Message	Do it right or do it twice, as they say. Nismo is the only reliable option for side feed injectors. Stay away from 555 or 615 as they have no upside. The 740s run fine on otherwise stock motors, have plenty of capacity for future upgrades, and all the chip vendors sell base tunes for them. The stock fuel rail is more than adequate. You'll need adapters as well as a new chip tune.
