im looking to convert to a tpi from my tbi... what is EVERYTHING i need, like a list of ingrediants, that i need for this conversion. i know of the plenum, runners, manifold, ECM, harness. Im buying a bigger throttle body so i dont want the stock one anyway. Ive heard something about a fuel pump, is there a different pump for the TPI than the TBI???

 

TPI work at a higher fuel pressure than TBI, you will probably need a different fuel pump.

 

Fuel rail, with injectors, sensors,; I also heard something about the distributor being diferent? I might do the same thing to my car but I was thinking that there are a lot of upgrades to do to a TBI system (similar ones to a carbed) , but TPI will be more driveable, bettere gas mileage blah blah.
PS What is the difference between a MAP TPI and SPEED DENSITY TPI?

 

im not entirely sure man, i know one used an MAF sensor and one dont though, that i do know
