is there any difference in the fuel rails? i can get a good deal on a fuel rail from a 4g63t... although, no injectors, or anything included, jst the rail... i wanna know if the rails are the same.. if so, then theres no need to buy it, but if theyre different, what is it? im looking to be able to just swap the injectors into the 4g63t rail, and totally replace my current one... lemme know if thats possible.
