Message	They say there is about an 18% drop in HP from measured at crank compared to RWHP, so I'd say you need at least 615cc. I do think the yellow top Nismo injectors flow to 615cc. They have them listed as such: Nismo 555cc(615cc) Fuel Injectors (6) on Z1's webpage. You can definitely get over 400HP with those injectors, but need lots of upgrades to get there. You don't want to max out your injectors. Getting those numbers on pump gas safely will take some doing.
