What if you already have gotten rid of the cat converter and have a cat back exhaust with high flow cat downpipe? Plus a tune obv.Hi,
Any bigger cam should be for racing only as it will put too much unburnt gas into the catalytic converter. Also it will move the torque band up 500 to 1000 rpm so you actually lose low end torque on the street. Probably lose 5 mpg also. That said it would be a real screamer with big exhaust and boost, need a custom tuned ecu.
Gonna take a lot more mods than just a cam & tune to run a 9.2 in an EBM!!!!a company called esslinger engineering has been making parts for the old 2.3's for ever and released cams for the ecoboost if i remember right it ran a 9.2 in the 1/4 mile just with the cams and tune. i think it's a $1000
