reamer Posted August 18, 2019 Share Posted August 18, 2019 Anyone tried to put a 3.5 EcoBoost in a Bullnose? Possible? Link to comment Share on other sites More sharing options...
85lebaront2 Posted August 18, 2019 Share Posted August 18, 2019 It could probably be done, but you would need a running, or previously running, truck with the EcoBoost powertrain as a donor vehicle, one totaled by either being hit in the rear or rolled so that all the front end area is good. You will need the complete powertrain, radiator, intercooler, all the underhood wiring, computers etc. You will probably have to buy a bypass module for the anti-theft system. Fuel pump, later Ford systems are "returnless" and the fuel pressure is monitored and sent to the computer via a fuel pressure sensor. The pumps are what is called "pulse width modulated" where the computer essentially controls the fuel pressure by how long the power pulses are in relation to the off pulses. 100% is full power, 50% is half power. This allows the computer to control the fuel pressure rather than having a mechanical fuel pressure regulator. On a forced induction system the delta pressure (fuel pressure over manifold pressure) is maintained at a constant value. An example, my turbocharged Chrysler 2.2L runs 55 psi static or delta pressure, at high vacuum conditions this may drop to 33 psi, under 15 psi boost, it climbs to 70 psi. I believe the EcoBoost engines are direct injection (right into the cylinder) and may run much higher. Motor mounts would probably have to be custom, easiest way would be to find a way to attach the EcoBoost truck's perches to your frame. Link to comment Share on other sites More sharing options...
Gary Lewis Posted August 18, 2019 Share Posted August 18, 2019 Bill's right on all counts. But it would be a nice engine to have. I love my 3.5L EB. Link to comment Share on other sites More sharing options...
