G'day guys, i just got a call from ezy gas. my 5 ltr was due to get vapour system installed, but they called me and said that they cant do vapour systems cause of the injectors not fitting on the head or something along the lines of that. He also said that they fit this system onto 5.7 ltrs. Difference? when i first bought the car (march 08) i did research and a lot of guys had this system already fitted? are these guys bull****ting me around? or is this the truth? their expecting my call by 2morrow lunch, my plans were to do some work on the car in the future. they offered to fit the mixer (sprint) system for me..which i dont really know about, can you do work on this system? whats the peformence like? thanks guys.
