go to vfaq.com. That site will tell you everything you need to know.
