I think people are moving towards the huge ones as the price difference is pretty much nothing. I think 2000cc ones were like $10 each more expensive for me. I originally went 2000cc injectors but due to 3.oL bottom end the Plazmaman Plenum sits very high in the engine back and the Fuel Rail was fouling on it as the 2000cc's were too tall. So we went smaller. Id say they would be close to their limit though
