Mod the stock ones and save yourself some money. They will flow anywhere from 740cc and 800cc. They will produce a nice cone shaped spray pattern as well. Just make sure you get an EM that can control the extra fuel for idle

What kind of variation are you talking about? If you cut the caps off they'll all flow about the same. People have been getting various test results because of the various fuel pressures used while testing. The first test yeilded a flow rate of 740cc/min and some have added more fuel pressure and have gotten as high as 800+cc/min during other tests.

If you use the stock WRX 45 psi of fuel that the FPR produces, than you will see around 740cc, if you dimple the top and add 10 psi of pressure than you will see 800cc.
