I talked about this before I know, but I am really eying this engine. Ford Racing offers a 2003 Ranger 2.3L Duratec crate engine assembly. It's still 140 cu. in but with a DOHC. 135 HP 5050 RPM and 153 ft./lbs of torque @3750 RPM. It has 9.7:1 compression ratio, and the calibration code is 3G-291-AA what ever that means. MSRP $2,295.00. Would I have to put in all Ranger electronics to use this in my Mustang? Are these as tough as the factory Mustang 2.3L? Has anyone ever tried turbocharging on of these? Would forged pistons from Racer Walsh work in the Ranger motor? Racer Walsh has headers for the Mustang and the Ranger. Since this is a Ranger motor, would a Ranger header fit in the engine bay or would I use a Mustang header? Sorry for all the questions, but I'm losing sleep over them.
