What switches over from a 90-92 SD TPI to a HSR?

I think computer, wireharness, throttle body, injectors, throttle cable and mounts. I am just gonna replace all the sensors since I am a mechanic, I get killer deals on them.

Am I forgetting anything?

 

Easier to answer the other way around...everything but the intake, fuel rails and lines, plenum, and fuel pressure regulator comes over from the TPI setup.

 

I know what I dont need, I need to know what I do need.

If that makes sense. I'm switching from TBI to a HSR.

I also need the pump.
