Hey guys i am new to the sight but have some questions. First the RCD sight has injectors but they are in "mm" where as Elites are in "cc" what is the difference? Second any one out their using RCD injectors, turbo or both ? What do you got and do you like it ? Third i would like to have a fast street truck i was thinking about doing 190 injectors what turbo should i go with ? Vgt or not which is better ? Sorry about all the questions but i figured that is why i joined to ask questions that i have so any input would be help full thanks.
