I want to upgrade my 4g dpfi to a mpfi but I have some spare parts form my 5g I was wondering if I could use it. 5g intake manifold, fuel injector, and header? I know you could use the intake manifold but I was wondering if I could use the injector because somebody told me that you could use it but just don't use the resistor box. any info would be appreciated.

 

yes yes yes, and somebody told you correctly.
