Supra's have a side feed fuel rail while HKS rail is top feed. I read some tech article somewhere saying that side feed rails are better for some reason. I believe it was better spray pattern or something. Side feed injectors are more complex than top feed ones. Therefore, they cost more. I was visiting Directed Engineering's website and it stated that side feed rails are safer. Can someone or DE can explain any of these?
