i havea stang and im lookin for a engine swap. so questioniswhat the difference between engines. could i use the cobra ecu? any response wouldbe helpful
ECU will be the biggest challenge. Otherwise, some differences are the cast vs forged crank, intake, exhaust cams, 8 bolt vs six bolt on the flywheel. There are a couple other small things. What year Stang are you contemplating doing this to?dahkid said:i havea stang and im lookin for a engine swap. so questioniswhat the difference between engines. could i use the cobra ecu? any response wouldbe helpful

Get a used engine from and 03/04 Cobra. It has completely forged internals including H beam rods. It also has a cast iron block for strength with the s/c. The compression is about 8.5 to one. There are a lot of those running 15 to 20 lbs of boost and living well if you don't take them on a long high speed run. Less than 15lbs seems to be just fine all day long. They are very, very easy to get 500 rwhp out of with a torque curve that is damn near flat.
