I can get you a set of used 555cc side feed injs for $400 shipped. they are in new condition. If you buy 50lb injs and rail the price will be about $350-$400. The 555cc injs will fit right in the stcok rail with a cleaner look.deadly200sx said:yhea thanx i new that already. i have been looking for a z32 or cobra maf, for a while. and 50lb inj w/ rail, if u know any one help me out thanx.
